Water management is the control and movement of water resources to diminish the destruction of life and civilization and to widen the efficient serviceable utilisation.

Waste water generation is a major problem across the globe. Waste water comes mainly from two sources: sewage outflow from household, industrial etc and storm water originating from rainwater drainage from lawns, rooftops, roads etc.

Waste management refers to the supervised handling of waste material from generation at the source through the recovery processes to disposal and covers waste from commercial, industrial, biomedical and municipal areas.
