22. The following are the issues which had slowed down the progress
of lake restoration works.
• All the lakes are transferred from BBMP / Forest Department to BDA
for further development / maintenance, wherein the majority of the
lakes are encroached, polluted with sewage and garbage dumping.
• Any lake restoration project has to be started with revenue survey of
the lake area, identification of encroachment, demarcation of
encroachment and finally eviction of encroachment which has to be
done by the revenue department, since the proprietary of all the lakes
vests with the revenue department.
•The clearance of encroachment on the lake areas is one of the serious
issues which has slowed down the progress of lake works. In 64 cases the
certification of encroachment, issue of eviction orders are pending which
has to be taken up on priority.
23. • 81 Lakes under BDA control are affected by huge sewage flows, which has to be
connected from the source to the main trunk sewer lines through a conduit which
has to be taken up by BWSSB on priority.
• Since the majority of the lakes in the core areas of the city are encroached, which has
huge no of habitants, wherein rehabilitation of such encroachers has to be taken up on
priority. As a rough estimate 57 lakes contains 2311 No’s of un-authorized habitants
which needs to be rehabilitated. This issue is to be taken up on top priority by the
Urban Deputy Commissioner and The Commissioner Slum Board.
• In majority of the lakes, the Rajakaluves connecting lake to lake to transport the
surplus water are non existant which has led to flooding, loss of property etc. So these
Rajakaluves has to be demarcated on ground, encroachments to be removed and an
earthen section of the Rajakaluve has to be provided for a free flow .
• Lack of adequate financial resources .
• Lack of proper maintenance mechanism.
• Lack of adequate man power .
23
24. There should be a more rigorous approach from the revenue
authorities in tackling encroachments and related issues.
Strict penal actions from the enforcing authorities in tackling
encroachments, dumping of garbage, Entry of sewage into the lakes.
There should be an integrated sewage network system for the entire
Bangalore Metropolitan area, to be addressed by BWSSB on top
priority.
The Rehabilitation of the un-authorized habitants on the lake areas
has to be taken up on priority by the Slum Development Board and
the Revenue Authorities.
The existing lake development authority should be made as a single
nodal agency who can execute, enforce, monitor, maintain all urban
lakes.
The existing Lake Development Authority should be strengthened
with adequate man power.
A proper funding mechanism should be developed to provide
adequate funds for execution and maintenance of lake systems.
