They’ve arrived, they’ve been installed, and they’re adding a new level of treatment to Cedar Key’s drinking water: four large granulated activated carbon (GAC) filtration vessels.

GAC Filtration Equipment


After the District’s drinking water goes through its usual multi-stage treatment process, these filtration vessels will provide a final polishing of the water before it is sent out to customers.  The primary motivation for installing these filters is the need to reduce disinfectant byproducts (DBPs) in the water. The District has shared the problem of reducing these byproducts with many other utilities, and has tested many possible solutions over the years. The installation of an ion exchange treatment process back in 2006 brought the DBP levels down below the maximums for most of the time, but there have been occasions when the levels have exceeded the maximums, probably due to the variability of the water the District draws from its well field.  Such exceedances are not an immediate health risk, but the State requires utilities to move towards reducing the levels over the long term. 


After successful testing of GAC filtration, the District is confident that the new filtration will keep the DBP levels consistently below maximum state-imposed levels. The District will be conducting monthly testing of the DBP levels and updates will be provided to customers.

The directional drilling project to remove aging wastewater lines from Bridges 1, 2 and 3, and place them underground beneath the waterways has been successfully completed. A generous “RIVER Grant” from the Suwannee River Water Management District aided the Cedar Key Water and Sewer District in getting this work done by funding half of the $180,000 project. The work was ably performed by General Underground LLC out of Chiefland. 


The Water and Sewer District’s wastewater collection and treatment system was installed in 1981, and wastewater collection pipes were attached to the sides of Bridges 1, 2, and 3 on State Road 24, as well as on other bridges in Cedar Key. These aging PVC pipes were exposed to the elements, and there were various threats to their integrity, including collision by boats, damage by storms, and brittleness due to age. A substantial spill of wastewater into Cedar Key’s Class II shellfish waters could have a devastating impact on the environment and economy of Cedar Key. With the completion of this project, wastewater lines on all bridges in Cedar Key have been removed and buried underground, and the threat of a wastewater spill into Cedar Key’s waters has been greatly reduced.
