How can residents tell if a septic system was affected?

Onsite septic systems have most of their functional components below ground and are typically more resistant to fire damage. However, it is important to inspect the aboveground electrical and plumbing system for damage to PVC piping that may have been impacted by heat. If your wastewater disposal system has been damaged, or if your system is backing up or malfunctioning, discontinue use and contact Permit Sonoma 707-565-2849 or visit:
