Why Category 3 Hits Wollochet Hard
The pattern in Wollochet is consistent. sewer lateral collapse during atmospheric river rainfall events drives most of the emergency restoration calls we get. A close second is hillside septic system failure during saturated soil conditions.
Wollochet's mild, wet climate increases the risk of black water contamination due to frequent rainfall and saturated soils, which can lead to septic system failures and sewer lateral collapses
Wollochet's mild, wet climate increases the risk of black water contamination due to frequent rainfall and saturated soils, which can lead to septic system failures and sewer lateral collapses The dominant local driver is sewer lateral collapse during atmospheric river rainfall events, with hillside septic system failure during saturated soil conditions showing up as the next most common cause. Damage builds in stages. Spread. Absorption. Microbial growth. Structural compromise. Every stage you pass through adds to the final bill.
