A shadoof or shaduf, [1] well pole, well sweep, sweep, [2] swape, [3] or simply a lift [4] is a tool that is used to lift water from a well or another water source onto land or into another waterway or basin. It is highly efficient, and has been known since 3000 BCE. [citation needed]
This 41,000-acre clear-water reservoir in Wind Creek State Park is a favorite for residents of nearby Alexander City. Fish, swim, boat, or stay and camp: More than 150 of the park's campsites abut ...
The lower reservoir is the Conowingo Reservoir, created in the Susquehanna River by the Conowingo Dam, with a normal pool elevation of 109 feet (33 m). The power house uses excess grid capacity during off peak hours to pump water from the Conowingo Reservoir into the upper reservoir through four 25-foot (7.6 m) diameter, 343-foot (105 m ...
The reservoir at the top of the mountain covers 528 acres (214 ha), with a dam that is 230 feet (70 m) high and 5,800 feet (1,800 m) long, the largest rock-fill dam ever built by TVA. The plant serves as an important element for peak power generation and grid balancing in the TVA system.
Water in the reservoir would have fed the firefighting equipment and helped the pump stations push water to the storage tanks. But the reservoir "wouldn't have lasted forever and would not have ...
When energy demand is high, water is released from the upper reservoir to the generating plant and the water is discharged into the lower reservoir. When demand is low (such as at night), water is pumped into the upper reservoir to be used as stored energy at a later time. This is accomplished by pump-generators which serve a dual role: the ...
The city is dipping into backup water supply as local reservoirs slip below normal levels, but no water restrictions are being implemented now. Columbus dipping into reserve water supply amid ...
Water is released from the upper reservoir during periods of high demand and is used to generate electricity. What makes this different from other hydroelectric dams is that during times of low demand, power is taken from coal, nuclear, and other power plants and is used to pump water from the lower to the upper reservoir. Although this plant ...
