Overview: The Western Cary Water Storage Tank Project was first considered in the 2000 water system master plan in order to fulfill the anticipated storage demands that would be needed by 2018. Since that time, the Town’s water system has experienced significant changes such as the merger with the Town of Morrisville’s water system and the growth and expansion of the pipe network in the western part of Town. As a first phase of this project, the (most recent) 2008 water system master plan was examined and recommendations for amendment were made so the overall efficiency of the water system can be improved. Specifically, issues such as maximizing usable storage in all tanks, transferring water when needed between neighboring systems, the ability to provide more water into the central pressure zone, and modifying pressure zone boundaries will all be included in the project. When completed, the Western Cary Water Tank will ultimately provide additional storage for the water system, help maintain system pressure, reduce the demands on the transmission mains during peak flow conditions, and provide reserve capacity during fire fighting or system maintenance activities.

Construction of an approximately 2-million gallon water storage tank near the intersection of NC Highway 55 and Good Hope Church Road. In order to distribute the water from the tank and strengthen the piping network, 9,500 feet of waterline along Good Hope Church Road, Jenks Road and other locations will be installed. The project will also include various pipe modifications along NC Highway 55 between Jenks Road and Kit Creek Road in order to modify the pressure zone boundary.

Status: Preliminary engineering work is underway and will continue until the fall of 2016. Construction is anticipated to begin in early 2017.
