Job Description


Consultancy services to undertake detailed engineering designs, contract documents preparation, procurement, and supervision of contractors for the provision of WASH facilities for communities and schools in the Ashanti Region of Ghana.


A. Introduction to WSUP and the Consultancy Assignment

Water & Sanitation for the Urban Poor (WSUP) is a not-for-profit company that helps transform cities to benefit the millions who lack access to water and sanitation. 


We were created in 2005 as a response to the unprecedented urban explosion that has left cities unable to provide basic services, such as access to toilets or drinking water, in low-income communities. We work in seven countries in sub-Saharan Africa and Asia, supported by an office in the UK. Since inception, we have helped over 29 million people access improved water, sanitation, and hygiene services.


In Ghana, WSUP has implemented programs in Kumasi, Sunyani, Accra, and Tamale, as well as multiple adjacent peri-urban areas. For more information on WSUP's vision and approach, see


Sustainability remains a challenge for water supply systems and sanitation service facilities in Ghana particularly in peri-urban, small towns, and schools resulting in the non-functionality of most of the existing facilities in schools and communities and others needing repairs. WSUP, with support from its partners, is implementing a project, entitled Improved WASH services in communities and schools in the Ashanti region. The overall objective is to provide safe water supply, community sanitation, and school WASH facilities in three (3) selected low-income communities in the Ashanti region, and to strengthen the capacity of mandated institutions to support continued WASH service delivery in schools with effective community and school management model to ensure sustainable service delivery.


Building on the successful provision of improved water and sanitation services to communities and schools in Abofour, Asankare, Kyekyebiase, and Serebourso all in the Ashanti Region, this intervention will extend work to a further three locations, improving water supply to communities and WASH in schools while supporting all six communities to improve access to onsite household toilets.


This will be done through the construction of new community water systems and school WASH facilities run under financially sustainable management models. We intend to build community resilience through engagement and hygiene campaigns and training of community and school facility managers. The project seeks to develop community systems building of capacity for comprehensive WASH delivery and engage District and Regional stakeholders for effective monitoring and coordination of WASH facilities.


The project will provide a safe water supply to the community residents of Abofour, and improve WASH facilities in basic schools in the communities of Bomfa, Ofoase, and Abofour. Across these three locations and a further three communities: Asankare, Kyekyebiase, and Serebourso, WSUP will support the development of community supply chains to improve access to household sanitation.


There is therefore the need to conduct feasibility and baseline studies in the proposed communities, and further undertake robust engineering designs, procurement of a contractor(s), and supervision of works to ensure the effectiveness and sustainability of water service delivery and school WASH infrastructure in each community.


The service of a consultant and/or agency is therefore required to undertake detailed designs of appropriate water supply schemes and school WASH facilities, considering the needs and limitations of the communities, in each of the proposed beneficiary communities, prepare tenders and contract documents, facilitate the procurement process leading to selection of contractors and supervise the selected contractors to deliver the proposed water supply systems and school WASH facilities and train facility managers within the project timelines.


The Consultant will also facilitate the establishment and reorganization of community management committees in Abofour, Bomfa, and Ofoase to ensure representation and activate the already established Community Management Committees in Serebuoso, Asankare, and Kyekyebiase. District environmental health officers will be mobilized to select and train local artisans to promote, sell, and oversee the construction of toilets in households.

Provision of 1no. school WASH facility and household toilet promotion and construction.


Asante Akyem South Municipal Assembly – Juaso

Provision of 2no. school WASH facilities and household toilet promotion and construction.


Asante Akyem Central Municipal Assembly – Konongo

Household toilet promotion and construction.


Asante Akyem South Municipal Assembly – Juaso

B. Objective of the Consultancy

The objective of the assignment is to design water supply systems and school WASH facilities in accordance with Community Water and Sanitation Agency (CWSA) standards, Metropolitan, Municipal and District Assemblies (MMDAs), and Ghana Education Service (GES) guidelines and regulations, and facilitate the selection and training of community-based household toilet construction artisans towards ensuring sustainable and affordable water supply system, school WASH facilities and household toilets to the beneficiary communities and schools.


The overall objective of the project is to improve access to safe and affordable water supply services to a large portion of Abofour residents, a growing community with a current population of approximately 16,000. A feasibility and baseline studies will be conducted in the 3 new communities by the Consultant. Using the data from these assessments, a location-specific hydrogeological study will be conducted to ascertain the groundwater availability in Abofour to design and construct a comprehensive water system that is suitable for the population. The proposed project infrastructure in Abofour will ensure that approximately 55% of the population will be able to access water, using the standard of being no more than 500m from the household. In addition to this, the proposed project will explore solar technology to be installed for the system. A hybrid water pump will be used with the capacity to utilize the solar system as the primary energy source but with the ability to switch to the national grid when necessary. The project will provide four standpipes fed by a gravity system from an elevated tank, with multiple shared taps for the community and 100 household connections and/or local institutions example health care facilities. The design and size of the water system should ensure that the system can easily be expanded with a further distribution pipeline, additional taps, and household connections this means that a high-yielding water source is required in order to accommodate these potential future modifications.


Access to safe school WASH facilities will involve the design and construction of five school WASH blocks for basic schools in Ofoase (two blocks), Bomfa (one block), and Abofour (two blocks). These will be a minimum of 14-seater toilets including handwashing facilities, separate chambers for boys/girls/teachers, changing rooms and showers for girls during menstruation, and a mechanized borehole to ensure continuous water availability for the facilities at the schools.


The service of a consultant is therefore required to conduct feasibility studies and undertake detailed designs of appropriate water supply schemes and school WASH blocks, considering the needs and limitations of the communities, in each of the proposed beneficiary communities, prepare tenders and contract documents, facilitate the procurement process leading to the selection of contractors, supervise the selected contractors to deliver the proposed water supply systems and school WASH blocks within the project timelines and to acceptable quality standards and facilitate the selection and training of community-based artisans for promotion and construction of household toilets.
