Buxton Urban District Council obtains its water supply- 

 in part from two gathering grounds — Coombs Moss area, 

 200 acres, between 1300 and 1400 feet elevation, with 

 two reservoirs at Lightwood ; and Stanley Moss area, 1700 

 acres, between 1450 and 1550 feet elevation, with one 

 reservoir. These areas, which are not owned by the 

 Council, are entirely moorland, without habitations, farm- 

 steads, or plantations. The water is passed through high- 

 pressure filters. 



The Derwent Valley Water Board supply water to 

 Derby, Leicester, Nottingham, and Sheffield from a catch- 

 ment area of 13,220 acres at the head- waters of the river 

 Derwent in High Peak, Derbyshire and Yorkshire. It is 

 mostly rough pasture and heather-covered grouse moors, 

 with steep hill slopes, the elevation ranging from 700 to 

 1793 feet. The Board own 1184 acres, fringing the two 

 reservoirs, Howden reservoir (870 feet altitude) and Derwent 

 reservoir (776 feet altitude). There were a few farm-houses 

 on this part of the area which was mostly rough grazing, 

 but there now remain only three dwelling-houses, one 

 unoccupied and two inhabited by the Board's workmen. 

 The sewage from all three houses soaks through the land 

 before it reaches the reservoir. The Board have no rights 

 over the privately owned portion of the catchment area, but 

 they have power to agree as to the drainage of the lands 

 for more effectually collecting, conveying, and preserving 

 the purity of the waters flowing on such lands into the 

 reservoirs. 



The Board have planted up to February 1918, within 

 the boundary of their land, 310 acres of plantations at eleva- 

 tions between 700 and 1500 feet. There are a few 

 plantations outside the Board's lands. The annual rainfall 

 of 59 stations for 13 years varied from 34 to 61 inches. 

 All the water, except that supplied to Sheffield, is passed 

 through sand filters at Bamford.
