    The GiAvyn© Fawr scheme of the A/bertillery aiid Distriat Water Bo-ard, whicli supplies the XJrhoii Districts of iihertillery, Ahercarii, Ihisca, and the major portion of ilynyddislwyii, continues to make excellent progress. During' 1926 the work on the dam has proceeded at a rapid pace. Half of the dam, has reached its maximum height of 166 feet above stream level. The ovei’flow weir along the top has been completed, together with eight of the sixteen arches, carrying the road- way. The thickness of the base of the dam is 124 feet, and the extreme length when completed will be 800 feet. The reservoir, when completed, will have a holding capacity of 400. million gallons. The yield ot water will be 2^ million gallons per day, one third of which must be sent do^wn the stream as compensation water, thus leaving a, balance of .1^ millioai gallons of water per day which will be available for supply. The Storage capacity of the reservoir will be sufficient even allowing for a drought of 166 days. The height of the resei’voir above sea level is from 1,700 to 1,800 feet, and 10 to 15 degrces of frost is frequently registered. On April lat, 1926, the Abertillery and District Water Board took over from the constituent authorities (Abertillery, /Vbercam, Eisca, and Mynyddislwyn Urban Districts) the entire control of the water undertaking, and are now respons- ible for all the water mains and seiwices in the Board’s area, also the making of water charges, and the collection of the water rates. The Shon Sheffrey spring, in the area, of the Tredegar Urban District Council, is reported toi be in every way satisfactoiy. This spring supplies the Iredegar Urban Area, and a considerable portion of the Bedwellty Urban District. Ihe waiter undertaking of the Ebbw Vale District, which supplies that district, Nantyglo and Blaina, and part of the Tredegar Urban District, maintains a constant supply. The water' is taken from two reservoirs situate on the Idan- gynider Mountain, and is conveyed to' the districts by cast iron gravitating mains. It is pleasing to note the defective filter beds have now been renewed, and are satisfactory. The water supply at Blaenavon was found to be extremely unsatisfactory. Investigations were made which resulterl in the! presentation of a detailed and • diaustive report to the County Public Health Committee, and which was dis- ci ssed at their quarterly meeting, held on Monday, jSToivember 29th, 1926. After the report liad been considered by the County Public Health Committee, copies were sent to the Blaenavon Urban District Council for their consideration and m-cessary action. A special report has been issued upon this subject.
