This section onlyapplies to force mains with an operating pressure below 200 pounds per square inch(psi). Water does not allow HDPE pipe for gravity sewer installed by open Water allows HDPE pipe for sewer rehabilitation projects installed by pipebursting.

2 HDPE specifications for pipe bursting are located in Chapter XX, SanitarySewer Rehabilitation Specifications, of the Charlotte Water Design to Chapter XVII of the Charlotte Water Design Manual for force main standards cited in this specification refer to the current referencestandard published at the time of the latest revision date logged at the end of thisSpecification, unless a date is specifically the event of a conflict, the most stringent requirements prevail.
