Expert Answer
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.
