Water Usage
The water is used for river control and to compensate for the water retained by all three dams, along with supply into the drinking water system and hydroelectricity generation. Drinking water must be pumped to treatment works rather than using gravity flow like in the other two reservoirs, increasing costs. The drinking water is treated at Bamford water treatment works by Severn Trent Water. Treated water flows down the 28 miles (45 km) long Derwent Valley Aqueduct to a covered service reservoir at Ambergate to supply clean water to the cities of Derby and Leicester in the East Midlands of England. The aqueduct passes through the park of Chatsworth House on its way south. The path of the aqueduct is marked by a series of distinctive valve houses built of stone & domed steel access chambers. A tunnel carries some of the water from the Derwent Valley eastwards through the hill and into the lower of the two Rivelin Dams in order to supply Sheffield.

Famous quotes containing the words water and/or usage:
“I respect the ways of old folks, but the blood of a rooster or a goat cannot turn the seasons, change the course of the clouds and fill them up with water like bladders. The other night, at the ceremony for Legba, I danced and sang my fill: I am a black man, no? and I enjoyed it like a true Negro should. When the drums beat, I feel it in the pit of my stomach, I feel the itch in my hips and up and down my legs, I have got to join the party. But that is all.”
—Jacques Roumain (1907–1945)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
