17/23

The current 8% loss of Pilot DMA can be reduced further by

Adopting Best Practices to reduce leak repair time

Close controlling on commercial losses by schedule accuracy testing of

customer meters

JUSCO has achieved reduction in NRW in pilot DMA from 31% to 8% within

12 months. Initiatives learned from the pilot DMA will be rolled out for other

existing DMAs

Challenges & Mitigation Strategies


18/23

Difficulties faced

Metering: opposition from public due to political

reasons

Illegal connection drive: political interference

Delay in payment from consumers for new waterconnections

Opposition from Very high water consumption

cases (5 %)

No support from Government for new area

connections


19/23

Strategies how to Overcome the Problems -

Challenges and Solutions

Discussion with public, politicians - more intensecommunity engagement

No penalties for un-authorized connections found duringmetering

No billing based on meters for first 3 months, so thatconsumers can assess meters / consumption pattern

Reduced meter rental cost

Reduced Tariff structure

Train DMA Managers on identification and measuring

leaks, overflows, illegal connections Amnesty Customer friendly disconnection program
