Small Diameter Sanitary
Sewer
Rehabilitation - Phase II
Phoenix, Arizona
The City of Phoenix rehabilitated small diameter sanitary
sewers utilizing trenchless construction technologies
and technical specifications developed by Dibble. The
rehabilitation method selected by the contractor was
Cured-In-Place Pipe installed utilizing both the Inversion
and Integral Lining System method. Dibble teamed with
Oridian Construction Services (a Dibble company) to
provide management and field inspection services to
the City. Our National Association of Sanitary Sewer
Companies (NASSCO) certified engineers provided Quality
Assurance/Quality Control monitoring during liner installation.
The 2005 construction budget for the rehabilitation
of approximately 70,000 linear feet of 8-inch through
14-inch diameter sanitary sewers was $3 million.
