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. WSUP’s vision, in line with the Sustainable Development Goals (SDGs), is of a world in which all urban dwellers, including the poorest, enjoy affordable, high-quality water and sanitation services. This will generate massive gains in human well-being, in national economic growth and in global environmental sustainability. WSUP has a strategic portfolio of six focus countries in Africa and South Asia (Bangladesh, Ghana, Kenya, Madagascar, Mozambique, Zambia), where it works in close partnership with local service providers and national government. WSUP also works globally through its consultancy arm WSUP Advisory.Within its six focus countries and globally, WSUP works towards its vision through activities in five Strategic Areas: 1) delivering services and testing models; 2) developing capacity in the public and private sectors; 3) influencing and providing technical assistance; 4) mobilising resources for the WASH sector; and 5) carrying out research and producing evidence. As illustrated in the Theory of Change below, all of WSUP’s activities are focused towards the end goal of sector functionality, on the view that sustainable change will not be achieved by donor-funded construction of “taps and toilets”, but rather by coordinated efforts to build functional city-level and national systems for urban WASH services delivery. WSUP believes that the development of such systems depends fundamentally on two things: 1) the transformative power of markets and innovation, and 2) deep political commitment and institutional change. WSUP works to drive change in both spheres.For more information about WSUP's vision and approach, see www.wsup.com.
TERMS OF REFERENCE PROVISION OF CONSULTANCY SERVICES FOR DESIGN AND CONSTRUCTIONSUPERVISION OF PUBLIC TOILET BLOCKS AND SCHOOL TOILET FACILITIES FOR SMALL TOWNS IN ASHANTI REGION Background for the consultancySustainability remains a challenge for sanitation service delivery in small towns in Ghana resulting in non-functionality and poor service delivery of many of the public and school toilet blocks as a result of poor operation and management practices and facility design challenges.A feasibility study which was undertaken for a project to catalyse systemic change through the provision of sustainable water services in small towns of Ashanti region-Ghana revealed that the target beneficiary community for the project are in dire need of improvements in sanitation both at the community and school environments. The communities have inadequate public, school and household toilet facilities; a situation which leads to the practice of open defecation in and around the communities. The few existing community and school toilets are in a poor state exposing users to faecal matter, emitting foul odours and are insecure, especially for women and school children as the available toilets lack privacy and security. The target areas for the proposed intervention are the cocoa-growing communities of Offinso Koforidua and Okaikrom for the construction of public toilet blocks with an estimated total population of 6,979 and basic schools in New Koforidua and Petransa for the construction of school toilet facilities with an estimated total population of 1,538 WSUP, with funding from One Foundation, and in collaboration with respective Metropolitan Municipal District Assemblies (MMDAs) is implementing a project, entitled “Improved WASH for COVID-19 Resilience in Small Towns of Ashanti Region, Ghana”. The project’s objective is to promote sustainable access to safe and improved sanitation and hygiene promotion in 4 small towns of Ashanti region. This will be done through the construction of 2 no. WC public toilet blocks with mechanized water supply system run under financially sustainable management models in two (2) beneficiary communities (Offinso Koforidua and Okaikrom) and construction of 2no.WC school toilet facilities with mechanized water supply system and operates under effective and sustainable facility management plan in two (2) beneficiary community basic schools (Presby basic school in New Koforidua and SDA basic school in Petransa). We intend to systemically evolve the effectiveness of the management models and facility management plans used to deliver hygiene and sanitation services under the project, and to disseminate the learning gained. WSUP has undertaken similar projects in the past and there are designs and reports available from these previous works to There is therefore the need for review of the engineering designs for public toilet blocks and the design of school toilet facilities, support tender process for selection of contractor(s) and supervision of works to ensure the construction and operations of the WC public toilet blocks in the communities and schools The services of a consultant are required to deliver the project objectives. ObjectivesThe overall objective of the project is to build community resilience, in response to COVID-19 pandemic, through improved sanitation and good hygiene practices in targeted small towns of Ashanti Region. We will do this through the construction of user-friendly, safe public toilet blocks and school WASH facilities. This will be accompanied by co-creation of appropriate operations and management models to sustainably run the public and school toilet facilities. The project further aims to reinforce COVID-19 preventive messaging, including the importance of hand washing and social and physical distancing. The specific objectives of the assignment are:Conduct technical feasibility studies, which include technical viability and sustainability, environmental impact and financial feasibility assessment of each proposed facility in each school and community. The studies should take into account the technical and managerial capabilities of the proposed operators and managers particularly in terms of operation and maintenance.
Carry out demand analysis and estimate the future (10 and 25 years) sanitation needs of the proposed beneficiary schools and communities.
Carry out hydrological investigations, including use of existing data as well as field work, to ensure that the selected sanitation sites for construction should provide all year round adequate water yield to the toilet blocks. Rainwater harvesting calculations must also be part of the feasibility study.
