Lake Texoma Pipeline Extension & CMAR
Steve Long, P.E., Program Manager, North Texas Municipal Water District
David Burkhart, Senior Project Manager, Garney Construction
Jeff Payne, Principal, Freese and Nichols Inc.
The North Texas Municipal Water District’s (NTMWD) Lake Texoma Water Supply Project conveys raw water via a 30-mile-long, 72” diameter pipeline from Lake Texoma, south to a discharge point at Sister Grove Creek and then into Lake Lavon. When zebra mussels invaded Lake Texoma in 2009, NTMWD began transferring water from the infested Red River basin to the un-infested Trinity River Basin, until the US Corps of Engineers ordered that the pumping operations cease until a solution to the spread of the destructive species could be found. In October 2011, with other supplies stressed by almost two years of droughts, NTMWD embarked on a $309 million project to re-establish access to Lake Texoma raw water by extending the system another 47 miles south to bypass Sister Grove Creek and Lavon Lake, and connect directly to the head works of four water treatment plants in Wylie, TX.

NTMWD’s CFRP Large-Diameter Water Rehabilitation
Kyle Sanderson, P.E., Project Manager/Associate, Kimley-Horn & Associates Inc.
This presentation will discuss the North Texas Municipal Water District’s Wylie-Rockwall-Farmersville Pump Station improvements project to increase the discharge pressure in about 2 miles of the existing 36” water line, from 100 to 150 psi. Following evaluation of the different trenchless technologies, CFRP rehabilitation was selected in locations totaling 910 LF, where it was not feasible to construct a new line. The project also included 970 LF of hand tunnel with tunnel liner plate, 570 LF of guided auger bore and 48” steel casing pipe to aid in creek and TxDOT crossings, and an extended installation underneath the median of Brown Street within the City of Wylie. Challenges faced throughout the process, such as sequencing and structuring the work to minimize downtime and costs, and to clarify contractor/subcontractor responsibilities will also be addressed.

He has a Civil Engineering degree from Texas A&M University.

Rehab System for Pipe Maintenance Operations
Mark Knight, Professor, University of Waterloo
As North American water utilities move from a repair and maintenance operations mode into capital improvements and replacement programs for their aging buried pipes, they face daunting capital programs and the associated financial challenges. There is a need for innovative thinking that can reduce the tremendous cost and duration of multi-year capital programs. This presentation makes a case for the innovative deployment of several leading-edge trenchless technologies to create a “rehabilitation system” that allows trenchless renewal to be accomplished quickly, economically and sensibly. Water utilities willing to embrace new technology systems can extend the lives of their buried drinking water pipes for decades using current operations and maintenance budgets.

Arlington Pre-Chlorinated Pipe Bursting
Jessie Allen, Senior Engineer of Operations, Arlington Water Utilities
Al Meschke, Business & Educational Director-Texas, Murphy Pipeline Contractors
Arlington Water Utilities (TX) maintains over 1,440 miles of water mains in the distribution system, including 588 miles of existing asbestos cement (AC) pipe. In 2015, 72% of the 533 water main breaks were on AC water mains. Using an innovative approach geared towards reducing customer impact, minimizing capital spending and reducing operational costs, Arlington selected pre-chlorinated pipe bursting to install new HDPE pipe. Murphy Pipelines, which specializes in this technology, was awarded the project. To date, work has progressed replacing more than 13,000 LF of existing 6” AC water main with new 8” HDPE pipe. The majority of the work is in typical residential neighborhoods with a history of frequent water main breaks. Minimum construction related customer complaints have been recorded.

allenJessie Allen, P.E., is the senior engineer of operations for the City of Arlington Water Utilities Department. She is responsible for the implementation of the Water Department’s Capital Improvement Program for water and sanitary sewer pipeline design and construction projects. She has a B.S. in Civil Engineering from Texas Tech University.

Columbus, GA, Requires Zinc-Coated DIP
Tom Horn, Manager of Engineering, Columbus Waterworks
Columbus Water Works, just like nearly 700 members of the DIPRA 100-year and 150-year clubs, believes that “you get what you pay for.” Iron pipe, made of either gray or ductile iron, has a very favorable history of sustainability in the Columbus system. Some lines have been in service over 100 years. The line with the greatest duration of continuous service was installed in 1885.  With the objective of sustaining their piping system beyond 200 years, Columbus determined zinc coating of its DIP was a technically sound and financially responsible measure. This presentation is a case study of Columbus’ cost justification process based on the passivating benefit of zinc coating, the knowledge of how it works to protect the underlying pipe, and the moderate pricing differential of zinc coated ductile iron pipe.

hornTom Horn joined Columbus (GA) Waterworks in 1992 with experience in the consulting engineering field. Currently he serves as CWW’s regional and client service manager, and before that was manager of Engineering for 15 years. He earned a B.S. from Southern Technical Institute, Marietta GA.
