Will there be odours from my Waterloo Biofilter?
A. Qualitative third-party testing confirms there will be no odours (page 76, PDF, 818KB) from your Waterloo Biofilter when properly installed and maintained. Bad sewage odours are primarily caused by chemically reduced compounds such as nitrogen and sulphur that are produced in an anaerobic environment such as the septic tank, this is normal. As it cleans the sewage, the Biofilter actually oxidizes malodorous compounds to help render them odourless. If septic odours are present on your property the most likely culprit is downdrafting from your roof’s ‘stink pipe’ vent. Ensure that this vent pipe is high enough to disperse septic tank gases properly. Very strong septic odours are often associated with high sulfur content in the groundwater (areas of gypsum, black shale, pyrite), high strength sewage created from extreme water conservation, or an unhealthy septic tank. Use JumpStart™ to rejuvenate an unhealthy septic tank and follow these steps ( PDF, 604KB) to ensure it stays that way.
