One of the most common sources of water pollution is the discharge of untreated or partly treated sewage in water bodies, sometimes due to improper sewage handling processes of municipal bodies.
This is very common in major cities.

Case study: ganga action plan (gap)

CASE STUDY: GANGA ACTION PLAN (GAP)

The principal sources of pollution in the river Ganga are domestic and industrial wastes.
Approximately, 1.7 billion litres of effluents flow into river Ganga each day out of which 1.4 billion litres is untreated.
The Ganga Action Plan was, launched in 1986: The main objective of the program was to improve the water quality of river Ganga.
It included diversion of wastewater flowing directly into Ganga, installing-sewage treatment plants to treat this wastewater, and other, and pollution-control-measures like solid waste management.

The plan laid emphasis on public awareness and participation to keep the Ganga clean. There is still a lot of work to be done in regard to the plan.

Sanitation in public places

SANITATION IN PUBLIC PLACES

Proper sanitation should also be maintained at public places such as bus depots, railway station, airports, malls, fairs, etc.
Since a large number of people gather at these places, the waste generated is also large. This must be disposed off properly.
Public conveniences and dustbins have been built by the government which helps in maintaining sanitation in public places.
As a responsible citizen, we should maintain cleanliness inside and even outside our homes.
