To provide a water pumping device that accurately obtains the amount of groundwater that can be pumped in a water pumping well and that pumps groundwater on the basis of the obtained amount of water that can be pumped, even at low cost.SOLUTION: A water pumping device 10 comprises a water pump 20, a water level measuring device 30, a water pumping amount measuring device 40, and a control device 50. The control device 50 comprises a first calculation unit 51 for calculating an appropriate water level decrease Hd1 in a predetermined first period, a second calculation unit 52 that calculates an inflow amount q3 flowing in a predetermined first period, a first water pumping amount setting unit 53 that sets a first pumping amount Qmax that can be pumped in a predetermined second period, and a pump operation control unit 56 that controls the operation of the water pump 20 such that a water pumping amount Q does not exceed the first water pumping amount Qmax in a predetermined second period.SELECTED DRAWING: Figure 1
【課題】低コストでありながら、揚水井戸における地下水の揚水可能量を精度よく求め、求めた揚水可能量に基づき地下水を揚水する揚水装置を提供する。【解決手段】揚水装置１０は、揚水ポンプ２０と、水位計測装置３０と、揚水量計測装置４０と、制御装置５０と、を備える。制御装置５０は、所定の第一期間において適正水位低下量Ｈｄ１を算出する第一算出部５１と、所定の第一期間に流入した流入量ｑ３を算出する第二算出部５２と、所定の第二期間において汲み上げ可能な第一揚水量Ｑｍａｘを設定する第一揚水量設定部５３と、所定の第二期間において揚水量Ｑが第一揚水量Ｑｍａｘを超えないよう、揚水ポンプ２０の作動を制御するポンプ作動制御部５６と、を備える。【選択図】図１
