Lateral Service Line Inspection and Sealing


The Environmental Protection Agency (EPA) estimates that of the 75 million private laterals in the United States, 80% of them are failing and inneed of repair. These private lateral sewer lines account for 75% of the infiltration of ground water into the nation’s main sewer lines. In addition, there are at least 40,000 sanitary sewer overflow (SSO's) each year. Both wastewater collection systems and treatment facilities are reaching or exceeding their capacities. These leaking laterals cause treatment plants to treat a higher-than-anticipated volume of water, resulting in higher treatment costs for the sanitary district, and higher customer fees.

Eliminating the extra cost of treating this infiltration will more than compensate for the investment needed to inspect and repair laterals.

Studies have shown that service laterals are often a source of significant infiltration, and that most infiltration into these lines occurs with a few feet of the main. The two primary reasons for this are that, except for the last few feet, all service lines are usually above the water table, and groundwater flows easily in the backfill of a mainline because of the French drain effect.

When inspecting from the mainline, we employ special lateral launch CCTV cameras with self-leveling heads that allow the operator and viewer to always know what part of the lateral is being viewed. Each head also features a built-in Sonde, a device that allows for precise above ground location of observations made within the lateral line.

When inspecting lateral service lines from cleanouts, specially designed miniature cameras and equipment are used that enable our technicians to inspect the laterals and assess their condition.

All lateral cleaning is performed from the mainline. Using the lateral launcher, the operator guides a ½ inch hose and nozzle into the lateral connection form the mainline. Winched in tandem with a CCTV camera, a motor is used to rotate the guiding arm and nozzle into the lateral connection. The hose is propelled through the lateral – cleaning and cutting roots.

Our Lateral Service Line Inspection and GPS Location services can be used in the prevention of highly dangerous utility crossbores during directional drilling (HDD) utility installations. By accurately locating and mapping existing sewer laterals and mains in the pre-construction phase before HDD installations, crossbores from other utilities (such as natural gas and telecom) can be avoided. By inspecting the existing sewer laterals and mains in areas where HDD utility installations have taken place in the past, exisiting crossbores can be safely located and identified for immediate removal. Our technicians can then use GPS and GIS mapping software to accurately locate and map sewer lateral locations for quick retrieval and review.

Our technicians use wireless, handheld GPS mapping devices to precisely locate structures and collect accurate GPS coordinates which are then transmitted seamlessly to our inspection software.

our advantages

Industry Leading Innovations

From the beginning, Carylon companies have thrived on the notion of innovation. They invented the first continuous rod, truck-mounted power rodder for cleaning sewers, developed the use of closed-circuit television for sewer line inspections, and pioneered the internal sealing of leaking sewers using pressure chemical grouting.

24/7/365 Response When Needed

Carylon companies were among the first to provide privatized disaster response; giving top priority to requests for assistance following any natural or man-made disaster. Our vast resource of men, equipment and experience have helped many disaster-stricken communities restore normalcy to the lives of their residents in the shortest time possible.

Our Unmatched Guarantee

Whether your project calls for the use of one man and one piece of equipment, or multi-disciplinary crews and a fleet of specialized equipment, we can do the job, and do it right. And, we don't just say we can - we guarantee it. All work is backed by a guarantee that is unmatched in the industry.
