Emergency Lifeline Water Supply for San Angelo, Texas

The City of San Angelo (City) faces immediate water supply challenges and the need to make critical decisions to secure long-term reliable water supplies is now. Once reliable supplies, in the form of lake and surface waters, are now threatened. An immediate solution is required to help the City preserve access to these water supplies while meeting regulatory and customer needs. The Hickory Aquifer located in the nearby McCulloch County, where the City owns existing water rights and represents a viable and consistent source of water to the City, is the solution. The major elements of the Hickory Water Supply Project include the development of a groundwater well field, pump station, water transmission main, and water treatment for the radium-containing groundwater. This paper focuses on the route study, water quality implications, and pipe materials evaluation for the transmission main consisting of approximately 63-miles of 30-inch diameter pipe.
