A septic system is an underground system of collecting, treating, and disposing of wastewater from a house. Typically, these types of systems are used in more rural areas where central sewer systems that multiple homes and businesses connect to are not present. There are two major parts to a septic system: the septic tank and the drainfield. Essentially, wastewater runs from your home through a pipe into the septic tanks. The septic tank holds the water until sludge and scum are separated, and then the liquid wastewater leaves the tank and enters the drainfield. A drainfield is often located beneath a home’s yard, and the water which flows into the drainfield is slowly released into the ground, providing the ground with moisture and even nutrients it needs to help grass and other plants grow. This is possible because all of the waste that is flushed into a septic tank is collected at the bottom, allowing the water to flow through filters into the drainfield with no contaminates. If a septic system isn’t regularly cleaned, however, human waste and other particulates can get into your drain field, disallowing the water to properly drain. If left long enough, your drain field could become completely blocked, your septic tank stops working, your home plumbing starts experiencing blockups and foul odors, and the repairs to the drainfield and septic system will range in the 1000s of dollars.
