Before freezing weather
HealthLinkBC advises keeping vehicles and snowmobiles off the system and discusses preserving insulating snow cover. Review site-specific frost protection and any long winter absence with the person responsible for the system’s care.

Keep roof and perimeter drainage away from the dispersal area. If water ponds over it, seek advice from an authorized person rather than choosing a drainage fix from a catalog.

Floodwater can affect the ground supporting a septic system and the safety of a private water supply. Seek qualified advice on restoration and water safety. Do not assume the system is ready to use because the water has receded.

BC requires owners to follow the maintenance plan and retain maintenance records. Keep dates, service reports, observations and recommended follow-up together. Ask the provider to clarify the service schedule for this system rather than adopting a universal pumping interval.

Never enter a septic tank. Tank atmospheres and access openings can be dangerous. Keep people away from open or damaged access points and arrange qualified service; use existing documents and safely visible external labels for product enquiries.
