Why Category 3 Hits Lake San Marcos Hard
The pattern in Lake San Marcos 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.
Lake San Marcos experiences mild, wet winters and dry summers, which can lead to prolonged saturation of soil and increased risk of septic system failure. Atmospheric river events further exacerbate the risk of black water contamination.

Atmospheric river events further exacerbate the risk of black water contamination. 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.
