The Bengaluru Water Supply and Sewerage Board (BWSSB) is preparing to launch Asia’s largest water treatment facility at Thorekadanahalli (TK Halli), located 95 kilometers from Bengaluru in Malavalli taluk, Mandya district, according to The Times of India.
This plant is a key component of the expansive Cauvery V Stage project, which aims to provide Cauvery water to 110 villages on the outskirts of Bengaluru.
The facility is designed to deliver 775 million liters of potable water per day (MLD) to Bengaluru, with an overall pumping capacity of 2,225 MLD. The project, valued at Rs 5,550 crore, is currently undergoing trial operations and involves transporting water over a distance of 95 kilometers from a reservoir that is 7-8 meters deep, to an elevation of 920 meters.
BWSSB Chairperson Ram Prasath Manohar noted that minor technical issues are being addressed. The plant is equipped with machinery from Japan and incorporates French water treatment technology, both of which have been specifically adapted to handle water from the Cauvery River. The water will be pumped to Bengaluru in three phases, utilizing pumps with a capacity of 3,500 horsepower (HP) each, capable of lifting 150 MLD. To accommodate the city’s high population density, the authorities have expanded pipelines to meet the increased demand for water.
Engineers are currently conducting trials to ensure the system operates efficiently and can handle the pressure exerted by the 3,500 HP pumps. A junior engineer at TK Halli mentioned that hydro tests are being performed to detect any potential flaws in the new pipelines.
The Cauvery V Stage Project was initially scheduled to begin in March 2023, but various challenges have led to significant delays. The new target for the project’s completion is set for August 2024.
