Cities across the nation and close to home are being impacted by the challenges associated with aging infrastructure and failing utility pipeline systems. These systems, including water, sanitary sewer, and storm sewer, are the cardiovascular system of public works and are extremely important to support life at the most basic level. When these systems fail, they often have costly and, in some cases, deadly consequences. As such, it is important that we protect and maintain these assets just like other critical pieces of infrastructure to ensure its sustainability into the future. This is where advanced trenchless technologies can save time, political capital, and money.

Replacing and rehabilitating public utilities can be challenging. Oftentimes roadway improvements, traffic detours, and general inconvenience to neighborhoods can be costly and taxing on project stakeholders. While various methods of trenchless rehabilitation exist to ease those headaches, pressure pipe rehabilitation remains a costly, time-consuming endeavor compared to new technology like gravity pipe systems.

• Average Installation Length: 2,500 Feet (8,000 LF Max)
• Qualifying Pipe Installation Diameters: 2 in. to 54 in.
• Structural Integrity: Class 3 or Class 4 Fully Structural Rehabilitation applications
• Drinking Water Approval: NSF 61 Approved 
• Price: Up to 50 percent cost savings when compared to pressure rated CIPP lining

While there is no one-size-fits-all solution to trenchless pipeline rehabilitation projects, Tight-Fit Slip-lining offers many benefits to stakeholders with pressure pipe rehabilitation needs. It is important to understand the tools and technologies associated with the trenchless industry, so you continue to build sustainable, cost-effective, and publicly accepted projects. Service connection needs, internal pressure requirements, temporary conveyance, existing pipe alignment, and future capacity needs all play a role in trenchless pipeline installation method selection.
