EWSA is losing millions of money in water lost during distribution to clients.
EWSA incurs an annual loss equivalent to between 30-35% of its total revenue collections from water supply to its clients.
The training that will last ten days is held in collaboration with JICA (Japan International Cooperation Agency).
Water distribution in Rwanda suffers challenges including Physical loss- water actually lost through leakage and wastage.
Leakage is the water lost from storage reservoir, transmission main, service reservoirs, and distribution system and house service connections through leaks from cracks, holes or joints of pipe lines and due to corroded pipes, and fittings in house service connections.
While Wastage is the operational loss and the wasteful use and misuse of water by the consumers.
Wastage of water can also occur due to discarding of stored water when fresh water supply comes in the case of intermittent water supply system.
Operational loss is the water used in the system for cleaning of filter beds by back washing, sludge removal from clarifiers, periodic cleaning of the service reservoirs, periodic flushing of the deposits in the transmission mains and distribution pipes and water lost during attending bursts, leaks and other repair works.
Nonphysical loss is the quantity of water lost due to the mechanical errors in meters at the source, at various points in the water supply system and at the consumers’ connections, which are recording lesser quantity of water than the actual quantity of flow.
Human errors in reading or recording the meter reading lesser than the actual quantity, and Flow through illegal connections, which are not accounted and billed for Nonphysical loss of water is considered as the loss of revenue.
