A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

The pumps supplied water to the palace kitchen, the royal confectionery, the stables and to the royal deer park. An underground headrace from the canal drove an overshot water wheel with a diameter and a width of 2 meters which in its turn operated a beam and two pumps in brass cylinders with a diameter of 18 cm and a stroke of 55 cm.
An Egyptian qullah, set in drafts to cool interiors. Porous pottery and coarse cloth maximize the area for evaporation. An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water.
A secondary, typically battery-powered sump pump can operate if the first pump fails. A battery-powered secondary pump will have a separate battery and charger system to provide power if normal supply is interrupted. [citation needed] Alternative sump pump systems can be driven by municipal water pressure. Water-powered ejector pumps have a ...
A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to ...
The device uses the water hammer effect to develop pressure that lifts a portion of the input water that powers the pump to a point higher than where the water 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 higher in elevation than ...
