Rovvlett Water System Improvements/ Elevated Tank Rowlett, Texas Carter & Burgess completed a number of projects as part of a major improvement of the Rowlett water system. The facilities included a new 1-MG elevated tank, 8 miles of 12 - to 24-inch water lines, telemetry system improvements and renovation of an existing 0.7 5-MG elevated tank. The Rowlett Road Pump Station included design of a 2-MG ground storage tank, 24-inch water main, yard piping, hydropneumatic tank, drainage system and connections to existing facilities. The water lines are located primarily in developed parts of the city, requiring utility coordination and construction sequencing to minimize impacts during construction. The project also included the development of a computer model of the City's water distribution system demand projections for a 30-year design period to assess future water demands. Carter & Burgess also performed an evaluation ofthe existing water distribution system capacity and pressures. Cedar Crest Pumping Station Dallas, Texas Carter & Burgess designed the 130-MGD Cedar Crest Pump Station which consists of a 96-inch diameter suction line, and 64-inch and 42-inch diameter discharge lines. The Cedar Crest Station serves two pressure planes in the City of Dallas, the South High and Trinity Heights distribution systems. The pump station's initial pumping capacity consisted of three 8-MGD single-speed pumps and two dual- speed pumps (30 MGD each at low speed and 42 MGD each at highspeed). Carter & Burgess also designed and provided witness testing of two 42 -inch Venturi meters and three 18- inch Venturi meters. A SCADA data acquisition system was designed in order to allow remote pump station operations. Landscaping to meet the City of Dallas Landscape Ordinance was also pravided. Carter ::Burgess This project required innovative design elements related to the site plan development, architectural treatments and landscaping in order to allow this high-capacity pump station, located on only 1.5 acres, to blend into the adjacent residential neighborhood which consisted of a church, residences and a golf course. The construction administration of this project included balancing the construction activities while minimizing the disruption to the surrounding community. Project activities also included surface and subsurface investigations, analysis of design alternatives, pump station hydrauliC design, surge analysis, structural design requirements based on specific site and soil conditions, pump station configurations, security systems design, resident construction administration services, and electrical! instrumentation, mechanical design, architectural design, and smoke detection and removal system design. Circle T Ranch Fidelity Water Master Meter & Water Line Along SH 114 Fort Worth, Texas Hillwood Development Corporation officials plan to supply Fidelity Investments at Circle T Ranch with water from the City of Fort Worth. " Carter & Burgess employees designed the master water meter and water line along Texas SH 114 that will bring the water from the city of Fort Worth into the planned community. 7
