How Septic Systems Work

A septic system is a complex network of components that work together to treat and dispose of wastewater from your home or farm. It begins with the toilet, where waste and water flow into a plumbing line and into the septic tank. Inside the tank, solids and liquids separate into three distinct layers: the scum layer, liquid layer, and sludge layer. The clear water exits the tank through an outlet baffle and is dispersed into the drainfield, where it is absorbed into the ground. Regular pumping and maintenance are essential to prevent the buildup of solids and ensure the system continues to function properly.
