City Breaks Ground on Second Phase of Wastewater System Improvements with State and District Partners

March 23, 2021 – The City of Green Cove Springs, with officials from St. Johns River Water Management District, Florida Department of Environmental Protection, Mittauer & Associates, and Williams Industrial Services, LLC, broke ground Tuesday morning on its new 1.25 million gallon per day advanced nutrient removal wastewater treatment facility at its Harbor Road Wastewater Treatment Plant.

This is the second phase of the City’s three-phase wastewater system improvements, which are a combination of new construction and upgrades to the existing wastewater system. The new facility will further reduce nitrogen and phosphorous discharges into the St. Johns River. The improvements will also allow the City to filter more wastewater into reclaimed water, reducing the amount of potable water used for irrigation.

 “The new facility will reduce nutrient discharge into the St. Johns River, increase the utilization of reclaimed water and reduce the withdrawal of potable water from the Floridan Aquifer (City’s wells),” said City of Green Cove Springs Assistant Water Utility Director Scott Schultz.

The City contracted Mittauer & Associates for planning and design of the three-phase wastewater system improvements, and Williams Industrial Services, LLC, to construct the Phase Two advanced wastewater treatment facility. Construction is expected to last 20 months, with an estimated completion date of November 2022.

The facility is partially funded by a $12 million Florida Department of Environmental Protection, State Revolving Fund Loan—which includes a $4.5 million grant. It is also partially funded by a $1.5 million grant from the St. Johns River Water Management District Cost Share Program. The total cost of this phase of facility improvement is $15,426,644.33.

“Partnerships with local governments are crucial to implementing innovative solutions. Not only will this project help reduce nutrients in the St. Johns River but it will also help support potable water resources,” said Florida Department of Environmental Protection, Northeast District Director, Greg Strong. “We look forward to working with the City and our partners to ensure our resources are protected for generations.”

“We are excited to join with the City of Green Cove Springs and Florida Department of Environmental Protection on this great partnership project, which will ultimately connect the entire city’s wastewater system to the state-of-the-art Harbor Road treatment facility,” said St. Johns River Water Management District Executive Director Dr. Ann Shortelle. “The project will reduce nutrients that can fuel harmful algal blooms and impair water quality in the lower St. Johns River and reduce the use of fresh groundwater for landscape irrigation.”

Phase one of the City’s wastewater system improvements included a 1.25-million-gallon reclaimed water storage tank, reclaimed water pumping and pressurization systems, and upgrading the electrical infrastructure to support Phase Two improvements, and future expansion of the facility to 3.75 million gallons per day. Phase three will decommission the City’s South Wastewater Treatment Plant and transition the treatment of all wastewater in the City service area to the Harbor Road Wastewater Treatment Plant.
