➣ Three main types of containment systems found in Bodhgaya are:
1. Lined pit with semi-permeable walls and an open bottom (honeycomb structure) - 13% of the population is attributed to be dependent on such a system
2. Fully lined tank connected to an open drain is attributed to 25% population
3. Septic tank connected to an open drain or storm sewer is attributed to 24% population.
4. 38% population is still practicing open defecation
