Why Consider CIPP Over Traditional Methods of Rehabilitating Cast Iron, Ductile Iron or Asbestos Cement Pipe?

The overall quality and quantity of drinking water is a constant concern to municipalities across North America. This is what has motivated FER-PAL to develop innovative structural pipe lining solutions that extend the watermain’s service life for up to 100 years. 

Traditionally, watermain rehabilitation involved the labor-intensive process of excavation and replacement (open-cut). While this method may still be necessary at times, it comes with a substantial cost and poses disruptions to communities, as well as environmental challenges. What is the alternative? Cured-in-place pipe (CIPP) lining.

The CIPP Solution

FER-PAL’s CIPP lining solution offers an alternative approach, enabling the restoration of existing watermains without the need for extensive trenching. This means watermains can be rehabilitated without the drawbacks of digging long trenches, causing traffic disruptions, uprooting irreplaceable trees, and obstructing entryways to businesses.

A licensed installer of ALTRA CIPP liner, FER-PAL uses a three-step process to rehabilitate existing watermains:

Phase 1 – Preparation

An access hole is excavated to the existing watermain, which is then cleaned and flushed out.

Phase 2 – Rehabilitation

A liner is pulled into the existing waterman and cured in place.

Phase 3 – Return to Service

Each service is robotically reinstated from inside the newly rehabilitated watermain.


ALTRA, the leading product used for trenchless structural watermain rehabilitation is composed of two polyester jackets and an epoxy resin, the ALTRA CIPP liner is an AWWA Class 4 structural lining solution.

The ALTRA Advantage

  • Stops watermain breaks and leaks
  • Pulled-in-place system with wet-out of liner occurring on-site
  • Ability to line multiple 45-degree bends
  • Install new services via hot-tap with standard tapping tools
  • Reassemble with standard fittings
  • 100 year life expectancy

Rehabilitating asbestos cement pipe protects drinking water

There has been a lot of buzz recently about asbestos fibers leaching into our drinking water supply from decades-old asbestos cement pipes. A W5 investigation identified 85 communities that are still using asbestos cement pipes in water systems today. Read more.
