As the water supply facilities are recently getting larger, the domestic waterworks become multi- regional water supply system. Large water supply facilities generally consist of the intake pumping station, water treatment plant and water supply/distribution facilities. Although the pumping stations and the pipeline systems are used to pump up water, it often happens pipeline damage and flooding accident by the water hammer. In this paper, the intake pumping station is guaranteed by both the computer simulation and the field test analysis. This study is contributed to the safe operation program for the pumping station in which results of the adjustment on the safety plan of the pumping station, the air valve and the valve closing time.

Water supply facilities are recently getting larger according as domestic waterworks become multi - regional water supply system. Large water supply facilities generally consist of the intake pumping station, water treatment station and water supply & distribution facilities. Although pumping stations and pipeline systems are used to pump up water, it often happens pipeline damage and flooding accident by the water hammer. As a result of this study, a pumping station is guaranteed by the computer simulation and field test analysis. Therefore these are contributed safety operation in pumping station through adjustment of the pumping station safety plan, air valve and valve closing time.

The thesis is performed to find out the stability of Water-hammer that is happened when additional water needs demanded. At first, the water supply construction project is planned to supply 6,000 m3/day through 179㎞ pipeline. But additional demand 0,200 m3/day) happened from Cheong-Ra Water reservoir. In this situation, Air-chamber(4 m3) & Vacuum breaker valve(Φ100 ㎜) are needed to prevent Water-hammer. When the additional water is supplied, the existing facilities(Air-chamber, Vacuum breaker valve) are sufficient to alleviate shock not changing capacity alteration, judging from the airspace change and rise. Therefore, there is no problem for Water-hammer by installing Air-chamber(4 m3) and Vacuum breaker valve(Φ100 ㎜) at the top of Yeo-ju hill.
