Waste water is the water whose quality has been degraded due to actions of humans and other environmental factors. They are harmful for humans and other useful life forms which live in water like fishes. Its management is important as it kills the aquatic life present in water and affects our environment adversely making it unhygienic. We can't use waste water directly. We need to treat it properly before it can be used by humans for domestic use.
