Lake Fork Pipeline Dallas, Texas Carter & Burgess is designing 26 miles of 108-inch raw water transmission line for Dallas Water Utilities. The line has a hydraulic capaciryof 216 M6D and will run from the lake fork Pump Station on the western shore of Lake Fork to the viciniry of the Iron Bridge Pump Station on the west shore of lake Tawakoni. The scope of services includes hydraulic design, alignment selection, right-of-way document preparation and acquisition services, surge analysis and on-site construction representation. Lake Palestine Water Utilization and Pipeline Alignment Project Dallas, Texas Larter & Burgess performed detailed utilization and alignment studies to develop preliminary plans for a 120- MGD rawwater intake and pump station at Lake Palestine, more than 85 miles of 84-inch raw water pipeline and associated appurtenances from lake Palestine to Dallas, and the 300-MGD Southeast Dal los Water Treatment Plant, the pipeline's terminus. The assignment involved preparation of preliminary hydraulic designs, alternate route Carter :.Burgess studies and site seledion for the water treatment plant and the rawwater intake/ pump station; alternate route studies far conveyance facilities; selection of final olignmentforthe raw water pipeline; right-of-waysurveys; preparatian ofcostestimotesforsystem construdion, operation and maintenance; and preparatian of a milestone schedule far implementing the development of Lake Palestine as a water supply source for the Ciry of Dallas. Carter & Burgess is alsa part of a team preparing final geometric alignment and easement dacuments for right-of-way acquisition of over 180 parcels over the 85- mile projed length. Lake Tawakoni Pipelines Dallas, Texas In addition to upgrading the Iron Bridge Pump Statian, CaRer & Burgess was responsible for performing candition assessments far the ezisting 15 miles of parallel 72- and 84-inch water tronsmissian mains from Lake Towakani to the Tawakoni Balancing Reservair. The staff performed physical inspections of the interior of both lines and the evaluation of various alternatives for lang-term cleaning of the pipelines. The pipeline cleaning aptions included continuous chemical disinfedion with liquid chlorine and hypochlorite, periadic shock chlorinatian, and mechanical ("pigging") cleaning methods. The importance of the pipeline deaning mnnot be over stated, since a rapid increase in pipeline roughness accurs if chlorination is terminated. The increase in frictian, which results in lower C-values, dramatimlly increases pawer costs for pumping. The projed alsa included extensive hydraulic analysis of the existing pipelines, performing surge analysis on the li nes, revising the design ofthe surge protedion equipment, and camputer modeling ofthe lines in conjundion with the Iron 8
