Feasibility study, preparation of a sewerage and wastewater disposal programme to the year 2003 and preliminary design of the first phase up to 1993. Present Population 6 million expected to rise to about 11 million within 15 years.
The study of the whole urban area of Karachi involved the identification of sewage flows arising from both domestic and industrial sources during the period from the present to the year 2003. With the objective of improving health standards and sanitation practice, a major target is to improve waste collection systems such that each dwelling unit can be served by 2003. The collected wastewater may form a reusable resource if satisfactory markets can be developed for treated effluent, sludge and methane gas recovered from the sludge. The Study is to identify the most feasible collection and treatment system for each collection zone.
Large parts of Karachi are occupied by Katchi Abadi or upland developments where appropriate forms for sanitation have to be established within socioeconomic constraints. Some sections of the community are already serving on this basis, required further evaluation and identification of improvements.
It was a master plan of Karachi, related to sewerage and wastewater disposal. It involves a feasibility study of the sewerage system with proper methods of disposal too. Prepared sewerage and wastewater disposal programme for the next fifteen to twenty years, with the objective of improving health standards and sanitation practice, a major target is to improve waste collection system and discuss possibilities to reuse this collected waste in a satisfactory method.
