Makeover for Bengaluru's lifeline Thippagondanahalli reservoir
Bengaluru: Bengaluru Development Minister K.J. George said on Wednesday that ahead of the completion of ambitious Yettinahole project, which would bring water to the city, adequate measures will be being taken to treat water at Thippagondanahalli reservoir. Water from Yettinahole will be stored in Thippagondanahalli and Hesaraghatta reservoirs, before being supplied to the city.
Addressing media persons after inspection of Thippagondanahalli reservoir, he said that currently water at the reservoir has high metal content, with 800 Total Dissolved Solids (TDS) and thus unfit for human consumption. If it has to be made potable, TDS level has to be brought down to 500 and efforts are on in this regard, he added.
A treatment plant with a capacity of five million litres per day (MLD) has been set up at the Chikkabanavara at a cost of Rs 30 crore and is likely to be start functioning from January. Yet another plant with 20 MLD capacity will be established at Nagasandra, he added.
The Thippagondanahalli reservoir was designed by Sir M. Visveswaraya in order to cater to the water needs of the city and it had a capacity of 132 MLD. Later on the quality of water depleted owing to the contamination caused by inflow of sewerage water, the supply of water to the city was stopped in 2000.
Since most parts of the city faces water shortage, the state government has envisaged Yettinahole project to rejuvenate Thippagondanahalli and Hesaraghatta reservoirs to supply the water to the city. In this background, it is imperative to keep the reservoir clean and free from industrial effluents and sewerage inflow, Mr George added.
By the time water is brought from Yettinahole project to Thippagondanahalli reservoir, measures will taken to purify it in the reservoir, the minister said.
As per the report submitted by the KSPCB, Arkavathy and Kumudvathy catchment area will be rejuvenated at a cost of Rs 10 crore using wetland technology to naturally treat water.
