Septic Tank Questions, Answered

What is the purpose of a septic tank?

A septic tank is an underground wastewater treatment structure. Its primary purpose is to receive the household sewage from your plumbing system. Inside the tank, solids settle to the bottom as sludge, and lighter materials like grease and oil float to the top as scum. Bacteria within the tank begin to break down the organic waste, partially treating the wastewater before it flows to a drainfield for further purification.

How long do septic tanks usually last?

Septic tanks are designed for longevity, with many lasting between 20 to 30 years.

Proper pumping and avoiding harsh chemicals can extend the life of your septic tank considerably.

How often do septic tanks need to be emptied?

Septic tanks generally need to be emptied, or pumped, every three to five years. This frequency depends on the size of your tank and the volume of wastewater your household produces.
