Question

Write two alternative methods of sewage disposal.

Answer 1

Two alternative methods of sewage disposal are :

1.Biogas Plants: Biogas plants are usually common in villages in which the human and animal wastes are passed into the biogas plants through covered drains. Microorganisms present in the wastes break down the waste and produce biogas which is used in the generation of electricity.

2. Vermi-composting toilets: This is a safe, hygienic, water saving, innovative design in which earthworms are used to convert human wastes into compost.
