Safety screens are a vital component to making your septic tank safe BUT only if they are installed properly every. single. time. Don't just secure a few screws and call it done.

✅ Use stainless steel screws whenever possible to resist corrosion and extend service life.

✅ Install a screw in every available hole. Those extra fasteners help distribute load evenly, reduce vibration, prevent warping, and keep screens properly seated over time.

A screen is only as effective as its installation. Missing screws can create weak points that allow movement, premature wear, and costly maintenance issues down the road, not to mention safety!

Bottom line: Take the extra minute. Use stainless hardware and screw down every hole.

❄️ Homeowner Hint: Mark Your Septic System Before Snowfall

If you hire a snow removal service — or even clear your own driveway — now’s the time to mark your septic tank and drain field with visible stakes or flags. Once the snow hits, it’s easy to lose track of where your system is, and heavy equipment driving over it can cause costly damage.

A few minutes now can save you thousands later. For more tips visit our Linktree!

CAN YOU FIND THE SYSTEM YOU INSTALLED 20 YEARS AGO?

Maybe.

But should finding it depend on someone's memory?

As properties change hands, systems are altered and landscaping evolves, knowing where buried components are located becomes increasingly important.

That's why detection and documentation deserve more attention during installation—not 20 years later when someone needs to dig.

Build it. Document it. Find it.

That's good lifecycle management.

OOWA's new Means of Detection Guidance Document looks at OBC detection requirements and practical approaches including tracer wire, magnetic markers and other locating methods.

What detection method are you using in the field?

Homeowner Hint

As temperatures drop and outdoor activities move onto frozen surfaces, avoid building ice rinks or piling heavy snow directly over septic tanks and drainfields. Ice rinks and compacted snow can damage underground components, block maintenance access, and shorten the life of your system.

OOWA submitted comments on proposed 2026 Ontario Building Code changes relating to Combined Treatment and Dispersal Systems, after convening a task group representing different perspectives within the onsite wastewater industry.

Technology doesn't wait for regulation.

New treatment approaches continue to emerge.

The challenge?

Making sure codes, standards, guidance and professional practices evolve alongside them.

Innovation needs a regulatory pathway.

That's where industry engagement matters.
