Greener Grangetown – award winning SuDS Scheme

Greener Grangetown is an innovative scheme to better manage rainwater in the Grangetown area of Cardiff.

Using the latest techniques, this SuDS (sustainable drainage systems) scheme catches, cleans and diverts rainwater directly into the River Taff instead of pumping it over 8 miles through the Vale of Glamorgan to the sea; helping to make Grangetown a greener, cleaner place to live.

ERH-Centregreat carried out the construction work on this exciting initiative which started in November 2016, initially along the banks of the River Taff, and recently completed (mid 2018).  Work also include new trees, planters, grass channels, kerb drainage and rain gardens.

We operated as the prime contractor delivering:

In addition to the physical work, we also had a public liaison officer on site each day as it is a high-profile project in a densely populated area of Cardiff. The local residents were surrounded by the works for a lengthy period of time and needed to be regularly updated, have a place to go to ask questions and understand why we were doing the works in the way we were.

We are pleased to confirm that the works progressed well, despite some challenges along the way. This project is the first of its kind in Wales and was not without its challenges but great collaboration across the partnership delivering this project, which consists of City of Cardiff Council, Dŵr Cymru Welsh Water, Natural Resources Wales, Arup and ERH, meant we continued to progress and ultimately achieved a successful outcome for all stakeholders.

The Greener Grangetown Scheme won Engineering Project of the Year 2018 at the UK Water Industry Awards, supporting the importance of projects like this to the benefit of the environment and local communities.
