Save Doddanekkundi lake

Save Doddanekkundi lake

1. Zero volume of sewage discharge into the lake and remodelling of Rajukaulaves.
2. Development of Sewage Treatment Plant before discharging water into the Doddanekkundi lake

Why is this important?

While all the focus has been on the highly polluted Bellandur and Varthur lakes, little attention is being paid to what is happening upstream of these lakes that make up for the chain of water bodies leading to Bellandur lake. With untreated sewage flowing unabatedly into Kaggadasapura lake, and eventually into Doddanekundi lake, the likelihood of Varthur and Bellandur lakes getting a chance at rejuvenation is not looking bright.

In 2015, the Bruhat Bengaluru Mahanagara Palike (BBMP) undertook a ₹10-crore project for rejuvenation of Doddanekundi lake, which included dredging, building bunds, and fencing the lake area to prevent encroachment. Now, the lake has a large open drain flowing into it, and garbage-filled storm-water drains around it, which end up contributing nothing but the waste into the lake[1] [2].

Doddanekkundi lake was once a much bigger ecosystem with huge catchment area, it supported a lot of flora and fauna, rare migratory and residential birds visited and lived in the lake.

Various government agencies such as the Bangalore Development Authority (BDA) and Bruhat Bengaluru Mahanagara Palike (BBMP) have spent crores of rupees on the beautification and rejuvenation of various lakes across the city. However, owing to lack of planning and standard procedure and confusion over ownership and maintenance responsibilities, rejuvenated lakes are either getting encroached or polluted again.

The inflow of sewage directly or through storm-water drains (SWD) continues in many of the rejuvenated lakes, and most of them do not have sewage treatment plants (STP). In addition, rejuvenated lakes continue to remain dry because of poor monsoon.

Sewage enters doddanekkundi lake (a 130 odd acre lake) every year after the government spent crores in 2014-15 and worked on its "revival", drain inlets are open every rainy season, forcing the continuous flow of sewage into the lake for 2-3 months of the year.

This is due to the outdated design of the Rajukaluves connected to the lake, the drains flood the surrounding areas which cause people to breach the inlets into the lake, we can't blame anybody here, but it is a practical problem and a very much solvable problem if the authorities put enough effort into considering all possible scenarios and honestly execute a well-studied model.

Our demands:
1)Zero volume of sewage discharge into the lake and remodelling of the Rajukaluves, we don't want our lake to be a large breeding ground for mosquitoes and other pathogens.

2) On long term demand include wetland treatment or development of sewage treatment plants (STP) to be funded and executed. To avoid situations where sewage inevitably has to enter lake during rains, we want to make sure that the sewage entering is treated, so as to protect most of the lake from sewage contamination.

3) We want BBMP to prevent garbage dumping and encroachment around and in the lake, deploy permanent security/cleaning staff for maintenance and protection of the lake if need be.

Benefits of executing our demands:

1) A clean and safe environment means all citizens feel good and healthy.

2) Zero sewage discharge would ensure shallow and clean waters when it rains and flocks of birds would once again visit and maybe even breed like in 2014-15 when no sewage entered[3].

3) The water table in the Doddanekkundi, Kagdaspura, Vignannagar, Vibuthipura, Gururaja layout, Basvanagar, Virla layout and other areas around the lake would improve.

4) Would set a model to improve the condition of other lakes in Bangalore.
