Vancouver Chooses Sewer Heat Option for Olympic Village Project
As the name implies, the sewer heat recovery system will extract heat
from local sewers, which will then be used to heat buildings and domestic hot
water. This innovative method is said to have significant advantages over
conventional gas or electric heat. Sewer heat will generate half the greenhouse
gas emissions of natural gas, with substantially lower levels of air-shed
pollutants.
The city investigated two sustainable heat source options: biomass and sewer
heat.
