Ecological Sanitation And Recycling And Reuse Of Waste-Water
Badlapur Municipal Corporation, with its partner agencies, pioneered a unique eco-sanitation facility including recycling and reuse of waste-water, for the College of Arts and Commerce, Adarsh Vidyaprasarak Sanstha, setting a new standard in institutional sanitation.
Context




Badlapur is located in Maharashtra, at a distance of 68 km from Mumbai, and has a population of close to 200,000. The city is growing at 14% annually. Adarsh Vidyaprasarak Sanstha's College of Arts and Commerce (Senior College) is located in Badlapur municipality and accommodates degree and junior colleges. The three-storied building (ground floor and two upper floors) comprises offices, faculty rooms, a common room for female students, several classrooms, a library, multimedia room, gym, and separate sanitary facilities for staff members and students. The number of students attending senior college and junior college is about 1,500 and 1,200, respectively.
Initiative
The eco-sanitation model comprises anaerobic treatment of brown water; collection, storage and reuse of urine from urinals (ladies and gents); and reuse/treatment of water. An Up-flow Anaerobic Sludge Blanket (UASB) biogas plant for solid-liquid separation and recovery of valuable energy in the form of biogas were also installed. Also, a provision for further treatment using a horizontal flow constructed wetland system were put to use. Construction was completed between 2006 and 2008. GTZ, Seecon International, IWWA, ESF, Badlapur Municipal Council and the Board of Adarsh Vidyaprasarak jointly implemented the project.
Key Features
There is a single-storied sanitation block with independent enclosures for ladies and gents. There are sufficient number of lavatories, urinals and wash-basins for students attending junior and senior college, as well as people attending special programs such as wedding ceremonies. Specially designed, water-efficient ceramic squatting-pans have been installed. These are sealed and linked to a UASB-reactor for the safe treatment of black water, and recovery of valuable energy in the form of biogas. The UASB-reactor effluent is drained (by gravity flow) to a horizontal flow constructed wetland system for advanced treatment, before being reused for irrigation purposes. Excess sludge that accumulates in the ASB-reactor is pumped out (using sludge suction trucks) periodically. Treatment of waste-water from the toilet building uses a Decentralized Treatment System (DTS). This involves a five-stage process through a biogas settler, anaerobic baffle reactor (ABR), fixed film reactor (AF), constructed wetland, and a polishing pond to be applied as nitrogen-rich liquid fertilizer to kitchen gardens, plantations etc., after recommended storage of a month.
Impact
The project has multiple benefits which include providing access to environment-friendly and safe sanitation for 2,700 students and teachers every day, while saving water through waterless and odourless urinals and pour flush toilets. The decentralized onsite treatment system enables re-use of urine for gardening and agricultural purposes and generation of bio-gas. Environmental awareness among students and communities has greatly increased.
