TAKE STEPS NOW TO PROTECT YOUR SEPTIC SYSTEM FROM FREEZINGWritten by Valerie Prax, University <strong>of</strong> Minnesota ExtensionCommon reasons septic systems freeze are a lack <strong>of</strong> snow cover and cold temperatures, combined withconstruction or “use” issues. These can include a waterlogged system, cold air entering the system,compacted soil or lack <strong>of</strong> plant cover. Others include irregular use <strong>of</strong> the system, leaking plumbingfixtures or a pipe that does not have the proper change <strong>of</strong> elevation.If the soil over a pipe is compacted, the elevation <strong>of</strong> the pipe may shift, causing a loss <strong>of</strong> gravity flow. Thisresults in water left standing in pipes, which can freeze easily. If your system has frozen, you shouldcontact a pr<strong>of</strong>essional pumper or installer.Here are some precautions:• Stop mowing the grass over the drainfield in early fall. Let it grow stronger to trap more snow.• Add a layer <strong>of</strong> mulch (8-12) inches over the pipes, tank, and soil treatment area to provide insulation. Amulch <strong>of</strong> loose hay or straw works well, as do leaves. The key is to keep it loose to form air pockets,which act as the insulators. This is particularly important if your system is new, and vegetation has notbeen well established.• Don’t leave water running all the time to prevent freezing. A slow trickle could freeze, while a steadystream could overload the system.• Use normal amounts <strong>of</strong> water, the warmer the better. Spread out your laundry schedule to onewarm/hot load per day, year around.• Don’t add antifreeze to system.• If you plan to be gone for more than a day ortwo, plan accordingly. Have someone visit anduse water regularly. If you are to be gone for anextended period (weeks or months), pumpingthe tank before you leave might be the bestoption.• Reroute the drip from your furnace. This slowdrip can freeze in the pipes. Reroute this cleanwater into the sump or a bucket.• Fix any leaky plumbing. The small trickles <strong>of</strong>water going into the system can freeze as thin icelayers within pipes and eventually close them.• Keep all vehicles (including ATV’s andsnowmobiles) and high-traffic people activities<strong>of</strong>f the system, all year.• Make sure all risers, inspection pipes andmanholes have tight covers. Adding insulation isa good idea. Check for any cracks in the covers inthe fall.• Keep an eye on your system.
