Alternative arrangements for sewage disposal:
Arrangements for onsite sewage disposal can be made. For example; septic tanks are built in which human excreta are collected. In due course of time, the human excreta get decomposed into compost. Composting pits can be made to dump waste and to make manure from them. Sewage can be collected into biogas plants to produce useful biogas. Chemical toilets can be constructed as they do not require much water for the disposal of human excreta and are environment friendly. Such toilets are ideal for trains.
