Source

Source is a description of where the water comes from. For example, you may be able to access the water from a piped network, an open channel or by pumping groundwater. Water may be pumped from a river or stream or captured in dam. Conjunctive use is accessing water from more than one source. For example, pumping groundwater and using water from an open channel. There may also be other combinations or ways to access water.
