| Abstract | The study has been initiated to develop a sound methodology for fixing optimal scale of a water supply system in a developing country, with a particular reference to the existing conditions prevalent in
Thailand. Optimal design period being directly responsible for bringing down the present value cost of construction, is a function of economy of scale factor and work has been done to determine this parameter for three different types of treatment plants and in each case, the optimal design
period was evaluated. The optimal design period as evaluated from the model was found to be 11 years, 17 years and 21 years for each of the
plant employing chlorination only, slow sand filtration and rapid sand filtration.
Capital and operation and maintenance cost models were developed for three types of treatment systems which it is hoped, will facilitate the
planning and designing operations of water supply system. It was found that
the capital cost required to construct a treatment plant employing chlorination only, for a design population of 1000, amounted to $11,800 and the
cost ·increment: for the same capacity system employing slow sand filtration, rapid sand filtration system was found to be more by 95% and 128% than the
cost of chlorination only. Similarly, for operation and maintenance cost of a plant having a capacity of 0.1 mg d, the probable cost for three types
of treatment plants i .e. slow sand filtration, rapid sand filtration and chlorination only was $58, $48 and $33 per million gallons of treated water.
And finally, selection criteria based on imputed water supply benefits has been developed to cope up with the usual limited budgetary condition, as is often found in the administrative structure of a developing country. |
