Kalyan Dombivli is an important township of Mumbai City. Being close to

Mumbai, the demographic profile of the city reveals that the population has

increased continuously. Due to which, quantities of Municipal Solid Waste

generated in Kalyan and Dombivli measured by in house survey team under

the Solid Waste Management Department in year 2006, showed generation

of 510 TPD MSW from population base of 12,62,936. It comes to

403.83gm/capita/day. With population base of 1247321 in 2011, MSW

quantity was found to be 600 TPD. This comes to 481.03 gm/capita/day. At

the end of 2013, Kalyan Dombivli Municipal Corporation had 650 MT/day/

of MSW. In the view of which an integrated Municipal waste treatment

facility has been proposed. The plant at Umbarde will include a bio

stabilization facility and 350 TPD sanitary landfill with a leachate treatment

plant.

CHAPTER 2-IDENTIFICATION OF THE PROJECT AND PROJECT

PROPONENT

2.1 Identification Of The Project

Municipal Solid Waste management, to reduce the impact on the environment, requires an

integrated approach involving components such as collection from various generators,

segregation at source, recycling of the waste, reuse and disposal, etc. Healthy environment

demands an integrated approach that involves complementary use of a variety of practices to

handle the Municipal Solid Waste, stream safely and effectively with the least adverse impact

on human health and the environment. Integrated approach would be adopted to dispose the

Municipal Solid Waste generated in the city as the approach amalgamates three stages of

Municipal Solid Waste Management. The adoption of this approach would streamline the

collection of Municipal Solid Waste from diverse generating points in the city and

transporting them to the treatment facilities where it would be separated and disposed

accordingly.

The integrated approach is critically important for the Municipal Solid Waste management to

work efficiently. A well integrated approach captures the primary collection, secondary

collection, treatment and disposal.

In addition to all this, an integrated approach would reduce the littering on streets, enhance

the cleanliness of the city, and increase the viability, profitability and sustainability of

Municipal Solid Waste systems through their impact on increasing incomes, employment

while reducing pollution levels.

Umbarde facility is part of one of such integrated system. The facility includes a Bio-

stabilization facility and a 350 TPD Sanitary landfill with a leachate treatment plant.

2.2 Demographic Details Of KDMC

2.2.1 City Profile

Kalyan Dombivli is an important satellite township of Mumbai city. It is an important railway

junction. The city of Kalyan – Dombivli forms one of the important urban agglomerations of

Maharashtra state. Owing to large urbanizable zone and its proximity to greater Mumbai,

Kalyan-Dombivli is trying to enhance the quality of services, expand the infrastructure and

accelerate its economic growth. The Table provides salient feature of Kalyan Dombivli city

as on Today.

City administration Kalyan Dombivli Municipal Corporation

The city has been functioning with sustained growth in territory economic activities.

Major economic activities of the city are trade and commerce.

2.3 Brief Description Of Nature Of The Project

Municipal Solid Waste as such cannot be disposed off due to pollution problems and also due

to land area exhaustion, the project is a well planned Integrated , where the waste will be

disposed off after separation and conditioning of dry recyclable materials.

2.4 Need For The Project And Its Importance To The Country Or Region

Wherever people live and work they will generate waste and that too in increasing quantities

with changing characteristics as per the progress of economy and change in life style.

Currently Nation-wide, every urban citizen is generating 400 to 600 gm solid waste per day.

This is still 1/3 rd

to 1/4th

as compared to developed countries, thereby meaning that at many

locations, waste quantities could double within next 5 to 7 years.

Arbitrary disposal of solid waste as open dumping has been the most wide spread form of

waste management in every city of India. This practice has thrived because of the mistaken

belief that it is the easiest and cheapest method of waste disposal.

During the last few decades, deposition of waste along road side, on river banks, in marsh

lands has proved highly detrimental to the ground water and living environment. The

physical, chemical and biological contaminants in solid waste have been chocking drainage

and water flows in several part of city, building up of toxic heavy metals and poisonous

substances in the surrounding lands, This is also assuring ideal breeding ground for

pathogens, flies, mosquitoes, rodents, vermins thereby, causing new disease epidemics.

