29. Decision Tree Sewerage System Is Simp. Sew. Cheaper than Onsite Sanitation? YES Is minm. 40LPD per Cap water available? YES Do most houses have Safe Septic tanks? NO Simplified Sewerage Can balance houses have septic tanks? Keeping safe distances from specified Structures? YES YES Settled (Small Bore) Sewerage NO NO Is Water Supply Augmentation Feasable? YES NO Go For onsite San.
30. Our Dream Treatment of Rural Waste Energy Neutral System No Random Methane Emission Carbon Neutral System Maximum wastewater Reuse/Recharge Rainwater Filtration & HARVEST Recovery of Energy via Biomethanation of Solids and Liquids Fertilizer & Energy from Sludge Self Sustaining Process No Nitrous Oxide Emission
31. Current Scenario fertilizer production from finite resources food Mixing of flow streams, misuse of drinking water for transport 90% untreated waste disposal in water bodies sewage sludge Overexploitation of groundwater Courtesy gtz GHG Emissions N2O CH4 CO2
32. Dream Scenario Restoring Soil Fertility Treatment / Hygienization / Energy Recovery Water Reuse NO Waste Disposal in Water Bodies Rainwater Harvesting food Organic Waste Faeces Urine Greywater Energy and Fertilizer Recovery through Biomethanation Agricultural Use Courtesy gtz Emission Reduction GHG Emissions N2O CH4 CO2
44. The Systems Now in Use @ VLIF Anaeroobic Filter Planted Filter Primary/ Secondary treatment Anaerobic Filter (Attachable to BR. Anaerobic Baffled Reactor Horizontal Planted Filter/ Root Zone/ Wetland
45. Combined into One Unit The Settling tank, Baffled upflow reactor and Anaerobic Filter can be plugged together, The whole system is underground and has a total Hydraulic Residence time of 8 t0 14 hrs. like the UASB reactor
46. The whole System can fit in any place and is always underground Small surfaces become available for treatment (sidewalks, private yards, parking lots, alleys, parks, etc.) In a Street
52. Locations for Final treatment next to existing ponds Location for Storage of Filtered Rainwater Runoff, to form a lake
53. Original Site for centralized treatment with pump house etc Nullah Water Course Four Decentralized sites chosen for Primary Treatment, 2 along Nullah & 2 along water course
54. Baffled Reactor 1, along Nullah Baffled Reactor 2, along Nullah Baffled Reactor 3 Baffled Reactor 4 Natural Wetland to be modified with Vetiver for sec.& Ter trtmnt. Vetiver plantation for final Nutrient uptake, in water course Narur Contd.
55. Effluent is currently discharging here into the Bein It is proposed to pump the raw Sewage across the Bein for treatment here
56. Section of the Bein Treatment along the acquired area long the Bein
