Septic tanks after outages
During a storm, you should reduce your water use to a minimum. This can be done through taking short showers, not washing laundry, and not flushing the toilet each time it’s used for liquid waste. Each time the water is used the septic tank will continue to fill. If all the reserve storage is used, the waste pipes in your home can back-up. There is normally a one-day supply of emergency storage space available in the pump tank. Turn off the pump at the control panel.
WARNING: If the power outage caused the pump to malfunction, do not enter the pump chamber.
