Odours
When the Tricel Puraflo system is correctly installed and operated there should be no strong odour
in the area adjacent to the system. The presence of a strong odour would indicate that the plant is
not working effectively.
Note:
Before taking any corrective action, always positively identify the real source of the odour. Check
if the odour is coming from another outside source such as a storm drain. All wastewater
treatment plants vent gases back through soil pipe and out roof vents. Improperly installed roof
vents can cause odour problems. Traps in drains prevent odours from entering the home. To
function they must contain water and be sealed correctly.
