Sewer Main Contractors

Sewer main contractors perform a myriad of jobs related to private and public sewer systems. Due to the fact that sewer pipes can cause substantial damage if improperly installed or accidentally damaged, contractors undergo substantial training prior to working at construction sites.

Any time a person hires sewer main contractors they need to make certain that contractors are licensed, certified, and hold required work permits and insurance coverage. Additionally, it's important to work with experienced contractors that are familiar with the specific type of installation processes.

The majority of wet utility construction work requires contractors to utilize subsurface utility engineering. SUE, in a nutshell, is private utility locating and vacuum utility potholing and comprises different types of equipment to identify subsurface pipes and utility systems.

Advanced technology helps contractors avoid damaging previously installed pipes that could result in workplace accidents or broken sewer pipeline. This technology delivers contractors with 3-D maps of installed pipes. SUE is used with new pipeline construction projects, as well as when contractors are repairing or replacing water mains and sewer pipe.

Pipeline that is installed in heavily populated areas, such as Beverly Hills, CA where Kana Pipeline conducted a significantly large portion of SUE work for the construction of a new underground parking garage located directly in front and below of Beverly Hills City Hall, is made up of intricate network systems that are necessary for transporting untreated sewage to treatment facility plants. These systems have to be maintained on a regular basis to make certain there are no cracks or leaks that could result in exposing residents to health risks associated with contaminated water.

One of the most basic, yet important, elements of sewer systems is sewer manholes. In essence, sewer manholes are a relief valve that allows gases that accumulate in sewer pipes to be released into the atmosphere. Furthermore, manholes provide access to subsurface pipes so that workers can make repairs and perform routine maintenance.

Every sewer system makes use of sewer laterals, trunk pipes, and branch pipes. City sewer lines also require interceptors that are attached to trunk lines so the pipeline network can be expanded throughout the community.

Almost all sewer systems make use of gravitational pull to transport untreated sewage downhill. In regions that are at or below sea level, additional steps have to be taken to elevate the land. In most cases, contractors install lift stations along the pipeline to artificially increase the elevation.

Lift stations are frequently used along the coastline and in low-lying areas such as New Orleans. When systems are powered by lift stations, wastewater is transported through a series of pipes to sewer treatment plants.

Treatment plants filter raw sewage and wastewater using a variety of treatment and filtration processes. Some of these treatments begin while the water is being conveyed through the pipes. All sewer pipelines that dispose of environmental waste are regulated by the EPA and must include oil and water separators.

Designing, installing, repairing, and maintaining sewer mains demands precise planning to ensure toxins are not released into the environment. Every element of the system has to be synchronized to ensure sewage is safely transported to treatment facilities.
