Before you start digging, you should know sewer lines are required to be buried within certain specifications and it’s your responsibility to find out what these specifications are. If you’re thinking about the appropriate depth of sewer line, then you’ve come to the right place! In this post we’re going to consider how deep a main sewer line should be buried underground.
First and foremost, you should understand that sewer lines are simply the intestinal systems of a house or property. Their primary function is to totally remove waste water and other waste matter from your drains, toilet, shower, dishwasher as well as the exterior faucets. With this in mind, we can then move to our main concern which is the sewer line depth. In a world that’s perfect, you’d be allowed to to just dig your home’s sewer line deep enough to cover it with a thin layer of sod. However, if you happen to reside in an environment with deep running cold, this inclement weather may just freeze up your waste right in the pipe due to the fact that it’s placed too close to the surface where there’s not enough warmth. This could also extend to other harsh weather conditions such as heavy wind and hurricanes which are able to tear out ground deep down and even more so, if it were to pull up trees that are close by with deep roots. Hence, the need to get the appropriate depth of sewer lines right.
Sewer lines depth can vary greatly - they can be as shallow as 12 to 30 and can be as deep as 6+ feet. This is often determined by the climate.
