Achieving better, more efficient use of our resources is a key driver behind sustainable communities.

And new technologies to promote heat recovery can help reduce energy consumption.

According to engineer David Bromley, rethinking a city’s sewer system is a good example.

Bromley is the project director for the proposed Rampart Avenir Community for Clean Technology.


DAVID BROMLEY:
There’s a lot of heat within sanitary sewers. And if we could capture some of that heat, it’s amazing what we could probably do with it from an energy standpoint.
So there are a number of coatings that are being developed right now that you can actually put inside the sanitary sewer and change that sanitary sewer not just being a sanitary sewer but also being a heat exchanger or a district heating system. If you can imagine now instead of the sanitary sewer being just a regular old sewer, that’s probably in some bad condition problems because it’s old and needs to be repaired, that coating does the repair , so that’ one benefit. But the second thing it changes it into a district heating system. And that will have a huge significant benefit to that community.

According to David Bromley, this is just one clean technology being assessed by the MARS group at the University of Toronto.
