If your land and septic system are ever flooded, follow this advice:

• Do not use your sinks and toilets if the soil around your home and septic system is saturated and flooded. Your septic system will not work.
• Plug all drains in the basement and drastically reduce water use until the system has time to recover.
• If you clean up flood waters inside your home or basement, do not dump the water in your sink or toilet.
• Do not open the septic tank or have it pumped it out while the soil is still saturated.
