Government of Karnataka


Biodiversity Parks are nature reserves that not only conserve natural resources of an area but

have educational and cultural value too – especially for environmental sustenance in urban centres.

Establishment of a Biodiversity Park at Madivala Lake is an excellent way of conserving and

developing the lake from degradation and maintaining its natural quality. The Biodiversity Park would

not only give life to the lake but would also preserve rare endemic native plant and aqua animal

species by creating a conducive ecosystem. The plan for the Madivala Biodiversity Park would not

only help conservation of the lake but would also promote environmental education and awareness. A

unique Nature Interpretation Centre would expose children and youth to critical knowledge and

information on biodiversity and sensitize them on importance of sustainable development of our

state. In the long run this would also lead to regaining the lake in the Garden City. The Biodiversity Park

in Madivala Lake System would be one of those very few in the country and thus Karnataka would be

taking a major lead in this environmental and ecological conservation.

Karnataka Jnana Aayoga (KJA) is a unique platform of professional experts who are bringing

new and innovative knowledge inputs and interface with various departments of GOK and society of

Karnataka. Members of KJA are investing considerable time and efforts in bringing a host of

recommendations to the Government – including this Biodiversity Park. I am thankful to each of the

Member of KJA. I am thankful to Mr PGR Sindhia for his valuable inputs on the management of the

Park. On my own behalf, I am extremely happy that this unique innovative idea is taking fruit for

implementation.

I am sure that this Madivala Biodiversity Project, which has been much inspired and motivated by

Hon'ble Minister for HE and Tourism Shri Deshpandeji, will be successfully implemented and will not

only bring benets to the people of Bengaluru but also a great satisfaction to the Government for an

excellent governance activity.

FOREWORD

Karnataka Jnana Aayoga (KJA) is a unique “platform” established by Government of Karnataka

as a body of experts and professionals in various elds who, together, bring a wealth of knowledge

and expertise through new ideation, undertake extensive brain-storming and wide consultations on

important and relevant issues for the state's development. Tasks of KJA are mainly “proof-of-

concept” and get “anchored” with one or more departments of GOK – so that after proof-of-concept

stage by KJA, executive implementation can get effectively coordinated by relevant departments of

GOK.

In the last few months, KJA has actively initiated many new ideas and knowledge inputs in

coordination with various departments. One of the major initiatives has been in the environmental and

ecological knowledge arena – the aim being to show how simple knowledge-steps can make a

signicant impact in addressing environment and towards greener-Bengaluru. KJA has ideated for

establishment of a Biodiversity Park in Madivala Lake – as a major conservation step for the lake and

also as a major area for education and tourism impact. The Biodiversity Park is a unique “controlled”

landscape where ecological assemblages of native plants and animal species in the form of biological

communities are recreated as self-sustaining ecosystems. Such bio-parks are extremely relevant in

urban environments where stress of urbanisation and development cause negative impacts and the

biodiversity parks become a reversal mechanism.

Taking cognizance of the benets of setting up of biodiversity park, Karnataka Jnana Aayoga has

coordinated with Forest/Ecology department, Lake Development Authority, Tourism Department, HE

Department and many other experts to design and recommend this biodiversity Park as a rst of

sustainable ecosystem in Madivala Lake. The ideation can easily be replicated in many other

degraded areas and can be a societal impetus to conserve and sustain the environment. KJA has

brought in the intellectual expertise and knowledge of Prof. C.R. Babu – who has implemented such

projects successfully elsewhere – I am thankful to Prof Babu.

On behalf of the Members of KJA, it is a matter of great pleasure that the project recommendation

is being submitted to GOK and will soon be implemented.

Establishment of Biodiversity Park

he Government of Karnataka reconstituted Karnataka Jnana Aayoga (KJA) in December 2013 under Tthe Chairmanship of Dr. K. Kasturirangan. The main aims and objectives of KJA are to recommend

actions for institution building, policy innovation and excellence in the eld of education, health, S&T,

industry, entrepreneurship, research and innovation, traditional knowledge, agriculture, E-Governance,

rural development and ANY other relevant areas.

At the initiative of the Honourable Minister for Higher Education and Tourism, GoK, Chairman,

Karnataka Jnana Aayoga solicited a concept note from Prof. C.R. Babu to establish a Biodiversity Park in

Bengaluru on the lines of the Yamuna Biodiversity Park of Delhi. Prof. C.R. Babu, Professor Emeritus,

School of Environmental Studies, Centre for Environmental Management of Degraded Ecosystems,

University of Delhi, who spearheaded development of Yamuna Biodiversity Park sent a draft concept

note. Chairman, KJA discussed the Concept with Honourable Minister who appreciated and supported

the idea and suggested inviting Prof. C.R. Babu to visit Bengaluru to identify a lake. The concept was

also discussed during the KJA-Technical Committee meeting held on September 17, 2014. The KJA-TC

endorsed the concept and idea of a Biodiversity Park and noted that such a park would make

tremendous educational and environmental impact on Bengaluru. KJA-TC recommended to obtain

details of the proposal from Prof. Babu including details on scope, content, design and development,

agencies to be associated with, collaboration with GoK, funding and scheduling. Considering the ndrecommendation of the KJA-TC, KJA in its 2 meeting held on September 22, 2014, endorsed the

proposal.

For the formalisation of the proposal and identication of a lake, the Principal Secretary,

Department of Higher Education, GoK invited Prof. Babu to Bengaluru. Prof. Babu visited Bengaluru on

September 24 and during his visit he held discussions with CEO and Executive Engineer of Lake

Development Authority (LDA) to understand the Bengaluru lake system. Along with the ofcers and

Executive Engineer of LDA Prof. Babu visited three Lake Systems and identied Madivala Lake System

as the best suited lake for establishing Biodiversity Park. Subsequently, Prof. Babu sent a detailed

proposal highlighting the ecogeographical aspects of Madivala Lake System with broad action plan.

Prof. Babu, in his proposal details that Biodiversity Park is unique landscape of wilderness where

ecological assemblages of native plant and animal species in the form of biological communities are

recreated over a few hundred hectares of degraded/marginal landscape. Biodiversity Park is a nature

reserve that harbours natural heritage of the area and have conservation, educational and cultural

values, and enhance the quality of environment in urban centres. The underlying principle of the

Biodiversity Park is to recreate self-sustaining ecosystems with native ora and fauna characteristics of

the area for enhancing the quality of urban environment. Madivala lake system is best suited for

establishing Biodiversity Park as 40-50 % of the area is terrestrial habitat and about 50-60 % of the area

is the waterscape with total area of about 276 acres.

BACKGROUND

1KJA Recommendation (Feb, 2015)


Chairman, KJA briefed Honourable Minister on the proposal. To discuss on the future course of

action Honourable Minister held a Review meeting on November 29, 2014 along with ofcials of

Forest/Environment department, Tourism department, Higher Education Department and LDA. Prof.

C.R. Babu made a detailed presentation on the concept, scope, budget and time taken for completion of

the project in Madivala lake system. The proposal was appreciated and endorsed by all participants,

including the Hon'ble Minister. It was discussed that sustaining such a nature reserve would not only be

good for environment but would be a spot for tourism and also for environmental education in the state.

Prof. Babu was requested to submit a Project Report (PR) incorporating the suggested changes

by Dec. 2014. It was also discussed that the best agency in the state for administering the project was

the Lake Development Authority (LDA) – who should implement and maintain the project as per advice

of Prof Babu. LDA was asked to work out cost estimation for undertaking civil works and landscaping

and was also entrusted the work of undertaking survey map (contour) of Madivala Lake System. It was

also decided in the meeting that the KJA would once again formally consider the PR in coordination with

LDA, Forest Depar tment, and Tourism Depar tment and recommend the same to GoK for

implementation. Honourable Minister recommended that the KJA may suggest a project management

structure for implementation of the project. It was decided that the LDA would be the nodal agency of

the GoK for implementation/maintenance of the project and LDA can work out necessary interface to be

worked out with Forest Department (Annexure I).

