Background/Discussion: |
The Public Works and Utilities Department administers an ongoing Wastewater Sewer Assessment Program to evaluate, prioritize, and repair deteriorated sewer pipes and manholes within the City’s collection system. As part of this program, approximately 4,350 linear feet of 27-inch-diameter sanitary sewer pipe and 13 existing sewer manholes along SW Jacaranda Parkway, north of Ocotillo Road, require rehabilitation. The sewer infrastructure in this area is approximately 35 years old. The method of sewer pipeline rehabilitation will be Cured-In-Place-Pipe (CIPP), which is an industry standard method to rehabilitate pipeline in place with no excavation of the roadway necessary. The CIPP method does, however, require a full sewer flow bypass using pumps and temporary piping laid on the ground surface. The existing sewer manholes accessed for this work will also be repaired. Additionally, approximately 1,150 linear feet of 12-inch and 8-inch diameter sanitary sewer pipe in various areas in the residential subdivision will be rehabilitated or replaced. The project scope of work consists of pre-construction assistance, construction management, construction inspection, specialty inspections, and materials testing. The contract completion time is 120 calendar days following Notice to Proceed. A related Construction Contract with B & F Contracting, Inc., for the Jacaranda Parkway Sewer Rehabilitation, is also scheduled for this City Council meeting. A related Construction Contract with B & F Contracting, Inc., for the Ocotillo Small Diameter Sewer Rehabilitation, is also scheduled for this City Council meeting. |
