MULTI-PROJECT FEATURE WATER the McNutt Creek Basin. The first phase begins at the Brushy Creek Regional Wastewater Treatment Plant, south of U.S. Highway 79. It extends about 8,700 feet northeast to the north bank of McNutt Creek. This phase also involves building facilities for transfering the flow into the Regional Wastewater Treatment Plant. In the preliminary engineering phase, KFA decided that the most cost-effective way to build the project was with an open-cut construction of the interceptor with a lift station at the wastewater treatment plant. Among the challenges the company faced were creek crossings at each end of the interceptor, requiring the center portion of the alignment to be more than 45 feet deep. KFA investigated various methods for excavating trenches this deep, evaluated eligible pipe materials and discussed the situation with several contractors to develop alternatives for installation. When it was determined that benching would be required to excavate the trench, and that the work therefore would be much more expensive, KFA decided to install the interceptor using tunnel installation. The project had a strict design schedule, so timely responses to numerous design changes were critical, said KFA project manager Tom Owens. KFA met every project milestone submittal date and completed the project under budget. “KFA utilized our relationship with several contractors and our cost database,” Owens said. “We performed in-house constructability reviews and kept abreast of current industry cost trends to accurately forecast the estimated construction cost.” I n rapidly growing Williamson County, Texas, there are 9,064 acres of largely undeveloped land known as the McNutt Creek service area. When it became clear the city would need a large capacity wastewater interceptor to serve the region’s future development, the site became the location for the McNutt Creek Wastewater Interceptor. Austin-based K. Friese & Associates, Inc. (KFA) provided design, permitting, bid phase and construction administration services for the first phase of the interceptor— which will provide the furthest downstream segment of a chain of interceptors designed to provide gravity service to Wastewater Interceptor ProveS vIable SoluTIon K.
