Council to progress with Gruggies Burn flood alleviation scheme

The project aims to address significant flooding caused by the burn’s steep catchment and rapid runoff. Key elements of the full scheme, which was agreed by members, include installation of a four-metre wide diversion culvert from Strowans Well Road to Hunter Burn outfall into the River Clyde; construction of a new inlet structure to slow and divert water; new coastal defence walls and embankments; and flood gate installation. 

Following a decision taken at a full Council meeting on Wednesday, a contractor for the Gruggies Burn project will now be sought and appointed before a deadline set by the Scottish Government of 31st March 2026.  

The Scottish Government will provide 80% of funding for overall costs at the final tender stage. This will cover construction, site investigations, design works, major utility diversions, and ancillary works with the Council providing the other 20% in funding. 

This equates to a £35.76million spend by the Scottish Government with West Dunbartonshire Council contributing £8.94million. 

The full scheme will significantly reduce flood risk for around 631 properties and major roads, delivering a whole-life benefit of £70m.  

Convener of Infrastructure, Regeneration and Economic Development, Councillor David McBride, said: “This is a vital investment for Dumbarton East. Residents have lived with the fear of flooding, and this scheme will provide the protection and peace of mind they deserve. It’s a complex project, but the benefits for our community are clear and long-lasting."  

Vice Convener, Councillor Lawrence O’Neill, added: “The full scheme will not only safeguard homes, businesses and transport routes but also strengthen our coastal defences for generations to come. I want to thank the team who have worked so hard to get the project to this crucial stage.”
