The concerns and methodology suggested is very scientific .However, the utilisation of anaerobic treatment to significantly reduce the loading of Organics in the sewerage system is ignored. Even before Raw Sewage  and Waste water finds connectivity to Sewerage Transport system, use of BIOREACTORS for anaerobic digestion of up to 70% of solids in a resident time of a few days with capturing of biogas or Methane is possible. Lower loading of Organics can also reduce the costs of Sewerage system as lower sized pipes and lesser slopes shall be required. It may reduce the needs for aeration as organic content itself shall be less than 30% of what originates from each household.It is easily possible to design and provide for Bioreactors at the collection points of row houses or each tower and then allow waste water to flow into the sewerage system.
