Domestic Effluents - Causes of Water Pollution
Liquid waste produced daily in kitchen, bathroom and toilet are discharged directly or through canal, river or any other water body, generally without any treatment. Most of our rivers including the holy Ganges are polluted at stretches on account of indiscriminate discharge of liquid effluents.
This is because sewage collection and treatment facilities in our country are inadequate. Even in 1st class cities (Population> 1.0 lakh) only about 60% of the population has access to sewage system. Therefore, raw sewage and other effluents are discharged into rivers, lakes, estuaries add seas.
