The Chehalis River basin has experienced significant flooding events in recent years, particularly affecting properties in Centralia and Chehalis. During floods, septic systems can become saturated, causing backup, system failure, and potential contamination of floodwaters.
Our technicians are specifically trained in post-flood septic recovery, including proper system assessment, tank pumping to prevent floating, and drain field rehabilitation. We work directly with Lewis County Health Department officials to ensure flooded systems are properly restored and documented according to county regulations.

The heavy clay soils common in Napavine and Winlock present unique challenges for septic drain fields, often causing slower percolation and potential system backing up during wet winter months. These soil conditions require specialized drain field designs and more frequent maintenance.
Our technicians use soil-specific approaches, including specialized drain field maintenance techniques and a properly timed pumping schedule, to maximize system efficiency in clay-rich areas. We’ve helped numerous Napavine and Winlock homeowners transform struggling systems into reliable performers despite challenging soil conditions.