A meeting was held on Feb. 13, 2015 between Prof. C.R. Babu and LDA and Forest Department

Ofcers (of Madivala Lake) to discuss about the Project Report. Prof. C.R. Babu suggested LDA to

include landscape budget in their project report.

Considering the decisions made during the Review meeting, Prof. C.R. Babu submitted the nal

PR (as in Part-A) and the LDA submitted a PR (as in Part-B). Going by the integrated PR the project

would be completed in 5 years with an estimated budget of INR 24.72 crores of which INR. 2.82 is for

covering the costs of elements of Biodiversity Park as proposed by Prof. C.R. Babu (as given in Part-A)

and INR 21.90 crores is to cover the costs of LDA part of the Biodiversity Park (as given in Part-B). It is to

be noted that such biodiversity parks have long gestation of visible results and thus a 5 years period is

assumed for the implementation.

The PR was presented in the 3rd KJA meeting held on January 31, 2015. KJA deliberated and

endorsed the proposal and recommended to submit the same to the Honourable Minister for Higher

Education and Tourism. KJA also proposed a broad project management structure for implementation

of the Project (Annexure II).

2 KJA Recommendation (Feb, 2015)

by

Prof. C.R. Babu

KJA Recommendation (Feb, 2015)


Dr. Kasturirangan, Chairman of Karnataka Knowledge Commission (KKC), desired to have a

Concept Note on the Biodiversity Park with the view to establish a Biodiversity Park at Bengaluru, to

serve as Nature Reserve of the city that promotes nature education among students, connect

biodiversity to the city and its people and enhance the quality of environment.

Professor C.R. Babu, who has been developing and managing Biodiversity Parks of Delhi

Development Authority, had submitted a Concept Note entitled “Development of Biodiversity Parks in

Urban landscape of Bengaluru, Karnataka – A Concept Note” to the Chairman, KJA.

The Concept Note was considered and discussed in a meeting between Hon'ble Minister of

Education and Tourism and Dr. K. Kasturirangan and it was agreed that “the Government of Karnataka

should fully support the establishment of Biodiversity Park – especially as it will benet for the

development of education, tourism, ecology etc. and will bring visible benets to the State – especially

students, youth and amongst citizens to promote the cultural, ecological and educational aspects” (6th

September 2014 letter of the Principle Secretary, Education Depar tment (Higher Education),

Government of Karnataka to Professor Babu, Annexure 2).

For the formalization of the proposal, the Principle Secretary invited Professor Babu to

Bangalore for further discussion and site selection. Accordingly, Professor Babu visited Bangalore on

23rd and 24th September 2014. During his visit, he met Dr. K. Kasturirangan and ofcials of KKC and

Lake Development Authority, Bengaluru. He, along with Dr. B.S. Padmavathi (Senior Research

Associate, KKC), and Dr. S.R. Nagaraju, Executive Engineer, Lake Development Authority, Bengaluru

visited three Lake Systems for the selection of suitable site for the development of Biodiversity Park.

After the eld visit, he also appraised the status of Lake Systems of Bangalore to Dr. Kasturirangan.

- INTRODUCTION1



Biodiversity Park is unique landscape of wilderness where ecological assemblages of native

plant and animal species in the form of biological communities are recreated over a few hundred

hectares of degraded/marginal landscape. In other words, Biodiversity Park is a nature reserve that

harbours natural heritage of the area and have conservation, educational and cultural values, and

enhance the quality of environment in urban centres. The underlying principle of Biodiversity Park is to

recreate self-sustaining ecosystems with native ora and fauna characteristics of the area for

enhancing the quality of urban environment.

Bengaluru is a rapidly expanding capital city of Karnataka state and Knowledge City of India, but

has lost its natural heritage, including lakes. The lakes are life supporting system of the city and are

dead. It has been estimated that 80 % of the tree cover in the city is contributed by exotics. The quality of

environment has been deteriorating and dust pollution is a threat to public health.

A Biodiversity Park with the following functions not only contribute to the conservation of natural

heritage but also promotes nature education and connect the biodiversity to the city and people and

hence justied for the establishment of Bengaluru Biodiversity Park.

Biodiversity Park has many functions, but major ones are as follows:

· Serve as nature reserve for the conservation of lost natural heritage of the city

· Enhances the quality of urban environment

· Serve as hub for education, cultural and conservation activities

· Connect biodiversity to the city and people

· Promote ecotourism

· Create livelihoods for local communities

· Serve as living lab for understanding the ecosystem processes and functions

· Buffer local weather and serve as sink for CO2 and urban pollutants

· Serve as adaptation to climate change

· Preserve the rare, endemic threatened plant and animal species of the area and even

ecosystem due to developmental activities

· Serve as habitat for gene pools of land races of economically important crops.

The Biodiversity Park approach is innovative one and recreates the lost natural heritage in the

matrix of urban planning and development. Biodiversity Park is a part of urban infrastructure that

promotes conservation, educational and cultural activities and enhance the quality of city's

environment and thereby enhance the quality of life.

BIODIVERSITY PARK AND JUSTIFICATION FOR THE ESTABLISHMENT OF BENGALURU BIODIVERSITY PARK2



The critical requirement for the establishment of Biodiversity Park is the ecological diversity at

the broad landscape level and as well as within the landscape/waterscape. The other criteria include the

connectivity of the site to the city and people. Based on the eld visits to three sites proposed by the Lake

Development Authority, Bengaluru and taking into account the above mentioned site selection criteria,

Madivala site is preferred over the other two sites – Agara and Bellandur lakes. Agara is a silted

dysfunctional lake fed by sewer, which presently runs below the level of silted lake which spreads over

an area of 149 acres. It does not have any terrestrial habitat except for a small elevated land at one end of

the lake. The Bellandur Amanikere lake spreads over an area of 891 acres and also silted, and receives

sewage via many interconnected lake systems. It has also a small wier and encroached on all sides.

This lake system is also dead and it does not have terrestrial habitat. Both the Agara and Bellandur lake

systems are not suitable for the development of Biodiversity Park. The third lake system – Madivala

lake area – meets the requirements for the development of Biodiversity Park.

SITE SELECTION3



In Madivala lake systems 40-50 % of the area is terrestrial habitat and about 50-60 % of the area

is the waterscape. Within the waterscape there is a substantial ecological diversity – a marsh of 20 to 30

acres at the southern end, two islands inhabited by exotic tree species communities harbouring

pelicans and a couple of land projections into the waterbody from embankment cum road on the eastern

side of the waterbody. There is a land to further east of the road. On the south western side, there are

also patches of lands to further east of the road at this zone. There is an inlet at the western tip where

some patches of land also exist. On the western side of the waterbody there is a longitudinal strip of 500

m wide, at area extends from south to north over a distance 1.5 to2 km. On the south western side there

is an extra patch of land; on the south west there is a bund that separates marsh from the waterbody. The

waterbody receives raw or treated or a mix of raw and treated sewage with high BOD levels, besides

storm water from surrounding human settlements. The outlet is connected via other lake systems to

Bellandur Amanikere lake which is under the control of Bengaluru Development Authority. The total area

is about 276 acres. Although the lake is desilted, but the ofcials of Lake Development Authority

expressed that the lake needs to be desilted again and even the marshes require desilting and

restoration. The Islands also requires restoration. The water is devoid of any aquatic vegetation.The

lled up area on the western side is planted with exotics in the form of a green belt. A nursery is also

maintained. Boating facility is created. It is managed by Karnataka Forest Department. A Range Ofcer

is managing the area. Entry into the Park is by ticket.

Because of the above mentioned features of Madivala lake, the Madivala lake area is appropriate

for the establishment of the Bengaluru Biodiversity Park.

