Modification of Group Housing Project, Village Babupur, Sector -108, Gurgaon, Haryana CONCEPTUAL PLAN Sullage Generation & Treatment It is expected that the project after modification will generate approx. 1213 KLD of sullage. The sullage will be treated in 3 onsite STPs of 600 KLD, 720 KLD and 230 KLD capacity that will generate 1092 KLD of treated water from STP which will be reused for flushing, horticulture. SEWAGE TREATMENT TECHNOLOGY EXTENDED AERATION TECHNOLOGY Sewerage System An external sewage network shall collect the sewage from all units, and flow by gravity to the proposed sewage treatment plant. Following are the benefits of providing Sewage Treatment Plant: Reduced net daily water requirements, source for Horticultural purposes by utilization of the treated sullage. Reduced dependence on the public utilities for water supply and sewerage systems. Sludge generated from the Sewage Treatment Plant shall be rich in organic content and an excellent fertilizer for horticultural purpose. Treatment Technology Treatment technology is based on the Extended Aeration Technology. Raw sewage will be collected under gravity into the sump after allowing to pass through the bar screen. The bar screen, by removing coarse solids from the sewage help in protecting the raw sewage pump.
