Proposed Standard Will Support Water Main Pipe Rehabilitation


A proposed ASTM International standard will be used to help rehabilitate water mains. ASTM’s committee on plastic piping systems (F17) is developing the proposed standard (WK69438). 

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.   

This effort directly relates to the United Nations Sustainable Development Goal #6 on clean water and sanitation. 

ASTM welcomes participation in the development of its standards. Become a member at The next meeting of ASTM International’s plastic piping systems committee will be Nov. 4-6, Houston, Texas, USA.
