Septic systems are made up of two main parts: the septic tank and the drain field. While much focus is typically geared toward the septic tank (i.e., how often you need to have it pumped, what you can safely flush down the toilet, etc.), there are important things that you should know about your drain field. As a significant component of your septic system, your drain field needs proper care to avoid disruptive problems, harm the environment, and extend its life expectancy.

Below are some FAQs to help you familiarize yourself with your drain field:

What is a drain field?
A drain field is an underground area of a system of pipes that slopes downward. Wastewater slowly seeps through sand and gravel into the ground, where naturally found bacteria then treat it. A drain field acts as a natural filter for wastewater. It is vital that you know the location of your drain field.

What is a drain field’s life expectancy?
Typically, a properly designed, installed, and maintained drain field should last at least 25-30 years or more.

Are there specific hazards to avoid with a drain field?
Yes! You should never drive on or park heavy vehicles over your drain field. Avoid paving or building on top of your drain field. You want to stick to simple grass as yard covering to prevent deep roots from trees and large shrubs from interfering with the drain field. Grass helps remove water and nutrients from the soil, works to inhibit soil erosion, and also naturally filters wastewater.

How can I know if my drain field needs repair?
The most obvious sign of drain field failure is surfacing seepage. If you notice soggy soil, pools of standing water, or a foul smell coming from the area of your drain field, you need to call in the professionals.

Should I have my drain field inspected?
Yes! Just as your septic tank needs to be pumped and inspected every 2-3 years, your drain field also needs to be professionally inspected. It is best to schedule both the pumping and all septic system inspections at the same time for convenience.
