Climate Resilient Santa Cruz: Graham Hill Water Treatment Plant Facility Improvements Project

Climate Resilient Santa Cruz: Graham Hill Water Treatment Plant Facility Improvements Project

The Proposed Project would replace and substantially upgrade the majority of the existing water treatment processes at the Graham Hill Water Treatment Plant (GHWTP) and associated infrastructure with modern facilities. The Proposed Project would improve the GHWTP to: meet current seismic, building, electrical, and fire code requirements; support the treatment of wet season water to facilitate implementation of the City’s Water Supply Augmentation Strategy and Securing Our Water Future Policy; increase the City's treatment reliability to meet current and anticipated future water quality requirements; and improve the ability to treat variable and degraded source water quality conditions, such as those associated with post-wildfire, severe storms, and droughts. Characteristics and elements of the Proposed Project include the following: reliable water treatment plant capacity, new and upgraded water treatment and related processes, new and upgraded buildings, infrastructure and site improvements, project operations and maintenance. Project construction is anticipated to commence in phases over a four-year period (from 2025 through 2029) while maintaining ongoing operations and continuous production of drinking water at GHWTP.
