The drainage department of the Surat Municipal Corporation provides the necessary infrastructure to carry the sewerage from domestic and industrial establishments of the city to the treatment plants, treating it and then disposing it appropriately.


To provide a better quality of life and to make Surat a self reliant and sustainable city with all basic amenities, our commitment is for 100% coverage in terms of geographical areas and population for the year 2021, by providing a comprehensive sewerage system by the end of December 2014.

Surat Municipal Corporation has prepared a master plan for comprehensive sewerage system (more than 1425Km of sewers and 9 sewage treatment works) to serve not only the domestic and commercial but also the industrial developments for the year 2021. Wastewater generated from all this developments is collected by a network of underground sewers and pumping stations and conveyed to sewage treatment works for physical and biological treatment to meet the parameters prescribed by the Gujarat Pollution Control Board before discharge into nearest water course.

Till 2006, out of the total city area of 112.27 sq.km., 92.19 % area and 97.10 % of the present population have been covered with sewerage systems. In 2006, With the increase in the SMC limits from 112.274 Sq.km to 326.515 Sq.km the coverage of sewerage has gone down from 92% to 47%. However, due to lesser population in the extended city area, 75% population was being served by underground sewerage system, at the time of city limit extention.


The functions of the Department include Planning, designing, estimating, tendering, executing and operating as well as maintaining the sewerage systems which consists of sewerage network, sewage pumping stations, sewage pumping mains, sewage treatment and effluent disposal works etc.
