Eglwys Nunydd

The Eglwys Nunydd is a 260-acre (110 ha) supply reservoir in Margam, Wales originally constructed to provide water for the large steelworks at Margam and specifically for cooling water for the cold rolling mills at the eastern end of the works. Much of the water for the hot end of the plant is abstracted from the Rivers Afan and the Ffrwdwyllyt as they flow through the dock feeder.
