VII. Severn Basin, Devon, and Cornwall 



Twenty local authorities and two private companies 

 obtain their water supply from gathering grounds aggre- 

 gating 34,103 acres, of which 10,862 acres are owned by 

 nine Corporations. The most important areas owned by 

 local authorities are those of Plymouth, Torquay, Paignton, 

 and Stratford-on-Avon. A good deal of planting is being 

 regularly carried out by the Torquay Corporation on their 

 area. Plymouth is contemplating a scheme of afforestation 

 after the war. There are considerable plantations on the 

 Taunton, Exmouth, Penzance, and Wellington (Salop) areas. 

 The Plymouth water catchment area has an interesting 

 history, and is exceptional in the amount of water which it 

 stores up. 



Church Stretton Urban District Council obtains its water 

 supply from a gathering ground of 700 acres, between 900 

 and 1550 feet elevation, on the Long Mynd Hill in Shrop- 

 shire. The area, of which none is owned by the Council, 

 is all hill pasture and moor, without habitations, farmsteads, 

 or plantations. The water is not filtered, and no special 

 measures are taken on the gathering ground against 

 contamination. 



Wellington (Salop) Urban District Council obtains part 

 of its water supply from the Wrekin and Buckatree 

 streams, with a catchment area of 500 acres, between 500 

 and 1284 feet elevation. The gathering ground, none of 

 which is owned by the Council, comprises 170 acres of hill 

 pasture and moor, and 330 acres of plantations, and has 

 one small farmstead and a refreshment house upon it. The 

 water is filtered, and sterilised by means of chlorine.
