These apartment buildings will be heated by sewage — yes, really
Sen̓áḵw is a residential development in Vancouver led by the Squamish Nation, featuring 6,000 rental apartments across 11 towers, including affordable housing for Indigenous communities.
The project incorporates a $30-million district energy system that captures heat from Vancouver's main sewage line to provide heating for the buildings, saving an estimated 4,000 tonnes of greenhouse gas emissions annually.
This energy system involves hot-tapping into a large sewer main with pipes and heat pumps, distributing heat while using boilers only as backups.
