A protected side intake provides a stable place in the bank of a river or lake, from where water can flow into a channel or enter the suction pipe of a pump. It is built to withstand damage by floods and to minimize problems caused by sediment. Side intakes are sturdy structures, usually made of reinforced concrete, and may have valves or sluices to flush any sediment that might settle. Often, a protected side intake is combined with a weir in the river to keep the water at the required level, a sand trap to let the sand settle, and a spillway to release excess water. The river water may enter the side intake through a screen, and a spillway overflow may be provided. Sometimes, protected side intakes are combined with a dam and a flushing sluice, which allows the upstream part of the river to be flushed.
