    As of 2017, the New Orleans pumping system - operated by the Sewerage and Water Board - can pump water out of the city at a rate of more than 45,000 cubic feet (1,300 m 3) per second. [1] [2] The capacity is also frequently described as 1 inch (2.5 cm) in the first hour of rainfall followed by 0.5 inches (1.3 cm) per hour afterward. [2]

  3. Limber hole - Wikipedia

    en.wikipedia.org/wiki/Limber_hole

    A limber hole is a drain hole through a frame or other structural member of a boat designed to prevent water from accumulating against one side of the frame, and allowing it to drain toward the bilge. Limber holes are common in the bilges of wooden boats. The term may be extended to cover drain holes in floors.

    en.wikipedia.org/wiki/Dry_running_protection

    Dry running protection, also known as dry-run protection or dry-running protection, is a type of protection mechanism to prevent a rotor, pump or stirrer shaft from operating without any medium added, as the bearing and shaft seal might be damaged if the motor is run while dry. [1]

    Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").

    Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types: Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) Surface and ground water stagnation; Trapped water stagnation.

  9. Hydraulic ram - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_ram

    The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination ...
