During a flooding event,
it is important to pay close attention to the condition of your septic system.
If the system appears to be completely saturated, there is the potential that
sewage may back up in the building. It is essential to limit the use of the septic
system during this time. Closing off the drains,
especially at the lowest level, may help to reduce the damage caused if the sewage backs up into the building.
Once the water has
receded, there are a few things that homeowners should remember:
- Don't open the septic lids until the water has receded. Make sure that the systems lid(s) remain secure. Once the
water has receded, have an experienced professional check the condition of internal components (baffles,
filters) and ensure they are secure and unclogged.
- If a back up in the building has occurred, use
a proper disinfectant to clean the area.
- Before using the system, make sure the water
on the bed is lower than the water level around the house.
- If drinking water for the property comes from
a well, it is important to have the water tested before it is consumed to ensure it has not been contaminated.
- Have the system pumped (and back washed) by an experienced professional after the water has receded in
order to remove any silt and debris that may have been washed into the
system.
- Don't compact the soil over the septic bed. This may reduce the soil absorption ability to treat wastewater and
cause the system to fail (and potentially cause a back up in the building).
- Check all electrical or mechanical components
(grinder pump, effluent pump, ejector pump, etc.) to ensure the connections have
not been compromised.
- When the area is dry, repair any areas of erosion or sod damage over the septic bed to ensure an adequate cover and stability.
