Solution

i. During large public gatherings like Pandharpur vari mobile toilets are deployed by the Government. These mobile toilets are an example of ecological sanitation.

ii. This is a practical, efficient, and cost-effective solution for human waste disposal.

iii. In order to conserve water and prevent the creation of sewage, ecological sanitation (ecosan) is a sustainable system for handling human excreta using dry composting toilets.

iv. Organic waste disposal:

Ecological sanitation (Ecosan) is an approach to sanitation provision which safely reuses excreta in agriculture. This reduces the need for chemical fertilizers.

Ecosan toilet is a closed system that does not need water. It is an alternative to leach pit toilets in a place where water is scarce or where there is a risk of groundwater contamination. It is based on the principle of recovery and recycling of nutrients from excreta to create a valuable resource for agriculture. When the pit of an ecosan toilet fills up, it is closed and sealed.
After about 8-9 months, the faeces are completely composted to organic manure.
