The Barapullah drain systems
The Barapullah drain systems discharges the waste water of 5 million New Delhi citizens into the Yamuna river. The 1.6 million Liters of wastewater that passes daily through the drain makes it the perfect experimental test site to demonstrate the ambitions of LOTUSHR.
See it as a whole, treat it as whole
Local people treating and reusing water locally, is an integral part of the social-economic change that is needed for a healthier and more sustainable urban living. The LOTUSHR technologies contribute by producing ‘fit for purpose’ water qualities that ensure safe reuse and thereby offsets societal cost for higher quality water. The indirect recovery of resources from the drain water, in the form of energy, water, fertilizers, plants, crops and building materials, adds to the social benefits and the holistic approach of the LOTUSHR program.
Pre-treated, post-treated and socially acceptable
Through the combination of three research lines safe, socially accepted water reuse becomes a possibility. The research is realized in two overlapping phases: Laboratory and small scale pilot studies and larger scale pilot studies at our Barapullah test site.
Research line 1: Developing socially accepted water reuse safety strategies
Research line 2: Sewage pre-treatment and energy recovery
Research line 3: Post treatment and nutrient recovery
Unus pro omnibus, omnes pro uno
The 3 research lines are further divided into five distinct projects which form the backbone of the research within LOTUSHR. The goals of the projects are aligned in such a way, that through joint effort the ambitions of the LOTUSHR programme can be fulfilled.
