High levels of bacterial contamination are experienced in the first 10 minutes of depressurization of an intermittent system, in some cases persisting for up to 20 minutes. But maintaining full pressure into water removes that risk.
Access to clean water with improved quantity, timing, and pressure including effective service to supply pipe ‘tail ends’.
Consumers can access more water for improved health and hygiene while saving time in queuing & carrying water. They can gainfully use the time and focus on employment opportunities..
Coping costs that consumers need to incur are reduced and they only pay for a better service.
Continuous supply reduces water wastage arising from overflowing storage systems and open taps. It saves on stored household water that is discarded when a new supply comes in because the network is renewed where needed, it also reduces losses arising from leaks in the old pipes.
Continuous supply makes possible the effective management of leakage through pressure management and flow measurement. Water conservation is also encouraged through metering and price signals via a volumetric tariff to consumers.
Operational efficiencies are achieved because of a reduced need for valvemen and a conversion of these jobs into more efficient ones of meter reading and customer care. It also makes possible the management of illegal connections.
