Urban water supply, Industrial Water Supply and Sewerage Projects
India’s future growth is clearly pegged to the quality life in the urban areas. Today there is a growing need for development and revamping of urban water supply and sewerage systems. Principally, the focus would be to reduce the inefficiencies (both technical and managerial), thereby bringing the high quality service at an optimal cost to the consumer.
