27 lakes in Bengaluru will be taken up by BBMP for restoration. The project will be taken up on the ‘comprehensive development” plan.
Bengaluru, also known as the ‘Garden city’ of India, was dotted with numerous lakes. Kempe Gowda, the founder of Bengaluru and his successors built more than hundreds of lakes and tanks in the city which are now slowly fading out from the heart of the city due to rapid urbanization and discharge of effluents in the water bodies.
Status of lakes in Bengaluru :
- Eutrophication of lakes because of nutrient input
- Inflow of sewage to lakes
- Shrinkage of water body
- Solid waste dumping in the periphery of lakes
- Encroachment of lake and urbanization in catchment area
- Reduced storm water flow to lake body due to interception in catchment area and deforestation
- Shoreline erosion
- Weed growth
Lakes in Bengaluru :
Lakes in Bengaluru are numerous, and there are no rivers close by. Most lakes in the Bengaluru region were constructed in the sixteenth century by damming the natural valley systems by constructing bunds.
The effect of urbanization has taken some heavy toll on the Beautiful lakes in Bengaluru. The lakes in Bengaluru have been largely encroached for urban infrastructure and as result, in the heart of the city only 17 good lakes exist as against 51 healthy lakes in 1985.
Urban development has caused 19 lakes getting converted to bus stands, Golf courses, playgrounds and residential colonies, and few tanks were breached under the malaria eradication program.
BBMP to breathe life into 27 lakes :
The BBMP will be fixing inlet and outlets, creating wetlands, island sand repairing the existing bunds. The work includes desilting to increase the holding of water capacity.
The State government has sanctioned Rs.348 crore for the rejuvenation project. The BBMP proposed to include public toilets, fencing, children’s park. boating and other small parks.
27 lakes – Zone wise rejuvenation :
The civic body is planning to rejuvenate lakes zone wise. They zones where lake are identified are :
Mahadevapura zone – 9 lakes
Bommanahalli zone – 13 lakes
Rajarajeshwarinagar Zone – 2 lakes
Dasarahalli Zone – one lake
Yelahanka Zone – one lake
Bengaluru South Zone – one lake
According to a BBMP official the work will be done on stages. They are going to do entry level revival with respect to storm-water drains. Diversion channels will be revived so that the sewage water is prevented from entering the water bodies.
Tenders have been called for the project and the work will be starting very soon.

Co-operation with other departments :
The BBMP Lakes department should coordinate with storm water drain department and BWSSB to face any emerging issues to avoid future floods, back-flow pollution etc.
Deep desilting is also needed to resume the original depth of the lake. Ecologists, environmentalists and hydro-geologists are to be involved.
Private adoption of lakes :
Five firms have signed an agreement with the Karnataka State government to adopt lakes in and around the Bengaluru city a few months back.
India Inc. came forward to adopt 6 lakes in Bengaluru for rejuvenation. The 6 lakes adopted are Kenchenahalli lake by Meritor CVC India Ltd., Doddathogur lake by Elcia, Shikaripalya by Wipro, Yarandahalli lake and Kammasandra Lake by Biocon and Maragondanahalli lake by Timken India Ltd.
Lakes will not breach this monsoon :
For those living by the lakeside in Bengaluru, the monsoon is always a worry. The risk of flooding or even a breach cannot be ruled out. Surprisingly this year, the BBMP has said no lake is expected to breach or overflow.
Last year, the Bruhat Bengaluru Mahanagara Palike (BBMP) had identified some lakes ahead of the monsoon that could pose danger to the residents.
The lakes included Gubbalala Lake in Uttarahalli, Begur Lake, Vasanthapura Lake, Doddakallasandra Lake in Vasanthapura and others. These lakes reportedly had breaches due to weak embankments or had no embankment at all.
BBMP officials did not rule out lakes overflowing this monsoon if the rainfall is too heavy.
