If you own a home or property in British Columbia, septic maintenance is not optional. It’s your legal duty under BC’s Sewerage System Regulation. A well-maintained septic system protects your health, your neighbors, and your investment. Plus, regular maintenance helps you avoid costly repairs or legal trouble.
🛠 Why Septic Maintenance Is So Important
Septic systems don’t just manage waste—they protect drinking water and the environment. If a system fails, it can leak harmful bacteria and chemicals into the soil and water supply. That’s why the Public Health Act and BC Reg. 326/2004 require you to maintain your system.
Some key reasons to keep up with septic maintenance include:
- Preventing backups and overflows
- Extending the life of your system
- Avoiding contamination of groundwater and surface water
- Staying compliant with provincial law

What the Law Says in BC
Under Section 5 of the Sewerage System Regulation, all septic systems must be maintained according to a written plan. This plan should:
- Follow standard practice as outlined in the Sewerage System Standard Practice Manual (SPM v3)
- Be provided by an Authorized Person at installation
- Include instructions for routine care and monitoring
Failure to follow your maintenance plan could result in orders or penalties from a Health Officer. They can even take corrective action on your property if a health hazard exists.
What to Include in Your Septic Maintenance Plan
Your maintenance plan should be clear, easy to follow, and suited to your specific system. Here’s what a strong plan typically includes:
- Pump-out frequency: Usually every 3–5 years
- Effluent filter checks: Clean or replace filters regularly
- Sludge and scum monitoring: Check tank levels annually
- Field area inspection: Look for soggy patches, smells, or backups
- Record keeping: Log all maintenance and inspections

What Happens If You Don’t Maintain It?
Letting your system go unchecked is risky—and not just financially. A poorly maintained septic system can be declared a health hazard under Section 15 of the Public Health Act.
If this happens, a Health Officer may:
- Issue an order to repair or replace the system
- Inspect your property and access your records
- Take emergency action and bill you for the costs
In some cases, you could also face legal action or fines. The bottom line? Regular maintenance is always cheaper than a system failure.
