Taf Bargoed Wetland

A residential street adjoining Parc Taf Bargoed in Treharris was struggling with repeated flooding in wet periods throughout the year, due to the run off and aspect of the site.

After topography surveys and ecological assessments were carried out, plans were developed to create a drainage solution on a patch of derelict land within the park. The idea was to create a series of catchment ponds and redirect water from culverts into the river which runs perpendicular to the site.

Three ponds were be created to support local wildlife and attract additional species which could use the ponds as habitat. Although the ponds were lined with concrete to ensure longevity, planting with native freshwater species was essential to provide habitat for invertebrates and amphibians.

An elevated boardwalk was also created, which allowed a circular route across the site, creating a new path which has become popular with local dog walkers, allowing more of the park to be enjoyed by residents.

To further increase the biodiversity of the park, trees were planted around the perimeter of the site and a bat tower and bug hotel were installed.

The project has been completely successful, with local residents no longer suffering from flooding. A new area of the park has been opened up to visitors, and native plants and wildlife are now thriving.