Project name: Integrated Solid Waste Management Facility at Umbarde

ABC TECHNO LABS INDIA PVT. LTD., MUMBAI 9

The collection, transportation, treatment and disposal of MSW is one of the most pressing

problems of the cities. With rapid Urbanization as a result of planned and unplanned growth

and industrialization, the problem of handling MSW has increased in alarming proportions

over past few years.

Due to rapidly increasing waste quantities, so also the influence of neighbourhood from

Mumbai, Thane, Navi Mumbai, the waste characteristics may change significantly which

necessitates technologies with multiple processing options.

2.5 Employment Generation (Direct And Indirect) Due To The Project

About 20 full time employees and 38 contractual employees will be employed for project

operation. More than 100 indirect employment will be generated for primary/secondary

collection, transportation etc.

3.5 Size And Magnitude Of Project

To accommodate the ever increasing Municipal Solid Waste, this Integrated Solid Waste

Management Facility is proposed to be established at Umbarde with a Bio-Stabilization

facility and 350 TPD Sanitary Landfill with a leachate treatment plant on 1,02,100 m2 of

land.

3.6 Project Description With Process Details:

The Municipal Solid Waste consists of many components. Hence after collection when the

waste is brought to treatment facility it is first segregated.

In a Municipal solid waste there is around 50% Biodegradable waste, 30% Recyclables and

20% inert waste. During segregation the Biodegradable waste is sent for Bio-stabilization, the

recyclables are sent for recycling and inert waste is landfilled.

(i) Bio-Stabilization:

It is a treatment of aerobic bioconversion applied to Municipal Solid Waste (MSW) as is, to

MSW residual of selective collection, or to contaminated organic fractions (under-sieve from

mechanical selection, etc.) with the aim of generating a stabilized organic fraction suitable to

be landfilled or used for capping operations during the cultivation of the sanitary landfill

(ii) Sanitary Landfill:

The Sanitary Landfill will be designed with HDPE geomembrane at bottom & sides to avoid

percolation of leachate into ground water. Leachate collection system with full-fledged ETP

with RO system is proposed for the treatment of leachates.

Following is the detailed description about the components of the Integrated Solid Waste

Management Facility:

Life Of The Landfill:

Project name: Integrated Solid Waste Management Facility at Umbarde

ABC TECHNO LABS INDIA PVT. LTD., MUMBAI 16

The primary factor that determines the design and life of the SLF is the volume of the waste

to be land filled. The new landfill site with treatment facility at Umbarde, Kalyan would

cover an area of about10.21 hectares (1,02,100 m2). As per estimates the total capacity of the

landfill will be around 350 TPD. The total volume of waste to be placed in the landfill will be

computed for the “active” period of the landfill taking into account, (a) the current generation

of waste per annum and (b) the anticipated increase in rate of waste generation on the basis of

past records or population growth rate. The required landfill capacity works out significantly

greater than the waste volume it accommodates. The actual capacity of the landfill will

depend upon the volume occupied by the liner system and the cover material (daily,

intermediate and final cover) as well as the compacted density of the waste. In addition, the

amount of settlement a waste will undergo due to overburden stress and due to bio-

degradation will also be taken into account. The proposed landfill design life comprises

of an “active” period and a “closure” and a “post closure” period. The “active” period or

the design life will be the 1st phase of land fill process (proposed project). The “closure

and post-closure” period for which proposed landfill will be monitored and maintained

after the “active period” is completed.

Basic Design Component

The landfill will be operated in phases because it allows progressive use of the landfill area,

such that at any given time a part of the site may have a final cover, a part being actively

filled, a part being prepared to receive waste and a part undisturbed. Each phase will be

designed for a period of one year and will consist of daily cells, daily cover, lifts,

intermediate cover, liner, leachate collection facility, gas control facility and final cover. Each

phase will be filled from the base to the final/intermediate cover and capped within this

period. The waste subjected to landfilling shall be compacted in thin layers with the help of

Bulldozers/ landfill compactors and the wastes shall be covered immediately or at the end of

each working day with 7.5-10 cm of soil.