ECOGEOGRAPHICAL ASPECTS OF MADIVALA LAKE SYSTEM4



The present marsh located at south side of water body should be made into a mosaic of

wetlands and grasslands by desilting and making low height embankments and at lands

with desilted material.

The desilted material from waterbody and other lake systems such as Agara lake, which

is close to Madivala lake, would be used to landscape the existing at strip extending

from north to south on the eastern side. The landscape should be made as undulating

terrain with the ridges, having a difference of 1 to 3 metres between high point and low

point. The landscape should be done in such a way that existing native trees should be

preserved.

Infact, Agara lake can also be developed into wetland ecosystems and connected to

Madivala lake by a developing a corridors.

A peripheral 5 to 8 m wide bamboo green shelter belt will be developed all along the

boundary of the area.

The embankment and roads on the east and west will be made greenways with

walkways.

The shoreline of waterbody, after restoration, is lined with a aquatic plants like Typha,

Phragmites and sedges; submerged aquatic vegetation and benthic fauna and native sh

ngerlings will be introduced in the waterbody. The existing boating facility will be

dispensed with, and a couple of boats will be used for managing the waterbody.

About 6 native communities will be developed on the landscaped area on the western

side. A Herbal Garden, Buttery Park, Fruit Yielding Garden and an Orchidarium will be

developed on the land available at the south eastern end of the waterbody as per the

landscape Architect's plans. Nature Interpretation Centre having oor area of about 4000

sq. feet will also be developed in this area.

The Islands will be restored with native communities and without disturbing the present

avifauna. A mosaic of grasslands, wetlands and woodland will be created.

ACTION PLAN FOR THE ESTABLISHMENTOF BENGALURU BIODIVERSITY PARK5



Game shing sites will be created on the eastern

side of the waterbody, particularly at the land strip

projected into the waterbody.

On the estern side, there are two or three land

patches. These patches will be developed into

recreational garden with mosaic of different

horticultural varieties grown in Bengaluru such as

Hibiscus, Croton, palms, roses and other perennial

shrubby and herbaceous plants. A scented garden

will also be a part the recreational garden. There are

also greenways with walking paths.

There is a network of primary (6- 8' wide),

secondary (4' wide) and tertiary (3' wide) nature

trails across the Biodiversity Park.

The western and eastern shores of the waterbody

are connected by the bund located on the northern

side.

About 6 native communities will be

developed on the landscaped area on the

western side of the Lake. A Herbal

Garden, Butterfly Park, Fruit Yielding Garden and an Orchidarium

will be developed on the land available at the

south eastern end of the waterbody.



The Lake Development Authority (LDA) will be the nodal agency to set up the Biodiversity

Park.

A Chief Executive Ofcer (CEO) should be designated for the implementation of the

project as per the Action Plan proposed and with nancial and administrative powers.

The staff consisting of a Coordinator, 2 Field Biologist (in the pay scale of Scientist 'B'), 3

Technical Assistant (as per the pay scale of Government of Karnataka) and about 10 daily

wage workers (as per the Government of Karnataka) will needed and will work at the site

and will be under administrative control of CEO. The staff will be recruited locally as per

norms of implementing agency.

The present ofce of Range Forest Ofcer of K.R. Puram Range may be used by the staff

working at the site.

A Technical Advisory Committee consisting of CEO and one Executive Engineer either

from Lake Development Authority or PWD, landscape architect and Biodiversity Expert,

one representative from the Department of Education and Tourism, one representative

from the Forest Department may be constituted under the Chairmanship of CEO to

monitor the progress and advise the eld staff. The Committee will also explore the

feasibility for securing additional funding from the Central Government and or Corporate

Sector.

The existing nursery will be utilized for multiplication and maintenance of saplings of

native trees and shrubs.

A small grants for Contingencies, Consumables and Travel are needed. The total cost will

be about Rs. 1.5 lakhs per year. The cost of implements will be about Rs. 1.0 lakh.

JUSTIFICATION9


Part- B:

Project Report by

Lake Development Authority



Lakes constitute an important component of fresh water resources in the overall perspective.

They serve as an aquifer and regulate hydrological regimes, besides providing habitats and breeding

grounds for the variety of birds, sh and other aquatic life. In the urban areas, lakes assume special

importance in providing drinking water, recreation and shing. However, due to pressure of human

activities like urbanization, industrialization etc., these lakes are often seen as main targets for

development, particularly in urban areas especially for ever-increasing housing needs. Due to these

activities, most of the urban lakes are degraded beyond point of recovery. Encroachments, siltation,

discharge of domestic sewage, weed infestation, industrial efuents are the main causes for

degradation of these lakes.

1.1. PRESENT STUDY AND OBJECTIVES

The Lake Development Authority (LDA), Government of Karnataka, is represented by the Chief

Executive Ofcer is an autonomous regulatory body created through a government order, as a

non-prot society for the regeneration and conservation of lakes in and around Bangalore within

BMRDA jurisdiction initially and now extends its services to the entire state. Its main objective is

to rejuvenate, revitalize and restore the dying lakes and protect them against further pollution.

As part of this endeavor, the LDA intends to take measures for rejuvenation and development of

Madiwala Lake in Begur Hobli, Bangalore South Taluk and the Yelahanka Puttenahalli Lake in

Yelahanka Hobli, Bangalore North Taluk.

The objective of this consultancy is to prepare a Detailed Project Report (DPR) for the purpose of

rming up the LDA's requirements in respect of rejuvenation and development of the Madiwala

Lake, Begur Hobli, Bangalore South Taluk.

LDA procured services of M/s. Niketan Engineering Projects Private Limited in association with

ClimateSD Services, for the process through competitive tendering. The contract agreement

post negotiations was signed between LDA and Niketan Engineering Projects Private Limited on

06 November 2014.

The activity commenced on 04 December 2014 through an informed joint inspection along with

LDA ofcials represented by Mr. L.R.Nagaraj, Executive Engineer and Mr. Honnayya, Assistant

Executive Engineer and representatives from the BWSSB and Karnataka Forest Department at

the lake site.

1.3. METHODOLOGY

For effective and economical management of our water resources, inputs from various areas

have to be gathered and analyzed. The following are the key parameters that have been

considered:

Inventory surveys, condition and topographical surveys;

Hydrometeorology;

Lake Hydrology;



Surface Water Hydrology;

Assessment of water resources;

Water Harvesting and ground water recharge;

Water conservation;

Evaporation and seepage losses;

Economical designs for water resource projects;

Sedimentation of lakes;

Environmental Impact

Initially, the Consultant carried out the assessing the lake characteristics. This involved

carrying out the tasks such as bottom prole, characteristics of lake water, sources of water inows,

development trends around the lake etc. In order to frame the project proposal, the nature and

characteristics of the catchments were assessed, in terms of its nature and potential to contribute to the

pollution of the lake. The assessment survey comprised of reconnaissance surveys, topographical

surveys and sampling surveys.

Based on the assessment surveys and other factors, engineering options of remedial measures

such as strengthening of lake bunds, interception of silt inow into the lake, arresting o the oating

solids ingression into the lake, improvement of lake water quality etc., are being analyzed specic to

local conditions of the lake.



Madiwala Lake is part of a lake system, which formed largely due to the natural topography of

the land. Madiwala Lake is part of a system of interconnected tanks and canals that receive the surface

runoff from the upper reaches of the southern, western sides from Gottigere, Hulimavu, Arekere and

other minor lakes, Jarganahalli, Puttenahalli, Doraisamipalaya and other minor lakes respectively.

Madiwala Lake is an intermediately lake in the series of the Lake system.

The series begins with the runoff from the areas falling between Kanakpura road (NH 206) on the

west and the rst lake in this series is Jarganahalli Lake to which the lake of Kothanur and Chunchugatta

ows from the southern side and from the eastern side of the lake adjoining the Khoday breweries joins.

