A septic system consists of two primary components: the septic tank and the leach field (also called a drainage field). The main drainage pipe from your home connects to the inlet side of the septic tank. When wastewater and waste enter the tank, solid materials and toilet paper sink to the bottom, while a layer of grease floats at the top, with water stored in the middle section. On the opposite side of the tank, an outlet pipe leads to the leach field. Water flows through this outlet pipe into the leach field lines, where it passes through a bed of rock that filters and purifies the water before it enters the ground.

Several factors determine how often your septic tank requires pumping, including the system's age, household size, tank capacity, and water usage patterns. For households without a garbage disposal, Brad's Septic & Sewer Service recommends pumping every two to three years. If your home has a garbage disposal, annual pumping is advised.

Household size represents only one consideration when establishing a pumping schedule. Even with minimal occupancy or reduced water usage from showers, toilets, sinks, and laundry, regular pumping prevents solid waste from migrating into the leach field and blocking the drainage lines. Additionally, sewage waste generates gases that accelerate the structural deterioration of your septic tank. Maintaining a pumping schedule of every two to three years extends the overall lifespan of your septic system.
