Recently, only 8 of these systems have kept operating at Sub SomboonSub-district, Khoke Pho Chai District, Khon Kaen Province. This survey of village ground watersupply found that the administrative committees and the system operator had never been trainedin water supply management. There was also a lack of system maintenance, lack of daily systemmonitoring, no washing of the filter and tower tank as a designated program, a lack of adjustingthe water pressure, and no chlorination before distribution. The major activities of this researchrequired by the village water supply management committees are to develop the potentialcapacity on water supply management by practical training. Being practically trained wouldprovide knowledge about operation and maintenance of ground water supply management tothe village water supply management committees. After two months of the development training,an improvement in the water supply system was reported as indicated by cleanliness of thewater supply system area, water pump checking, adjusting the water pressure according to thetower tanks’ height, and cleaning filter tanks. However, schedules for regular and continuousperformance still relies on the village water supply management committee’s awareness tomaintain good water quality within the water supply system. Keywords: potential development, village ground water supply system, village watersupply management committee.1. Introduction In Huai Sam Mor Watershed, Khon Kaen Province, there are 15 village groundwater supply systems. 13 of them are located in Khoke Pho Chai District, and other twosystems are in Manchakiri District. In Khoke Pho Chai District, there are two villageground water supply systems in Pho Chai Sub-district and 11 in Sub Somboon Sub-district. However the village ground water supply systems have encountered theproblem of raw water shortage. Currently, only eight systems are in operation, which 245are in Sub Somboon Sub-district, which was the focus for this study. Five village ground water supply systems were constructed based on the designof the Groundwater division, Department of Mineral Resources (Former), and Ministryof Industry. Three systems were constructed based on the design of the Water SupplyDivision, Public Works Department (Former), and Ministry of the Interior. Afterwards,they are to been turned over to be under the responsibility of the village water supplymanagement committees. The Sub Somboon Sub-district Administrative Organizationhas been providing the academic knowledge for system operation and maintenance. There have been several problems regarding the ground water supplymanagement of these eight ground water supply systems. The reason seemed to be theturn over of the village administrative committees, village headman, and maintenancepersonnel. Especially, most of the operators had never undergone training on how tooperate and maintain the ground water supply system. Lack of maintenance has causeda shortening of the life span of the groundwater supply system. It was found theoperator did not clean the filter as well as the tower tanks as per the cleaning schedule.Also, there was neither daily monitoring nor adjusting of water pressure. Besides, theelectricity for water pumping and chlorine use are high. When the electricity cost couldnot be reduced, chlorine usage is then reduced instead. As a result, the biologicalquality of the treated ground water could not pass the standard of drinking ground water(Ministry of Industry, 2542). Moreover, there is a drought problem during the dryseason. The amount of ground water being pumped is low, which caused low waterpressure in the water pipes. The water demand is getting higher, but the water supply isnot adequate. In addition, the ground water containing limestone or high hardnesscauses a blockage in the water pipes. Water supply distribution in some areas has to bere ...
