WATEE CATCHMENT AREAS 237 



Vyrnwy catchment area, 22,742 acres, supplying Liver- 

 pool, and with a good scheme of afforestation, is fully 

 described on pp. 88-94. 



Machynlleth Urban District Council obtains its water 

 supply from Esgeireira reservoir, Llanwrin, with a gathering 

 ground of 271 acres, reported in Journ. Board of Agriculture, 

 xi. 471 (1904), to be owned by the Council, and to com- 

 prise 204 acres of hill pasture and 67 acres of woodland. 

 The Clerk states in a letter that only 2>\ acres are owned 

 by the Council. 



Llanidloes obtains its water supply from a gathering 

 ground of 260 acres at Llangurig, all hill pasture and 

 moorland. None of it is owned by the Town Council. 

 The water is filtered, but no other precautions are taken 

 against contamination. 



Newtown and Llanllwchaiarn Urban District Council obtain 

 their water supply from Mochdre reservoir, with a gathering 

 ground of 1821 acres, between 662 and 1391 feet elevation, 

 in Mochdre and Kerry. The total area, of which only 10 

 acres are owned by the Council, comprises 334 acres of 

 arable land, 1377 acres of hill pasture and moor, and 110 

 acres of plantations. There are 17 farm-steadings on the 

 gathering ground, and a careful inspection is made monthly 

 of each farm. Cesspools are provided to prevent the sewage 

 getting into the intake stream ; and no flood water is taken 

 into the reservoir. This area would seem to be suitable for 

 an afforestation scheme, which would do away with the 

 arable land and farm-steadings, and prevent possible 

 contamination. 



Aberystwyth obtains its water supply from Llyn Llygad 

 Eheidol, a small lake or tarn just below the summit of 

 Plynlimmon, with a gathering ground of 133 acres, between 

 1665 and 2468 feet elevation, all moorland without any 

 habitations, and not owned by the Town Council. There is 

 no filtration.