From the Jarganahalli Lake the outow to the Doraisamipalaya Lake which is now converted for

developing infrastructure facilities like buildings like EMPRI, DFO ofce and other units along with the

internal roads and the balance space into a mini forest by the Forest Department. Then this drains from

the western side into the Madiwala Lake. From the southern side, the start of the inow is from the

Bannerghatta road and NICE road sector and the water overows of Gottigere, Arekere lakes from

Bannerghatta road side ad from lakes if Meenakshi, Hulimavu ows from the NICE road side into the

Madiwala Lake. These are the main source of storm water inows into the Madiwala Lake. The outows

from this Lake initially travel in Northern direction for approximately 450mts and turns to Eastern

direction and further travel for about 1700 meters before it joins the Agara Lake, Rapid development and

population expansion within Bangalore have taken a heavy toll of Madiwala Lake.

The main bund for the lake is on the Northern side of the lake. The catchment area for the

Madiwala Lake is about 11.65 sq. km. The catchment is fully developed on all the sides and comprises

of fully developed urban residential and other settlements.

2.1. PROFILE OF MADIWALA LAKE

Madiwala Lake is one of the biggest lakes in Bangalore. Its area is 114.3 ha (0.441 sq mi; 1.143

km2). It is situated in the BTM Layout at 12° 54' 28" North, 77° 37' 0" East. It is a home to many

migratory birds. This Lake is a part of Bellandur lake series. The main source of water for this lake is

from the south western side ie, from J.P Nagra/Bilekahalli side and the other from southern side ie,

Hulimavu side. These are the two major water inlet points to the lake. The lake was developed under

Indo-Norwegian Environmental Programme (INEP) during the year 1998-2002. The work was executed

by Karnataka Land Army Corporation while the implementing agency was Karnataka Forest Department

and the lake was developed and maintained by Karnataka Forest Department.

STATUS OF THE LAKE SYSTEM2



The Madiwala Lake is located in Bangalore south between Bannerghatta road and Hosur road

covering an extent of 272 acres (110.07 ha) (table 3.2). The water-spread area is about 200 acres

(80.93 ha) and the wetland area is about 72 acres (29.13 ha). Earlier the lake formed an important

landmark of the city and had a wide catchment area, which lled to the maximum water level every

monsoon.

As can be seen the above photographs, the Madiwala Lake catchment has been highly urbanized

for the last two decades. Hence, wastewater inow from these urbanized areas form the primary

source of water to the lake.

2.2. BASELINE ASSESSMENT

The objective of this task was to identify the nature and type of sources contributing to the

pollution of the lake, pollution load in terms of domestic, industrial and storm water inows into the

lakes and its seasonal uctuations. The task also involved the following activities:

F Reconnaissance survey

Detailed reconnaissance survey of the lake and its surroundings were carried out to assess the

secondary information pertaining to the lake and its surroundings such as:

Details of the existing sewerage system;

Details of the existing storm water drainage system;

Details of natural; drainage pattern of the area;

Meteorological and hydrological data of the region;

Base map of the lake etc.

F Survey of the Madiwala Lake Ecosystem

Understanding the ecological set up of the Madiwala Lake is the aspect for formulating the

remedial measures of the lake rejuvenation. For this purpose, detailed ecological surveys in terms of the

following were carried out:

Ecological characteristics of the lake

Diversity of fauna.

F Assessment of pollution levels in the lake

For the purposes of assessment, the pollution level in the lake during the reconnaissance survey

of the lake and its surroundings are done. There are two main points of entry of stormwater from the

southern and south-western side of the lake. The sewer network from the urbanized catchment of the

lake discharges sewage into the stormwater drain at both the southern and south-western side of the

lake. These wastewater discharges make way into the lake and hence are point sources of pollution.



During the period of the site visit (early December 2014) the lake water level stood at the MWL.

From the inlet, silt and oating debris enter the lake during monsoon run-off. Within the lake area, there

are miscellaneous wastes seen which leads to deterioration of the lake water quality. Lack of boundary

demarcation of lake area properly and securing the boundary of the lake by proper means may lead to

encroachment which in turn reduces the lake area. The above activities have a tremendous impact on

the lake ecology.

F Preparation of base map

The objective of this task was to prepare a detailed Madiwala lake. It indicates the boundary of

the lake along with surrounding details such as roads, surrounding permanent structures, land use etc,

The essential features of the base map were to identify the exact location of all inlet and outlet of the lake

and indicate them on the base map. The survey was got done using Electronic Total Survey Station

instrument and the survey details are assessed in detail for working out the details for the lake

rejuvenation. The topographic survey map is provided in Appendix A.

F Prole survey of the lake

Along with the base map preparation, a topographic survey was carried out to assess the

following basic features of the lake. The detailed topographic survey and its details are got done by

using Electronic Total Survey Station instrument and are connected to the MSL. As per the survey

records, the assessment of the following basic features is done:

Area of the lake

Bank levels of the lake

Water level

Bed levels of the lake so as to indicate the bottom prole

Location and level of all the inlets carrying storm water

Details of the present urbanization of the lake

Level and condition of surplus waterway

The topographic surveys comprises of surveying the grids formed at an interval of 25m

longitudinal and at 5m interval across upto a distance of 50m or encountering an obstruction point.

However, the lake bottom levels shall be determined through a bathymetric and the details provided in

the Final DPR. The location and invert levels of all the inlets owing into the lake were identied and the

levels of the outlets are recorded.



F Estimation of Silt/Sludge quantity

The bathymetric survey conducted at the site has provided the existing bed level.

Additional data is being sought in order to determine the original bed level and thereby the silt

quantity. The analysis shall be presented in the Final DPR.

F Assessment of wastewater inows

There are three major wastewater inow points to the Madiwala Lake. The rst one is the

discharges from the existing 4MLD Sewage Treatment Plant (STP) located at the south-

western corner of the lake. The second one is the raw wastewater discharges at the south-

western side of the lake (Sarakki Lake Series Inlet) and the third one is the raw wastewater

discharges from the southern side of the lake (Hulimaavu Lake Series Inlet) Based on the

available information and the prole of the inlet, ow uctuations and its seasonal variations

have been appropriately factored.

There is a 4MLD capacity UASB technology based STP of BWSSB on the South-western

side of the lake. However, the STP is ineffective in removing the organic load and can be best

described as a conventional WWTP with oxidation pond. The discharge from this treatment

plant is to the lake direct. These discharges from the STP have formed weeds in the polishing

pond located within the lake precincts. The pH values of the STP were found to be slightly

high with an average of 7.2, but still within the permissible limits. The temperature measured

during the time of sample varied from 27 to 28 °C. The Total suspended solids averaging 11 is

lower compared to the Tolerance limits, Both BOD and COD of the STP sample are well within

the Tolerance limit with almost Negligence presence of Oil and grease. However, foam

discharges were observed during the sampling. The discharges from the polishing pond are

to the lake direct.

The wastewater inows from the highly urbanized catchment of Madiwala lake form the

major inows into the lake. The wastewater inow is from two main inlet points one at the

southern end (Hulimavu Lake Series Inlet) and the other at the South-western end of the lake

(Sarakki Lake Series inlet). It is estimated that the Sarakki Lake Series inlet has a wastewater

inow of 80-100lps while the Hulimavu Lake Series inlet has a wastewater inow of 15-

20lps.

Based on the data provided, it has also been noted that the BWSSB is implementing a

sewage diversion system that would result in diverting the sewage from the Sarakki Lake

Series inlet to the Belandur Tank Sewage Treatment Plan owned and operated by BWSSB. As

per information made available, the contract has been awarded and is expected to be

completed in the next 8-10 months.



For the wastewater inows from the Hulimavu and Sarakki Lake Series, no treatment

plant has been provided at this time. However, from the reports provided by the Karnataka

Forest Department, it suggest that water quality is within the permissible limits. The electrical

conductivity of 590-620 µS/cm( 5.9 – 6.2 milli Siemens/ cm ) indicate high dissolved solids .

