SUEZ has a diversified portfolio of expertise, processes and proven technologies in the wastewater segment that have helped it become a trusted partner to its customers globally. The V Valley plant is also one such an example. The project has been supported by a team with international expertise and implemented the best of processes and products like DensaDeg® and FLOPAC™ Filters.
The design of the plant is based on the following principles:
The overall treatment process is divided into Wastewater Treatment System and Sludge Dewatering System.

Wastewater is a huge resource that needs to be perpetually tapped. At V Valley, SUEZ has once again been able to successfully support BWSSB in their endeavors. This illustrates the Group's ability to provide reliable and locally-tailored solutions to the growing challenges of access to drinking water and sanitation in large municipalities such as Bangalore.
|RAW SEWAGE QUALITY||TREATED EFFLUENT QUALITY|
|TSS||100 mg/l||<5 mg/l|
|BOD5, 20 deg C||80 mg/l||<5 mg/l|
In 2016, BWSSB entrusted SUEZ with a repeat order for the Design & Building of a new wastewater treatment facility with a capacity of 150,000 m3/day at the V Valley complex. Equipped with modified activated sludge process (complete with nitrification and denitrification), the plant will treat effluents to achieve a superior discharge quality into the Vrishabhavathi river, in accordance with the most recent standards(TSS/BOD=10/10) of the Indian authorities, requiring, in particular, a total nitrogen content of less than 10 mg/L.
The work will also include rehabilitation of the existing plant of 150,000 m3/day capacity. The common sludge treatment plant for the two treatment plants will be equipped with SUEZ’s technologies (Sedipac™ and Digelis™) that will help generate green power from the biogas produced in order to make the plant energy self-sufficient.
