Waste Water Recycling

Roughly 5000 liters of harvested (and filtered) water is used at the AVANI campus every day for domestic activities. Although a lot of water is harvested during the rainy season, water remains a scarce good.

Besides rainwater harvesting, all the waste water generated from use in kitchens, bathrooms, toilet flushing and natural dyeing unit (entire grey and black water) is recycled through a series of anaerobic and aerobic treatment to obtain good quality water for irrigation to grow vegetables for the community kitchen.

This should serve as a prototype for the water deficient hill villages and towns to recycle waste water for for the water starved hill agriculture while saving our streams and rivers from receiving contaminated waste water and getting badly polluted in the process.
