    Optimal production of potable water case study: Agona Swedru - Ghana water company limited (GWCL)
    (2011-06-13) Nyame, Moses
    Water is a constrained natural resource and in many areas of the Planet water shortage is considered to be possibly the most critical issue to be resolved. Water supply chain management and optimization are evolving as the most difficult and urgent problems, since the water demand and availability vary significantly with time. This makes it necessary to reflect upon the long term viability of some of the approaches advocated and their challenges. More specifically, the basic idea of the research is the development and implementation of a beneficial mathematical model using linear programming and the effect level of inputs on the mode in order to optimize the total water value. The collection and analysis of data using optimization techniques from the Kwanyaku Headworks took eight month. The research identified regular power outage leading to high cost of maintenance, electricity cost, chemical cost, capacity of low and high pumps and labour among others as the reasons for the irregular and expensive cost of water treatment to Swedru and its environs. However chemical cost, electricity cost and extra-duty cost (labour) are the major factors influencing water treatment. An estimated cost used in the research revealed a 7.12% less the treatment cost in the same volume of water (746,520m3 ) in the dry season and13.15% less the treatment cost in the same volume of water (787,285.716m3) in the wet season.
