The Department of Biotechnology, Government of India and the Netherlands Organisation for Scientific Research, the Government of Netherlands are implementing the project LOTUSHR (LOcal Treatment of Urban Sewage Streams for Healthy Reuse) (Swachh Barapullah) and is a joint Indo-Netherlands collaborative project.
The project aims to demonstrate a novel holistic waste-water management approach, that will produce clean water which can be reused for various proposes (e.g. industrial, agricultural, community use etc.), while simultaneously recovering nutrients and energy from the urban waste water, thus converting drain into profitable mines. Special attention will be paid to pathogen removal and removing conventional and emerging pollutants, a major issue mostly ignored by existing STP/ WWTPs.
DBT in consultation with DDA has identified the Barapullah drain, Sarai Kale Khan, in the state of Delhi as a demonstration site for the proposed interdisciplinary technological solutions. Barapullah is a 12.5 km long drain responsible for about 30% of pollution in the Yamuna river, collecting mainly domestic sewage and waste from small industry.

Updates on the project activities:-
LOTUSHR project was inaugurated by Lt. Governor, New Delhi, Sh. Anil Baijal along with Hon’ble Union Minister for Science & Technology and Earth Sciences, Dr. Harsh Vardhan and The Netherlands Minister of Foreign Affairs, Minister Bert Koenders on May 9th 2017.
The project has progressed at considerable pace; with construction of the onsite-test lab at Barapullah site completed. Sampling on all 20 locations have been executed for characterization of the drain water. The data will become available within the 1 month.
The drain water samples are being collected and analyzed on small test reactors in the laboratories at IIT-Delhi and TERI, the data generated shared with the Dutch partners. Ph.D. and Post Doc students from The Netherlands have also spent 3 months in India on testing of the water. Standardization of the parameters for the reactors to be installed at the site is underway.
By January, 2018, a demonstration of multiple treatment technologies (Anaerobic membrane bioreactor, Dissolved Air Floatation, Photobioreactor, and Wetland) will be initiated at the test site. These demonstrations will be running for an year to effectively test the treatment efficacy during seasonal variations in pollutant load in water.
The project will develop an innovative pilot scale plant, suitable to cope with Indian conditions in a location specific manner. The final design of the pilot plant will be scalable and modular, to fit into the highly populated urban terrain.
Lt Governor inspection visit
1. Lt. Governor Sh Anil Baijal, at a short notice took an on the spot update on the progress of the LOTUSHR project at the Barapullah Drain site, Sun Dial Park, Sari Kale Khan to take stock of the progress made in the project.
2. The goal of LOTUSHR project is to develop water treatment technologies for pollutant removal including the heavy metal as well as new and emerging contaminants which usually go undetected in existing traditional sewage treatment plants.
3. The Lt Governor Sh Anil Baijal, was also accompanied by Dr. K VijayRaghavan, Secretary, DBT, GoI, Prof. T R Sreekrishnan, Project coordinator and Dean IIT Delhi , Sh Udai Pratap Singh, Vice Chairman DDA, Sh Keshav Chandra, CEO, DJB and Sh S.B.K. Singh, Special Commissioner, Delhi Police and Ms. Varsha Joshi, Power Secretary, Delhi Govt
4. While congratulating the Department of Biotechnology, Govt of India and the Netherlands Organisation of Scientific Research, the Lt Governor gave instructions for the ensured smooth coordination of different departments involved in the project i.e. IIT Delhi, DDA, DJB. He advised that the project should be a node for government-community-science interaction and hub.
5. He also stated the benefits emerging from the project have far reaching effects: swacchata, clean water for industrial, agricultural and community use. Recycling and reuse of the of waste water for both recovery of waste and generation of gas/power would benefit all sectors and therefore all agencies Delhi Jal Board, DDA and other agencies of Delhi also collaborate and support DBT for a win-win partnership
