Spray-in-Place Pipe Relining & Rehabilitation

Repair aging underground pipes with minimal costs and system downtime

Cleaning and repairing deteriorated water or sewer pipelines helps improve system efficiency and protects both your community and the environment. The task can be daunting and expensive especially when excavation is required.


SUEZ provides an innovative spray in place pipe rehabilitation (SIPP) process that scrubs underground pipes clean before applying an epoxy lining for in-situ pipe repair. Designed  by Warren Environmental, the 2-part component epoxy material is ANSI/NSF Standard 61 approved for potable water supply. Once cured, the epoxy lining provides long-lasting protection to your sewer or water pipes, which helps reduce the frequency of maintenance and pipe replacement. This no-dig pipe rehabilitation technology minimizes maintenance costs, and system down-time.

Our Pipe Relining Solutions
SUEZ spray-in-place pipe rehabilitation process (SIPP) is an efficient and long-lasting pipe rehabilitation solution that uses a spray nozzle attached to a state-of-the-art, computer-controlled robot to apply an internal epoxy pipe lining in-situ. No major road or sidewalk tear-ups are necessary. Once cured, the lining seals the pipe, preventing leaks and water contamination, improving flow capacity and minimizing future maintenance costs. This rehabilitation technology works on pipes made of different materials and ranging from 1 ¼ inches to 72 inches in diameter, both vertical and horizontal.

How Do SUEZ’ SIPP Technologies Work?

SUEZ’s spray in place pipe rehabilitation process consists of five steps:

  • System analysis that includes mapping, utilizing closed-circuit television (CCTV) to evaluate digitally recorded findings and then diagnose and identify a restoration plan.
  • Preparation of the pipe interior by drag scraping, power boring and/or hydro-jetting to create a clean, smooth dry surface. This is followed by a second CCTV inspection to determine if there are any leaks, infiltration, or repairs that are needed outside of the spray in place pipe scope of work.
  • Preparation for the application of the sprayed-on epoxy pipe lining.
  • Spray-on application of the epoxy lining using state-of-the-art robotic rigs that are computer-controlled for more refined application and curing.
  • Final inspection and coating analysis.

Once cured, the spray-applied epoxy pipe lining creates an internal seal that prevents leaks and helps protect against future corrosion and biological buildup in your water main. This extends the pipes’ service life, helps reduce the frequency of maintenance, and increases the flow capacity for greater system efficiency.

SIPP technology can yield an estimated cost saving of around 20 to 30% when compared to direct replacement, where you dig up the entire length of the pipe that needs attention and replace it all. Another benefit that transcends cost: the ability to minimize inconvenience to consumers by relining water pipes rather than digging them up and replacing them.

Value of SUEZ spray in place pipe rehabilitation & relining solutions:

  • EXTENDS service life of water or sewer pipelines
  • REDUCES frequency of maintenance, minimizes repair costs and system down-time
  • ENHANCES flow capacity and system efficiency
  • PREVENTS leaks and water contamination
  • PROTECTS against future corrosion and degradation, eliminates leaching of lead from soldered joints
