About the Project: Accelerating Municipal WASH Agenda

WSUP is implementing a project dubbed ‘Accelerating Municipal WASH Agenda’ in partnership with the Atwima Nwabiagya Municipal Assembly (ANMA). The project aims to support Atwima Nwabiagya Municipality (ANMA) in achieving universal access to sustainable WASH (Water, Sanitation, and Hygiene) by 2030 by strengthening systems, infrastructure, finance, and community ownership.

The project seeks to increase access to safe water, in two phases by providing support to Ghana Water Limited (GWL), the urban water utility, to extend their distribution service line to peri urban communities of the municipality where access is limited. Water supply will be extended to 2 communities in the municipality where access to water distribution lines of the municipality is feasible. Also, the project will support 3 small towns in the municipality where GWL does not operate. To ensure strong community involvement in water service delivery in the communities, this activity will further include the set up and training of water user associations (WUAs) and community management teams (CMTs). The WUAs and the CMTs will serve as customer platforms to interface with the utility and the Municipality for improved services.

Background Of The Assignment

WSUP, with funding from Anonymous Donor, in collaboration with Atwima Nwabiagya Municipal Assembly (ANMA) and Ghana Water Limited (GWL) is implementing the “Accelerating Municipal WASH Agenda’’ project.
