CIPP Pressure-Pipe Lining

Time. Money. Water.


Water and wastewater systems both rely on pressurized pipes for a variety of uses.  And when pipes are pressurized, they need to be able to stand up to both internal and external forces.  That’s why SAK uses special types of CIPP lining to renew pressurized water and wastewater pressure pipes ranging from 6 inches to 48 inches in diameter.  


The American Society of Civil Engineers estimates that 6 billion gallons of fresh-treated drinking water are lost every day due to old, leaky pipes and water mains. That’s the kind of waste our cities and our environment can’t afford.  SAK’s CIPP Pressure-Pipe Lining, which is NSF-approved to ANSI 61, is a safe, sturdy and dependable solution for all types of potable water lines as well as water mains. 


Our sewer systems are critical to safeguarding community health and natural resources. While gravity pipes are used in most sanitary pipeline, pressurized force mains often are used to transport wastewater efficiently to treatment plants. With the added protection against pipe deterioration, SAK’s CIPP Pressure-Pipe Lining is a smart solution for renewing sanitary force mains, to protect them from pipe deterioration and failure.

      • Efficient: Lower your maintenance costs. Raise pressure and flow capacity. Regain structural capacity. And resist corrosion. SAK’s strong, smooth “pipe-within-a-pipe” makes your system more efficient.
      • Accessible: SAK’s CIPP Pressure-Pipe Lining’s design allows end-to-end installation in hard-to-reach locations under bridges and roadways, along waterways, through rough terrain, and in urban landscapes and under historic areas with minimal surface disruption.
      • Community-Friendly: Safer and faster than traditional open-cut methods, installation requires minimal, if any, excavation. So residents experience fewer disruptions like traffic detours. And everyone has fewer complaints.
      • Affordable: Generally costing less up front than open-trench replacement, CIPP also saves money in the long run by preventing main breaks, reducing treatment and pumping costs, and minimizing the need for future repairs.


    Using a CIPP process, SAK installs pressure-pipe liner into existing pressure pipes from 6 to 48 inches in diameter. The new liner is cured with steam or hot water, setting the resins and sealing this “pipe-within-a-pipe.” 

    SAK’s CIPP Pressure-Pipe Lining is a high quality, glass-fiber reinforced liner designed to fit the specific application requirements.  The glass-fiber reinforcement provides the pipe liner with self-supporting properties which allow it to withstand pressures exerted both internally and externally.  

    For drinking water applications, SAK’s pressure-pipe liner uses potable-water-approved resins, meets all designated requirements and is certified by the National Sanitation Foundation to NSF/ANSI 61.

    The liner installation is, for the most part, trenchless, allowing communities to avoid the high cost, hassle, and risk of open-trench construction in populated or challenging areas. Designed for pipes from 6 to 48 inches in diameter, and individual pipe lengths of up to 800 feet, SAK’s CIPP Pressure-Pipe Liner is a smart solution for many pressurized water and wastewater system rehabilitation needs.  


    When it comes to aging water and wastewater infrastructure, the challenges are environmental as well as economic. By preventing and fixing leaks, SAK’s CIPP Pressure-Pipe Lining prevents the loss of millions of gallons of drinking water and potential contamination of the environment from sewer-line failures.

    SAK’s trenchless technology keeps the work below ground, preserving landscapes and natural resources and eliminating the need to rebuild roads, parking lots, or other structures. And, environmental studies suggest that no-dig technology can lower greenhouse gas emissions dramatically compared to traditional dig-and-replace methods.1   Whatever your situation, SAK will work with you to protect your community’s natural and financial resources.
