History of Cray Reservoir

Cray Reservoir was built to supply Swansea with mains water. It was completed in 1906, after eight years of construction, and at that time was regarded as a massive technical achievement. The reservoir still supplies water to the River Tawe valley and north Swansea and it has a reputation for providing high quality water.
