Proposa/ <br />Comprehensive Water Distribution System Auclit <br />Section 3 <br />Relevant Project Experience <br />The Carter & Burgess staff have been responsible for the <br />planning, design, and management of a wide variety of <br />projects. These projeds have been performed ocross not <br />onlyTexas,butaraundthenation. Representativeprojeds <br />are provided below. <br />Weatherford Water <br />Purification Plant <br />Treated Water Flow <br />Metering Evaluation <br />Weatherford, Texas <br />The City ofWeatherford water departmentemployees noticed <br />the City had an unacceptablyhigh percentage of unacrounted <br />far treoted water. The Ciry hired Larter & Burgess, Inc. ta <br />investigate the possi6le causes far this unaccounted for water. <br />The City had more than 15 percent of its water supply <br />unaccounted far. Normal lass is around 10 perceM, while a <br />5 percent loss is considered good. The ciry's water plant <br />produces 8 million gallons of water per day. (arter 8 <br />Burgess engineers decided the woter may not be leaving the <br />system, but that it was not accounted for in the process. <br />Engineers calibrated the water meters and looked at the <br />accounting system. <br />Hurst Water <br />Distribution System <br />Master Plan <br />Hurst, Texas <br />Carier & Burgess, Inc. prepared a Water Distribution System <br />Master Plan forthe Gtyof Huatwhich included computerized <br />modeling of the firy's water system, a written report, <br />software acquisition and training for Hurst Public Works <br />staff. Theprojectwasperformedtoevoluateewstingsystems <br />and plan for future expansion and growth of the distri bution <br />system. The Liry of Hurst is more thon 90 percent built-out <br />and dces not anticipate ezpansion of its current boundaries. <br />The projed focused on operational issues such as energy <br />efficienry, redudion of peaking charges for purchosed water <br />and qualiry issues resulting from mixing well water ond <br />surface water. A GIS system was linked to the hydraulic <br />modeling sohware Cybernet, ta assist visualizing patterns <br />and trends in water use and compare the outcome of several <br />design scenarias. Our GIS staH developed digitized data of <br />water lines and complete attributing for all features. <br />The projedwas performed in hvo parts. Part One involved <br />generalized camputer modeling of the Hurst Water <br />Distribution System in order to analyze the system's <br />operational efficienry and determine the most cost-effedive <br />system enhancements. This phase included data colledion <br />from water system maps, topographic maps, land use maps, <br />previous water distribution system master plans, water-use <br />studies, population figures and as-builtconstrudion plans. <br />Next, water usages were analyzed; ond a model was created <br />for evaluating the system. A future system model was <br />developed to reflect projected system changes in <br />configuration, operatians and water demand. Our engineers <br />then seleded various operatianal scenarios for anolysis by <br />computer madeling and then prepared a report which <br />outlinedtheresultsoftheanalysis. Designated Public Works <br />staff were hained on the detoils of the water system modeling <br />an an ongoing basis throughout the development of the <br />study. Training for basic manipulation of the data in the <br />system was also provided. <br />Part Twa of the projed required Carter 8 Burgess to oddress <br />the (iry's abiliry to meet current and proposed state ond <br />federal water qualiry regulations, and conduct a park <br />irrigationstudy. Regulatory issues evaluated included Lead <br />and Copper Rule, Surface WaterTreatmenf Rule, Information <br />Colledion Rule, Disinfedion and Disinfection By-product <br />Rule, and Enhanced Surface Water Treatment Rule. Forthe <br />park irrigation study, alternative sources of irrigation were <br />investigated for three [iry of Hurst parks. Engineers <br />investigated treated wastewater effluent and local water <br />well supplies as potential sources of i rrigation, reviewed the <br />potential availabiliry ofsuch sources, and prepared a report <br />Carter ::Burgess <br />6 <br />
