Storage / Pre-settlement

→‎Construction, operations and maintenance

Usually, water will be let in to the storage reservoir every day or continuously, but when the water quality becomes too poor and there is sufficient water stored in the reservoir, the water intake may be stopped temporarily. The reservoir will have to be flushed regularly to remove the deposited silt – the frequency for this will depend on the silt content of the water and the reservoir depth. All valves in the system must be opened and closed at least once every two months to keep them from becoming stuck. Occasionally, the valves may need to be repaired or replaced, and leaks in the reservoir will have to be

fixed. Apart from some help from the water users to clean the reservoir after it has been flushed, the system requires little support from an established organization to maintain it.

'''Potential problems'''

— leaks, which should be repaired immediately;

— if the solids in the water do not settle quickly enough, coagulation and flocculation may be needed.
