All large scale units of the group have their own Effluent Treatment Plant (ETP) with facilities for Primary, Secondary and Tertiary treatment of effluent. In Sarigam, all small units have formed a new company - Perfect Enviro Control Systems Pvt. Ltd. and have set up a Common Effluent Treatment Plant. In India, this is the first private ETP facility set up jointly by Small Scale Industries. This effort has also earned appreciation from the World Bank. Other small units situated at Tarapur & Dombivli (Maharashtra) are members of Common Effluent Treatment Plants in their respective regions.
