On Wednesday September 11, 2019, Mozingo Construction, Inc., informed the Calaveras County Water District (CCWD) that it was stopping work on the Reach 1 Pipeline Replacement Project for the remainder of this construction season. Mozingo started demobilizing from the project that same day and has reallocated resources away from the Reach 1 Project in order…
CCWD is replacing about 5 miles of water transmission pipeline between Avery and Forest Meadows. Construction began on July 8, 2019, and will continue through fall 2019. The project will stop this winter during poor weather and resume in spring 2020 with completion expected by 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 District’s Water Capital Renovation and Replacement Fund.
Construction Update: September 9 – 13
On weekdays, one-way traffic control starts at 6 a.m. and ends no later than 6 p.m. (3 p.m. on Fridays)
Crews completed trenching work near the Forest Meadows entrance on Friday Sept. 6. On Monday and Tuesday (Sept. 9-10), crews will be doing cleanup and putting down wood chips over disturbed areas. On Wednesday Sept. 11, crews will resume trenching and installing new pipeline starting near upper Northwood Drive heading up the hill on the south side of Highway 4 for the rest of the week. This work will require one-way traffic control, but delays are generally expected to be fewer than 15 minutes. Crews are using pull-outs along Highway 4 as staging areas, where they are storing heavy equipment, sections of pipe and wood chips that will be used as the project moves forward. Crews will be performing clean-up on sections of pipeline that have already been installed downhill from Forest Meadows.

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.
