PURPOSE:To enable to recover muddy water from a remote liquid supply source only by extending hoses, 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 one end 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. By evacuating the inside of the pipe 3 and a separation tank T2 through operation of a vacuum pump 1, a mixture of sand, water, air, etc. is carried into the separation tank T2 from the supply source 4. When the level of liquid in the separation tank T2 is raised to a predetermined level, the pump 2 is set into operation. In the separation tank T2, only gases are collected at an upper portion, while sand, sludge, etc. are carried together with liquid to a place where they are to be dumped, by the function of the submergible pump 2. |
