What Makes Tualatin See Category 3 Events
Living in Tualatin means dealing with sewer lateral collapse during atmospheric river rainfall events sooner or later. A close second is hillside septic system failure during saturated soil conditions. The good news: water damage is fully recoverable when you catch it fast and bring in certified technicians.
Tualatin's mild, wet climate increases the risk of black water contamination, especially during heavy rainfall events and when soil becomes saturated. The area's proximity to rivers and hillsides contributes to potential septic and sewer system failures.
Most category 3 black water cleanup calls in Tualatin come from sewer lateral collapse during atmospheric river rainfall events. Running a close second is hillside septic system failure during saturated soil conditions. Once water sits unaddressed past 24 to 48 hours, microbial growth starts and the job gets a lot more expensive.
