Owner’s safety

To reduce risks to yourself and to others …


  • leftsafetyDo know the location of all access lids and don’t bury them or build structures on the top, including sidewalks or driveways.
  • Ensure lids for tanks or other components are in good condition. Lids to tanks must be secure and tamper resistant.
  • Prevent children and pets from tampering with system access lids and other components.
  • Be aware that exposure to sewage poses health risks. Always take measures to avoid contact, and be especially mindful of the risk if the system malfunctions and causes sewage flood of the house or causes wastewater to surface outdoors.
  • Follow all safety precautions included within the Operation & Maintenance Plan for your system. For systems built after May 31st, 2005 (new Regulation), the ROWP Planner who designed and certified the system will provide you with an Operation & Maintenance Plan. For pre 2005 systems, a ROWP Maintenance Provider (or Planner) can provide advice regarding proper use, maintenance and safety … and can provide a simple Operation and Maintenance document.


  • Do not attempt to carry out any system maintenance or modifications yourself. It can result in damage to components, cause a malfunction, and possibly create a health hazard.
  • Do not allow non-ROWPs or non-Professionals to tamper with or modify the system.
  • Do not open, adjust, modify or replace any of the electrical components unless directed by a ROWP.
  • Many systems include electrically powered components, such as effluent pumps, air blowers, high level alarms and control panels. If septic tanks, treatment plants or pump chambers are flooded, there can be a risk of electrocution if you make contact with any hardware. Similarly, the ground near the components can be energized if flooded. Be aware of the hazard. Don’t approach. Disconnect the electrical service breaker or other means to ensure safety. Get qualified help.
  • Never climb into, or even put your head into, any portion of the system. Toxic gasses, which are often colourless and odourless, can cause dizziness, shortness of breath, fainting, respiratory damage and even death. There are also other dangers which only trained and experienced persons will understand how to handle safely.
