Water Allocation Analysis with a Cost-effective Analysis of the Economics of Groundwater Development and Large-scale Long-distance Water Delivery to Solve the Problem of Water Shortage, Drought Crisis Si Somdet Subdistrict Si Somdet District Roi Et Provi

Abstract

From the past drought situation, Thailand always have problem of water shortage every year. As a result, many areas have insufficient water not enough for consumption. cannot be used for consumption sufficiently which from the limited amount of surface water need to develop Groundwater from large groundwater sources makes water allocation analysis and economics analysis essential in measuring the investment in water supply of projects addressed by the area taken. to analyze, namely, the area of Si Somdet Subdistrict Si Somdet District Roi Et Province and Nong Fai Subdistrict, Lao Khwan District, Kanchanaburi Province The two areas are different in terms of topography and purpose of using water. by the area of Si Somdet Subdistrict Si Somdet District Roi Et Province There is a long-distance water delivery project. for people to use drinking water - consumption including delivering water to the hospital in this area, water for consumption will be analyzed. Including water sent to hospitals to help people. The amount of water received will be less than the estimate before the project. Due to the intrusion of salt water increases. Including the expansion of the population more At present, it is 3 years after doing the project. Causing the need to analyze the water allocation and the cost-effectiveness of the project again to be applied to nearby areas Nong Fai Subdistrict, Lao Khwan District, Kanchanaburi Province It is a project that has allocated water to the people, both drinking water - consumption. including irrigation water The irrigation water will be analyzed with the WUSMO program and the results will be analyzed for the entire water allocation system with the EPANET program, which will analyze like this in both areas. The expected results from this research study are Water allocation can be utilized appropriately and for maximum benefit. which must be allocated considering both the delivery time and the amount of water so that the water pipeline network can be delivered adequately This study guideline will make known effective and sustainable water allocation and water management for the people. Including the appropriate and sufficient water cost for managing the water distribution system in both areas For the area of Si Somdet Subdistrict Si Somdet District Roi Et Province At the water rate of 19 baht per cubic meter, the B/C value was 1.04 and the EIRR was 6.48 percent. and the area of Nong Fai Subdistrict, Lao Khwan District, Kanchanaburi Province The water tariff at 15 baht per cubic meter will result in a B/C of 1.01 and an EIRR of 6.16%.
