Georgia Association of Water Professionals Annual Conference

Tunneling Versus Pumping Cost Effectiveness for Handling 45 MGD Lift Station Expansion
Presented by Gresham Smith’s Wayne Hunter, P.E., Tim O’Brien, P.E., and Brian Fiske, P.E., and North Texas Municipal Water District’s Donna Long and Scott Hoelzle

The North Texas Municipal Water District (NTMWD) is a Regional Water, Wastewater, and Solid Waste Services provider to 80 cities and districts lying in 10 counties in north central Texas. NTMWD’s service area includes some of the fastest growing cities in the US and NTMWD’s service demands are expected to double by year 2050.

In 2019, NTMWD system planning confirmed that the BCLS would soon reach capacity and that improvements to the BCLS should accommodate an additional 45 MGD in addition to the existing 30 MGD served by the existing system. NTMWD engaged Gresham Smith to provide a comparative evaluation of  three options to define the best infrastructure investment option for addressing the required improvements to the BCLS.

This presentation will highlight how the team approached the project, how they settled on the Buffalo Creek Interceptor Tunnel, and what challenges they faced along the way.
