|The treatment facility receives domestic sewage from the two common toilets that caters to one of the buildings of a residential housing colony. The hosing colony is a low income group settlement. The facility at the site has been effective in improving living conditions and sanitation condition in the neighborhood.
|The domestic sewage generated in the two common toilets of one of the buildings first enters into a two chambered settler. The partially treated sewage from the settler then undergoes secondary anaerobic treatment through Anaerobic Baffled Reactors (ABR). The 9 chambered ABR in addition to 4 chambers of filters offer anaerobic treatment through its multiple chambers. The treated sewage is then passed through horizontal gravel filters bed planted with Canna indica. Final treatment is done through polishing ponds that has been innovatively designed with gravity fed fountains that adds to the aesthetics.
|Visually clear water and no odor around the area.
