City of Fort Walton Beach – Water Treatment/Reuse
Fabre Engineering & Surveying recently completed design efforts on three major projects for the City: The Golf Course Water Treatment Plant and Elevated Storage Tank (construction cost $2.3 million); The Water Transmission System and System Storage Improvements (construction cost $3.0 million); and The City of Fort Walton Beach Reuse Project (construction cost $1.0 million).
The Golf Course Water Treatment Plant and Elevated Storage Tank Project consist of an ozonation and booster pumping facility capable of treating and pumping 4,000 gallons per minute. This project was the result of the “Golf Course Water Treatment Plant Preliminary Engineering Study” authorized by the City to study various forms of treatment to combat a ‘black’ water problem. Various forms of treatment including cascade aeration, forced draft aeration, ozonation, and chlorination were studied to determine the most effective course of treatment. The project also includes a new 1.0 million gallon pedesphereoid type elevated storage tank. The elevated tank and booster station design were based on a computer model of the water system and its operation.
During the course of modeling for the design of the treatment project, it was discovered that there were significant operational restraints on the City’s ability to move water from the north part of the system to the City center at Highway 98. As a result, the City authorized the “Golf Course/Downtown Transmission Line Improvements and Downtown Elevated Storage Tank Improvements Preliminary Engineering Report.” This study analyzed various routes for transmission system upgrades to allow the City to move water produced in the north part of the City to the City center. The study also analyzed the possible alternatives for combining all three distinct pressure zones into a single system and for the best location for a new elevated storage tank to replace three, aged tanks at differing hydraulic grade lines.
The third project involved the design of a reuse line from the Hurlburt Air Force Base wastewater treatment plant to the City of Fort Walton Beach. This project is a joint effort between Hurlburt Air Force Base and the City made possible by a Defense Infrastructure Grant obtained by the City. Fabre Engineering & Surveying provided all engineering study, design, and surveying work for all three projects and was responsible for complete system analysis, computer modeling, report preparation, and preparation of construction plans and contract documents.
