NORTH DELHI MUNICIPAL CORPORATION 90 (WITH CONCESSIONAIRE M/s ANSH BUILDERS PVT LTD) MODIFICATION IN MULTILEVEL CAR PARKING COMPLEX, CONCEPTUAL PLAN CHANDNI CHOWK, NEW DELHI SEWAGE TREATMENT PLANT MBBR TECHNOLOGY An external sewage network shall collect the sewage from all units, and flow by gravity to the sewage treatment plant. Following are the benefits of providing the Sewage Treatment Plant in the present circumstances: The process has long retention time and can absorb shock load situation. Reduced net daily water requirements, source for Flushing and Horticultural purposes by utilization of the treated waste water. Reduced dependence on the public utilities for water supply and sewerage systems. The process produces a well-oxidized sludge in small quantities only, which can be removed and used as manure. a.
