Scottish Water teams up with Canada’s SHARC Energy Systems to bite into low-carbon sewage-heat market

International Wastewater Systems Inc.

Canada-based SHARC Energy Systems has teamed up with Scottish Water to help businesses and public organisations reduce heating costs and carbon emissions.

The two companies have formed a strategic alliance to expand and accelerate the deployment of sewage-heat systems around Scotland.

 This alliance builds on the launch of the UK’s first sewage-heat recovery system –  first pioneered by SHARC Energy at Borders College in Galashiels – which aims to displace 1.8 GWhrs (Giga Watt hours) of natural gas and save 150 tonnes of carbon emissions per year.

The SHARC thermal heat recovery system developed by International Wastewater Systems has been deployed in numerous international locations, intercepts wastewater from sewers and uses heat pump technology to amplify the natural warmth of waste water.

This generates an energy-saving, cost-effective and environmentally-friendly system for heating, cooling and hot water production in commercial, residential and industrial buildings.

The new alliance is the result of two years of informal collaboration between SHARC Energy and Scottish Water Horizons, which has created a £20 million pipeline of potential installations across Scotland that, when deployed, would generate 170 GWHrs per year of heating and cooling to displace the fossil fuel currently used.

Scottish Water Horizons estimate that up to 750 such systems would need to be installed by 2020 to enable Scotland to achieve its carbon savings targets.

Andrew Macdonald, Head of Scottish Water Horizons, said: “The potential to deploy this technology is significant. Heat accounts for over half of Scotland’s total energy use and we believe that by harnessing the natural resources of our vast waste water network, we can further the development of Scotland’s low carbon economy, whilst protecting and enhancing the environment.

“Scottish Water treats over 900 million litres of waste water every year and we are determined to maximise the opportunities presented. Our alliance with SHARC Energy is an exciting opportunity which will help to accelerate the deployment of this proven technology on a wider scale, providing customers with an innovative and sustainable lower cost heating solution.”

Russ Burton of International Wastewater Systems, said: “This announcement is a very exciting step for SHARC Energy and IWS and represents the culmination of two and a half years working with Scottish Water Horizons to identify opportunities for the SHARC technology.

“Having the support from Scottish Water Horizons will give customers the confidence in the SHARC technology, positioning it as a sustainable and viable wastewater heat recovery solution.”
