In rural Tamil Nadu, along with promoting construction of twin pit toilets, people are being educated about the maintenance and socially useful benefits of this toilet model.
- Twin pit toilets are scalable, implementable and cost-effective; and therefore can have a great impact in making rural India open defecation free (ODF). Further at a cost of Rs. 12,000, they are easy to use and make.
- They comprise two pits, each measuring 3.5 feet deep and one metre in diameter; the distance between them being one metre. When twin pit toilets are used, faecal matter will be allowed to pass and settle in one pit only.
