==Construction, operations and maintenance==

Operation is usually carried out by a caretaker. The sump must be checked daily for sufficient water inflow; any debris obstructing it must be removed, and any damage repaired. Most of the maintenance will be to the pump. The intake itself needs some cleaning and de-silting. If it caves in, or if the river or lake bank erodes, repairs have to be made. A sump inlet does not require special organizational arrangements.
