CM Siddaramaiah inaugurates sewage treatment plant at Bellandur

Bengaluru: Chief Minister Siddaramaiah has inaugurated a 60-million-litres-a-day sewage treatment plant (ST) at Yamaluru near Bellandur on Monday.

The STP will be the first one in the state to generate power through biogas. With the inauguration of the STP, there will be a relief in handling the domestic sewage entering Bellandur and Varthur lakes.

The STP in Koramangala-Challaghatta (K&C) Valley was constructed with the aid of Japan International Cooperation Agency, and is estimated to have cost Rs. 205 crore.

According to the Bangalore Water Supply and Sewerage Board, the plant uses “activated sludge process with biological nutrient removal” to treat sewage water, while the residue can generate up to 1 mega watt of power within the plant.

With much of the contaminants reduced by more than 95 per cent, officials said the Minor Irrigation Department has started the process of pumping out the treated water towards Kolar district to fill the tanks there.

The plant will process the water that will be treated in the 10 MLD plant at Sarakki lake and 120 MLD plant at Agara lake, which will be connected to the K&C STP through a 11-km pipe.

After inaugurating the plant, Chief Minister Siddaramaiah inspected the steps taken to clean Bellandur lake. The action taken by civic authorities will be reviewed by the National Green Tribunal on May 18.
