Proposed Standard to Support Water Main Pipe Rehabilitation

ASTM International said its committee on plastic pipe systems is developing a proposed standard to be used in the rehabilitation of water mains.

According to ASTM International member George Gerz, the new standard will be used for replacing old and failing distribution water main pipes.

The technology described in the proposed standard is applied by taking a new deformed U or C shaped HDPE pipe and inserting it into
an existing failing water main and expanding it with steam and air pressure back to its round shape, creating a new structural pipe-within-a-pipe. This allows for hundreds of feet to be installed in an application, creating a jointless and leak-free pipeline.

Engineers, cities, water utilities, and inspection organizations will be the main users of the proposed standard.

ASTM International integrates consensus standards developed with its international membership of volunteer technical experts. The organization welcomes participation in the development of its standards.
