Task 2 — Facility Inspection and Data Review <br /> This task involves the review of existing information about the North Regional WWTF, <br /> including its current condition, for use in establishing alternative concepts for its upgrading <br /> and expansion . <br /> Subtask 2 . 1 — Existing Plant Condition Assessment. Conduct a thorough inspection of <br /> the existing North Regional WWTF focusing on the condition of existing structures and <br /> equipment. The objective of the inspection will be to identify those facilities which are in <br /> good enough condition to remain if they can be incorporated into the North Regional <br /> WWTF expansion design at reasonable cost. <br /> Subtask 2. 2 - Data Compilation and Review. Review existing data and information <br /> available from Indian River County regarding the North Regional WWTF site . This <br /> information is likely to include, but is not necessarily limited to, the following: <br /> • Legal description and boundary survey of the North Regional WWTF site and <br /> adjoining land owned by Indian River County that could be used for North Regional <br /> WWTF expansion. <br /> • Copies of previous reports, permit applications , design documents , record drawings , <br /> and other information relevant to prior work at the North Regional WWTF . <br /> • Operating data for the North Regional WWTF prior to its being taken off-line in <br /> 2000, including records regarding the disposal of treated effluent, if available. <br /> • Any additional site operating data, such as water levels in groundwater monitoring <br /> wells, which may have been collected on an on-going basis after the North Regional <br /> WWTF was taken off-line in 2000 . <br /> In addition, Indian River County will be collecting current influent flow and water quality <br /> data at the North Regional WWTF for a period of at least 30 days in support of this project. <br /> BC will review this data and use it to perform hydraulic modeling and modeling of <br /> alternative treatment process designs during preparation of the PER in Task 5 . <br /> Task 3 — Surveying Support Services <br /> The original boundary and topographic survey of the North Regional WWTF site was <br /> performed in support of the 1988 design of the plant. In 2000 , an updated topographic <br /> survey of a significant portion of the existing site was completed by Carter & Associates <br /> during design of the pumping station and transmission main improvements at the plant. <br /> This data is assumed to still be valid since no additional work at the plant has been done <br /> since that time . However, additional topographic data on adjacent land and other survey <br /> information on and around the existing plant site will be needed for the PER and the <br /> subsequent detailed design phase of the project. <br /> S: \ 041077\ IRC North Regional WWTF Expansion\ Exh bit A_revl .doc <br />
