electricity and
dyes in inlets

SEWAGE MINING

15. Herohalli, Magadi Road

16. Puttenahalli
● 13 acres
● 5-8 MLD from
private STP
● Provision for
WETLAND
● New Idea/Hope

treatment
● Water is first
used in the park,
excess into the
lake

19. Lalbagh Lake

20. Kelagina Ambalipura
● 7 acre lake
● Surrounded by 4
apartments
● Treated water
from STP used for
drip irrigation

21. Kelagina Ambalipura

22. Phytorid

23. Other Lakes/STPs to be seen
● Doraikere
● Dasarahalli
● Malathahalli

24. The reuse of treated waste-
water
• With a constructed wetland further
polishing occurs
• Wetlands become bio-diversity spots
• Eco-system service functions of water
fulfilled
• Groundwater recharge allowed
• Fisheries possible

25. KEY Learnings from
Rejuvenated lakes and STPs
● Diversion of sewage: Not necessarily a solution
● Despite STP an Alternate sewage diversion
channel is also required
● Water Inflows to a lake through an STP followed
by a well sized WETLAND seems to enable the
sustainability of the lake.
● Redirection of treated waste water from private
and public STPs is worth exploring
