Barriers to achieving and sustaining access to water, sanitation, hygiene, waste management (collectively, “WASH”) in healthcare facilities include a supportive policy environment and adequate funding. While guidelines exist for assessing needs and making initial infrastructure improvements, there is little guidance on how to develop budgets and policies to sustain WASH services in the long-term. This research was conducted on costing and advocacy activities in Thakurbaba municipality, Nepal, with the aim of developing a budget and operations and maintenance policy for WASH in healthcare facilities in partnership with the municipal government. The objectives for this study are to (1) describe the process and methods used for costing and advocacy, (2) report the costs to achieve and maintain basic WASH services in the eight healthcare facilities of Thakurbaba municipality, and (3) report the outcomes of advocacy activities and policy development.
