A Guide To Installing A Sewer Pipe Line

Oct 30

The laterals are sewer pipes that connect your residence to the main sewer line or the municipal branch. This kind of pipe installation is usually carried out in a slanted trench and properly laid. Installing a sewer liner involves five major steps. Local code inspections are required for all installation details to be approved and installed by sewer pipe installation in Bridgeport.


Calculate the Altitudes

When building a sewer line, it is crucial to consider the length and depth of the pipe. A sewer pipe for domestic use runs from the foundation of a home and is also referred to as a "main drain" or "main drain" pipe. The line then descends to the point known as a tap, connecting to the city's main branch. A laser level, GPS, or traditional surveying equipment can be used to measure and place elevations.


Find the Gradient

The initial slope estimations are based on altitudes and the pipe length. The total elevation drop can be determined by subtracting the elevation at the end from the starting elevation. The slope can be determined by subdividing the drop by the pipe's overall length.


If the pipe joins with the city main at six feet, it will slope 2 feet. The slope is an 80-foot pipe run.


Two-hundred and five percent (0.025%)


In most places, the minimum slope should be 2 percent or 2 feet of descent per 100 feet of running distance. Some slightly steeper slopes are fine if they adhere to the building codes of your local area. An excessively steep slope can cause blockages since liquids flow faster than solids. A shallow slope can result in poor drainage since it decreases the velocity of liquids.


Locate the bedding, then dig out the pit


To avoid soil disturbance, the lateral sewer trench should be dug carefully. To prevent soil from shifting, the disturbed soil should be compacted. While a smaller trench is preferred in most cases, it is important to determine exactly where the pipe will be. It is necessary to construct a larger trench.


The trench must have a smooth, well-compressed bottom and a slope. To ensure that the pipe is sturdy over time, the use of bedding material, such as sand, could be deposited in the trench. Additionally, since sand is more slope-friendly than dirt, the pipe could be installed with the slope adjusted.


Install the Tube


Modern PVC sewer pipes are easily joined using gasket fittings or solvent glue. Pipes of 4 inches are the norm for domestic water lines. The municipal code determines the material for pipes and the dimensions.


Each pipe segment should be fitted with its bell (female end) in the direction of an upwards slope to decrease the risk of leaks at the joint. By city regulations, the pipe is connected to the mainline in the city. Most codes at the home end usually require one or two cleanouts so sewer augers can be used to clean the pipe.

Do the diggings


Once the sewer lateral is finished and passes the final inspection, the trench can be filled. It is common to use a layer of sand for the first layer of backfilling. This protects the pipe and fills any gaps. The trench then gets filled in by soil layers. An effort is made to ensure that the soil will not settle in the future.


Warning tape should be positioned on top of any dirt that has been compacted. The crew will be warned of any excavations in the area.
