This project is a response to two emergencies: the presence of invasive zebra mussels in Lake Texoma, and the loss of 25 percent of raw water supply due to drought.
Pumping from the Oklahoma border to North Texas posed the threat of mussel infestation in Lake Lavon. The North Texas Municipal Water District responded quickly with a commissioned study of possible solutions to restore the raw water supply. The only practical method required a pipeline to transport water from Lake Texoma directly to NTMWD's treatment plant in Wylie.
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. The design phase was paired with selection and contracting with a Construction Manager at Risk (CMAR), enabling materials and work that required more time in the schedule to be completed first. This process saved at least three months of valuable time compared to a traditional construction schedule.
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. This project will restore access to the critical water supply and carry 280 million gallons of water per day.
The Texoma-to-Wylie connection has been recognized as an award-winning project by several organizations.
