Celtic Vale
Natural mineral water from an artesian spring at Springvale, Longtown, at the eastern foot of the Black Mountains, Herefordshire. Black Mountain Mineral Water Company Ltd bottles it at source. The company was incorporated in 1994 and is owned by Dorinda Watkins (Companies House, 75% or more since April 2016). It was trading on 14 October 2026: accounts to December 2025 are filed and the website is live. A separate Celtic Vale Mineral Water Ltd was dissolved in December 2022. The producer says the spring yields up to 80,000 gallons a day; we haven’t checked that. Its site places the source on both the “eastern” and “western” edge of the Brecon Beacons National Park; the Longtown address fits the eastern.
