Bellandur tank is part of the Bellandur drainage system that drains the southern and the Southeastern parts of the city. The tank is a receptor from three chains of tanks. One chain, originates in the north, from Jayamahal, covers the eastern portion and has been referred to as the eastern stream. Another chain originates from the central part of the city, from around the K.R.Market area and covers the central portion and is called the central stream. The other chain, that reaches the tank is through the south-western region and is called the western stream. The catchment area of Bellandur tank is an area of about 148 sq kms. Water from this tank flows further east to the Varthur tank, from where it flows down the plateau and eventually into the Pinakani river basin.
Bellandur gram panchayat approached the High court (HC) to prevent the pollution of the lake.
Panchayat President Jagannath Reddy and environmental activist Ramamurthy, supported by villagers initiated court proceedings to get the Bangalore Water Supply and Sewerage Board (BWSSB) to clean up the tank and prevent untreated sewage from flowing into it. The sewage treatment plant at the inflow of the lake was upgraded as a result.
Fishermen groups from Yemlur, Kempapura and nearby places petitioned against the chief minister as the polluted lake affected the fish population. The Fisheries department introduces baby fish into lake for increasing their numbers, which do not survive due to heavy pollution.
The catchment area of the lake was brought under the notification by the Bangalore Development Authority (BDA) to convert it to be a part of the ring road linking ITPL and Electronic City
The Lake was declared unfit for 1997 National Games due to high rate of siltation.
After the 1997 notification on outer ring road, a farmer’s association from Bellandur and surrounding areas protested against the land acquisition by BDA. The Raitha Horata Samiti, on of the activists, was partially successful in getting BDA to alter their route plan, retaining some of the notified land in the process.
The High Court ordered immediate measures to supply potable water to residents in Bellandur and proper treatment of the sewage in the STP. Following the authorities’ lack of compliance to the HC directives, another petition on contempt of court was filed. It is still pending before the Lok Adalat.
Resident welfare groups in Koramangala demanded to prevent sewage mixing with the storm water drain flowing into the Lake. The state unilaterally decided to privatize some of the lakes and tanks around Bangalore.
The Lake Development Authority (LDA), was set up in 2002 to look after the lakes of Bangalore
According to the Lake Development Authority, Bangalore Water Supply and Sewerage Board (BWSSB) kept throwing the untreated sewage into the lake as the Koramangala and Challaghatta valley sewage treatment plant has a capacity to treat just 20 million litres per day (MLD) while the inflow into the valley is 384 MLD. This resulted in Rs 1.82 crore already spent on clean-up operations go waste.
This realization dawned on the Lake Development Authority only in 2005 and the project itself was abandoned in November.
According to the Karnataka Pollution Control the contractors Bangalore Mahanagar Palike continued to dump garbage in the lake.
Environmentalist A.N. Yellappa Reddy urged the Lake Development Authority, Bangalore Water Supply and Sewerage Board, Karnataka State Pollution Control Board and other concerned agencies to clean up the polluted Bellandur Lake. Officials of the BWSSB planned to increase the capacity of STPs by 55 million litres a day (MLD) from 163 MLD.
Ram appealed to the Deputy Commissioner (Urban) of Bangalore district for the same. No response.
The Lake Development Authority-received a nod from the Ministry of Environment and Forests to restore this old lake using bio-remedial techniques at an estimated cost of about Rs 5.5 crores to 7 crores.
Ram made similar complaint to Karnataka Information Commission (KIC). First hearing for the case took place. The Tahsildar was directed to ascertain whether the survey report of Bellandur tank (conducted during September 2006) was made available to Ram.
Second hearing. Case disposed. The drawings of the encroachments on Bellandur were not ready with the Gasholder and hence could not be given Ram. The Commission directed the Tashildar to furnish correct drawings at the earliest.
Second reminder by Ram. No response.
Third reminder by Ram.No response.
KIC sends a show cause notice to the Tashildar, No response although the stipulated time is over.
