Approval Date: June 2022

As a part of developing this guideline, the existing O&M situation of water supply and sanitation technologies implemented by both the Government and other sector partners was studied to capture the existing challenges for O&M at the field level in different hydro-geographical settings. Different good practices on the O&M model by sector partners were reviewed and assessed. Recommendations of the users and different sector partners were documented about the sustainable solution of O&M through online/face-to-face Key Informant Interview (KII) and Focus Group Discussion (FGD). Several sample spot visits were made to WSS facilities at different settings such as Barind, Haor, Hill Tracks, Coastal belts, arsenic-prone areas, urban slums, schools, and community health care facilities.
