3. Nature Based STPs
● Phytorid/DEWATS : anaerobic baffle reactor +
planted gravel filter + polishing pond
● SBT : Soil Bio Technology

4. DEWATS AT HOME LEVEL

5. Waste Water Treatment

Water Reuse

20. Phytorid

23. Delhi Jal Board/CSE

24. SBT : Herohalli, Magadi Road
● 25 acres
● 1.5 MLD STP
● Sewage mining
● SBT
● Issues with
electricity and
dyes in inlets

27. REUSE FOR FLUSHING/GARDENING

28. REUSE FOR
CONSTRUCTION

29. DISCHARGE INTO LAKES

30. Jakkur Lake
● 10 MLD design
● 8.45 MLD inflow
from Yelahanka
and Jakkur
● UASB, EAR
● WETLAND
● STP open for
viewing

31. Design Parameters
The plant is designed for the following
influent characteristics of wastewater.
pH 7.06 – 8.1
Total Solids 782-1352 mg/l
TSS 320-672 mg/l
BOD5, 20°C 290-369 mg/l
COD 465-973 mg/l
Chlorides (as Cl) 74-151 mg/l
Sulphates (as SO4) 11-41 mg/l

32. Design Parameters
The plant is designed for the following
characteristics of treated water.
BOD5 ≤ 20 mg/l
Suspended solids ≤ 30 mg/l
pH 5.5 – 9
Oil & Grease ≤ 10 mg/l
Residual Chlorine ≤ 1 mg/l
Colour & Odour See Note
Iron(as Fe) 3 mg/L
Nitrate Nitrogen 10 mg/L
Note: all efforts are to be made to remove
colour and odour as far as practicable

34. Treatment Plant and Jakkur Lake

35. Treated Wastewater entering the wet
Land System of Jakkur Lake

36. Nature as further treatment

37. Lake ecosystem

38. Fisheries

39. Sludge as Compost

40. Groundwater

42. Community – Jala Poshan

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

44. Puttenahalli

46. Floating WETLAND

50. 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

51. IRRIGATION IN COMMON
AREAS
LOWER AMBALIPURA

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

53. Kelagina Ambalipura

54. 100% REUSE - TZED

55. ● 95 flats and villas
● Waste Water treated
to drinking water
standards – and
used for all purposes
● ASP + slow sand
filter + RO
● 60KLD STP, 40KLD
reused
● 1,00,000/- per month
for running of STP
● FIRST and ONLY in
INDIA

56. Challenges and Way Forward
● ZLD doable ? -
● can excess treated waste water be used for
discharge into lakes, shallow recharge
● If yes, what protocols for monitoring
● Community monitoring/responsibility –
including fisherman, grass cutters
● Low costs Sensors/meters to check for
treated water quality at real time
● Maintenance Costs and Effort/Skill
