BACKGROUND
The use of the Construction Manager At-Risk (CMAR) project delivery method has been selected and authorized for the Texoma Raw Water Pipeline No. 2 and Texoma Raw Water Pipeline to Leonard WTP Pipeline as a single construction contract. An Owner’s Advisor (OA) was selected for this CMAR project due to its large scale and the limited size of NTMWD’s staff. The OA will provide the additional expertise needed to effectively manage the CMAR process, including design review, cost evaluation, and coordination between the Owner, Engineer, and Construction Manager. NTMWD will rely on the OA to facilitate communication, track progress, and ensure the CMAR team’s work aligns with project goals. This collaboration helps maintain quality, costs, and keeps the project on schedule while allowing NTMWD to make informed decisions throughout each phase.
PROJECT PURPOSE
The Texoma Raw Water Pipeline No. 2 increases the capacity of raw water transfer from Lake Texoma to the NTMWD treatment facilities. To meet projected future demand, a new parallel 84-inch transmission line from Lake Texoma to the Howe Balancing Reservoir is needed by 2029. With the existing 72-inch line, the proposed 84-inch parallel line, and a separate Texoma Pump Station Improvements project, the District will have the ability to deliver up to 220 million gallons per day (MGD) of raw water from Lake Texoma of which 120 MGD would be conveyed to the Wylie WTP complex, 70 MGD diverted to the Leonard WTP, and approximately 30 MGD delivered the City of Sherman.
To increase the utilization of raw water rights, water from Lake Texoma will be blended with raw water from Bois d’Arc Lake at the Leonard Water Treatment Plant Facility. This additional supply will fully utilize the planned future treatment plant capacity of 280 MGD. Texoma to Leonard Raw Water Pipeline will also be an 84-inch gravity line connecting to the existing Texoma Raw Water Pipeline south of Howe Reservoir to convey water to Leonard Terminal Storage Reservoirs.
