The SHARC sewage heat recovery system has been installed in a number of places in Canada and North America.
In the UK we are already undertaking a number of feasibility studies for district heating systems, the healthcare sector and large commercial property owners.
Who we work with:
- District heating systems
- Residential developments
- Public facilities
- Commercial buildings
- Industrial complexes
- Shopping centres
Borders College, Galashiels, Scotland
Backed by investment from Equitix and the UK Green Investment Bank, the SHARC heat recovery system intercepts waste water from a sewer close to the local treatment works operated by Scottish Water.
The system uses a heat pump to amplify the natural warmth of waste water and the heat produced is being sold to Borders College under a 20-year purchase agreement, producing savings in energy, costs and carbon emissions.
The system now provides around 95% of the heat needed by the Galashiels Campus and does not impact on the normal operation of the local waste water network. Technical Presenter

Seven35 Building, North Vancouver, Canada
The average water usage per town home is 250 gallons per day at an average exiting temperature of 20°C (68°F).
The SHARC system has FHP heat pumps with double walled, vented heat exchangers that recover waste heat from the exiting raw sewage and moves that heat into 6-120 gallon DHW storage tanks.
In the Seven35 Building, flow meters, temperature sensors and electrical meters were installed throughout the sewage heat recovery system in order to monitor and log both the system operation and the amount of energy used and recovered by the SHARC system.
The Gateway Theatre, Richmond, BC, Canada
The Gateway Theatre project in Vancouver, completed in 2012 is a 50,000 sq ft multi-use public theatre facility. As part of the city’s carbon reduction strategy the SHARC system was installed reducing the facilities emissions by 50 tonnes per year. The existing system was an incremental heat pump based system supplied by a boiler and cooling tower using 29 heat pumps. With a design flow of 250 GPM from a city source 1 million btu/ hr are produced. This installation is the first waste water recovery system in a public facility in Canada.
Sail Condominium Project, University of British Columbia, Canada
The Sail project is a new 172-unit condominium project. This is the largest SHARC installation to date and is the highlight of a sustainable community plan at the University British Columbia. The SHARC produces hot water and contributes to heating the building via radiant floor heating. The system generates 220,000 BTU’s per hour, reducing emissions by 100 tonnes per year and operates at 80% efficiency.
