For many years, structural rehabilitation of mains was strictly available in the gas and sewer industries. A few years ago, Sanexen, in collaboration with the National Research Council Canada (NRC) developed a new structural liner for the rehabilitation of drinking water mains . Aqua-Pipe® is the new economical and viable alternative to the water main problems where, in the past, dig and replace was the only choice. City managers and public works departments now have a decision to make when they experience the following symptoms with their water mains:

• Loss of structural capacity (water pressure, live or dead load)

• Experience numerous pipe breaks or high rate of leakage

• Loss of important hydraulic capacity in addition to structural problems

• Experience water quality problems in addition to structural problems

Aqua-Pipe® is a structural liner that is designed and manufactured with mechanical properties exceeding all specifications and meeting drinking water requirements (Aqua-Pipe ® is certified by NSF to standard NSF/ANSI 61).

 

 

 

 

 

 

The Aqua-Pipe® solution has many advantages, such as when:

• Replacement of the old water main is not possible due to new or extensive terrestrial construction and landscaping.

• Cost is an issue: in most cases, the installation of Aqua-Pipe ® is less expensive than the open-cut replacement option.

• Complete access to driveways is a must and the closing of streets to residents as well as businesses is out of the question.

• The water main runs underneath a bridge or overpass rendering access to the main impossible.

As one can see, there are strong advantages in using the Aqua-Pipe ® system in well populated areas where water main breaks and rusty water plague the system.

With the help of its licensees, over 400,000 feet ( 125,000 meters ) of Aqua-Pipe ® have been installed over the past four years throughout Eastern Canada and the United States .
