Twin-Pit system:
  • Under the twin-pit system, two pits are dug with honeycombed walls and earthen floors which allow liquid to percolate into the surrounding soil.
  • When one pit is filled and closed off, waste flow is transferred to the second pit, allowing waste in the first pit to be converted into manure after a year or two.
  • The twin pit has been promoted by the Ministry of Drinking Water and Sanitation as well as the World Health Organisation as an in-situ sanitation system.
  • This system claims to bypass thorny issues such as caste purity, as owners will be dealing with manure, not excreta.
Data:
  • National Annual Rural Sanitation Survey 2018-19, shows that just 26.6% of rural households use the recommended twin-pit system to dispose of excreta from their toilets.
  • Septic tanks are the most popular option, with 28% of toilets connected to a septic tank with a soak pit and 6% to a tank without a soak pit.
  • Uttar Pradesh tops the list with 64% of toilets with twin pits.
  • Uttar Pradesh had made the technology mandatory for anyone who wanted to avail the government’s ₹12,000 subsidy to build toilets.
