Treated STP can be a good resource for water supply to power plants, however; it requires to be treated suitably. Further it has to be ascertained that sufficient quantity of STP effluent is available. Already some plants operating on treated STP as make up cooling towers in power plants. Obviously treatment means cost but it should be viewed in the light of lost revenue in case sufficient water is not available. A 600 MW unit down for one day costs Rs. 6 crores in revenue lost in addition means required to preserve the plant components
