JEA
Nassau County Regional Wastewater Treatment Facility

JEA (Jacksonville, Florida) provides electric, water and sewer services to more than one million people on Florida's First Coast. It is the largest municipal electric utility in Florida, and it operates the second largest water and sewer system in Florida.

When JEA was planning upgrades to three of their wastewater treatment plants they contract TSG to help identify the best treatment technology for expanding each plant.

JEA was considering using membrane bioreactors (MBRs) for these plants but had no experience with this technology. They called on TSG to evaluate the feasibility of MBRs and to compare it with conventional wastewater treatment systems. As a result of this study, JEA elected to expand the Nassau County Regional WWTF with MBRs. They contracted TSG to prepare a preliminary design for submittal to FDEP for permitting and to assist JEA in the preparation of design/build specifications for this 2 mgd nutrient removal facility. Three membrane systems were pre-qualified for bidding, Zenon ZeeWeed, USFilter Memcor, and Enviroquip Kubota. The selected design-build team is using the Kubota system.

TSG has worked closely with both FDEP and JEA to help oversee permitting and implementation of this state of the art technology. This project is the first MBR system to be permitted by the Northeastern District of the Florida Department of Environmental Protection (FDEP) and one of the first MBR systems permitted to provide advanced nutrient removal as well as public access reuse.
