Based on the experience in Pune and other cities I can make the following comments.
a) Requirements will be for residential complexes, Promoted and developed township by builders & Municipal Corporation.
b) The projects are specific to the sewage quality and quantity and space available. The treatment units are oxidation ponds, Root zone cleaning system, activated sludge process, trickling filter etc.
c) Rules are regulations are for the treated sewage that can be made available from the office of pollution control board.
Please note the quality & quantity are the deciding factor. The treated sewage can be reused
