The study area, referred to as the Sunland/ Industrial Park Sewer System," was constructed during three periods of time. The initial construction provided service to Graham Air Force Base ( currently Sunland Training Center), the second phase was constructed as part of the Industrial Park expansion, and the third phase was a pump station/force main system constructed to eliminate the Sunland WWTP by diverting the flow to the Marianna WWTP.

The pump station receives flows from five (5) force mains with a total combined flow of 2, 083 gallons per minute (gpm) and a small gravity flow from the Panama City -Bay County International Airport. Scope of work included force main network modeling involving multiple pump stations pumping into a common force main, available alternatives, future conditions impact, and recommendation on future course of action.

Since the 1960s, the City of Marianna has provided wastewater collection and treatment services to the commercial and residential population within and around the City. The existing Marianna Wastewater Treatment Facility is permitted to treat 2. 7 million gallons per day ( MGD) of wastewater. In 1997 and 1998, the facility received flow exceeding the design and hydraulic capacities. These high flows, coupled with other features of the facility, have created operational difficulties that ultimately led to the execution of a Consent Order. Among other stipulations, the Consent Order requires the monthly average daily flow (MADF) from the facility to be 2. 7 MGD until the proposed WWTF expansion ( currently in construction phase) is complete. In March 2003, after several years of drought conditions, the City experienced several heavy rain events, which caused the MADF to exceed the permitted 2. 7 MGD; this had the potential of triggering a moratorium on any new commercial sewer connections. The City took a pro- active approach and retained services of Hatch Mott MacDonald to assist the City in conducting a preliminary excessive I/I analysis.

The increased flows can overload the sewer collection and treatment systems, increase operational cost, and increase the potential for a sewer overflow, which poses a threat to public health and safety and to the environment. Contact Information City of Panama City Mr. Ron Morgan Director of Utilities 850. 872. 3000 SummerCamp /St. James Island Franklin Countl%14orida Hatch Mott MacDonald completed a water and sewer master plan for the 499 -unit development known as SummerCamp. After the water master plan was completed, Hatch Mott MacDonald designed the water supply, treatment, storage, pumping and distribution systems. This included two 125 GPM wells, the first nano -filtration (membrane) water treatment plant permitted by the Northwest District of FDEP, a 150,000 gallon ground storage tank and a high service pump station. The system is designed to add another well, another membrane train and a second ground storage tank. Contact Information St. Joe Company Sean Fennelly 850) 402 -5126 Expansion to T.P. Smith Wastewater Treatment Facility Tallahassee, Florida The staff of Hatch Mott MacDonald., designed the expansion to the T.P. Smith Wastewater TreatmentFacility in 1977. The 1977 design constructed in 1982) expanded the facility from 10. 0 MGD to 17. 5 MGD. Features in 1977 included primary clarifiers, sludge thickening and sludge de- watering.

I- orida % This project involved the development a 20 -year master sewer plan for the Southwest area of Escambia County. Included with the project were recommendations for improvements, phasing requirements and growth projects for the area. The Escambia County Utilities Authority (ECUA) manages water and wastewater systems for the residents of Escambia County and the City of Pensacola. The ECUA system area is subdivided into 5 Regional Service Areas for response time and management optimization. The Southwest portion of the County is designated as ECUA' s Region 5, and includes ECUA' s systems west of Fairfield Drive and south of the Bayou Marcus Water Reclamation Facility, located just north of the intersection of Blue Angel Parkway and Lillian Highway. The objective of this study is to identify wastewater force main system deficiencies within ECUA' s Region 5 and provide recommendations for system improvements for the present, near future and ultimate wastewater flow projections. Obtaining existing ECUA system mapping, lift station and force main inventory and operational parameters was the initial step in the study. ECUA' s most current system mapping, as -built information and field monitoring data were compiled for ECUA' s existing force main system in Region 5. System as -built information and USGS quadrangle information were used to develop system topographical parameters. Population projections and associated wastewater flow for future system demands were estimated and broken down into FDOT PUATS Traffic Analysis Zones to best identify future growth within the study area. Escambia County Drainage Basin Maps were used in conjunction with ECUA' s current system mapping to best approximate future wastewater flow distribution within Region 5.
