What came of all those weekday closures on Little John Road last winter? According to myMotherLode, work started December 8, 2025, and closures were planned through March 13, 2026. The work moved in seven segments, from Kiva Place to Moccasin Street and on past Flint Trail, South Bow Drive, Saddle Creek and North Bow Drive, then up Charmstone Way from Quail Hill Road to the Calaveras County Water District tank site.
The digging is over. A November 3, 2026 Engineering Committee report from CCWD says Mozingo Construction has installed the new 20-inch water transmission main and finished final paving on Little John Road and the other permitted road segments. The same report says the booster pump station's electrical components should arrive by February 2027 and blames industry-wide delays driven by high demand. So the pipe is in the ground, and it won't carry water until those parts arrive and are installed. It also has to be in service before the next Copperopolis water project, along O'Byrnes Ferry Road, can do its job.
The bottleneck the new pipe is built to remove
CCWD's project page explains today's setup. Every gallon treated at the Copper Cove Water Treatment Plant is first pumped up to the B Tanks. Water bound for the C Zone is then pumped a second time, through an older B-C Zone booster station, to the C Tanks on Charmstone Way.
That second station is too small for the demand it serves:
| Flow measure | Gallons per minute |
|---|---|
| What the existing B-C booster station can deliver | about 1,100 |
| Current peak demand | about 1,600 |
| Expected future demand | about 2,500 |
CCWD says that on hot summer days the system can't keep the C Tanks full, which cuts reliability and limits fire protection when demand is highest.
The fix runs about 12,000 feet of 20-inch ductile iron pipe from the booster pump station at Kiva Place, near the end of Little John Road, up to the C Tanks. Three new high-head pumps will push water through it, and water will then flow downhill by gravity to feed the B Tanks. That replaces the two-step pumping. No homes connect to this line. CCWD calls it a dedicated transmission pipeline for moving treated water to higher elevations, so nobody's tap will change the day it starts running.
The 20-inch size matters too. CCWD's engineering studies found a 16-inch pipe would fail disinfection requirements. The C Tanks have limited internal baffling, so part of the chlorine contact time has to happen inside the pipe on the way uphill. CCWD expects better pressure control, more fire flow, less risk of main breaks and household plumbing damage, and fresher water once the job is done.
The district opened bids in March 2025, got six of them, and awarded Mozingo Construction a contract of about $8.26 million. The capital project as a whole, listed as CIP 11122, carries a $10 million budget in CCWD's October 28, 2026 board package. That package lists $8,009,680 spent so far and the project 80 percent complete.
Why the C Tanks matter to the east shore of Lake Tulloch
This is where the Little John Road pipe starts to matter well beyond Copper Cove.
East of Lake Tulloch, roughly 750 homes and other domestic water customers get their water through one 10-inch distribution main laid across the bottom of the lake. CCWD's environmental filing on the state CEQA database says that if that main fails, the whole east-side community loses its water supply. A March 18, 2026 CCWD board package describes the cross-lake pipe as aging and in a vulnerable spot, and says it can't be easily repaired because it sits under the water.
The planned answer is the Lake Tulloch Intertie, and it begins at the C Tanks. The May 2026 bid specifications call for about 12,700 feet of 12-inch ductile iron transmission main running from the C Tanks to the B4 Zone east of the lake. The specs also include a pressure-reducing valve station near Sanguinetti Drive, plus air vacuum release valves, fire hydrants and gate valves. The route follows O'Byrnes Ferry Road, starting south of Cosmic Court and heading toward Sanguinetti Drive and Conner Estates Drive.
The two projects form a chain:
- The new pumps at Kiva Place push treated water up the Little John Road main to the C Tanks.
- The intertie carries water from the C Tanks along O'Byrnes Ferry Road to the B4 Zone on the east side of the lake.
- The east shore no longer relies on the single main across the lake floor.
The March 18 board package says intertie construction will follow completion of the C Transmission and Booster Pump Station project. It also points to a local side benefit: the new line brings water to stretches of O'Byrnes Ferry Road that have no water service today.
What's on the calendar for O'Byrnes Ferry Road
CCWD's board voted at its August 12, 2026 meeting to award the intertie construction contract to Ford Construction. The November 3 committee report says staff is reviewing the contractor's material submittals and expects construction to begin in early 2027.
For drivers who use O'Byrnes Ferry Road every day, the bid documents describe how the work will run:
- Roads must reopen at the end of each workday, and access to adjacent properties must stay open.
- Lane closures on Sanguinetti Drive require coordination with the private property owner.
- The contract calls for substantial completion within 195 calendar days and final completion within 225 calendar days after the contract clock starts.
Last winter on Little John Road, residents got a segment-by-segment closure list ahead of the work. CCWD's own project page for that job later posted a rolling three-week schedule.
The intake end of the same system
The Copper Cove system also gets its raw water from Lake Tulloch, through pumps in the lake that feed the treatment plant. One of those pumps, Upper Lake Pump 2, failed this year. CCWD replaced it with help from a professional dive team, which decontaminated its boats and equipment before entering the water. The district marked the job complete on June 26, 2026. The Little John Road main and the intertie take over from there, moving that treated water uphill and then across to the east shore.
Copper Cove's wastewater side has work coming too. The November 3 report says CCWD secured another $3.1 million in federal Section 219 funding for the Copper Cove Pond 6 tertiary filtration project, to cover higher construction costs. District crews have already poured a concrete pad for the new filter unit.
The bill changes in January, and the rates don't
The change most Copperopolis households will notice first is on paper. CCWD's billing page says customers will start getting a bill every month beginning in January 2027. It works a little differently than "monthly" suggests:
- Water base rates will be billed monthly.
- Sewer base rates will be billed monthly.
- Water consumption charges stay on a two-month cycle, covering two months of usage.
CCWD says the water and sewer rates themselves aren't changing and that customers don't need to do anything for now. The board talked through the cost of the switch on September 16, 2026. Staff estimated annual billing-related costs of about $711,800 under monthly billing, compared with $430,400 under the current schedule, and a board majority directed staff to keep working toward the January transition while looking for ways to lower those costs. CCWD Customer Service can be reached at (209) 754-3543 or [email protected].
For the water system itself, the next date on CCWD's calendar is February 2027, when the electrical components for the Kiva Place booster pump station are due.
At Baxter Luxury Home Team, we follow projects like this because they affect everyday life in Copper Cove and on the east shore. If you'd like to talk through how the Little John Road main or the O'Byrnes Ferry Road intertie relates to a home you own or are considering, schedule a consultation with Kevin and Terri, and we'll go over the CCWD schedule with you.
