What is the importance of Sewage Management in modern apartments?

It has been observed that 80% of the water that is utilised for domestic purpose comes out as wastewater. If left untreated, this results into water pollution. New residential projects in cities have adopted the evolving technologies that can treat the water to make it reusable for flushing toilets, watering plants and non-potable purpose. This process is called STP (Sewage Treatment Plant).
