Carmarthenshire Bryngwyn WTW

  Bryngwyn Water Treatment Works (WTW)
Situated on high ground just  South of Llandeilo, the Works is used to produce drinking (potable) water for West Glamorgan, from raw water which is piped by gravity from Usk Reservoir. When Usk is empty, water is abstracted by electric pumps from the Towy nearby (see pages on Llyn Brianne Reservoir).
