BACKGROUND Indian River County Department of Utility Services (County) operates the Hobart Water Production Facility (WPF) to provide potable water service to its customers. The WPF has a capacity of 11.4 MGD and an average daily flow of approximately 7.0 MGD. The raw water source for the WPF is groundwater from the Upper Floridan Aquifer. At the Hobart WPF, the raw water first passes through mesh strainers before it undergoes chemical pretreatment, membrane treatment, degasification and the addition of chemicals for stabilization, disinfection, remineralization, and pH and alkalinity control of the treated water. The Hobart WPF receives water from nine (9) groundwater wells located on and off the WPF site. The raw water manifolds into two (2), 20 -inch diameter piping segments. Each segment is reduced in size to 16 -inch diameter to feed a stainless -steel strainer system, manufactured by Hydac International. The strainers are used to remove coarse sand and other larger particulates before manifolding into a single 24 -inch raw water pipeline, which contains a pretreatment static mixer just before entering the membrane treatment process building. The strainers are self-cleaning and initiate a backwash sequence anytime the differential pressure across the strainer mesh exceeds a preset value. Operational staff at the Hobart WPF have noted issues with the existing strainer system. The primary issue is excessive pressure loss when the strainers are operating at higher flows (typically in excess of 7.5 MGD). The actual pressure loss across the strainers greatly exceeds the manufacturer's estimates, and this excess pressure loss results in low feed pressure to the membrane feed pumps, particularly during backwashing. As the North service area continues to grow, the hydraulic limitations of the strainer system at higher flows has become more apparent and compromises the WPF operation. Additional concerns with the pneumatic valve actuators and long lead times for replacement parts also warrant consideration. Tetra Tech has compiled information provided by County staff as part of another project, and has preliminarily identified possible hydraulic "bottlenecks" in both the strainers and downstream piping. The County requested a more in-depth evaluation of the strainer system in order to identify root cause(s) of the hydraulic limitations of the strainers/raw water feed at the Hobart WPF and provide options for improving the raw water feed pressure to the RO feed pumps. Additionally, Tetra Tech will investigate the current design of the strainers, and the available options from two manufacturers under consideration (Hydac International and R. P. Adams) and develop design alternatives for the County's consideration. The design alternatives will include preliminary design criteria and budgetary costs and will be presented in a technical memorandum format. Upon acceptance of the technical memorandum by the County, the selected alternative will be further developed with final design and the development of contract documents for a sand strainer project at the Hobart WPF. Permitting, bidding and construction administration services will also be provided for implementation of the design at the Hobart WPF. JCR/pt/IRCDUS Project ID 12.24.504 Tt #2008P Indian River -1- 8/7/26 OTFTRA TFCH The professional services described herein will be performed in accordance with the Continuing Contract Agreement for Engineering Services, dated May 2', 2023 between Indian River County and Tetra Tech, Inc.
