Centre scales up project to clean toxic drain

The project involves scientists from the Indian Institute of Technology-Delhi and National Environmental and Engineering Research Institute, a CSIR body.

The Department of Biotechnology is planning to scale up a pilot project that will convert drain water into potable water as well as integrate into a system to produce fuel and fertiliser.

The collaboration, which involves the institutions from The Netherlands as well Indian research institution will also aim to implement such treatment systems in other Indian states, according to officials.

The Local Treatment of Urban Sewage Streams for Healthy Reuse is a programme being tested in New Delhi's Barapullah drain that is now a repository of 125 million litres of sewage water per day. The government, on Monday, approved a project to test a treatment plant that will clean 10,000 litres a day. The plant is expected to be functioning within two years.

“This is part of a 5 year initiative,” said Renu Swarup, Secretary, Department of Biotechnology, “We are also in talks with other states to implement this technology at major drains.”

The project is now located in the vicinity of the drain and installed on land provided by the Delhi Development Authority. “The major challenge is also having several stakeholders on board — local authorities, getting land, funds,” said K VijayRaghavan, Principal Scientific Advisor, “Along with technology demonstration, this project can also show how various stakeholders can work together.”

The project involves scientists from the Indian Institute of Technology-Delhi and National Environmental and Engineering Research Institute, a CSIR body.

“This pilot scale facility will employ multiple technologies so that the data generated at the pilot scale becomes a tool-box of treatment technologies for replication at other sites in Delhi as well as other parts of India where similar drains exist. The rationale is that the mixing and matching of technologies from this tool-box will depend on the quantity (flow rate) and quality (pollutant load) of drain water, land availability, site accessibility as well as topography,” said a press note.
