Scheduled for completion in August, the South Mountain Water Facilities pipeline will increase drinking water capacity to the community of Ahwatukee Foothills, a rapidly growing south Phoenix suburb, by connecting the Ahwatukee Foothills reservoir with the South Mountain reservoir. The $58-million pipeline project requires two pump stations and 17 mi (27 km) of prestressed-concrete cylinder pipe. Segmented into seven reaches, the project's most intricate section involved digging a tunnel through a mountain that is also the site of a major city park. Additionally, the presence of soil within what had been expected to be an all-rock tunnel required changes to the initial design and complicated the process of selecting an appropriate tunnel boring machine.
