Wastewater used to warm up heat network

Heat harnessed from wastewater from Scottish Water's treatment works in Forthside is being used to heat a number of buildings in the Forthside area of Stirling.

The first of its kind in the UK, the £6 million scheme uses a unique mix of cutting-edge technologies to take heat from wastewater and turn it into low carbon, low cost heating.

Heat harnessed from wastewater is processed through an on-site energy centre and then distributed along Stirling Council’s district heat network.

The network also provides heating to nearby The Peak Leisure Centre, Forthbank Stadium Conference Centre and St Modan’s High School. The network was been designed so that there is future potential for expansion to include more businesses and nearby housing. 

The scheme will greatly contribute towards Scotland’s zero-carbon targets by helping to save a projected 381 tonnes of carbon per annum.

Managing director of Scottish Water Horizons, Paul Kerr, said: “We’re really proud of this low carbon project in Stirling. Not only will Stirling Council and end users benefit from reduced carbon and energy costs, the scheme is providing Scottish Water’s Stirling Waste Water Treatment Works with the majority of its energy requirements, helping support Scottish Water’s target of reaching net zero emissions by 2040.

“The project has great potential for replication throughout Scotland, with several opportunities already under investigation, and we’re always on the lookout for more.”

Stirling-based building services company FES delivered the project on behalf of Scottish Water Horizons and Stirling Council.

Stirling Council leader, Councillor Scott Farmer, said: “Making Stirling the first place in the UK to harness this mix of cutting-edge renewable technologies shows Stirling Council is determined to lead the way on tackling climate change by reducing our carbon emissions and improving energy efficiency.

“This innovative initiative will deliver cost-saving benefits to the council and residents, generate additional income for many years to come and benefit communities in the form of regeneration and jobs in the growing renewables sector.”

The project has been delivered by Scottish Water Horizons in partnership with Stirling Council, with additional funding provided by the Scottish Government.
