We Have One of the Purest Water Supplies in the Nation

The Murphree Water Treatment Plant treats and supplies water to all of Gainesville. We're fortunate in Gainesville to be able to tap into the Floridan Aquifer for our water supply. It is some of the purest water found anywhere in the country — the quality of water from our Murphree Water Treatment Facility meets all state and federal standards.

The Murphree Water Plant was recognized  by the American Water Works Association as the "Best Water Treatment Plant in Florida" in 2017 and has been named numerous times as the "Best Operated Plant" by the Florida Department of Environmental Regulation.

Water Quality

GRU takes great care to ensure that our water remains safe and available on demand for approximately 200,000 residents. Gainesville's water consumption is about 23 million gallons a day on average, but to handle the extra demand placed on the system by drought conditions, we have constructed additional supply wells (for a total of 15 wells) — allowing us to pump and deliver up to 54 million gallons of high-quality drinking water per day. Our consumptive use permit allows us to provide our customers with up to 30 million gallons per day of high-quality drinking water. GRU delivers approximately 8 billion gallons of drinking water to our community every year.

  • Minimal treatment of the water drawn from the Floridan Aquifer is required. Nevertheless, it is closely monitored throughout the multi-step treatment and distribution processes.
  • Personnel from our Murphree Water Treatment Plant test the drinking water on an hourly basis and conduct additional testing throughout the distribution system. Over 63,900 samples are analyzed each year. 
  • Although a virtually impermeable layer of clay protects the aquifer in this area, GRU purchased and maintains a conservation easement for 7100 acres surrounding our water plant. This in order to protect the aquifer against possible contamination.