Liner System :

Protection of the surrounding environment of an SLF can be effectively achieved by using an

impermeable liner on the base and sides to prevent migration of gas and leachates into the

soil and groundwater. The liner system for the proposed SLF has been designed based on

recommendation of the Ministry of Environment and Forests for construction of a non-

Project name: Integrated Solid Waste Management Facility at Umbarde

ABC TECHNO LABS INDIA PVT. LTD., MUMBAI 17

permeable lining system at the base and wall of waste disposal site area. For SLF receiving

residues of waste processing facilities or mixed waste or waste having contamination of

hazardous material (such as aerosol, bleaches, polishes, batteries, waste oils, paint products

and pesticides), the liner will have, at a minimum, a composite barrier having 1.5 mm High

Density Polyethylene (HDPE) geo-membrane or equivalent overlying 90 cm of soil

(clay/amended soil) having permeability coefficient not greater than 1X10-7 cm/sec.

Leachate Generation, Collection and Treatment:

Water that percolates through the solid waste placed in the landfill is known as leachate.

During its downward progress through the waste, the water entrains suspended solids,

extracts soluble constituents of the waste and soluble products of the waste degradation

process. The quantity of leachate generated in a landfill is dependent on the quantity of

infiltrating water. This, in turn, is dependent on the local precipitation, active area of the

landfill and the operational practices. The quality is dependent on the characteristic of the

wastes. The leachate generation from the landfill would be around 20 m3 /day. Since

primarily inert MSW will be deposited in the SLF, the generated leachate is not expected to

have contaminants such as heavy metals. However, considering accidental scenarios when

small quantity of bio-degradable material may enter the landfill as part of the processing

rejects, the leachate will be treated and disposed with adequate safeguards for the

environment. HDPE Geomembrane Layer 300mm - Silty Sand Layer

Leachate Collection System:

The primary function of leachate collection system is to collect and to convey the leachate

out of the landfill and to control the depth of the leachate above the liner. Leachate collection

network will comprise of header pipe and feeder pipes. The feeder pipes will consist of

HDPE pipes of 150 mm diameter constructed at a spacing of 50 m and at a slope of 2 per

cent. Pipe spacing is governed by the requirement that the leachate head will not be greater

than the drainage layer thickness. The feeder pipes will be connected to header pipe. The

header pipe will be constructed at a slope of 2 per cent and connected to leachate collection

tank. The feeder and header pipes will have sufficient strength and will be safe from

particulate and biological clogging and deflections. Leachate collection chamber/s will be

installed to collect the leachate through the header pipe. The leachate collection chambers

will be built up with successive lifts of waste. Submersible pumps or adductor pumps will be

Project name: Integrated Solid Waste Management Facility at Umbarde

ABC TECHNO LABS INDIA PVT. LTD., MUMBAI 18

used to remove leachate from the chambers and carried through permanent pipe work for

treatment and disposal.

Landfill gas generation, control and management:

Gas generation

Landfill gas is generated due to the degradation of the organic matter in the wastes. As per

CEEPHO manual, the principal components of typical landfill gas are methane (CH4), and

carbon dioxide (CO2) whose typical concentrations are 30-60% and 34-60% respectively.

However, considering accidental scenarios when bio-degradable material may enter the

landfill as part of the processing, adequate gas control and management systems will be

provided.

Control and management:

Adequate measures will be taken to restrict uncontrolled migration of landfill gas from the

SLF. These measures include, Gas drainage blanket provided over the solid waste as part of

the final cover of a completed phase; and Vertical gas vents in the gas-drainage blanket for

controlled passive venting of the landfill gas. The gas venting layer will be 300 mm thick and

made of granular soil. The gas will get accumulated in this layer and will be vented through

gas vent pipes. These gas vent pipes will perforated HDPE pipes be of 150 mm diameter.

