There were some houses in Anu’s village which had no toilets and were too far to connect with a sewage system. So, government officials granted money under the Swachch Bharat Mission to construct eco-friendly, low water usage toilets that do not need a sewage system. Which of the following types of toilets could be constructed at a minimum cost?
Vermicompost toilet
A vermicompost toilet is similar to a composting pit where the composting of human excrement is done by earthworms. Such toilets are cheap and hygienic to build. They also provide good supply vermi-cakes which can be used as manure. These toilets also require low water use.
