The Development Process Study and Groundwater Supply Management System, Lad Yai Sub-District, Mueang Samut Songkhram, Samut Songkhram

Abstract

Lat Yai Sub-District, Mueang Samut Songkhram, Samut Songkhram is an area experiencing water shortage, water surface area cannot be stored sufficiently for consumption–consumption. Therefore, groundwater is another important source of water. The purpose of this study was to compare the designs of groundwater supply systems of the Department of Groundwater Resources in Lat Yai Sub-District, Mueang Samut Songkhram, Samut Songkhram. And design the groundwater supply system to have standards. Using the EPANET 2.0 math model to compare the model of groundwater supply system is the groundwater development project for small-scale consumption. The main components are an groundwater well, a tall tank tower with a capacity of 80 cu.m., and a water distribution pipe. The project model will be distributed according to the dwelling or water user group with water demand in each area in the sub-district. Compared to large-scale groundwater development projects for consumption, whose main components are groundwater wells, high tank tower with a capacity of 300 cu.m., together with a steel water tank with a capacity of 2,000 cu.m. and water distribution pipes. The project model will have a location at only one suitable point and distribute water to all areas in the sub-district. From the study results, it was found that large-scale groundwater development projects for consumption-consumables can distribute water to all areas in the sub-district with more cost-effectiveness than small projects. Calculated from the price of drilling a well project construction value water distribution system design and the rate of expenses for maintaining the project throughout its lifetime. However, the above values are only comparable results in Lad Yai sub-district. This may change according to the area conditions and the water consumption demand of different populations.
