Probably one of the most important reasons that you need to consider getting your septic system pumped regularly is to protect the safety of your groundwater. When your septic system is working properly, its good bacteria will partially break down the effluent before it’s released into your drainfield. Then, the soil will filter the effluent further, removing bad bacteria and viruses from it before it meets your groundwater supply. If your tank gets overfilled, the effluent won’t break down correctly, which can lead to unwanted contamination of your groundwater.
Most municipalities and county governments have enacted regulations regarding rural residential septic systems. They’ll typically require pumping every two to five years alongside an inspection by one of their licensed agents. If you live in an area that has similar regulations, you’ll want to get your system pumped to avoid unnecessary fines or worse repercussions.
A big concern when you have a home septic tank is that it can overfill. When this happens, unwanted sludge and other sewage can make their way up your main sewer line. Unfortunately, this can lead to raw sewage backing up in your toilets, tubs, sinks, and so forth. That is a problem that no one wants to ever think about dealing with.
