Dallas-based Jacobs is providing preliminary design, tendering, construction supervision, testing and commissioning services on a water-reuse project that will provide treated wastewater to agricultural growers in India. The firm was selected in June by the Bangalore Water Supply and Sewerage Board to rehabilitate the 248 million-liter-per-day (66 million-gallon-per-day) Koramangala and Challaghatta Valley Used Water Treatment Plant in Belur Nagasandra. According to Jacobs, this project is the first of its kind at this scale in the region. Upgrades include the addition of a new biosolids-management facility to improve energy and nutrient recovery to ensure that treated water from the plant meets effluent discharge requirements for beneficial reuse. When complete in 2022, the plant will provide an additional level of treatment to the secondary-treated discharge from the used water treatment plant. The treated water will replenish groundwater aquifers in the Kolar region of rural Bangalore, which supplement the irrigation supply for agricultural growers.