Low transparency indicates low light penetration. The Madivala lake water was greenish

owing to the high plankton density, which manifested in its low transparency of 51.92 cm.

The calcium and magnesium hardness of the water are high indicating hard water. Dissolved

oxygen is lower than the desirable limits, i.e below 5 mg/L. Over all the DO content of the lake

is close to the lower limiting value of 4.0 and may be due to the organic pollution due to the

sewage ow and high phytoplankton density.

F Present storm water drainage pattern

The lake receives storm water ows from the runoff during the monsoons from the upper

higher levels of the lake. The catchment for the lake is on both the southern side and the

south-western side of the lake which encompasses highly urbanized catchment. As such,

the Madiwala Lake might receive close to 200-250hours of inow per annum. The

stormwater is mixed with wastewater entering the stormwater drain from the various sewer

pipelines that lead to the stormwater drain. The total stormwater inow into the Madiwala

Lake from the existing catchment of 11.65sq.km is approximately in the range of 5,000 -

6,000 cumecs / annum at an average rainfall intensity of 10.65mm/hour. This provides a

total volume of approximately 10,000 million litres per annum and is not sufcient to sustain

the lake ecosystem. However, due to the blockage of the inow channels at various locations

and wastewater being diverted into the stormwater drains, the holding capacity of the lake

has considerably reduced. Hence, it si proposed to treat the existing inows into the lake

(including the wastewaters) and augment the lake water storage capacity.



3.1. INTRODUCTION

On the reconnaissance survey carried out, the following aspects to the lake specic were noted

and are highlighted below:

Unhygienic activities like defecation in the lake and dumping of solid wastes have led to

the pollution of lake water and also destruction of the lake eco-system.

Due to organic sludge and silt accumulation along with the oating solids, the depth of

the water body has reduced considerably, thereby reduction of the holding capacity of

monsoon run off.

The secondary treated sewage from the sewage treatment plant of BWSSB was

observed being drained into the water body. This secondary treated sewage not devoid

of the rich nutrients like nitrates, phosphates an phosphorous continuously ingress into

the water body along with the untreated sewage coming from the storm water drains

from the catchments which has given bountiful support for the rampant development of

weeds in the water body.

The lake surface is completely chocked with rampant weeds growth of diff. types.

Due to the thick weeds growth and the water surface, the water underneath is devoid of

dissolved oxygen.

This promotes the growth of mosquitoes leading to vector borne diseases amongst the

surrounding urban populace.

Odour nuisance is prevalent near the water body due to release of obnoxious gases from

anaerobic reactions.

The pollution of the lake water by continuous entry of domestic sewage has led to

adverse effects on ora and fauna and the overall eco-system of the lake.

Due to pollution of lake water, the quality of groundwater is getting affected.

INVESTIGATIONS FOR LAKE REJUVENATION3



3.2. KEY ISSUES TO BE TACKLED

Madiwala Lake is under the control of the Karnataka Forest Department. This lake has

been revived by the Karnataka Forest Depar tment under the Indo-Norwegian

Environment Programme (INEP) during the year 2002-03. The maintenance of this lake

is being carried out by the Karnataka Forest Department, which has built an ofce

premises, caretaker quarters and a nursery in the lake area for better control and

supervision.

There is a 4 MLD capacity UASB technology based STP of BWSSB on the southwestern

side of the lake. The discharge from this treatment plant is directly into the lake. The

quantum of wastewater inow to the treatment plant, the degree of treatment in the STP

carried out on the incoming wastewater, quality of the treated water let into the lake and

the quantum of treated water allowed to ow into the lake has to be obtained from the

BWSSB authorities. Upon initial analysis, the STP can at best be described as

conventional treatment with oxidation ponds with very minimal removal of organic loads.

However, upon provision of complete data by the BWSSB, a suitable solution for

improving the working of STP can be proposed. This shall be part of the Final DPR.

There is considerable quantum of dry weather ow in the storm water drains owing into

the lake, which is partially diverted out of the lake through a diversion drain. A suitable

mechanism is to be proposed to take the storm water into the lake during the monsoon

runoff from the catchments and divert the dry weather ow out of the lake during the non-

monsoon runoff.

Another important impediment to be addressed is the arresting of the oating solids and

silt carried in the storm water drains during the monsoon runoff. This has to be mitigated

by a suitable mechanism or otherwise the entire quality of the surface water, holding

capacity of the lake and the aesthetics of the lake is jeopardized.

The bund slopes at few sectors have eroded the same has to be resurrected for bund

protection.

The inlet channels are not of a dened prole and is chocked and silted up at various

sectors. These have to be corrected for its prole and lined for easy ow of monsoon

runoff.

The waste weir is damaged and the same has to be resurrected for easy runoff of the

surplus water out of the lake.



The boundary protection is made by providing of chain link fencing, which is damaged at

number of segments. The boundary protection is very essential as solid/construction/

garbage/other urban wastes are being dumped into the lake area through the damaged

chain link fencing leading to dog menace, sore visuals and foul odour. A suitable

fortication has to be provided for arresting the abuse of the lake area from the

surrounding populace.

Rampant weeds growth is seen on the surface of the water body which has led to

anaerobic condition in the lake creating odour and mosquito menace. The rampant

weeds growth that takes place is due to the presence of the nutrients collected from the

inow of the organic sludge. If this is not addressed to would leads to the destruction of

aquatic life and create an imbalance in the ecology and environment of the water body.

The sludge has to be removed by an appropriate technology or on the other hand the

weeds have to be harvested regularly through a suitable appropriate mechanism.

Park area and the children play area created have to be developed to create facilities for

the local populace to enjoy the benets of the water body.

A ring bund has been created around the lake. This ring bund has to be connected to the

main bund through appropriate bridges for creating a link. Then a proper promenade

could be created for the visiting public to go round the water body as well as create

resting places at intervals along the promenade for the aged to rest and also create

gazebos for aviary enthusiast to watch and observe the beauty of aqua-fauna and ora

available in the lake sector.



Here are the actual photographs taken during the recent site visit.



3.3. WATER SOURCES FOR THE LAKE

Madiwala Lake is part of a lake system, which formed largely due to the natural

topography of the land. Madiwala Lake is part of a system of interconnected tanks and

canals that receive the surface runoff from the upper reaches of the southern, western

sides from Gottigere, Hulimavu, Arekere and other minor lakes, Jarganahalli,

Puttenahalli, Doraisamipalaya and other minor lakes respectively. Madiwala Lake is an

intermediately lake in the series of the Lake system.

The series begins with the runoff from the areas falling between Kanakpura road (NH

206) on the west and the rst lake in this series is Jarganahalli Lake to which the lake of

Kothanur and Chunchugatta ows from the southern side and from the eastern side of the

lake adjoining the Khoday breweries joins. From the Jarganahalli Lake the outow to the

Doraisamipalaya Lake which is now converted for developing infrastructure facilities like

buildings like EMPRI, DFO ofce and other units along with the internal roads and the

balance space into a mini forest by the Forest Department. Then this drains from the

western side into the Madiwala Lake. From the southern side the start if the inow is from

the Bannerghatta road and NICE road sector and the water overows of Gottigere,

Arekere lakes from Bannerghatta road side and from lakes if Meenakshi, Hulimavu ows

from the NICE road side into the Madiwala Lake. These are the main source of storm

water inows into the Madiwala Lake.

3.4. ECOLOGICAL PROFILE OF THE LAKE

The lake along with its urban importance has ecological potential too. The following

species of ora and fauna was observed during eld visit:

Shrubs that grow are mainly Zizphus Jujuba, Datura matel, Partheium hysterophoros,

Solanum Indicum, Solanum xanthocarpum, Lantana Camara, Cassia Auriculata,

occasionally Parkinsonia aculeate.

