Civic body draws fresh plan to generate electricity from sewage

After the failure of an earlier effort of generating power from sewage,the Pune Municipal Corporation is now again planning to undertake a similar project to generate 40 MW electricity from sewage.

After the failure of an earlier effort of generating power from sewage,the Pune Municipal Corporation (PMC) is now again planning to undertake a similar project to generate 40 MW electricity from sewage.

Some 744 million litres per day (MLD) sewage is generated,but only 527 MLD is treated before releasing the water in the river. Under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM),the PMC had taken up various projects of setting sewage treatment plant (STP) to avoid pollution of Mutha river but it had not been able to increase the capacity of sewage water to be treated.

The civic administration has now sought standing committee’s approval for signing an agreement with UK-based company Minimise to set up a project for generating electricity from sewage. It proposes to generate 40 MW electricity,release pure water in the river and make available manure from sludge. “The water and the sludge would help generate gas called Syngas which would be used to run turbines to generate electricity,” said a civic official,adding that the PMC will only have to ensure four million litres of treated sewage water to the plant every day and a plot of 24,000 sq feet for setting up the plant free of cost for 25 years.

The private firm would have the ownership of the electricity and the pure water from the plant which it can sell to anyone it wishes,he added.

An earlier effort to generate electricity from sewage water was not successful. The PMC spent Rs 1 crore for the project taken up with the help of a Japanese company at Sewage Treatment Plant near Naidu Hospital. There was plan to generate 50 KW electricity per hour but the project is non-functional. The administration claims that the plant is non-functional due to a technical snag project was a failure due to lack of enough sewage water for the plant.
