Septic Systems After Flooding or Heavy Rain
Why saturated soil changes septic performance and the conservative steps to take after flooding.
Flooding and prolonged rain can saturate the soil a drainfield depends on. When soil cannot accept more water, septic performance can slow or back up even if the tank did not suddenly fail.
Reduce hydraulic load
Use as little water as practical while the drainfield is saturated and delay high-volume activities when possible.
Protect wet soil
Keep vehicles and heavy equipment off saturated drainfield areas because wet soil is vulnerable to compaction.
Treat backup as a health issue
Surfacing wastewater and indoor sewage backup call for local public-health guidance and qualified septic help.
Additives are not flood recovery
A tablet cannot dry saturated soil or repair displaced/damaged components.