Trees like Rain tree (Samanea saman), Gulmohar (Delonix Regia), Jaali Mara (Prosopis

Juliora) etc., Copper pond tree (Peltophorum Ptericarpum)

Herb Layer includes more hard species – Ipomoea and Grasses. Marshy/ Aquatic plants

like Ipomoea cornea grows well.

The most troublesome aquatic weed is water hyacinth. About 70% of the lake is covered

by Water Hyacinth. (Eichhornia crassipes)



The Fauna in the lake consists one or many of the following:

Birds – Lake is breeding zone for resident birds and feeding and resting place for

migrating birds. Some species are migratory and some species breeds in lakes.

Butteries – About 5 species belonging to 2 families had been recorded

Spiders – 3 species of spiders

Mammals- one striped palm squirrel and 2 species of rats/mice

Amphibians – 2 species of frogs and 1 species of toads

Reptiles – one species of Lizards, ve species of snakes.

3.6. LAKE APPURTENANT STRUCTURES

Madiwala Lake receives water from two lakes Hulimavu and Jaraganahallikere on the

upstream. With a large catchment area spread into the Hulimavu valley and

Jaraganahallikere, Madiwala Lake has the capacity to ll up to the maximum during a good

monsoon season and helps with the important wetland functions of recharging of the sub-

soil ground water table around the area. Lately the holding capacity of the lake is

considerably reduced due to the blockage of the inowing channels, illegal encroachments

in the catchment area, etc.

Construction activities in the catchment area have increased dramatically over the last

few decades due the pressure of urbanisation and pressure on land. The area has been

converted into huge residential and commercial properties without providing for the basic

amenities and infrastructure. With this, Madiwala Lake perhaps became the most

convenient site to dump the construction debris and sewage. During the monsoons, the

excess storm waters choke the drains and the weir at the outlet is blocked leading to the

mixing of the sewage with the storm water, which eventually nds its way into the lake. The

depth of the lake has also decreased due to the increased sedimentation, thus reducing the

capacity of the lake. As a result of the increased pollutants there is proliferation of rooted

aquatic plants and water hyacinth. The weed growth prevents surface aeration and

penetration of sunlight, which in turn affects the dissolved oxygen content in the lake and

consequently inuencing the biodiversity of the lakes' ora and fauna. The proliferating

growth of weeds also contributes to the spread of mosquitoes and water borne diseases.



The lake is surrounded by:

Rupena agrahara slum on the south eastern side

BDA layout on the northeastern side

STP of 4-5 mld capacity near south west end

Mud walk path & entrance to the lake on the western side

Wetlands on the southern side of the lake



View of the lake and bund from the Southern Bund

Wastewater entering the lake from the Southern side

4.1. CONCEPTUAL PLAN FOR IMPROVEMENT OF LAKE WATER QUALITY

In general, any lake rejuvenation program stress on controlling / restricting entry of

wastewater entry by installing interceptor drains to lead wastewater elsewhere for

treatment. However, storm water entry continues as witnessed in Madiwala Lake. As

commonly evident, storm water drains carry more amount of waste water than

designated role meant- carrying storm water.

As a practical measure with long term sustainability in focus, it is better advised to

convert the available waste water to enter into the lake at its periphery and allow proper

level of waste removal before being let into the main lake body. Moreover, the wetland area

abutting the main lake body provides enough area for ter tiary treatment. Therefore in

principle, there is no additional land required for construction of proposed model of bio/

ecological action facilitated treatment plant towards restoration of Madiwala lake.

As part of the integrated approach towards rejuvenation of this lake, the main focus of the

intervention is towards in-situ treatment of waste water including suspended solids at the

lake periphery. The treated water is then let into the lake, thereby actuating the lake

ecosystem function.

Primary survey shows inow of 12- 14 MLD waste water year round besides storm water

inow. A treatment plant with focus on low energy requirement, easy operation and

maintenance, required level of BOD and COD level to meet with lake ecosystem

requirements can be designed.

Sequential interventions described next:

The below system is proposed to be modelled and developed within the existing

landscape and other topographical features.

Step1: Pre Treatment: Objective of this pre-treatment is to initially remove all oating and

suspended debris in the wastewater. This can be achieved by installation of required Bar

Screen at two locations receiving waste water into the Lake. This bar screen will be placed

in with electro mechanical components which will enable timely collection of various

oating solid wastes to be automatically collected and transferred into municipal solid

waste or local composting as much as possible.

DESIGN OF ENGINEERING MEASURESFOR LAKE REJUVENATION4



Step 2: Primary Treatment: Continuous aeration is proposed through a designed long

channel, which will carry the waste water to the wetland area. This long channel placed

with diffused aerators placed on a oating platform will enable sufcient initial air contact

to actuate the bacteria population. The ow will be through gravity and will also be

provided with required byepass channels.

Step 3: Secondary treatment using modied MBBR system together with provision for

phytoremediation beds as a oating base. The core of this stage is to enable bacteria

growth to enable maximum removal of waste load from the waste water and the plant

growth above the MBBR bed further enable nutrient / contaminant absorption. The main

requirement of such treatment unit is air, through aerators. Solar photovoltaic panels can

be arranged in this area for providing necessary energy for the aerators.

Step 4: Tertiary treatment using constructed wetlands: This intended as a modied

wetland towards nal polishing and to achieve BOD and COD levels enough to let into the

lake water without any adverse effects. A series of water channels formed as a maze is

proposed for achieving this process. The water channels covering an approximate length

of 5000 meters for treatment process can be constructed within wetland area. Both sides

of the water channel are to be planted densly with native trees, shrubs and ground

(including aquatic) species, which will allow nutrient removal and to purify the water. Post

completion of water movement across the channels, treated water will enter into the main

lake.



4.2 OTHER SUGGESTED ENGINEERING MEASURES

The objective of this task is to formulate remedial measures based on the analysis of

pollution sources in the earlier section. This will broadly comprise the following;

Desilting, Dewatering and De-weeding of the lake

Structural protections

Surplus ow arrangements and waste weir improvement

Boundary protection by fencing;

Turng Protection;

Pollution prevention measures

Improving effectiveness of existing BWSSP STP

F De-silting, Dewatering and Deweeding of the lake

De-silting options are generally utilized in order to increase the storage capacity of the lake.

However, for the Madiwala Lake, de-silting is not being recommended. This is because de-

silting may increase the permeability of the lake bottom resulting in reduced water storage.

However, deweeding is suggested to be taken up on both the southern and southwestern portion

of the lake. Further, dewatering shall be utilized at appropriate locations.

F Structural protection

In order to ensure that storm water is drained safely, appropriate structural protection

measures and surplus ow arrangements are recommended based on the assessment of the

condition of lake. The measures shall also consider rainfall pattern, upstream and downstream

characteristics of the area.

F Surplus ow arrangements and improvement to outlet waterways

It is very essential for allowing ow of excess water from the lake; otherwise there are

chances of damage to the structure of the lake and of ood occurring on the upstream of lake.

Hence an improvement to the waste weir of the lake is proposed.

F Boundary protection by fencing

Chain link fencing is proposed along the periphery of the lake wherever required. The main

purpose of chain link is protection of the lake users as well as the lake from encroachment. This

also controls the illegal trespass of the miscreants from undertaking illegal activities within the



lake boundary and also from damaging the infrastructure. This also supports the security staff

to regulate the activities and protect the water body from misuse. This also helps in

beautication and improves aesthetics.

F Turng Protection

Turng shall be done along the slope on the non-water side of the bund. At the bottom of the

turf, catch drains shall be provided to drain the water to outside the bund so as not to affect the

stability of the bund.

F Pollution prevention measures

The objective of this task will be to prevent future pollution of the lake by way of taking

preventive measures for inow and silt accumulation.

This will comprise of the following activities:

Construct silt traps and screen barriers for preventing entry of oating solids to the lake;

Prevention of encroachment of the lake;

Solid waste collection and disposal from the screens of the silt traps;

Sanitary facilities;

Providing for watch and ward for protecting the water body and created structures from

human vandalism

Implementing environmental education and community participation programs, etc.

