Proposa/ Comprehensive Water Distribution System Audit area which has a moratorium imposed by the State Engineer); and to provide mast cost effedive infrastrudure for the transportation distribution and storage of this water to lands that do not have water. EastCanyonWoterlineis port of ihese services. Providing engineering services for design and constructian management of 72,000 feet of 30-inch diameter ductile iron high pressure (in excess of 465 psi) waterline. A Booster Station and Intake Strudure were alsa part of the projed. Providing engineering services for design and construdion management for 6.5 mgd pump station and intake strudure, ezpandable to 22 mgd, to pump water more than 1,100 feet vertically6om East Canyon Reservoir ta Snyderville Basin. Microfiltration WaterTreatment Plant. Praviding engineering services for design and construction of 22 millian gallons per day water treatment plant. The first phase being 6.5 million gallons perday. Dallas Water Utilities Eastern System Drought Implementation Plan Dallas, Texas The projed included the ezpansion of the ezisting 230 MGD raw water pump station to a firm capaciry af 310 MGD, and the design and construdion of the 241 MGD Lake fork Pump Station and 108-inch rawwotertransmission main. The drought conditions implementation plan developed population forecasts and per capita demands to determine total system demands through 2050. These demands were compared with demands developed by regression- extrapolation onalysis in order to determine the final demands used for planning. Costestimateswereprepored to connect Lake Fork into the DWU system including the Lake Fork pump station and transmission line. Additionally, six long range water supply alternatives were evaluated for ronneding Lake Palestine, George Parkhouse Carter :.Burgess No. 2, and Marvin C. Nichols No.1 to the Dallas system. Planning level construdion cost estimates and 0&M cost estimates were developed for each of the six alternatives. The total system corn were in the range of 5750 million, and induded new pump stations, a new surface water treatment plant, and over 100 miles of lorge-diameter iransmission lines. Total improvements for the pump station are estimated to be S14 million in three constructian contracts. Four new 68 MGD pumping units and 4,500 NP matars will be installed, olang with discharge and header piping. The instrumentation and controls at the faciliry are being upgraded bemuse the faciliry will be remately operoted from the East Side Water Treatment Plant after the installation of a new SCADA system. Iron Bridge Pump Station Renovation ~r Upgrades Dallas, Texas The Iron Bridge Pump Statian, ariginally construded in 1964 on Tawakoni Lake, has an existing capocity of approximately 220 MGD. It is a significant component in the Ciry of Dallas' raw water supply system, possessing nearly one third of the City's raw water pumping capaciry. (arter 8 Burgess is providing renovations ond upgrodes to increase pumping mpociry to 310 MGD, improve system reliability, extend the life of the faci liry for another 30 years and provide the capabi lity of a totally remotely operated stati on through the use of a S(ADA system. The initial phase of the projed involved preparation of a desiqn report that included condition assessments and upgrade recommendations for all structural, civil, mechanical, eledrical and architedural romponents of the pump station. Key recommendations included re- configuration of four ezisting 40-MGD pumping units, installation offour new 65-MGD pumping unih, replacing piping and valves, intake screens, sluice gates and all eledrical, instrumentation and controls. This phase also included providing internal inspedions and surge analysis 10
