Residents who live near a beauty spot are campaigning to stop a 100-acre water treatment plant from being built there. Thousands living in Merthyr Tydfil have signed a petition opposing the proposals by Dŵr Cymru Welsh Water.
If the plans are accepted the plant would take up swathes of land north of Merthyr Tydfil and east of Trefechan. The area, in Pontsarn, borders Brecon Beacons national park, Morlais castle and quarries, the Taff Trail, and the Taf Fechan site of special scientific Iiterest.
Residents have described the proposal as "atrocious" and worry about the impact it would have on local wildlife as well as recreation. After reviewing a number of areas Dŵr Cymru said the chosen site is the most appropriate for the plant and public consultation is under way.
