PURPOSE:To enable to recover muddy water from a remote liquid supply source, by extending a liquid drawing pipe into the liquid supply source, and extending a discharge port of a submergible pump to the outside of a separation tank. CONSTITUTION:A suction hose is connected to an end portion 3a of a liquid drawing pipe 3 and it is extended into a liquid supply source 4. Similarly, a discharge hose is connected to a discharge port 2b of a submergible pump 2 and extended to a place where waste matter is to be dumped. Through operation of a vacuum pump 1, the inside of the pipe 3 and a separation tank T2 is evacuated, so that a mixture of sand, water, air, etc. is drawn into the separation tank T2 from the liquid supply source 4. When the level of liquid in the separation tank T2 is raised to a predetermined level, the submergible pump 2 is set into operation. In the separation tank T2, gases are carried into a gas collecting tank T3 from an upper portion of the tank T2, while sand, sludge, etc. are carried together with liquid to the place where they are to be dumped, by the function of the submergible pump 2. |
