BANGALORE, India - The Water Supply and Sewerage Board of Bangalore has selected SUEZ to support the city in the improvement of wastewater infrastructures for two million inhabitants of Vrishabhavathi Valley’s district.
The group will be in charge of the building of a new wastewater treatment plant of 150,000 m3 /day, the rehabilitation of an existing plant of 150,000 m3 /day and the building of a sewage sludge recycling and recovery plant coming from these two plants.
The building contract will be followed by a 10-year period of operation for a total revenue of 82 million euro.
Bangalore, known as the Indian Silicon Valley, has experienced a growth of 45 percent of its urban population in a span of five years, crossing the 12 million population mark in 2016.
This rapid urban rise combined with the development of business activities has led to an explosion of the demand for drinking water supply and sewage disposal.
During the first three years, the group will design and build a new wastewater treatment plant with a capacity of 150,000 m3 /day. Equipped with activated sludge process (bacterial treatment), the plant will treat effluents to achieve an optimum discharge quality into the Vrishabhavathi River in accordance with the most recent standards of the Indian authorities, requiring in particular a total nitrogen content of less than 10 mg/L.
The common sludgetreatment plant for the two treatment plants will be equipped with SUEZ’s Degrémont® technologies (SedipacTM and Digelis™) that will recover into electricity the biogas produced in order to make the plant self-sufficient.
Marie-Ange Debon, deputy chief executive officer of the SUEZ Group, said: “The long partnership between SUEZ and BWSSB is based on a common commitment to offer quality drinking water and wastewater services to Bangalore’s inhabitants.”
