Necessity of Water Loss Control




                                                             EFICAZ Project

The real reason for Water Loss Control

   The water supply service should take social
    responsibility for environmental conservation


   The Water Loss Control corresponds to the
    development of new water resources

 Understand the existing condition

     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

 Rotate Plan-Do-Check-Action


     Take countermeasures like leakage detection
      and repair
     2nd Measurement and estimate work
     Plan next step and do
     Then 3rd Measurement and Estimate work

                                                Keep Continue・・・

Key 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
    charge system
