Water management is an extremely challenging task for RCF, particularly at Trombay unit. RCF Trombay Unit is situated in the highly populated Mumbai City. In case of any shortage of water in the city especially during summers, supply of water to industries like RCF is curtailed first.
In order to be self-reliant and as a responsible corporate, we endeavour to achieve highest levels of efficiency in water consumption. We have set up first-of-its-kind Sewage Treatment Plant at Trombay unit, which treats the city municipal sewage. The plant produces about 15 MLD (Million Liters per Day) of treated water, substituting about 55% of the total water requirement at RCF, Trombay.
We have set-up another Sewage Treatment Plant (STP) at Trombay. This new STP will not only make Trombay unit self-dependent in terms of process water requirement, but also the surplus water will be supplied to adjacent factory of Bharat Petroleum Corporation Ltd. (BPCL). The New plant has a design capacity to treat 22.75 MLD of Municipal Sewage and produce about 15 MLD of treated water.
STP is a unique example of meeting industrial water requirement through Sustainability Development Project.
It is of great help to residents of Mumbai and society at large, as about 15 MLD of potable water which would have been supplied for industrial usage, is made available for the domestic use. RCF's unique initiative of treating raw sewage in STP has led to enhancement of water availability to low-income group and slum areas, where more than 75% of the residents are considered as Water Deficient Households.
In a way STP of RCF also helps in dealing with huge quantity of sewage generated in Mumbai City by treating 22.75 MLD of sewage at our Sewage Treatment Plant. This helps saving on account of cost of sewage treatment and sewage transportation.In our both STPs about 45 MLD sewage is treated and is indirectly making total 30 MLD of water available to residents of Mumbai.
The new Sewage Treatment plant has been commissioned on 10th September 2019. Presently sewage is being taken from the existing sewage pumping station. The new sewage pumping station is on the verge of completion.
