Project for Capacity Development on

Non Revenue Water Control of SABESP

- EFICAZ Project -

Service area of SABESP

Duration of the Project ： 3 years

Project Name and SiteProject Name and Siteslide #17



Overall Goal aimed at 5 to 10years– Water supply will be stabilized by reduction of

Water Loss in water supply area of SABESP

Project Purpose– Capacity of SABESP’s staff to control Water Loss

is strengthened

Project PurposeProject Purposeslide #18



Management and technical staffs of SABESP

understand the significance of water loss

control and acquire the essential

technologies and skills Preliminary works, on-site works and

preventive works for water loss control are

strengthened through OJT in pilot areas SABESP’s in-house training system is

strengthened

Outputs of the projectOutputs of the projectslide #19



Experts to be dispatched– Chief Advisor (Water Supply Planning)– Water Loss Reduction & Control– Water Distribution Control– Leakage Detection/Training Planning

Counterpart Training in Japan Equipment Procurement

– Equipment necessary for Water Loss Reduction Activities

Activities in 2007 Activities in 2007



1st group: 1 Director and 10 Head of Depts.– 30/9 to 06/10/2007– To understand the necessity of Water Loss control

2nd Group: 16 Managers & Leaders– 21/10 to 03/11/2007

3rd Group: 16 Managers & Leaders– 04/11 to 17/11/2007– To acquire basic skills for Water Loss Control

Counterpart training in JapanCounterpart training in Japanslide #22



Collect data concerning water loss control

Evaluation for water supply analysis

For pilot area– Direct measurement work , flow and pressure– Estimation for water supply network

For 2008For 2008



Take countermeasures like leakage detection

and repair 2nd Measurement and estimate work Plan next step and do Then 3rd Measurement and Estimate work

Key words for CountermeasuresKey words for Countermeasures

For leakage: Find it by KOBETSU ONCYOU and In any case,

repair, repair, repair immediately

For Illegal: built up proper organization to control it

For Meter Error: install proper master meter

For Meter Error: stop reducing pressure

For Social problem: keep continue approach program and

distinguish from the network to measure supply amount

For Self-use: check measurement way and try to reduce

For Revenue Water: water save campaign and review water
