Monsoons aren’t exactly commonplace in the King County area. However, rough storms do occur every now and then. What is the impact of storms on septic systems? What can you do to keep the system from flooding?
Storms and Septic Systems: What’s the Connection?
Storms mean heavy rainfall, which can flood the soil absorption area that comprises the drain field. Once this area is saturated, the wastewater from the septic system has nowhere to go. The effluent then travels back into the plumbing system, backing up the sinks, drains, and toilets.
Prevention Before the Storm
Check the weather forecast. If you anticipate heavy rainfall, take the following measures:
- Schedule a septic system inspection. A system already near its breaking point will have a harder time dealing with a flooded drain field. We recommend an inspection even for relatively new septic system installations.
- Direct all gutters and spouts away from the drain field.
- Keep vehicles and heavy equipment off the drain field. Excess weight causes soil compaction and reduces the soil’s ability to eliminate effluent.
