Diameter Sewer Rehabilitation Program -
Phase I and II
Phoenix,
Arizona
The City of Phoenix
is rehabilitating small diameter sanitary
sewers, some of which are 90 to 100 years
old, utilizing trenchless construction technologies.
Dibble provided Quality Control/Quality Assurance
monitoring during the pipe rehabilitation
process. The rehabilitation method selected
was Cured-In-Place Pipe (CIPP) using Integral
Lining System (ILS) along with the conventional
inversion method for pipeline lining. Dibble
developed bid documents containing technical
specifications consistent with current industry
standards. The rehabilitation program for
8-inch through 14-inch diameter sanitary sewers
includes 70,000 linear feet per year.
