How it works

Unlocking Low Carbon Heat from Waste Water

Every day, buildings across Scotland heat water for showers, dishwashers, washing machines and industrial processes – only for that warm water to be flushed away. With average waste water temperatures around 20°C, there’s an untapped energy source flowing beneath our feet.

We enable organisations to harness this heat by helping them access the sewer network for innovative heat recovery.

By facilitating the installation of waste water heat recovery systems, we help partners and developers tap into a consistent, renewable energy source. These systems use heat exchangers and heat pumps to recover thermal energy from the sewer network and repurpose it for heating buildings, campuses or entire districts.

While each application is tailored to the specific needs of a site, the core principle remains the same:

• Access the sewer network in the right location
• Install heat recovery technology to extract thermal energy
• Integrate with existing or new heating systems

We work closely with developers, local authorities, and energy partners to ensure technical viability, compliance and long-term performance.
