Central Pollution Control Board (CPCB) studies de- pict that there are 269 sewage treatment plants (STPs) in India, of which only 231 are operational, thus, the existing treatment capacity is just 21 per cent of the present sewage generation.,
Typically , for installation of a plant of 8-10 KLD capacity would cost around Rs. 2.5-3 lakhs. Decentralised wastewater treatment systems are low cost on site treatment approach but continuous operation and maintenance is necessary for the sustainability and to maintain the desirable performance of the plant.
Effluent treatment plant cleans industrial effluents, contaminated water from outlet pipes, reservoir, rivers, lakes etc and reclaim the water resource for using in different purposes. ETP are mostly installed in industries like textile industry, Medicine manufacturing, leather industry, and chemicals industry.
