A liquid transfer device having a housing with a top end, a bottom end, a sidewall, and an inner cavity. The sidewall has an inner surface and an outer surface. There is a plurality of openings traversing said sidewall. Also present is a filtering surface that covers the openings. The water or other liquids are pumped or transferred with a pump contained inside the inner cavity, with a fluid exit used for carrying the water out towards exterior hosing.

1. A liquid filtering and transfer device, comprising: a substantially rigid, space enclosing housing said housing having a top end, a bottom end, a sidewall, and an inner cavity and wherein said sidewall of said housing has an inner surface and an outer surface;an electrically driven fluid transfer
1. A liquid filtering and transfer device, comprising: a substantially rigid, space enclosing housing said housing having a top end, a bottom end, a sidewall, and an inner cavity and wherein said sidewall of said housing has an inner surface and an outer surface;an electrically driven fluid transfer pump having an inlet manifold, surrounded by an inlet strainer, located in a vicinity of its lower end, said fluid transfer pump being disposed within said inner cavity of the housing, and having said inlet manifold located in a proximity of said bottom end of the housing, and wherein said inlet strainer has a plurality of strainer openings fluidly connecting said inlet manifold to said inner cavity, and wherein said strainer openings have a substantially similar strainer opening size;a plurality of openings traversing said sidewall, each of said openings fluidly connecting said inner surface of said sidewall to said outer surface of said sidewall, and wherein said openings have a maximum size that is smaller than said strainer opening size; an electrical power switch operative to switch said electrically driven fluid transfer pump between an operational state and a standby state; anda restrained floatation device comprising a restrained float restrained to move only in a substantially vertical direction, said restrained floatation device being functionally connected to said electrical power switch such that when a fluid level within said inner cavity of the housing falls below a preset height, said electrical power switch switches said electrically driven fluid transfer pump to said standby mode, thereby preventing said fluid transfer pump from running while dry and being damaged. 2. The device of claim 1 further comprising a substantially contiguous, filtering surface that is substantially permeable to a fluid being transferred, said filtering surface being located in proximity to either said inner surface of said sidewall, or said outer surface of said sidewall, and covering said plurality of openings. 3. The device of claim 1, wherein said restrained floatation device further comprises an elongated element having adjustable limits, and wherein said restrained float is disposed between said limits. 4. The device of claim 1, further comprising a fluid level indicator having a piston head disposed in a fluid level indicator casing 220, said casing having a fluid intake valve 230 and a fluid outlet valve 240; and a visible level-indicator 250, said visible level-indicator 250 being connected to said piston head such that an indication of a fluid level may be discerned external to said liquid filtering and transfer device. 5. The device of claim 1, further comprising a plurality of substantially spiral grooves 260, said plurality of spiral grooves being disposed on said outer surface of said sidewall and traversing said plurality of openings. 6. The device of claim 1, wherein a filtering surface is disposed within said inner cavity of the housing. 7. The device of claim 1, wherein a filtering surface is disposed on the outer surface of said sidewall. 8. The device of claim 1, further comprising a burrowing attachment, fixedly connected to said liquid filtering and transfer device in a vicinity of said bottom end of the housing. 9. The device of claim 1, wherein said electrically driven fluid transfer pump is a submersible water pump. 10. The device of claim 1, further comprising a fluid exhaust pipe, said fluid exhaust pipe connecting an exhaust manifold of the fluid transfer pump to an external environment. 11. The device of claim 10, wherein said exhaust pipe further comprises a power cord. 12. The device of claim 1, further comprising a top cover, said top cover capable of admitting additional piping; a visible level-indicator, a power cord and a middle cover positioned to provide an upper storage volume. 13. The device of claim 1, wherein a width of said bottom end of the housing is less than a width of said top end of the housing, thereby forming a pitched sidewall. 14. The device of claim 1, further comprising at least one handle. 15. The device of claim 1, further comprising a securing mechanism that immobilizes said housing. 16. The device of claim 1, further comprising a thermostat and a heater, said heater activating a heating element when triggered by said thermostat.
