The pilot facility will support research to investigate direct potable reuse as a future water supply option. The Cherry Hill pilot DPR treatment process begins with the transfer of treated effluent from the Northwest Regional Wastewater Treatment Plant. The water is then further treated through a series of processes, using a multi-barrier treatment approach. The process includes various technologies, including flocculation/sedimentation, ozone, biological granular activated carbon, ultrafiltration, and ultraviolet disinfection, and cleans recycled water, addressing chemicals, pharmaceutical residue, hormones, bacteria, protozoa, and viruses.

While the potable reuse treatment method has been previously used by several pilot projects in other parts of the country, Polk County is the first in Florida to conduct the feasibility at a water treatment plant rather than a wastewater plant. The Cherry Hill pilot facility will generate data for 12 months to demonstrate the feasibility of its process. After that time, the county will continue to operate the facility to educate visitors about DPR’s viability as a safe, reliable drinking water source.

“The development of alternative water supply will help offset over-pumping of groundwater, augment the water supply, and reduce environmental impacts,” says Dewberry Senior Associate and Senior Project Manager Matt O’Connor, PE. “We are excited to be a part of this important step in securing the water supply for the people of Polk County.”
