238 FORESTS, WOODS, AND TREES 



Elan and Claerwen area, 45,562 acres, supplying Bir- 

 mingham, and with a good afforestation scheme, is fully 

 described on pp. 101-104. 



Milford Haven Urban District Council obtains its water 

 supply from three reservoirs at Fordway, with a gathering 

 ground of about 200 acres, between 92 and 190 feet eleva- 

 tion. This area is leased by the Council, and comprises 

 40 acres of arable land, 155 acres of hill pasture and moor, 

 and 5 acres of plantations. There are some habitations and 

 farm-steadings on the gathering ground ; and to deal with 

 the contamination from these, a system of drainage with 

 cesspits and small filters was adopted, which is reported 

 to be satisfactory. 



Llanelly obtains its water supply from two gathering 

 grounds with a total extent of 4398 acres : 



1. Lliedi Valley, with two reservoirs, 4048 acres, be- 

 tween 200 and 950 feet elevation, comprising 400 acres of 

 arable land, 3000 acres of hill pasture and moor, and 648 

 acres of plantations. 



2. Cwm Trebeddrod, with one reservoir, 350 acres, 

 between 200 and 550 feet elevation, comprising 50 acres 

 of arable land, 250 acres of hill pasture, and 50 acres of 

 plantations. 



On the Lliedi area, there are 509 inhabitants and 102 

 dwelling-houses and farmsteads ; and the Corporation own 

 only 100 acres in all. On the Cwm Trebeddrod area there 

 are 50 inhabitants and 10 dwelling-houses and farmsteads, 

 and the Council own only 15 acres. 



The risk of contamination would appear to be great, but 

 stringent bye-laws for the prevention of pollution have been 

 made under section 25 of the Llanelly Waterworks Act, 

 1909. " The gathering ground is inspected, and all sanitary 

 arrangements in the houses on the area are kept under 

 supervision. The farmyards are drained on to adjoining 

 lands and the watercourses are kept clear." The bye-laws 

 provide that sanitary arrangements shall be made by owners 

 and occupiers of lands on the drainage area. No pigs may
