Exhibit A — Scope of Work Indian River County Department of Utility Services Facilities Electrical Improvements & Standby Power, Project ID 00.25.522 September 9, 2025 PROJECT UNDERSTANDING Indian River County Department of Utilities Services (IRCDUS) owns and operates consolidated water system, wastewater collection and treatment systems, and beneficial use reclaim water system that serves customers within their service boundary. Each of these systems have major supporting infrastructure that are crucial for the daily operations of the utility. Furthermore, each of these facilities rely on utility electrical power and IRCDUS-owned electrical equipment to ensure operational reliability. IRCDUS has noted components of their electrical and emergency standby power infrastructure that require improvements to maintain reliability and resiliency. Firstly, IRCDUS has noted deficiencies with the existing grounding and lightning protection at their major facilities. Thunderstorms are inherent to Southeast Florida and pose a threat to electrical infrastructure that is not adequately protected from lightning. As such, IRCDUS desires to quantify the deficiencies and restoration plan to enhance facility grounding infrastructure which will be outlined in a report that IRCDUS can subsequently utilize for the design, permitting and construction of necessary work. IRCDUS also desires to improve upon the standby emergency power conditions for each of their existing Upper Floridan Aquifer (UFA) well sites that serve the Hobart and Oslo WTPs. It is known that wells S- UR, S-2 and S-3 receive standby emergency backup power from the WTP and Well S -4R has an emergency standby generator on-site. The remaining wells, S-5, S-6 and S-7 have plugs for portable generator hook-up. The Hobart WTP provides emergency standby power to seven (7) of the nine (9) total wells, with N-7 and N-9 powered from a remote FPL service with a plug for portable generator. IRCDUS desires to investigate alternatives to improve the emergency power setup for their UFA wellfield to enhance their resiliency. Lastly, in 2022 IRCDUS completed an electrical evaluation for each of the Hobart well sites which outlined the deficiencies and areas for improvement. IRCDUS desires to refresh this evaluation and incorporate civil, process mechanical and instrumentation improvements to provide a holistic diagnosis of the Hobart wellfield, similar to what is currently being performed for the Oslo WTP under separate work order. IRCDUS desires to consolidate this evaluation into a comprehensive wellfield improvements document that can be utilized to prioritize and administer projects for the entire wellfield. The following scope of services is provided for the Facilities Electrical Improvements and Standby Emergency Power Investigation. For this scope of work, Consultant will utilize the services of C&W Engineering, Inc. for electrical engineering professional services. SCOPE OF SERVICES Task 1— Preliminary Engineering Due Diligence Consultant will perform one site visit to utility facilities. Consultant assumes up to four (4) full days of site visits will be necessary. The sites include the following: • Hobart WTP and supporting wellfield • Oslo Road WTP and supporting wellfield • Kings Highway Elevated Storage • North Beach Storage and Repump Facility K:\WPB_Civil\General\Black\Florida\IRCU\Water Facility Electrical Enhancements\20250904 - Water Facility Electrical Improvement Scope.doc Page 1
