Decentralised wastewater treatment system at Delwara Bhil Basti was designed by CDD (Consortium for DEWATS dissemination) for the tribal Bhil slum. It was installed with technical and financial assistance from Plan India and implemented with the help of Seva Mandir, Udaipur. The major focus of this plan was to promote hygiene practices, use of toilets and re-use of treated water. It is connected to almost 50 households and two pipes bring the wastewater to the treatment plant. It has been built for treating almost 21 KLD of household wastewater. The gram panchayat has formed a Nagrik Vikas Manch with elected representatives to take the work forward. Locals from the slum area will be soon provided training for taking care of maintenance work.


Connected through two pipelines, wastewater is brought to the treatment plant behind the slum area. It enters the three-chambered septic tank. From here it moves to the eight-chambered anaerobic baffled reactor. After this secondary treatment, it is sent to the planted filter bed. The bed is filled with three different types of filter media (white river pebbles, red stones and gravels) and planted with Canna indica. The treated wastewater is reused for agricultural and irrigation purpose for the adjoining fields.

Will be tested in December 2012
