Public Works Project of the Year
American Public Works Association
The American Public Works Association selected the Texoma-to-Wylie Water Treatment Plant Pipeline Extension as a 2016 Public Works Project of the Year in the Disaster or Emergency Construction Repair - more than $75 million category.
The project is a response to the presence of invasive zebra mussels in Lake Texoma, the source of 25 percent of the raw water supply for the North Texas Municipal Water District. To prevent the mussels from spreading further, NTMWD is not allowed to pump the water into the Lake Lavon watershed. By connecting Lake Texoma directly to the Wylie Water Treatment Plant, this project will restore access to the critical water supply and carry 280 million gallons of water a day.
The project includes 48 miles of 84-inch and 96-inch pipeline, design of a 240-million-gallon earthen balancing reservoir, and modifications to the four existing water treatment plants to facilitate the connection of the new system. Freese and Nichols completed the fast-track design in 13 months so that the water supply can be brought online within 30 months. Our team coordinated eight design teams and multiple survey and right-of-way acquisition teams to deliver the project on schedule.
