Lift irrigation schemes must accomplish two main tasks: first, to carry water by means of pumps or other way, from the water source to the main delivery chamber, which is situated at the top most point in the command area.
Ghana Water had requested a 400% tariff increase to fully cover costs, but the regulator had pared down the request substantially, citing concerns about affordability. [4] Between 1990 and 1997, the average water tariff in Ghana's urban areas had been in the range of US$0.10 to US$0.15 per m³.
Some irrigation schemes use water wells for irrigation. As a result, the overall water level decreases. This may cause water mining, land/soil subsidence, and, along the coast, saltwater intrusion. Irrigated land area worldwide occupies about 16% of the total agricultural area, and the crop yield of irrigated land is roughly 40% of the total ...
Sea level rise can make coastal flooding worse. In some areas there are also risks of glacial lake outburst floods. There are many adaptation options for flooding: [30] Installing better flood defences such as flood barriers, sea walls and increased pumping capacity [31] Installing devices to prevent seawater from backflowing into storm drains [32]
Michigan Ditch in northern Colorado carries water from the North Platte River watershed over Cameron Pass to the South Platte River watershed.. Interbasin transfer or transbasin diversion are (often hyphenated) terms used to describe man-made conveyance schemes which move water from one river basin where it is available, to another basin where water is less available or could be utilized ...
A photovoltaic pumping system to pump 25 cubic metres per day requires a solar array of approx. 800 Wp. Such a pump would cost US$6000, since the total system comprises the cost of modules, pump, motor, pipework, wiring, control system and array support structure. PV water pumping has been promoted successfully in Kordofan state in Sudan.

The pumping station, together with two accumulators, was situated in the Darling Harbour district, and the original steam engines were replaced by three electric motors driving centrifugal pumps in 1952. [29] The scheme remained in private ownership until its demise in 1975, and the pumping station has since been re-used as a tavern. [25]
