WsReservoir represents a location or structure designed for the storage of water within the WaterSupply network (eg Reservoir, Suction Tank). When constructed on a hill, by virtue of being a large elevated volume of water, reservoirs also maintain pressure in the network below them.The Water Supply network is a pressurised system that distributes potable or non-potable water to properties for the purposes of consumption, irrigation and firefighting.It is spatially abstracted to an area and is a child on the Water Supply network.IDS-compliant WsReservoir data will be inserted via the WsReservoirStage table.When deleted or edited, the record is Archived.
