On average, an average household septic tank can last up to five years depending on the number of users at home.

When the water leaves the septic tank, it flows and stuck in the drain field. This is where the bacteria start to clean the wastewater by breaking down organic impurities. The cleaned water is then absorbed into the soil surrounding the drain field. However, this process will be stalled and hindered if the drain field has damaged. The liquid water will have no repertoire; thus it will redirect back to its location in the tank, causing the tank to overflow.
