Waste water reuse: As the globe is grappling with intense water scarcity, the dumping of waste water into freshwater sources like rivers is only augmenting the crisis. Amid this, the increasing urban population is not creating matters any improved, for the reason that along with it is increasing industrialisation. The water sources in India are collapsing beneath this burden, and to alleviate this, there is a have to have to assure water provide as effectively as sewage therapy with reuse. To tackle this problem, Vishvaraj Environment Pvt Ltd and Nagpur Municipal Corporation launched a PPP model, known as Nagpur Reuse Project, and now, the project is involved in the collection of 200 million litres per day (MLD) of sewage from rivers, and treating it for reuse.
Nagpur has a population of about 27 lakh people today, and it had been working with 700 MLD of fresh water. About 80% of this water, about 550 MLD, was becoming converted into sewage, indicating the higher quantity of water sources that had been becoming wasted. Thus, Nagpur Reuse Project was the remedy – it aimed at treating the sewage and reusing that water, in an work to cut down the wastage of fresh water sources.
The work on the project, which also incorporated a sewage therapy plant (STP), started back in June 2018, and the 200 MLD STP project was completed ahead of its scheduled completion, in the middle of the coronavirus pandemic, and now it has been the biggest waste water project in the nation.
The concentrate is on collecting 200 MLD sewage and treating it for reuse. The state energy generation utility enterprise MahaGenCo has earlier agreed to use this treated water for two of its plants – Khaparkheda and Koradi – and for this, it would be utilising 190 MLD of the treated water.
Wastage of water is a key challenge that the nation is facing. To place issues in point of view, about 15,000 MLD of municipal and industrial waste is released into the holy River Ganga. The fate of other rivers in the nation is the very same, if not more. In Nagpur, the 550 MLD of waste water was becoming released into Pivali, Pohra and Nag rivers, and the Gosikhurd Dam was polluted due to this. The Nagpur Reuse Project was the outcome of the order of the High Court, which had directed that mechanisms for sewage therapy be established.
However, nation-wide efforts are on to resolve this problem. The Ministry of Power had in January 2016 produced it mandatory for all thermal energy plants to use treated sewage water if it was out there inside a 50 km radius, permitting the price connected with this to be a pass-by means of in tariff. In common also, the government is working towards cleaning of rivers, like the Namami Gange mission, so that the freshwater sources in the nation can be rejuvenated. Without adequate fresh water, sustaining human life can grow to be pretty tricky, which is why focusing on these difficulties is the have to have of the hour.
