Pinellas County commissioners voted unanimously Tuesday to seek $15 million in state grant funding to upgrade a wastewater plant whose pumps have been running for three decades — well past their service life — as flooding risk from sea-level rise and storm surge threatens the aging facility.

The South Cross Bayou Advanced Water Reclamation Facility, a 33-million-gallon-per-day plant serving South Pinellas County near Joe’s Creek in St. Petersburg, provides reclaimed water for irrigation, biosolids for fertilizer, and gas for renewable energy. Its pumps have already reached the end of their expected lifespan, raising the question of why upgrades weren’t planned and budgeted for well before flooding risk turned routine maintenance into an urgent, costly fix.

Commissioners are applying for — and have committed to matching — $15 million from the state’s Resilient Florida Grant Program, bringing the total available funding to $30 million. Even that combined sum falls short of the plant’s projected $41.82 million overhaul cost, leaving county taxpayers or ratepayers likely on the hook for the remaining gap regardless of whether the state grant comes through.

The proposed upgrades include replacing or adding pumping equipment, installing floodproof doors, and relocating windows and electrical wiring — the kind of resilience work increasingly common at aging Florida infrastructure sites now facing decades of deferred investment colliding with rising water levels.

Board of County Commissioners Chairman Dave Eggers formally committed the county to matching the grant funds in a letter to the Florida Department of Environmental Protection, which administers the Resilient Florida Program. “Pinellas County recognizes the importance of investing in resilience initiatives that reduce vulnerability to flooding, sea level rise, storm surge, extreme precipitation, and other climate-related impacts affecting critical infrastructure and community assets,” Eggers wrote, adding that the project would support public safety and protect existing infrastructure investments.

The matching funds, if approved, would flow through the South Cross Bayou high-service pump station improvements project, included in the county’s proposed FY27–FY32 Capital Improvement Plan and funded by the Sewer Renewal and Replacement Fund — meaning ratepayers, not just state grant dollars, will help shoulder the plant’s long-overdue modernization.
