CARROLLTON AWARDED 2010 PUBLIC WORKS PROJECT OF THE YEAR AWARD

Carrollton has been awarded the 2010 Public Works Project of the Year Award by the Texas Public Works Association (TPWA) in the Environment category with a project cost between $10 and $100 million. The award is for the North Transmission Water Line project that consisted of the construction of a seven mile long water pipeline originating at Dallas Water Utilities’ (DWU) Elm Fork Water Treatment Plant located near the center of Carrollton and ending in the northeast section of the City.

The line was constructed in accordance with the City’s 2001 Water Master Plan which identified deficiencies and needed improvements to meet future demands. The new pipeline was designed and constructed to satisfy the needs of three cities, Carrollton, Lewisville and The Colony. By including the Cities of Lewisville and The Colony in the project, future additional water lines through Carrollton to serve these cities have been avoided in already crowded right-of-ways. “It was a challenging project that involved the coordination of several agencies such as DWU, North Texas Tollway Authority, the DGNO Railroad, two other cities, and two contractors over a seven mile route across three of the City’s busiest streets,” said Cesar Molina, Carrollton’s Director of Engineering.

A professional services contract for the design of the North Transmission Water Main was awarded and an Interlocal Agreement between the three cities was approved in August 2004. The project was divided into four phases to make it more manageable and to enable more contractors to bid on the project. Birkhoff, Hendricks & Conway, LLP provided professional engineering services while S.J. Louis Construction of Texas was awarded construction of three of the four segments and Mario Sinacola & Sons was awarded construction on one segment of the line. The design for each segment was completed between May and November 2006, construction began in April 2007 and the project was completed in April 2009.

The North Transmission Water Line has been in operation since March 2009 and the new water line provides for more efficient operation of Carrollton’s water distribution system. Energy costs have been reduced by $450,000 annually as DWU supplies water directly to the north part of the City under the new alignment. With the new construction, Carrollton’s Parks Department has planted trees and landscaping in adjacent medians making the cityscape along the water transmission line more attractive and sustainable. “The line is operating smoothly and is saving tens of thousands of dollars in annual pumping costs. We appreciate the opportunity to receive this recognition,” commented Molina.

Molina, along with Thomas Geier, Capital Improvements Manager will be recognized for this award at the TPWA Annual Conference Awards Banquet on Friday, June 25. For more information about the North Transmission Water Main, call 972-466-4230.
