US Patent 7862713 Reservoir water filtration system

A system for reuse of water stored in a reservoir by transfer of initially filtered water from the reservoir to a vertically stacked filtration system located onshore. A flexible filter screened, porous feeder line housed within a perforated carrier pipe extends into the reservoir and is supported above the bottom of the reservoir for transfer of filtered water to the vertically stacked filtration system. The flexible filter screened, porous feeder line includes a conveyance system for retraction and extension of the porous feeder line by two cables. The feeder line is movable from the perforated carrier pipe for cleaning or replacement of the porous feeder line.
