Septic Systems
After the Flood
If you have a home septic system, avoid using the sewage system until water in the soil absorption field is lower than the water level around the house. Proper clean-up depends on the types of chemicals in the wastewater. Remember, whenever the water table is high or your sewage system is threatened by flooding there is a risk that sewage will back up into your home. The only way to prevent this backup is to relieve pressure on the system by using it less.
