The Hierarchy of Water Management

ReuseUsing waste water that is of

sufficient quality for a secondary function or use

ConserveThe efficient use of water,

eliminating overuse, misuse mechanical defects etc.

RecycleWaste-water that can be

cleaned and reused as potable water using best available

technology
