JACKSONVILLE, Fla. – Water restrictions are tightening across parts of Northeast Florida as officials move the region into Phase III drought conditions, prompting questions from residents about what is driving the change and how it affects daily water use.
After News4JAX reported on Phase III drought conditions in Northeast Florida, viewers raised questions about what is driving the restrictions, including concerns about development and data centers, and how the changes will affect local water use.
Following those questions, News4JAX reporter Briana Brownlee spoke with water managers to get answers on what is behind the restrictions and what they mean for the region.
The St. Johns River Water Management District says the move comes after months of significantly below-average rainfall and declining groundwater levels across Northeast Florida.
Officials say the region is about 20 inches below normal rainfall over the past year, a deficit they say is contributing to lower aquifer levels and reduced water availability.
Why are water restrictions happening now?
Water managers say Phase III restrictions are based strictly on environmental conditions such as rainfall totals, groundwater levels and drought indicators — not sudden spikes in water use or population growth.
“Our Phase III is strictly based on rainfall and groundwater levels… we are about 20 to 25 inches below normal for rainfall, and that translates into our aquifer levels being extremely low, and that’s what triggers the water shortage,” said Carlos Heard, regional water supply coordinator with the St. Johns River Water Management District.
Despite ongoing development in parts of the region, Heard said overall water use in North Florida has remained relatively flat over the past decade, a trend they attribute to conservation efforts and more efficient water use.
Are development and data centers driving water demand?
One of the most common viewer questions has been whether development or large facilities, such as data centers, are contributing to water shortages.
“Data centers are incorporated into our water use data. So if we aren’t showing an increase in water use from our utilities, then they aren’t really having much of an impact on our system or our water use,” Heard said.
He added that current monitoring has not shown any significant increase in overall water demand tied to those uses.
What uses the most water?
Officials say residential irrigation remains the largest share of water use across North Florida.
“If you are looking at water use, our largest water use is residential irrigation, and what some of your viewers might not know is that an average irrigation cycle uses a thousand gallons of water. So if you add that up, for a thousand times every house we have in north Florida, that’s a lot of water,” Heard said.
During dry conditions, outdoor watering becomes one of the most significant drivers of demand on potable water systems, according to water managers.
What do the new restrictions mean for residents?
Under Phase III rules, outdoor watering continues to be limited to one day per week for residential, commercial and institutional users. Additional restrictions apply to larger water users and non-essential uses.
Watering is also prohibited between 8 a.m. and 6 p.m., and stricter limits apply to new landscaping and irrigation systems.
What is being done to help customers conserve?
JEA says customers can sign up for usage alerts that notify them if their water use spikes unusually.
Officials say the alerts are part of broader conservation efforts that also include irrigation assessments, leak detection programs and education campaigns aimed at reducing unnecessary water use.
Will conditions improve soon?
Water managers say the drought is driven by weather patterns, and future relief depends largely on rainfall.
Officials are urging residents to conserve water as dry conditions are expected to continue in the near term.
