Potential Solutions: Water treatment plant; replace mains; rehab tank-REPLACE 11 MILES OF TRUNK LINE, DEVELOP RELIABLE WATER SOURCE, UPGRADE PUMP STATION AND INSTALL STORAGE TANK FOR FIRE FLOW. OTHER - DESIGN AND CONSTRUCTION-The proposed project will replace and upgrade existing water pipelines and will be constructed in existing designated streets, alleys and dedicated rights-of-way. No acquisition of lands will be required.Proposed New ConstructionThe water system consists of upgrading from the existing 2-inch mains to 4-inch mains. The initial estimate includes 17,800 linear feet of 4-inch pipe, 65 re-connections, 9-gate valves, and miscellaneous items to complete the project.Since the proposed improvements will replace and upgrade existing pipes, the existing users should not increase the existing water consumption. Therefore, the system capacity should remain the same.Proposed RehabilitationThe water system proposes to have approximately 10,000 linear feet of the existing 2-inch water line mains removed.Nature and Level of ServiceThe District provides water service to approximately 400 residential and 40 commercial connections. The water system project will enhance the District=s water system within its boundaries.Coordination with Other Service ProvidersThe District is the only water system in the area. The I-5 and Highway 46 commercial water connections are also serviced by the Districts water system. There may be a need to coordinate with Kern County for the drainage piping in the community.-The proposed work on the 2MG will consist of draining the tank, replacing the existing series of interior roofing wood column supports with steel columns, sandblasting the interior tank wall surface, repair any suspect areas, re-coat the steel wall surface and paint the new steel columns. In addition, the work would include re-filling the tank, disinfecting the filled tank and testing the water for chlorine residual prior to placing the tank back into service. Lastly, the construction work will require that the 2MG storage tank be out of service for several weeks, which will require around the clock monitoring of the well, and the water distribution system along with a smaller interim tank for use while the larger is empty.Proposed Rehabilitation:The actual rehabilitation work of this project includes the sandblasting of the interior wall surfaces and re-coating. The project will include needed repairs as determined by the Engineer once the interior surfaces are sandblasted. However, the plans will include a minimum amount of repairs within the bid package. An interim tank will be needed during the time repairs are being made.-Project Location:Site 1: Project will be located at the current Arsenic Removal Treatment Facility. Site is located at the northeast corner of Gun Club Road and McCombs Avenue in Kern County. The parcels associated with this site are APN 059-160-19 and APN 059-160-18. Site 2: The Chemical Treatment for corrosion prevention is to be located at the 2.5 MG storage tank site located on the northeast corner of Highway 46 and Brown Material Road. The parcel associated with this part of the project is APN 058-180-13.Site 3: The pipe to be replaced will cross Highway 46 near the intersection of Highway 46 and the on-ramp to Interstate 5. The parcel associated with this site is APN 069-171-02.Site 4: The pipe to be replaced will cross Highway 46 north of the Lost Hills Elementary School. The parcel associated with this site is APN 058-131-22.Site 5: The pipe to be replaced crosses Interstate 5 north of Highway 46. The parcels associated with this site are APN 058-330-04, 058-330-03, and 058-33-06.New ConstructionSite 1: Installation of two sludge beds with three bays each at the existing Arsenic Removal Facility. Site 2: A Chemical Addition facility will be constructed for the 2.5 MG water tank.Rehabilitation: Replacement of two sections of pipe are needed at Sites 3 and 4 to improve drinking water conditions. The original pipes are 8” steel and are to be replaced by a method of jacking and boring using a 12" steel.Site 3: The pipe section to be replaced is approximately 135 feet in length. Site 4: The pipe section to be replaced is approximately 100 feet in length.Site 5: The pipe section to be replaced is approximately 250 feet in length.The project can be separated into three phases: planning, design, and construction.Consultants will complete design with direction from LHUD. LHUD Board of Directors with the assistance of Consultants will be the Agency to implement the Project. The Board and Consultants have implemented projects of this magnitude in the past. Alternative sites: No other locations were considered due to: Site 1: This location is best to eliminate unnecessary rerouting of piping and acquisition of new District owned land. Site 2: The chemical addition for corrosion prevention is best placed at the site of the existing tank to keep pipe routing changes to a minimum.Site 3: Pipe replacement must be performed at the sites indicated to prevent rerouting of the piping.Site 4: Pipe replacement must be performed at the sites indicated to prevent rerouting of the piping. Site 5: Pipe replacement must be performed at the sites indicated to prevent rerouting of the piping.
