SFD Lite Report - Tarakeshwor Municipality, Nepal

Tarakeshwor Municipality is located in Kathmandu district in Province no. 3 of Nepal. The total population of the municipality is 81,443 people residing on 20,133 households. Most people are dependent on public water supply. Households without access to public water supply rely on well and tap water. 38% of population are dependent on sewer system, followed by user interface directly connected to open drain, lined tanks with impermeable walls and open bottom, lined pits with semi-permeable walls and open bottom with no outlet or overflow and a small percentage of people use fully lined tanks. The emptying frequency widely varies as the containments are not built in a standard way. Both manual (59%) and mechanical emptying (41%) were prevalent. The mechanically emptied faecal sludge is transported with a desludging vehicle, a tank equipped with movable centrifugal pump on a truck. The municipality lacks treatment facilities for treating wastewater and faecal sludge. All the wastewater, supernatant and emptied faecal sludge get finally discharged in Sangle and Mahadev Rivers.
