  A recent newspaper report from Nagpur states: "The pollution in Nag river and the city's lakes has been increasing with every passing year. The Nagpur Municipal Corporation (NMC) and Nagpur Improvement Trust (NIT) reportedly turned the Nag, Pilli and Pilli rivers flowing through the city into sewage drains. Even though the condition of the lakes has become even more serious, the NMC, with an annual budget of ? 1200 crore, did nothing for the conservation of water bodies as it was depending on the government." 'What should the NMC and NIT have done to prevent this pollution and why? 

Answer:

                  The NMC and NIT should have treated the sewage in sewage plants with interceptors for harmful substances, before discharging the sewage in the rivers. As usually the rivers are used to provide drinking water to the city's residents, the drinking water has become polluted, which can cause many diseases in the residents drinking this water and using it for domestic purposes. They should also install suitable purifiers in  the drinking water supply lines to purify the water suitably, so that no water borne diseases occur.
