A $3M to $5M Solution to Marco’s Water Quality Problems

And it is not Advanced Wastewater Treatment (AWT). AWT induces visions of a bulldozer scraping the Marco Wastewater Treatment Plant (WWTP) down to the dirt and starting over at a cost of over $200,000,000. Not needed.
On October 7, 2022, the City of Marco Island issued a Request for Information (RFI) related to the best value technology methods to reduce nitrogen and phosphorus in the WWTP reuse water.
One of the responses received was from a firm called Phosphorus Free Water Solutions (PFWS). PFWS had been selected by the Florida Department of Environmental Protection (FDEP) as the water treatment contractor for the Piney Point state of emergency resulting from a gypsum stack containment breach. An environmental catastrophe was avoided.
The technology used is a chemical process step for “finishing” or “polishing” nutrients out of sewage reuse water. For the Marco WWTP, the equipment would be housed in two cargo containers and would easily fit into the existing facility. No change to the existing sewage treatment process required. This would also eliminate 90% of the chlorine used in the process, saving an additional $140,000 per year.
This simple project would fix the environmental problem in the Marco canals now caused by excess phosphorus in the sewage reuse water. The cost to clean 99% of the phosphorus and nitrogen out of the Marco sewage reuse water? Between $3M and $5M. The city spends more on pickleball.
