Selection of Sanitation Technology for Small Towns
M. Tech Project -I (TD 695)
Waste and Sanitation
The current situation of Sanitation sector in India shows that it lagging behind both technology wise and coverage wise. At present different sewage treatment technologies are available to treat waste based on parameters like type of waste, population density, LPCD of water used, type of soil. But there are no proper set of guidelines mentioning the criteria for the use of different technologies. Though CPEEHO has put down a set of guidelines, there are few shortcoming in the technical aspect of planning. In this first part of thesis analysis of the municipal councils in Maharashtra is done on the basis of population and population density. At present, there are mainly two type of sanitation systems which are taken into consideration before designing a sanitation system in India. One is on-site system, generally for rural areas and other is capital intensive conventional sewerage system for big cities. Usually different parameters like population, rainfall, water supply, elevation, soil strata are taken into consideration before selecting a sanitation system to be designed. But this seldom takes place, due to which there is a serious threat to feasibility of sanitation system both technically and financially. The report discusses the present sanitation situation in Maharashtra and comparison of different sanitation technologies based on literature available. Further, while emphasizing the need for alternative to conventional sewerage system, it studies the feasibility of Small Bore Sewerage system for Sangole. A Small-Bore sewer network is analysed for Sangole town of Solapur district of Maharashtra using a SewerGems.
