WORK AUTHORIZATION #1 <br /> ENGINEERING SERVICES PROPOSAL <br /> for <br /> NORTH COUNTY ELEVATED WATER STORAGE TANK EVALUATION <br /> Julie 28, 2004 <br /> BACKGROUND <br /> Indian River County Utilities (the County) owns and operates a water transmission system that <br /> provides service to North Indian River County. The County had developed an overall Master <br /> Plan for expansion of its utilities in 1993 with subsequent updates since that time. An elevated <br /> water tank was installed and placed in service during September 1994 . This tank provides storage <br /> and is intended to maintain consistent north water system pressure. Since installation, the growth <br /> of the North County utility and system demands suggests the Tank performance can be enhanced. <br /> The County has requested the assistance of WCG/Neel-Schaffer, Inc . (the Engineer) under the <br /> County' s Continuing Consultant Agreements, to evaluate the North County elevated tank <br /> including propose options to insure storage, pressure and flow are optimized. The Engineer will <br /> prepare a report presenting the results of the evaluation for the County to consider. <br /> The following scope of work describes the services to be provided by the Engineer. <br /> SCOPE OF SERVICES <br /> 1 . Collect and Review Existing Data and Information <br /> The Engineer will collect and review all available information and data related to the County' s <br /> existing north transmission system computer model and tank operation. Information and data <br /> may include previous water system master plan reports, previous studies, water system atlases, <br /> pressure records, record drawings, nearby properties and future land use maps . <br /> The Engineer will also conduct an on-site survey to determine tank and piping elevations to <br /> compare to record drawings of the facility and pressure reading taps. <br /> 2 . Kick Off Meeting <br /> The Engineer will meet with appropriate County staff to discuss tank operation and review how <br /> the overall north County system functions . The Engineer will also inspect the tank as well as <br /> water supply facilities providing potable water to the system . <br /> 3 . Alternative Evaluation <br /> A. Summary of Tank Operation <br /> The Engineer will review the existing data, system pressures, and survey information to compare <br /> the tank hydraulics versus prior north system modeling efforts .
