The Delhi Jal Board, Responsible for Water Management in New Delhi, has Awarded Degrémont a DBO Contract

The Authority; The Delhi Jal Board, Responsible for Water Management in New Delhi, has Awarded Degrémont a DBO Contract (design, build, operate) to build an urban wastewater treatment plant at Delhi Gate Nalla with a capacity of 70,000 m³ per day.

This investment is part of the Yamuna Action Plan II, a bilateral project between the Indian and Japanese governments aimed at rehabilitating the quality of water in the Yamuna River, which provides over 70% of New Delhi’s water needs.

Degrémont will equip the plant with two technologies: Densadeg, a decantation process, and Biofor, a fixed-biological-culture treatment system, enabling the plant’s surface area to be limited to 25,000 m².

The new plant will take two years to build, followed by 11 years of operation and maintenance for a total sum of approximately €29 million. The treated wastewater will be reused as make-up water by local industries and the Delhi Gate Nalla power plant.

Alng with this, in what will be a first for India, the plant will be equipped with a deodorising system for the treatment of wastewater in order to limit unpleasant odours.

In a second contract, the Bangalore Water Supply & Sewerage Board has awarded Degrémont a DBO contract worth €12 million for a tertiary wastewater treatment plant with a capacity of 40,000 m³/day at Raja Canal.

Following the design and construction phase, which is scheduled to last 15 months, Degrémont will be responsible for operating and maintaining the plant for five years.

Degrémont will help the Bangalore Water Supply & Sewerage Board to tackle these new issues using its technical processes, Densadeg and Flopac, enabling the wastewater to be reused in industry. The plant will meet the water needs of the new IT and automobile park at Raja Canal, according to the company.
