Batumi Municipal Infrastructure Development:

A matter of Resource Efficiency

What is Resource Efficiency?

If we talk about Municipal Infrastructure, we particularly talk about Water Supply, Wastewater collection and treatment as well as storm water collection and evacuation.

The efficient usage of critical resources, namely nature, (environment), water and energy need to be focused.

2

Batumi Municipal Infrastructure: from Resource inefficiency (2008) to Resource efficiency (2019)Batumi municipal infrastructure situation in 2008 was characterized by Resource inefficiency:Poor water and wastewater service qualityLimited and interrupted water supply of 1-10

hours/dayExtremely high water production and extremely

high losses of >90%No functioning wastewater treatment leading to

reduction of biodiversity in the Black SeaExtremely inefficient water supply system

depending on pumping: extremely high energy costs

Very limited willingness of Batumi citizens to pay for the poor services

Very low utility revenues and very low collection efficiency

Batumi municipal infrastructure situation in 2019: Increased Resource Efficiency:

High water and wastewater service qualitySince 2013 24/7 uninterrupted water supplySignificantly reduced water production and

NRW water (technical and commercial losses of < 30%)

Since 2013 operational WWTP leading to improved biodiversity and improved bathing water quality in the black sea

Efficient water supply system working on gravity regime, without pumping

Willingness of Batumi citizens to pay for the quality services

Significantly increased utility revenues and very acceptable collection efficiency

Concept of the Rehabilitation Project for Batumi: Water supply, Wastewater and Stormwater

6

Water Supply Reservoirs 20.000 m3 in operaion since 2011

7

Water Supply Reservoirs 5 200 m3 in operaion since 2017

8

Chaisubani Water Treatment Plant (200 l/s)

Finishing Date: November 2012

9

Sewer System Batumi-Ajara Coastline (South of Batumi)

In total more than 50 km sewers laid in Batumi City and alongAjara coastline. All buildings along the new sewers connected.

At tha Ajara coastline 6 pumping stations constructed

10

Wastewater Treatment (Phase II Investment) Innovative concept, low investment and operating costs, very good treatment results

11

Sea Outfall Batumi

12

Wastewater Treatment Plant Adlia in operation since 2013

13

Mobile Wastewater Treatment Plant in operation since 2019

14

Storm water in Batumi

Challenge Storm water

Storms lead to beachdestruction and flooding oflower parts of the city

Solution: extension of theStorm water network andadequate and continousO&M of all storm waterfacilities by Batumi Tskali

Next step: Implementation of Storm water pumping stations and transport of contaminated first flush to the WWTP

15

Construction of SW Pumping Station – ongoing project 2020

16

Construction of SW main collectors – ongoing project 2020

17

Impressions of the Project Implementation:Repair of 26 km Transmission Mains

18

2016 All customers are equipped with water meters allowingfair consumption based billing and reduction of losses

19

Evolution of volume of Water Production: Efficiency gains

20

Evolution of specific consumption/person/day 2008 – 2019

2008Specific production/capita = 2184 LCDSpecific consumption/capita = 740 LCD

2019Specific production/capita = 265 LCDSpecific consumption/capita = < 150 LCD

Substantial efficiency gain. We will see further reduction of specific production and consumption in the future.

21

Evolution of water supply to a growing number of customers (from 2013 in the new constructed water supply network)

2008: 33,000 customers (families and companies)

2019: 86,500 customers (families and companies)

22

Batumi Municipality: Green City

Energy Efficiency Program for Public Buildings, assisted by a EUR 6,8 million grant from the German government through KfW:

Rehabilitation and Energy Efficiency upgrading of 25 Kindergarten in Batumi

23

Batumi Municipality: Green City

Focus on the installation and operation of good quality equipment in order to avoid: Dysfunctionality

Damages

Non-achievement of efficiency goals

Emphasis shouldbe laid on

Proper supervision

Training and instruction ofcraftsmen and

O&M staff

AdequateMaterials and

Equipment

Appropriate Planning and

Design

AdequateOperation andMaintenance

24

Municipal Infrastructure Rehabilitation integrated in a comprehensive city development Program

Upgrading of Batumi „Old Town“

Developing Batumi into a „Green City“

Integrated concept of:

• Improving living conditions of the population

• Improving economic perspectives

• Attractive Tourism Destination

• Modern Public Transport

• Integrated Road and Transport system

• Cycling pathes

25

Assistance to Batumi Municipality and Batumi Tskali for proper project management and sustainable management of new assets

Concluding Remarks

Since 2008 the situation for the population in Batumi has significantly improved;

Since 2008 a resource inefficient situation was made resource efficient. Thisregards the usage of water and energy and the protection of the environment;

As a next step, to make Batumi even more efficient:

Further reduction of NRW (technical and commercial losses);

Further reduction of water wastage, allowing to reduce raw water abstraction andtreatment and reduced wastewater pumping;

Extension of water and wastewater networks in Batumi in order to reduce water resource

inefficiency and improving bio diversity of the Black Sea;

CO2 emission reduction through Methane captivation at Adlia WWTP;
