Sharc secures grant to deploy waste water heat recovery systems in Scotland


Sharc Energy Systems, the wholly-owned European unit of International Wastewater Systems (IWS), has been awarded £9.8m grant to install the company’s waste water heat recovery systems at five locations across Scotland.

The latest technology enables sewers to be used to produce renewable heat, thereby generating major savings in energy, costs and carbon emissions.

The solution can be deployed across a wide range of locations worldwide to support both urban and rural customers, as well as a platform for wide scale low carbon district heating.

Granted from the Low Carbon Infrastructure Transition Programme (LCITP), the funding is managed through the Scottish Government and will facilitate the development of five new projects that would help transform heating systems at several commercial and local authority sites.

Sharc’s ‘heat-from-waste water’ technology has been earmarked to provide heat to Kelvingrove Museum and a new district heating scheme at the Clyde Gateway regeneration project in Glasgow, a leisure centre and public library in Campeltown, and a leisure centre in Orkney.

The technology works by using a heat pump to increase the warmth of waste water in sewers, such as from showers, dishwashers and washing machines, thereby generating an energy-saving and environment-friendly system for heating, cooling and hot water production in commercial premises and homes.

Over the last three years, Scottish Water Horizons and Sharc Energy Systems have been working to promote the adoption of sewage heat recovery in Scotland.

Scottish Water Horizons head Paul Kerr said: “With 32,000 miles of sewers pipes across Scotland and Scottish Water treating more than 900 million litres of waste water every year, the opportunities presented from this technology are clear to see.

“Using the sewer network to transfer heat means that the heat source can be used to supply heat to the customer as close as possible to the customer’s premises. This minimises the cost and disruption of installing new heat pipes in the street.”
