Mawr - Lliw Reservoirs Country Park

Lliw Reservoirs Country Park

There are two man made reservoirs near the village of Felindre, in the Lliw valley called the Lower Lliw Reservoir and the Upper Lliw reservoir. The reservoirs are managed by Welsh Water. The countryside around the reservoir is open to the public for recreational purposes.

The Lower Lliw Reservoir (or Felindre Reservoir) was originally opened in 1863 to provide water for Swansea and the surrounding area costing £160,000 to create. The Upper Lliw Reservoir opened in 1892 and cost £116,000 to build. Subsequently the Lower Lliw Reservoir was reconstructed between 1976-78 with inclusion of new rockfill dam, new overflow spillway and new pumping station.
