Nant Morlais River Restoration Survey

Closed 26 Jan 2024

Opened 5 Jan 2024


We invite you to share your thoughts and perceptions of the Nant Morlais catchment in this online survey. We welcome your ideas on how we can support community resilience through a healthier environment, reduced risk of flooding and drought and a more pleasant and green space.

The Nant Morlais

The Nant Morlais is a tributary of the River Taff. It flows for approximately 9km from Merthyr Common, through Merthyr Tydfil town centre and into the Taff opposite Merthyr Tydfil Fire Station.

Sadly, the Nant Morlais is failing to meet the standards imposed by the Water Framework Directive (WFD) to encourage a healthy environment.

The river is subject to various urban and land use pressures, habitats are under-strain and river processes are disrupted, meaning reduced resilience to a changing climate.

The project

Natural Resources Wales (NRW) is seeking to deliver aspects of the South Wales Central Area Statement “Working with Water”.

To support NRW with this, JBA Consulting is undertaking an investigation into how improving the river corridor and in-channel processes might benefit the community of Merthyr Tydfil, improve resilience to environmental hazards such as flooding and drought, and reduce risk in a changing climate.

Project aims

This project aims to assess the Nant Morlais catchment for opportunities to:
• restore / replicate more naturalised catchment responses;
• undertake solutions to manage surface waters, particularly where they exacerbate water quality failures;
• restore the river within the urban landscape; and,
• provide community benefits, raise awareness and encourage involvement.

Why your views matter

Engaging and working with the Merthyr Tydfil community is essential to identifying improvements, putting them in place and ensuring they remain effective in the years to come.
