The Calaveras County Water District held a town hall meeting on Wednesday June 5 at Mountain Christian Fellowship near Forest Meadows to provide an overview of the Reach 1 Pipeline Replacement Project.

CCWD is replacing 5 miles of water transmission pipeline between Avery and Forest Meadows. Construction began July 8, 2019, and will continue through fall 2019 and resume in spring 2020. Project completion is expected in fall 2020. The project is necessary to replace aging infrastructure that is failing and to increase fire flows and hydrants along Highway 4. The project will cost $7.5 million and the funds are coming from the Water District’s Capital Renovation and Replacement Fund.
Construction Update: July 15-19
Crews will continue to cut down trees between Meadowview Road and Hunter Dam Road that are in the pipeline alignment (note: all trees that are being removed are within the Caltrans easement and have been approved). Crews are using pull-outs along Highway 4 as staging areas and are laying down trees that have been removed and stacks of pipe that will be installed as the project moves forward. The contractor will also work on installing culverts and pipe crossing of drainage. Traffic control will be necessary in some areas to allow crews to safely remove large trees. Expect delays of 10-15 minutes. The delays are expected to be shorter once tree-removal is complete.
This Web page will be updated weekly with new project information.
The project will replace an existing 8-inch steel water transmission pipeline installed in 1965. The pipeline is being replaced due to its poor condition and a series of failures and repairs. The new pipeline will consist of 23,000 feet of new, 12-inch pipeline and 1,300 feet of new, 8-inch diameter ductile iron water main pipeline, including pressure reducing stations, fire hydrants and air-release valves.
The alignment starts at Hunter Dam Road near Avery, continues westward along Highway 4 through Hathaway Pines and Red Apple Ranch and ends 6,300 feet west of the entrance to Forest Meadows. Other than an 1,100-ft section on U.S. Forest Service property near Hunter Dam Road, the alignment is in Caltrans right-of-way along Highway 4. Both existing and new pipelines are located primarily past edge of pavement within the south side of the right-of-way, along with an existing buried high voltage electrical line.
Given its age, poor condition and high pressure (250-psi), caution must be taken when excavating or working in close proximity to the existing active pipeline. The work will be sequenced to keep the existing pipeline operational and install the new pipeline without causing service interruptions to customers and to safeguard public health and bacteriological sterility in the water system. For portions of the alignment, the contractor must provide temporary bypass piping to maintain continuous water service in order to remove the existing steel line from the trench and then install the new pipeline. The contractor’s work is subject to encroachment permits, traffic control requirements, environmental mitigation, and numerous other permit conditions that must be performed by the Contractor during the course of work.
