Abstract
The main aim of the study was to estimate the life cycle cost of sustainable water and sanitation service delivery and the quality of service delivered. The life cycle cost analysis involved investment, capital maintenance, operation and maintenance and support costs and were used to assess how project sustainability throughout the facility life will be achieved. The study was conducted on one (1) small town water supply scheme in Kuntanase, three (3) boreholes with hand pump one each in Kuntanase, Abono and Petriensa and three (3) household latrines in Kuntanase. The design life of the WASH facilities was considered to be twenty (20) years. Data was gathered from stakeholders at all levels by means of interviews and administration of questionnaires. The stakeholders included the Community Water and Sanitation Agency (CWSA), District Assembly (DA)/District Water and Sanitation Team (DWST), Water and Sanitation Development Boards (WSDBs), Water and Sanitation (WATSAN) committee members, and Community members. The costs of investment, operation and maintenance, capital maintenance and support costs were estimated and converted to their annual costs based on historical cost data collected during the study period. The quality of WASH service was analyzed using forty (40) questionnaires based on the quantity, characteristics (water quality), reliability and affordability of the water supply facilities. The results showed that the Government of Ghana/Partner Agencies provides the investment cost and some aspect of the support cost leaving out the capital maintenance (replacement) and operation and maintenance "costs. The capital maintenance, operation and maintenance costs are paid by the users of the facilities. Normally the Government of Ghana/Partner Agencies ignores operation and minor maintenance and replacement (capital maintenance) which are often paid by the users but as soon as the users fail to pay for these costs, the system breaks down. The quality of service derived from the house connection is high compared to the communal stand pipe connection. The quality of service of water supply in Abono is relatively low compared to that of Petriensa and Kuntanase though the people are willing to pay more for a better service.
