Bengaluru: The Karnataka State Pollution Control Board (KSPCB) collected samples of 125 water bodies in the state in April-May period and they all fared miserably in the water quality index table.

In the entire state only seven water bodies, none from the city, were found to have satisfactory Water Quality Index (WQI).  

 

Pilikula Tank in Mangaluru is the only water body in the entire state to be classified under Class A and Vimanabhutikere in Davangere under Class B.

As per the standard set up by the Central Pollution Control Board (CPCB) water bodies are classified from Class A to E. All the city’s water bodies fall either under Class D or E, thereby indicating that not a single lake can be used as a potential source for drinking water.

While the water bodies in the cities continue to get polluted, the BBMP is yet to put up a viable mechanism to let only treated water into the lakes.

The SWD which is supposed to cover 842 km in 2006-2007, but so far only 300 km has been completed. The Palike has told the high court earlier this month that the construction of 192.35 km of the SWD, apart from the desilting of 157 km of the drain, has been completed.

Though BWSSB claims that it has provided 100% underground sewerage to the core areas of the city, but lakes in these areas do not have satisfactory WQI.
