Southern Vermont Septic Guide: How Your Septic System Works

If you don’t rely on the municipal waste management system to get rid of your wastewater, chances are you have a septic tank in your backyard. Your septic tank sifts through the organic waste, and separates the water from the solid matter, allowing it to drain effectively into the drain field. The septic tank experts at HB Energy are committed to informing their customers about how their home systems work, so that they have the tools necessary to recognize major problems before they cause serious malfunction. While it’s not always possible to prevent repairs, a little bit of know-how goes a long way. For any septic tank problems in Southern Vermont, call HB Energy Solutions today!

Your septic tank is a watertight box buried in your yard that is usually made out of concrete or fiberglass. It typically holds about 1000 gallons, but its size depends upon the size of your home and your plumbing needs. Your sewer and drains gang together into your sewer main and flow into your tank. This new water displaces the old. Once there, there are three different layers that form inside: decomposing matter floating at the top of the tank (scum), mostly solid matter collected on the bottom (sludge), and relatively clear water in the middle of the two, which overflows into your drain field. The decomposition process takes the scum and separates it into solid matter and water.

The entire system is passive, meaning that it is powered only by gravity and the design of the system and materials themselves. The drain field, also known as the soil absorption system, is a trench with perforated piping overlaid with gravel to disperse the water. The septic tank requires a periodical removal service, which pumps the solid matter out of the septic tank to avoid overflows and promote efficient sewerage. The frequency of the septic pumping depends upon tank size, condition, and usage.

We hope that answers some of your questions about how a septic tank works. For more information, or to schedule septic tank maintenance in Southern Vermont, call HB Energy Solutions.
