Depending on where you live, there may be local ordinances that state how often you’ll need to have your septic tank undergo pumping and inspection services. They intend to help protect the integrity of the area’s groundwater supply. If you fail to get your tank pumped, your local municipality can issue you a fine.
Another great reason to get regular pumping service is that it will go a long way in preventing a sewage backup in your home. Whenever your tank gets overfilled with scum and sludge, it can start to back up in your main sewer line. If left too long, this will lead to raw sewage backing up into your toilets, drains, and other plumbing fixtures.
It’s important to remember that your septic tank is the first step in your wastewater’s journey toward cleansing before it rejoins your groundwater supply. When working correctly, your tank will partially break down the effluent before it seeps out into your drainfield. Once the effluent is in your drain field, the soil will work to naturally filter it before it reaches your groundwater. If your tank gets overfilled, this effluent will seep out before it has been partially broken down. Unfortunately, your soil is unlikely to do all the filtering that is necessary to remove harmful contaminants before they reach the groundwater. This can cause contamination and render your well system unsafe.
