A bench presided over by Justice U D Salvi ordered the Karnataka State Pollution Control Board (KSPCB) to issue directions to all 99 apartment complexes, which are discharging sewage in the Bellandur and Varthur lakes, to establish modular sewage treatment plants within the available space without posing threat to the structural safety. The state authorities have given time till December 2018 for establishing such plants.
Hearing the suo motu matter arising out of the fire in the Bellandur lake, the tribunal asked the government to address the root cause of problems, leading to pollution of the city lakes.
"Environment justice requires immidiate steps for stopping the continuing pollution of Bellandur lake. This will also stop the growth of microfiles which nurture on these sewages.
