Project Background

DUSIB night shelter at Yamuna Bazaar old bridge (Locally known as Old Lohapul) was inaugurated in 2009. The night shelter was designed to house 50 people in the shelter, while the shelter receives 35 people on an average every day in summers while the number goes upto 80 during winters.

Treatment technology

  • The site is installed with 2 toilets which are connected to a biodigester with a capacity of 2400 litres
  • Treated water from the bio digester is drained to a soakpit
  • The biodigester has four sections and the wastewater from toilets passes through each section
  • Material used to create sections in the biodigester is covered with coir
  • Inoculum is added to the coir on the sectioning material which reduced the solid matter from the wastewater and acts as a filter to the liquid content 
  • Biodigesters are filled with inoculum (bacteria used for digestion of faecal sludge) up to 30% of the biodigester capacity
  • The system does not require any external energy for its operation
  • A gas vent provides passage for the gasses generated during decomposition to move out
  • The biodigesters are lined with coir which increase the surface area for multiplication of the bacteria
  • It has been instructed by DUSIB to the vendors who look after the site that only 2-3 litres of water should be used per person.
