14 Homes on Water Plant Road to Lose Service Monday for Water Line Repair

Fourteen homes on Water Plant Road and Ryan Road in St. Augustine will be without water for an eight-hour span Monday while St. Johns County repairs a water line, the county announced. The planned outage on October 27 will run from 9 a. m. to 5 p. m., and once service is restored, affected addresses will remain under a precautionary boil water notice for at least two days while lab tests confirm the water is safe to drink.

The St. Johns County Utility Department notified customers by door tags over the weekend. The affected properties lie on a stretch of Water Plant Road east of U. S. 1 in St. Augustine, an area that includes a mix of older residential properties near the county's water treatment infrastructure.

What's happening

The outage will affect properties at 2105, 2108, 2128, 2132, 2136, 2138, 2140, 2144, 2148, 2155, 2160, and 2171 Water Plant Road, plus 2090 and 2130 Ryan Road—a total of 14 customer accounts. The St. Johns County Utility Department cited a water line repair as the primary cause of the shutdown.

Under the precautionary boil water notice that will take effect once service is restored, residents must boil all water used for drinking, cooking, making ice, brushing teeth, or washing dishes. A rolling boil of one minute is sufficient, or bottled water may be used as an alternative.

The boil notice will remain in place until laboratory tests show the water meets safe-drinking standards. St. Johns County said that process typically takes a minimum of two days. Residents can call the county's Boil Water Notice Hotline at (904) 209-2731 for updates, and door tags will be posted again once the notice is rescinded.

Why water service must be shut down for repairs

When a water utility repairs or replaces an aging water main, the line must be fully depressurized and drained, requiring a complete shutdown of service to the customers downstream of the work site. Repairing underground water lines typically involves excavation to expose the damaged section, removal or patching of the compromised pipe, and installation of new fittings or segments.

Once repairs are complete and the system is brought back online, the process of refilling the line can introduce air pockets or disturb sediment. More significantly, any time a pressurized water main is opened to the atmosphere—even in a controlled repair—there is a theoretical risk that contaminants could enter the distribution system.

Florida law and Environmental Protection Agency guidelines require public water systems to issue precautionary boil water notices whenever pressure drops below a certain threshold or the system is opened for maintenance, even if no contamination is detected. The two-day hold period allows the utility to collect samples from multiple points along the repaired line and send them to a certified lab for bacterial testing, ensuring no coliform or other pathogens are present.

What residents can expect during the outage

For the 14 households affected, the eight-hour outage means no running water for most of the workday Monday. Residents should plan ahead by filling containers with water Sunday evening or early Monday morning for essential uses such as toilet flushing, hand washing, and pet care.

Laundry, dishwashers, and showers will be unavailable during the outage window. Homeowners may also want to turn off automatic ice makers in refrigerators to prevent the appliance from trying to draw water while the line is dry, which can sometimes strain the inlet valve.

Once service is restored Monday evening, taps may initially run discolored or cloudy due to air in the lines or loosened sediment. Utilities typically recommend running cold-water faucets for several minutes to flush the system before use. However, because the boil notice will be in effect, any water used for consumption must still be boiled or replaced with bottled water during the clearance period.

The two-day testing window means residents should expect the boil notice to remain in place through at least Wednesday, October 29. The county will post door tags when the all-clear is given, and the hotline will be updated as soon as lab results are verified.

A small outage in a fast-growing system

Water Plant Road sits in the older core of St. Augustine, an area where the county's water distribution network includes pipes installed decades ago. As St. Johns County has grown into one of Florida's fastest-growing counties—adding thousands of new homes in master-planned communities such as Nocatee and along the County Road 210 corridor—the Utility Department has balanced expansion with the maintenance of legacy infrastructure.

Planned outages for line repairs are a routine part of that maintenance, though they remain disruptive to the small number of customers affected. Proactive repairs help prevent more serious unplanned breaks, which can flood streets, damage property, and require emergency shutdowns on shorter notice.

While fourteen customers is a small fraction of the county's utility service area, the incident underscores the ongoing challenge of keeping an aging water system reliable even as development pressure and population growth place new demands on the network. For the households on Water Plant and Ryan roads, Monday's outage is a brief inconvenience; for the broader county, it is a reminder that infrastructure built to serve yesterday's population requires constant attention to meet the needs of today's.

Residents with questions about the outage or boil water notice should call the St. Johns County Utility Department's hotline at (904) 209-2731.
