It sounds uncanny, generating warm water from the sewer system. But it is sustainable. The average temperature of sewer-water is 18 degrees. At the moment, this energy flows, without being used, through the drains to the sewage filtration system. With the Hydrea Thermpipe, an innovative 'energy drill pipe' designed by Heijmans, this warmth can be reused in a clean and safe way. This way, the energy-neutral system is one step closer.

The warm water from this installation can, via a heating pump, heat the adjacent parcels (the system works up to a distance of about 300 metres). By reversing the system, it is also possible to cool office buildings and factories. In one transport pipeline, a heating and cooling system is combined. That saves lots of energy.

Recorded at TEDxBinnenhof 2014 at The Ridderzaal in The Hague
