A partnership between Florida Power & Light (FPL) and Miami-Dade County has brought “one of the largest” reclaimed water projects in the state online, which will treat up to 15 million gallons of reclaimed wastewater per day to cool the natural gas plant at FPL’s Turkey Point Clean Energy Center.
The clean water recovery process begins when reclaimed water travels through an 8.5-mile pipeline into the Biological Nutrient Removal (BNR) basin at the new Clean Water Recovery Center (CWRC). Different treatment zones within the BNR basin remove ammonia and condition solids, which are then clarified. During clarification, phosphorus is removed before the water is chlorinated and stored in two 500,000-gallon tanks. The treated water is ultimately used to supply cooling towers, reducing the need for Floridan aquifer groundwater.
In addition to cooling the gas plant, the project is meant to help Miami-Dade County meet reuse requirements under Florida’s Ocean Outfall Legislation, and provide a cost-effective way to reuse treated wastewater which would have likely been discarded otherwise. The Ocean Outfall Legislation requires utilities in Southeast Florida to eliminate the normal use of the ocean outfall, or stop feeding treated wastewater into the ocean, by the end of 2025. Additionally, Florida has its own standards for the amount of treated wastewater that local governments must reuse, the Miami Herald reports.
The CWRC project was originally intended to help cool FPL’s two nuclear reactors at the Turkey Point site, but those plans changed before the project’s launch, per the Miami Herald.
“There was, in the planning stages, an idea of having it assist, as needed, a backup to the Turkey Point nuclear cooling canals,” an FPL spokesperson told the Miami Herald. “The decision was made not to do that.”
FPL and Miami-Dade County have partnered on clean energy projects since 2018, including the Miami-Dade Solar Energy Center, dozens of solar arrays, battery storage projects, shore power for PortMiami, a microgrid at Florida International University (FIU) and a growing electric vehicle charging network.
Last September, the U.S. Nuclear Regulatory Commission (NRC) approved the subsequent license renewal for FPL’s Turkey Point Nuclear Power Plant Units 3 and 4, enabling the continued operation of these units through 2052 and 2053, respectively.
Turkey Point Unit 3 began commercial operation in 1972, followed by Unit 4 in 1973. Located 25 miles south of Miami, the site sits on 11,000 acres of land. In December 2019, Turkey Point became the first nuclear plant in the United States to receive subsequent license renewal approval for an additional 20 years; however, in 2022, the NRC concluded that its general environmental review under the National Environmental Policy Act required additional information and, consequently, resetting the previous operating license expiration dates of 2032 and 2033.
