→‎Suitable conditions

==Suitable conditions==

* Rivers with little sediment and bed load.* Where there is adequate flow.* At a level that allows gravity supply to minimise pumping costs.* Upstream of densely populated and farming areas to reduce silt inflow.* Upstream of cattle watering places, washing places and sewer outlets (to eliminate pollution of the water).* Upstream of bridges (to reduce velocity/turbulence).

==Construction, operations and maintenance==
