WaterWorks 2011 City of Fort Lauderdale Capital Improvements Program

Overview

The WaterWorks 2011 Program entails the modernization of the City of Fort Lauderdale water and wastewater infrastructure to be completed over a period of 10 to 20 years. The majority of the improvements will be completed by 2011 using a Program Management approach and a dedicated Program Management Team (PMT). The program management processes, tools, and skills developed during execution of the Program are anticipated to set the stage for the City to continue with the implementation of additional capital improvements that may be needed beyond the first 10 years of the Program.

Included below is a brief description of the improvements currently planned as part of the Program on the basis of the City of Fort Lauderdale Water and Wastewater Master Plan (CH2M HILL and Hazen and Sawyer, February 2001). Approximately $320 million are planned for improvements to the water system and $230 million for improvements to the wastewater system.

The initial year of Program Management activities will focus on detailed planning activities that will further define the elements and delivery strategy for the individual projects within the Program.

Water System Improvements

Near term improvements to the water system include miscellaneous wellfield upgrades, a new membrane softening treatment facility at the Peele-Dixie WTP, multiple rehabilitation/upgrade projects at the Fiveash WTP, and new pipelines and storage tanks in the distribution system. Long-term improvements include wellfield upgrades and membrane filtration technology upgrades at the Fiveash WTP, and distribution system piping improvements.

Wastewater System Improvements

Improvements to the wastewater system include the addition of previously unsewered areas into the collection system, modification of the existing collection system, repair and upgrade of the transmission system, and improvements at the wastewater treatment plant.

The proposed transmission system improvements consist primarily of pump replacements to upgrade equipment and alleviate hydraulic deficiencies. A major new force main along Davie Boulevard is proposed in the near-term to provide the conveyance capacity that will be needed for connection of new sewered areas, and to provide an alternate flow path into the treatment plant. Longer term, three additional force main segments are proposed. These are needed to relieve localized capacity problems and/or to provide additional capacity for connection of presently unsewered areas.

Proposed collection system improvements include rehabilitation of existing sewers and construction of new sewers in presently unsewered areas. The coordinated system-wide program of sewer system rehabilitation was initiated in late 2000 and will be ongoing throughout the 20-year planning period. Initial efforts will focus on the identification and reduction of peak flows associated with rainfall-related infiltration/inflow. Expenditures for contracted sewer rehabilitation of $3.5 million per year are recommended to achieve the objectives of the program.

Eighteen unsewered areas have been delineated in the service area. Construction of new sewers in each of these areas is proposed, with the construction being phased over the next decade.

With the anticipated re-rating of George T. Lohmeyer RWWTP to a capacity of 54 mgd, the plant will have sufficient capacity for many years. No expansion of treatment or effluent disposal capacity is recommended, but a number of renewal and replacement projects are proposed.

Capital Improvements Summary

The projects included in the approved Master Plan are categorized as near-term (through FY 2005) and long-term (through FY 2020), and are further categorized by type of system (water, wastewater) and by function (supply, treatment, distribution, collection, transmission, and disposal). A summary of projected investments in each category through the year 2020 are shown below.