Ø Construction of Silt Traps

Normally silting up of the lakes is due to carrying of silt from the catchments area during

the monsoon, which gets deposited into the lake along with the surface water ow. The

oating solids carried by the rainwater also get deposited into the lake. This has to be

avoided for the proper retention of the storage capacity of the lake. The oating solids

pollute and choke up the lake and spoil the beauty and aesthetics.

To clean up the lake of silt and oating solids, it would be expensive and more time

consuming. Hence, it is very essential to avoid silt and oating solids entering the lake.

By providing silt traps, the silt owing through the storm water drain can be eliminated

from entering the lake. However, the silt collected at the trap locations has to be



periodically removed from the silt traps. This can be carried out at regular intervals,

which will be easy and economically viable. The same is the case with oating solids

owing through the storm water drain, this helps in maintaining the lake clean for a

longer period with minimal maintenance. The silt traps and screen barriers will be to the

drain width prevalent at the site, to accommodate the storm water ows into the lake

easily.

Ø Prevention of encroachment of the lake

This is another signicant feature in many of the urban water bodies in Bangalore.

Uncontrolled growth of encroachments, leads to the reduction in the lake surface area

thereby creating the problems of upstream ooding, obstruction to the free ow of storm

water. For protection of Lake Boundary, proper measures have to be undertaken to

safeguard the lake by putting up the fencing after clearly identifying the boundary of the

lake from the revenue records identied by Revenue Surveyors on the eld.

Ø Solid waste collection and disposing arrangements

In order to avoid indiscriminate disposal of solid waste into the lake, adequate solid

waste collection and disposal arrangements has to be recommend at storm water inlets.

Ø Public Infrastructure

A number of public infrastructure is proposed for the lake. These include jogging track

on the western and northern-bunds of the lake, public toilets, benches and play area for

children. In addition, security room and public toilets are proposed.

Ø Watch and ward for the protection of lake

Watch and ward is very essential for the protection of the structures inside the lake area.

Provision is made for security persons.

F Improving effectiveness of existing BWSSP STP

The BWSSB STP located at the southwestern side is at best working as a conventional

wastewater treatment plant along with oxidation pond. The treatment process is to be

made more effective. However, towards recommending the measures, additional data

is being collected. The activities to be carried out to improve the effectiveness of the

STP is provided in the nal DPR.



As discussed in the earlier sections, it can be summarized that the nal composition of

rejuvenation of the Madiwala Lake involved removing the sediments from the lake bottom,

development of the landscape and beautify the lake surroundings, for recreational purposes,

educating the community on various environmental aspects of lake conservation.

The present section will elaborate on the design and cost estimation of all the above

components.

F Dewatering and Deweeding

Deweeding of the lake is a physical activity that inhibits unwanted plant growth. Mechanical,

or manual, weed control techniques manage weed populations.

F Strengthening of the Main Bund

The main bund on northern side of the lake is of homogeneous earthen type with standard

slopes as per MI norms on either side of it. At present the bund requires improvement such as

proper setting of rough stone pitching and at places providing new pitching as per

requirement.

F Ring bund Formation

There is a need to strengthen the ring bund throughout to dene the shoreline of the lake and

also as a boundary demarcation with rough stone pitching on southern, western & eastern

side of the lake.

F Improvements to Storm Water Inlets and Catchment Area, Gates and Culverts

The existing storm water drains need to be improved as they have been eroded at several

places and have no lining. A culvert is provided near the southwestern edge of the lake for

entry of stormwater into the lake.

F Turng Along the Slopes

It is proposed to provide articial turng along the bund slopes. On the water side, the turng

is proposed from the MWL to the TBL and on the rear side, the turng is proposed along the

entire length of the slope. Additionally, to avoid water logging around the periphery of the

lake, a catch drain is proposed to intercept the existing surrounding drains with rectangular

type to cater the possible discharge.

COST ESTIMATION5



F Silt Traps cum Screen Barrier

To avoid silt and oating solids entering the lake, there is a need to provide silt traps and

screen barriers.

F Construction of Engineered Wetlands in conjunction with MBBR and Lake Bed

Aeration

One of the major designs that is being proposed includes having Constructed Wetlands at the

southern end of the lake. The wetlands would provide secondary-level of treatment to the

wastewater / stormwater inow from both the Hulimavu and Sarakki Lake Series. The

efuent from the treated water is let into the lake at various points across the bund on the

southern side. The constructed wetlands has been proposed for the following reasons:

The Madiwala lake catchment is highly urbanized and the stormwater inow may be

limited to only 200 to 250 hours per annum. Hence, limiting the inows to the lake to

stormwater from the Sarakki and Hulimavu lake series may not sufce to meet the lake

storage capacity.

The lake water storage capacity requires the utilization of wastewater inows from the

urbanized lake catchment along both the southern and eastern sides of the lake. And,

since the sewer network on both the Hulimavu and Sarakki areas are connected to the

respective main storm water drain, it would be prudent to utilize the wastewater ows to

meet the storage capacity requirements of the lake.

Sufcient area is available to construct an engineered wetland that would be able to

accomplish secondary-level of treatment for the inuent wastewater. A oating MBBR

system with solar-powered diffused aeration utilized along with the engineered wetland

would further improve the treated efuent quality. This would improve the lake water

quality and also contribute towards sustaining the lake ecosystem.

The engineered wetlands-oating MBBR-diffused aeration system proposed for the southern

side is based on data made available to the Consultant at this time. However, we are awaiting

additional data from various agencies. Later, upon conducting the nal analysis of the data,

the wastewater treatment system design shall be revised.

F Chain Link fencing for Periphery of Lake

The lake is already provided with chain link around the outer periphery of the lake on western

side. The main purpose of chain link is, for the protection of the users of the lake,

beautication and improves aesthetics. Hence it is proposed to provide chain link fencing on

inner periphery on western side of the lake & for the main bund on northern side also.



F Walk Way, Jogging Track, Pipe Line, Bore Well and Sump Tank

As discussed in the earlier chapters, a walkway is essential for strolling, walking and to view

the natural beauty and the pleasant environment near the lake area as it offers an excellent

spot for morning walkers and joggers. Hence, there is a need of a walkway along the northern

side and a jogger's park along the western periphery. Provision is made for water pipe line for

landscaping for garden area around the lake. Provisions are also made for bore well and

sump tank inside the garden for giving good water service to the users, to maintain greenery

of the garden.

F Public Infrastructure

Provision is made for security room for watch and ward, & a public toilet which is essential for

maintain the lake after restoration. For regulating the entry, it is necessary to provide access

control, for protection of the premises of the lake area. Inside the premises of the lake area a

public toilet is essential for use of the visiting public. This supports for keeping the lake clean

and maintain good environment. Provision of street lighting is essential for the safety of the

people using the walkway and also it enhances the aesthetics of the lake area.



F Project Costs

The total estimated project costs for rejuvenating the Madiwala Lake is approximately INR

21.90 Crores with STP and INR 9.90 Crores without STP. The abstract and the detailed

estimates are provided appended.

Annexure - I



1.2. Development of a Biodiversity Park in Bengaluru through Prof. C.R. Babu, Professor

Emeritus, School of Environmental Studies, University of Delhi for the Biodiversity Park at

Madivala Lake System, Bengaluru. It is to be noted that Prof Babu has been the key person

for establishing Yamuna Biodiversity Park in Delhi and has the full experience of

undertaking such activities.

2. KJA had also facilitated visits of Dr Manju Sharma to Mysore University (MU) and had identied a

site for the Gallery in MU, in coordination with Vice-Chancellor and Registrar. Similarly, Prof

Babu had visited Madivala lake, in coordination with Lake Development Authority (LDA) and

identied the site details. These concept notes were also discussed with Mysore University and

Lake Development Authority and have their broad acceptance for the concept.

