EXHIBIT A <br />INDIAN RIVER COUNTY UTILITIES DEPARTMENT <br />WORK ORDER No. 1 <br />SCOPE OF SERVICES <br />West Regional WWTF Clarifier Improvements <br />IRCDUS PID 22.23.556 <br />Background <br />The Indian River County Department of Utilities Services (County) owns and operates the West <br />Regional Wastewater Treatment Facility (WRWWTF). The WRWWTF was originally constructed <br />in 1994, including two secondary clarifiers. Clarifiers Nos. 1 and 2 each consist of a prestressed <br />concrete basin provided by Crom Corporation (Crom) and a sludge collector mechanism provided <br />by Walker Process Equipment (Walker). The Clarifiers were operated until the WRWWTF was <br />expanded in 2012. Following the expansion, neither clarifier was necessary for the WRWWTF to <br />meet capacity requirements. The clarifiers were taken offline but they were not <br />decommissioned. The clarifier mechanisms remain in place, but they have not been operated, <br />maintained, or repaired since 2012. Moreover, the clarifier mechanisms are well past the normal <br />expected service life of wastewater clarifier mechanisms. <br />f� <br />Figure 1. Condition of Clarifier Mechanisms <br />Current and anticipated future growth in the West Service Area has brought about the need for <br />additional clarifier capacity at the WRWWTF. Accordingly, the County seeks to restore Clarifiers <br />1 and 2 to operation, but the mechanisms must be replaced before the clarifiers can be brought <br />online. <br />The County has standardized on Crom for basins and tanks and on Walker for clarifier <br />mechanisms at all County wastewater facilities. Atkins has arranged for Crom to inspect the <br />existing basins. It is anticipated that Crom will either confirm that the basins can be reused in <br />their current condition, or they will recommend minor repairs to the basins. <br />1 <br />
