Recycle and Reuse of Sewage Water for Industrial

grade water supply through Tertiary Treatment

Plant

Surat Municipal Corporation, Surat, Gujarat

BACKGROUND
Pandesara GIDC Industrial area; a major industrial cluster with water-based industries; is situated in southern part of Surat city.
There are approximately 600 Industries in Pandesara area, out of which approximately 130 industries are water-based industries
comprising of mainly textile processing units and chemical industries. These textile processing units cater almost 40% of total demand
of synthetic yarn made sarees and dress materials of our entire country. They require huge quantity of soft water with continuous
supply from reliable source for their process of manufacturing.

The Water demand of Pandesara industries is approximately 90 – 100 MLD, comprising about 80 – 85 MLD of process water
requirement and 10-15 MLD of potable quality water demand. Of the total demand, nearly 55 MLD is met through SMC potable water
supply. The remaining demand is met through private sources including bore wells and water tankers. Furthermore, the Industrial
units do not require quality of water as pure as potable water for industrial use, hence considering the acceptable parameters for
industrial grade water, SMC had decided to implement a project to supply industrial grade water by tertiary treatment of sewage from
the Bamroli and Dindoli Sewage Treatment Plant (STP) to Pandesara Industrial Estate.

Thus, Surat Municipal Corporation has constructed total 80 MLD (40 + 40 MLD) capacity Tertiary Sewage Treatment Plant to treat
secondary treated water from Bamroli and additional capacity of 40 MLD at Dindoli Sewage Treatment Plant in year 2021 to recycle,
generate & supply Industrial Grade Water for Pandesara Industrial Estate. The capital cost of TTP plant at Dindoli was of Rs. 139.07
Crores. The plant was commissioned in March 2021 and is functional since then. This Tertiary sewage treatment plant being the very
first of its kind in India at ULB level, Surat Municipal Corporation was again in limelight at the national stage again for its initiative
in the new direction of technical excellence. This initiative is useful in water conservation and wastewater recycling and to free up
potable water resources for non-potable purposes and this free up potable water is now being supplied as drinking water to the newly
merged area in the Surat city.

In the year 1986, Surat City limit was extended and the whole Industrial area of Pandesara was covered under new city limit. These
industries required huge quantity of soft water with continuous supply from reliable source for their process of manufacturing.
Prior to 1998, Gujarat Industrial Development Corporation (G.I.D.C.) was providing Industrial water through their network for the
duration of 6 to 8 hrs. only per day. The duration & quantity of water supply was insufficient for their requirement. Hence, in the year
1998 all the Industrial units of Pandesara formed an association and they requested Surat Municipal Corporation to provide water
supply for industrial use.
This was an opportunity for Surat Municipal Corporation to earn good revenue from one source and use the same revenue for the
benefits of citizens of Surat city to improve water supply infrastructure. Hence, Surat Municipal Corporation entered into an MOU
(Memorandum of Understanding) with Pandesara Green Environment and Water Welfare Cooperative Society Ltd. in year 1998 to
supply Industrial use water for 20/22 hrs. per day to all the member units of association. Based on the water demand of Pandesara
Association S.M.C. constructed a water distribution Station and laid pipeline network for the Industrial area during the year 1998-99.
