TATEMENT ON THE SUBJECT: The purpose of Capital Improvement Project (CIP) Nos. 8244 and 8317, the Sanitation Manhole Rehabilitation Project, is to rehabilitate sewer manholes by injecting grout into the surrounding soil and applying an epoxy lining to the interior surfaces to seal cracks and joints. The project will also repair the channels and benches within four manholes to restore proper flow characteristics and structural integrity. These improvements reduce rainwater and groundwater infiltration into the sewer system, preventing unnecessary increases in wastewater flows that must be conveyed and treated at downstream wastewater treatment facilities.
The pr
oject will rehabilitate 20 sewer manholes ranging in depth from approximately 7 to 21 feet, requiring a total of about 254 vertical feet of epoxy lining. In addition, four manholes will receive channel and/or bench repairs. As part of the quality assurance program, holiday testing will be performed on each rehabilitated manhole to identify microscopic pinholes, voids, or thin areas in the epoxy coating and verify the integrity of the liner system. The work is located throughout the Vista and Buena sewer service areas.
S
ewer manhole rehabilitation is a specialized construction discipline that includes standardized methods and practices which provides Vista the ability to contract the work through a cooperative purchase agreement. The City of Vista is authorized under Vista Municipal Code Section 3.08.060.C, to participate in cooperative purchasing plans, programs, or services. Vortex Services, LLC (Vortex) is a specialty utilities trenchless contractor who is a member of the Houston Galveston Area Council (HGAC) Cooperative Agreement that awarded a contract for these services under a competitive bid.
