Responsibilities for TSG

Mrs. Fitzgerald, Vice President of TSG, is a civil/sanitary engineer, and participates as project manager and process engineer in the planning and design of TSG's wastewater treatment plant (WWTP) projects. She is a wastewater process engineer and senior project manager with experience in the planning, design, and evaluation of water and wastewater treatment facilities (WWTF) and solids management processes since 1984. Her recent project management efforts have included WWTP upgrades involving alternative project delivery techniques for private resorts and developments as well as upgrades of municipal plants to allow both expansion of capacity and an improvement in effluent quality sufficient for public access reuse. Her expertise in wastewater treatment processes includes biological nutrient removal, membrane bioreactors, sequencing batch reactors (SBR), alternative disinfection methods and sludge thickening and dewatering. Mrs. Fitzgerald works in the company's engineering and fabrication facility in Gainesville, Florida.

Experience:

Mrs. Fitzgerald leads TSG's wastewater projects and is currently working with several private and municipal clients to provide new or upgraded wastewater reclamation facilities. These resort projects require high-tech solutions in small-scale facilities. Two recently completed design/build projects were the Ritz-Carlton and Westin St. John Zenon® membrane bioreactor systems (MBR). TSG is currently operating both of these facilities. Mrs. Fitzgerald is also completing the process design for a 0.54-million-gallon-per-day (mgd), SBR WWTF for the City of Chattahoochee, Florida.

While at CH2M HILL, Mrs. Fitzgerald led the firm's Florida Design Build Group, was the Project Delivery Manager for Florida operations, the Florida Wastewater Technology Coordinator, the Gainesville Water and Wastewater Department Manager and a Senior Project Manager.

Mrs. Fitzgerald was the project manager of the Gasparilla Island WWTP design/build project. This project included a fast-track installation of a 0.5 mgd package plant at an existing golf course in Boca Grande, Florida. The project was completed using the design/build approach to facilitate the 6-month construction window available during the golf course’s off-season. During this 6-month window, an existing circular package plant was removed and replaced by a larger, deeper package plant and an existing concrete package plant was rehabilitated. Construction activities were complicated by the requirement to continue processing wastewater at the existing facility, the tidally impacted surficial groundwater, and an extremely tight construction site.

Mrs. Fitzgerald managed a WWTP expansion in Jacksonville, Florida, that involved replacement of a 3-mgd package plant with SBRs, ultraviolet disinfection, influent and effluent pump stations, biofilters and a centrifuge dewatering system. This design/build project is on an extremely constrained urban site and had an accelerated construction schedule and required phased installation to keep the existing plant in operation. Through equipment pre-purchasing and innovative construction sequencing, the plant was permitted within 11 months of the start of construction, was completed under budget and plant service was not interrupted.

In addition to this plant, Mrs. Fitzgerald provided process evaluations of seven WWTPs in the Jacksonville area for the same private utility. These package WWTPs ranged in size from 0.17 mgd to 3 mgd. These evaluations culminated in expansion designs for three of the facilities and a recommendation to decommission a fourth.
Mrs. Fitzgerald managed the design of the Forsyth County Water Treatment Plant, near Atlanta, Georgia. This project was delivered on an accelerated construction schedule and was constructed in a design/build/operate delivery mode. This water treatment facility is a 10-mgd plant with a construction timeframe of 14 months. It includes SuperPulsators™, filters and ozone.

Mrs. Fitzgerald managed the preliminary design and permitting for an expansion to the Arlington East WWTF for the City of Jacksonville DPU (since acquired by JEA, formerly Jacksonville Electric Authority). This expansion will increase the plant capacity to 15 mgd and includes modifications to the existing preliminary treatment system, the biological treatment system, and the addition of filtration, chlorination, effluent pumping, and storage for a new reclaimed water system. The design and construction of a high-level disinfection system for the plant was recently completed. She also led an effort to evaluate five JEA facilities to determine the cost to convert these plants to advanced nutrient removal.

For the Jacksonville Port Authority, Mrs. Fitzgerald provided a capacity evaluation and permit renewal for the 0.055 mgd Blount Island WWTF. JEA later acquired this plant.

Mrs. Fitzgerald managed the design of a high-rate nutrient removal plant to expand an existing secondary treatment plant that serves Reedy Creek Improvement District resort community in Central Florida. The project includes expansion of existing facilities and addition of a 15-mgd) advanced biological nutrient removal system, denitrifying filters, and gravity belt thickening of waste-activated sludge. The work was performed concurrent with other efforts to assess effluent disposal alternatives and to expand an existing composting system.
Mrs. Fitzgerald also completed a 9-month assignment as the interim chief sanitary engineer for the Reedy Creek Improvement District. In this position, she managed the planning, permitting, and design activities of the water and wastewater systems for the utility.

Mrs. Fitzgerald served as the assistant chief engineer for the design of the Upper Occoquan Sewage Authority WWTP, a 54-mgd advanced treatment facility serving northern Virginia. This plant was designed with both biological and chemical nutrient removal systems and included both chemical and biological sludge dewatering and composting systems.

Mrs. Fitzgerald was the lead design engineer for expansion of the solids handling system for the 40-mgd Virginia Initiative Plant near Norfolk, Virginia. The design included installation of a combination dry and wet polymer feed system, two dewatering and three thickening centrifuges in an existing five-story incineration complex. She also led the predesign of the solids handling facility for the Oceanside WWTP in San Francisco, California. The Oceanside WWTP will be built below-grade and will be covered by an expansion of the San Francisco Zoo.
Mrs. Fitzgerald has designed sludge-thickening facilities for the Main Street and Kanapaha WWTPs in Gainesville, Florida, and the Morristown, New Jersey, WWTP.

She managed several other designs including a solids handling facility and WWTP upgrade for an 8.5-mgd WWTP in Alexander City, Alabama, a solids handling facility expansion for the C.T. Perry water treatment plant in Montgomery, Alabama, and digester improvements and deep injection well pump station at the Ft. Pierce WWTP, Florida.

Mrs. Fitzgerald was also employed as an engineer with Seacoast Utilities, a privately owned water and wastewater utility in South Florida. There she was involved in all facets of utility engineering, including design and construction of treatment and collection facilities; private developer coordination, plan review, state and local agency permitting, and compliance with the requirements of the Public Service Commission.
