How Your Septic System Works
Your home septic system is a self-contained wastewater treatment system that manages water generated from your household plumbing. The system typically consists of a septic tank and a drain field. Wastewater enters your septic tank from the house through a main sewer line. Inside the septic tank, solids and liquids are separated. Heavy solids sink to the bottom and form a layer of sludge while lighter materials such as grease and oil float to the top and form a layer of scum. Anything that is not considered a solid or sludge is called effluent, the rest of the liquid in the septic tank. Effluent is filtered out of the septic tank and into the drain field through a series of perforated pipes buried in gravel-filled trenches. As it enters the drain field, it is slowly released into the soil where it’s naturally filtered and treated by the soil and microorganisms present in the soil. Treated wastewater coming from the leach field eventually re-enters your groundwater system. As the effluent is removed from the septic tank, the resulting solids and scum form more compacted layers of waste that will eventually have to be removed in order for your septic system to keep working as it should.Why Septic System Pumping Is Necessary
As the layers of solids and sludge settle in the bottom and float in the top of the septic tank, they build up to the point where they reduce the tank’s capacity to hold wastewater. As the tank fills up, effluent does not have enough time to separate and settle before leaving the tank, resulting in the discharge of untreated water into the drain field. Untreated wastewater leads to clogs, backups, and costly damage to your septic system. Pumping is necessary to keep your septic system optimized and working as it should. This process ensures that wastewater and treated water are kept separate, and your home water supply remains safe for you and your family to use.The Pumping Process
Septic system pumping is typically performed by a licensed professional who uses a large vacuum truck to remove solids and scum from the septic tank. During a pumping session, your septic professional will locate your septic tank and uncover the access port. A hose is then connected from the vacuum truck to the access port of the septic tank; a powerful vacuum is then used to suction out accumulated solids and scum from your septic tank. After your tank has been emptied, your technician will then inspect it for signs of damage, wear, and tear. Any deficiencies will then be addressed and repaired before the septic professional refills the tank with clean water to ensure proper settling of solids and effluent separation.How Often Should a Septic Tank Be Pumped?
The frequency of septic tank pumping depends on a number of factors. Larger septic tanks can hold more wastewater and solids; they will not require pumping as frequently as smaller tanks. The number of people living in your household is also a factor in how frequently your tank should be pumped. Larger families tend to use more water for daily chores, showers, cooking, and cleaning; this larger volume of water will need to be treated and addressed more frequently to keep clean water supplies safe. Certain factors, like the use of the garbage disposal and flushing of non-biodegradable materials down the toilet, can increase the amount of solid waste in the tank requiring more frequent pumping. If your system is older or hasn’t been upgraded and serviced in a while, making that first inspection and pumping appointment will be especially important to preserve the integrity of your septic system.Professional Septic System Recommendations