Blowers will convey the gas collected in the pipes to the flaring unit. The flaring unit will

consist of collection chamber, blower, ignition mechanism, control valves and sensors. Since

the anticipated volume of landfill gas is low, utilization of the gas for either direct internal

consumption or power generation is not considered viable

Final cover

The final cover system for the proposed SLF will be based on the recommendations of MoEF

and CPHHEO and will be a composite structure comprising of four layers of an engineered

seal designed to prevent water ingress and egress of landfill gas and an agricultural cap

comprising of subsoil drainage layer. The final cover system will consist of the following

components:

Vegetative layer thick with good vegetation supporting soil

Drainage layer of thick granular material with permeability greater than 10-2 cm /sec

Barrier layer of thick clay/amended soil with permeability less than 10-7cm/sec

Project name: Integrated Solid Waste Management Facility at Umbarde

ABC TECHNO LABS INDIA PVT. LTD., MUMBAI 19

Gas venting layer of thick granular material with permeability greater than 10-2

cm/sec

A suitable vegetative cover will have to be established on the closed site to ensure slow

surface runoff, promote evapo-transpiration of rainfall, and retain moisture in the cap and

enhance the formation of a soil structure in the agriculture soil. In accordance with the

requirements of the MSW 2000 Rules the selected plants will be locally adopted non-edible

perennial plants that are resistant to drought and extreme temperatures, and have ability to

thrive on low-nutrient soil with minimum nutrient addition. Root penetration will not exceed

30 cm. Plantation will be made in sufficient density to minimize soil erosion.

As each phase is completed and as the final cover level is reached in successive phases,

interconnectivities in the leachate collection system, surface water drainage system at the

cover of each phase and the gas collection system will be established. Temporary surface

water drainage system constructed at the base of each completed phase is dismantled. Upon

completion of all phases a final check will be made of the proper functioning of all inter

connected systems. An access road will be provided on the landfill cover to enable easy

approach for routine inspection of the landfill cover

Other Infrastructural Facilities

Besides the compost plant and landfill, other infrastructural facilities have been proposed to

be developed as an integral part of the waste management facility. This would include access

road, internal roads, drainage system, boundary walls, administrative building, Leachate

Treatment Facility, buffer zone for plantation of trees etc. As per norms, total landfill area

will be approximately 15% more than the area required for land filling to accommodate all

infrastructure and support facilities as well as to allow the formation of a green belt around

the landfill. Management of Surface Runoff Surface water management is required to ensure

that rainwater does not drain into the waste from surrounding areas and that there is no water

logging or ponding on covers of landfills. The following measures will be taken for ensuring

adequate surface water drainage:

Rainwater running off the slopes above and outside the landfill area will be

intercepted and channelled to a storm water reservoir, thus preventing the operational

area of the site. The diversion channel will be provided with low permeability lining

to prevent leakage into the landfill.

Project name: Integrated Solid Waste Management Facility at Umbarde

ABC TECHNO LABS INDIA PVT. LTD., MUMBAI 20

Rainfall on active tipping areas will be collected separately and managed as leachate

via the leachate collection drain and leachate collection sumps to the leachate

treatment and disposal system.

Rainfall on areas within the landfill site but on final covers of phases which have been

completed are not actively being used for waste disposal will be diverted away in

drainage channels from active tipping areas, and directed to the storm water reservoir.

Drainage channels or drains constructed on the restored landfill surface will be

constructed so that they are able to accommodate settlement, resist erosion and cope

with localised storm conditions.

The final cover will be provided a slope of 3 to 5% for proper surface water drainage.

(iii) Leachate Treatment

The leachate will be treated in a leachate treatment plant. A part of the treated leachate will

be re-circulated in the compost plant to increase the rate of waste stabilization during the

aerobic composting. Site fencing a compound wall or rigid fencing all round the land fill site

to a height will to be constructed to totally seclude site from outside activities. Lockable gates

will be provided to prevent unauthorized access full time security guard at the site. A cattle

grid will also be placed at the entrance to the waste reception area. Site entrance a permanent,

wide, entrance road with separate entry and exit lanes and gates will be provided. Sufficient

length/parking space will be provided inside the entrance gate till the weighbridge to prevent

queuing of vehicles outside the entrance gate. The entrance area will be properly landscaped

with a green belt containing tree plantation for good visual impact. Proper direction signs and

lighting will be placed at the entrance gate. Access roads, the approach way to the facility

will be upgraded or paved sufficiently to a width for movement of two way traffic. Secondary

arterial roads and temporary roads within the site will of lesser standards, as the locations of
