We are always looking at ways to help the drive to reach net zero. In an innovative project, our Bluewave team are working with local councils and specialist suppliers to use the heat generated in the sewer network, as a low carbon heating source in the community.
Using heat from our sewer network as an alternative energy source
Sewers have an average ambient temperature of 17 degrees centigrade. With heat exchange technology, we can use some of the excess heat in the network to provide an alternative heat source for existing buildings and new developments. It works by carrying hot water to serve homes and businesses – like a giant central heating system.
An innovative project to reduce carbon emissions
We are currently working on a project with Worthing Borough Council to eventually link up 20 public buildings including the town hall, a hospital, a leisure centre, schools and law courts, as well as new developments. The project has the potential to reduce carbon emissions by up to 3,000 tonnes a year - the equivalent of the energy used by 1,325 average-sized homes.
Future opportunities to use heat from sewer networks
Only a handful of heat networks currently exist in the UK, however looking to the future, we can use the same technology to provide heat for agricultural use, such as greenhouses during the winter. We are already discussing with the Department for Business, Energy and Industrial Strategy (BEIS) how our assets can support a Heat Network Zoning Pilot, to highlight where the greatest sources of heat can be found in our network.
Working in partnership to find innovative solutions
Present and future environmental challenges mean we need to find new ways to achieve more, but with the same resources. Innovative and collaborative projects like these can help us move towards a more sustainable future for everyone.
