Dear Murthi, use of treated wastewater is the demand of current situation existing in India. Wastewater contains a lot of contaminants which are harmful to humans hence essential to be removed before reusing the water.

If you think to segregate the water used in toilets (sewage) from water used in laundry, showers and wash basins (grey water) it will cost you more. Better to treat them together to get substantial quantity of water for reuse.

The process is simple and is divided in 3 stages Primary: to remove screens, grit etc. Secondary: Biological process to remove biological contaminants represented by BOD & COD and last stage is filtration with disinfection to remove & kill the pathogenic bacteria which are harmful for humans. In treated effluent it's essential to maintain 0.5 to 1.0 ppm residual chlorine to keep the water free of pathogens. after such treatment sewage can be reused without any limitations.

In India a number of manufacturers are available who are manufacturing these plants which are compact & cost effective. If you require such details please give me your email so I can share with you these details.
