Humla, Mugu and Dolpa are the northern most and remotest district of Karnali Province. The federal structure comprises 4 Palikas, 8 Palikas in Dolpa and 7 Palikas in Humla. All the districts of Karnali province have already declared as Open Defecation Free (ODF) zone while total sanitation promotion has been initiated in few Palikas of aforesaid districts at small scale. Though, there is significant progress on installation and use of basic sanitation (i.e. construction and use of toilets) in these districts, the proper management and hygienic use of toilets, hand washing during critical time, child faces management, institutional WASH management and functionality of water supply schemes still remains a challenge. The ODF sustainability and its further improvement aligning with sustainable development goals (SDG # 6) is comprehended in these area as well. Out of these Palikas, Simkot Rural Municipality, Humla, Chhayanath Rara Municipality, Mugu and Thulibheri Municipality, Dolpa have been selected for this project.
