Columbia County authorizes pursuit of USDA funding for larger Ellisville wastewater plant, refers options to utility authority

Summary
Facing new nitrogen regulations and capacity limits, the county voted to refer engineering options to the utility authority and to pursue a USDA application for a planned 250,000‑gallon‑per‑day wastewater plant for Ellisville; staff also discussed band‑aid fixes and costs ranging roughly $7M–$10M for different technologies.
County staff told commissioners that the Ellisville wastewater plant cannot currently meet updated nitrogen removal rules and that seasonal and growth demands require more capacity. Staff presented three engineering options to expand capacity (estimates in the meeting materials ranged from roughly $7 million to $10 million depending on technology) and described a temporary fix using FDOT rest‑area sewer capacity to meet a near‑term 100,000‑gallon need.
Commissioners heard a staff recommendation to refer the options to the utility authority for review and to pursue USDA funding for a larger, longer‑term solution — a proposed 250,000‑gallon‑per‑day plant — because building that scale without federal assistance would be infeasible. Staff noted the potential economic-development upside in Ellisville if capacity increases, citing multi‑million‑dollar private investments that could follow expanded infrastructure.
The board voted to refer the technical options to the utility authority for recommendation and approved a motion directing staff to pursue the USDA application; commissioners will review any grant terms or loan conditions returned to the board.
Why it matters: wastewater capacity determines whether the county can support major economic development in the Ellisville area and whether it can meet regulatory nutrient reductions. The decision to pursue federal funding sets the county on a path toward a larger capital project with significant cost and operational implications.
What’s next: utility authority to evaluate engineering alternatives and return a recommendation; staff to submit the USDA application and return to the board with proposed funding terms or loan/grant breakdowns when available.
