There are numerous factors to consider if you need to install a new sewer line. From choosing an appropriate location to considering its impact on neighbouring homes and businesses, working with a professional with experience in this field is crucial. Sewer lines are constructed to safely and efficiently carry wastewater to a treatment facility. Designing a sewer line should be among the first projects before construction as that will helps to avoid many plumbing issues in the future. Are you planning to install a sewer line on your property? Below we prepared a guide with all the information you need to know before starting the project.

1. Measurements and Dimensions

First, it’s important to determine the elevation and depth of the pipes. The sewer line should start from the main drain and end at the house's foundation. Use a GPS or laser level to determine the elevations. You also need to estimate the slope of your trench. The standard slope should be 2% of every drop of 100 ft. This facilitates a good flow of liquids in the sewer.

2. Materials

Sewer lines are usually made of clay, plastic, or PVC. Some are made from cast iron, but those tend to be more expensive than other options. The materials you choose to use will determine the longevity of your sewer line. The pipes will be buried underground, so they need to be structurally sound and durable. Your choice of sewer lines should be based on their length, diameter and the quality of the soil in which they are buried. Ensure you consult with your plumber for more advice.

3. Installation

The installation process is a strenuous task. It will save you time if you hire professionals to install it. The first step of the installation process is digging a trench. You need to be cautious when digging the trenches. Ensure you place visual indicators around the dug area to prevent accidents. The dimensions of the trench should be twice the diameter of the sewage pipe to be used. You can also place bedding material before laying the pipe for extra support. When installing the pipes, it's advisable to start with lower-end elevations and work your way up to the higher elevation.

4. Back Fill the Trench

Before the backfill process, ensure to inspect the pipes in case of any loose connection. The backfill process involves laying several soil layers on top of the pipes. When layering the pipes, you should install warning tape over the first layer of soil. The tape alerts excavators of an underlying sewage line.

Installing a Sewer Line

Your sewer line is one of the most crucial parts of the plumbing system on your property. Overlooking the installation process may lead to a damaged or blocked system and result in costly repairs down the line. Having a well-installed sewer line guarantees a peaceful stay for you or your tenants. Hire a professional plumber with experience in sewer line installation to get the job done.