3. KJA, in its 2nd meeting held on September 21, 2014, had considered the initial concept

proposals for the Cauvery gallery and Biodiversity park and had recommended for both of these

to be undertaken through Government of Karnataka (GOK).

4. Based on these initial concept and site visits, KJA has now received formal proposals from NASI

for the Cauvery Gallery and from Prof Babu for Biodiversity Park. This meeting is for a GOK

Departmental review of these 2 proposals and to seek guidance of Hon'ble Minister for next

steps.

B] Cauvery Gallery

5. On behalf of Dr. Manju Sharma, President of NASI (who could not attend), Dr. Niraj Kumar,

Executive Secretary of NASI and Mr. Madan Gopal, National Council of Science Museums made

a presentation on 'Cauvery- Gallery' proposal. The proposed Gallery would be established at the

Old Professor's Quarters located in Mysore University campus in Mysore. NASI has undertaken

Ganga and Brahmaputra Gallery and details of the same were presented. Detailing on the major

sections of the proposed Cauvery Gallery, Mr. Madan Gopal said the Gallery would have exhibits

on river Cauvery's journey, myths and legends, physiography, tributaries, geo-scientic

importance, biodiversity of the basin, socio-economic importance, tourism, culture, fairs and

festivals, threats to the river, conservation and restoration efforts and research. These would be

projected through interactive multimedia with diorama, animations, backlit graphic display,

RFID based interactive exhibit with graphics, interactive map browser, panel display supported

by video and interactive vir tual tour. Dr. Niraj Kumar stated that the setting up of the gallery would

take 9 months at a tentative cost of about INR 3.50 crores. He further added that the

conceptualization of the project would be done by the NASI, in consultation with KJA, and

execution will be undertaken by NASI/NCSM. The gallery would be able to have footfalls upto

1000-1500 visitors per day.

6. Dr Kasturirangan suggested that NASI is a science academy and is best suited for implementing

the same – it is an autonomous body under DST and its accounts are audited by Government. It

is also planned to have a Project Implementation Committee chaired by Dr Manju Sharma and



other KJA Members/GOK ofcials/MU ofcials. A Project Director would be identied by NASI

and they would implement the project.

7. VC, MU mentioned that the Gallery will be an important activity in the 100th year celebration of

MU.

8. The proposal was appreciated and endorsed by all participants, including the Hon'ble Minister. It

was discussed that such a Gallery will do great for tourism, education and environment and also

make awareness to young persons and citizens of the state and tourists. Good satellite images,

maps and display need to be worked out. Design of the Gallery must be discussed and consulted

in early stage and then implemented.

9. Honourable Minister appreciated the KJA initiative for the Cauvery Gallery proposal and also

endorsed the proposal made by NASI in this regard. He also noted the Ganga and Brahmaputra

Gallery work of NASI and noted that the role of Dr Manju Sharma in this proposal is key person.

He also mentioned that a positive projection of Cauvery and its history/resources/environment

and benets is extremely important. A plan for sustenance and maintenance of the gallery needs

to be also built-in – for students it can be subsidised but an entry fee concept must be built-in. He

further said that the areas for display on language, ethnic and cultural aspects can be identied in

consultation with Tourism Department.

10. Based on the discussions, the following actions were identied:

10.1. NASI to submit a DPR (Detailed Project Report) incorporating the suggested changes by

the end of December, 2014. NASI could run the gallery for three-years and by then

recommend an appropriate mechanism for the Gallery operations – through a JV or

Tourism Department or Mysore University etc

10.2. KJA can once again consider the proposal and formally recommend to GOK. KJA may also

recommend an appropriate management structure and funding mechanism for the project

implementation.

10.3. Vice-Chancellor, Mysore University, to take up action for hand-over of the site building to

NASI/NCSM for setting up of the Gallery.

10.4. Tourism Department, in coordination with Higher Education Department, could administer

the project on behalf of GOK with KJA involved in project design and monitoring and MU

involved in the project implementation.

10.5. As NASI is an autonomous body and NCSM is a central government agency, the modality

of funds transfer – either to NASI or NCSM needs to be considered. NASI may consider and

suggest best option to KJA – who can make a recommendation, appropriately.

C] Biodiversity Park at Madivala Lake System

11. Prof. C.R.Babu made a detailed presentation on the Biodiversity Park proposal and said that

there is an urgent need to bring back the natural green-heritage of the city. It would be a unique



landscape where ecological assemblages of native species in the form of biological

communities are recreated and maintained over few hundred hectares of degraded or marginal

lands. Prof. Babu also briefed about the Yamuna and Aravalli Biodiversity Parks established in

Delhi. The Biodiversity Park would act as a nature reserve that harbours natural heritage of the

area and has conservation, educational, and cultural values, and also enhances the quality of

environment in urban centres. The plan is to recreate self-sustaining ecosystems with native

ora and fauna characteristic of the area for enhancing the quality of environment. Apart from

the above mentioned functions, the Biodiversity Park buffer the local weather and serve as sink

for Co and urban pollutants and also serve as a adaptation to climate change. 2

12. Highlighting the major landscape features of the proposed biodiversity park, Prof. Babu said the

park will have mosaic of wetlands interspersed with grasslands and scattered trees, greenways

with walkways, shelter belt of bamboo thicket, shrub-land of native fruit bearing shrubs, a

shoreline community of marsh plant species, aquatic community, game shing zone, herbal and

scented garden and nature interpretation centre among others. The time estimated for

developing the lake into a full-edged biodiversity park is 5 years and Prof Babu mentioned that

the direct intellectual cost would be about INR 2.20 crores – not including the survey and

landscaping and civil-works cost.

13. The proposal of Biodiversity Park was appreciated and endorsed by all participants, including

the Hon'ble Minister. It was discussed that sustaining such a nature reserve would not only be

good for environment but would be a spot for tourism and also for environmental education in the

state. In fact, the need is for many more such parks across the state that will cause a positive in

environment – Yelahanka and Jakkur lakes were mentioned. It was agreed that similar activity

can be taken up after the Madivala project is done and a bench-mark is established. In particular,

key issues of BWSSB sewerage water ow into Madivala, civil works required etc were also

discussed.

14. Hon'ble Minister expressed his support for developing the biodiversity park in Madivala lake. It

was noted that the lake area belongs to Forest Department and that a detailed DPR would be

required. It was also discussed that the best agency in the state for administering the project was

the Lake Development Authority (LDA) – who should implement and maintain the project as per

advice of Prof Babu.

15. Based on the discussions, the following actions were identied:

15.1. Prof Babu to submit a DPR (Detailed Project Report) incorporating the suggested changes

by the end of December, 2014. LDA to prepare detailed costs for civil works, landscaping

etc and other costs and provide same. Prof Babu would be the key person to

guide/supervise and look through the implementation.

15.2. KJA to formally once again consider the DPR proposals (incorporating Prof Babu and LDA

costs) – in coordination with LDA/Forest Dept/Tourism Dept and recommend the same to

GOK for implementation. KJA may also suggest a project management structure. If

required, funds for the rst 3 months for Prof Babu can be made available through KJA.



15.3. LDA would be the nodal agency of GOK for implementation/maintenance of project and

LDA can work out necessary interface to be worked out with Forest Department.

D] General

16. Hon'ble Minister appreciated and thanked Dr Kasturirangan and specically KJA efforts to

fructify these 2 initiatives. He mentioned that KJA has identied and shaped these 2 initiatives

with its best efforts and it is now for GOK Departments to take up implementation. These 2

projects are important for the state. He mentioned that KJA should continue to facilitate the DPR

stage and must be involved in the design and monitoring activities.

17. Dr Kasturirangan, Chairman, KJA thanked Hon'ble Minister for the review and guidelines and

assured that KJA would continue its efforts with the relevant GOK departments to see that these

2 projects become successful.
