Regular Agenda Item INDIAN RIVER COUNTY, FLORIDA DEPARTMENT OF UTILITY SERVICES Date: November 29, 2018 To: Jason E. Brown, County Administrator From: Vincent Burke, PE, Director of Utility Services Prepared By: Arjuna Weragoda, PE, Capital Projects Manager Subject: Barrier Island Reclaimed Water Main System Analysis DESCRIPTIONS AND CONDITIONS: Indian River County has historically provided reclaimed water (a.k.a. reuse) to area golf courses for irrigation. Recently, as part of the capital improvement plan implementation outlined in the Reclaimed Water Franchise Agreement between the Town of Indian River Shores (Town) and Indian River County, the expansion of the County's reuse system evaluation is a requirement. However, this process began seven years ago. As part of that process to provide reclaimed water service to Indian River Shores and the North Barrier Island (south of SR 510), on December 13, 2011, the Indian River County Board of County Commissioners (BCC) approved Work Order No.1 to Schulke, Bittle & Stoddard, LLC. Only the hydraulic analysis portion of Phase I of that work order was complete when the project was halted in March 2012 due to the termination of the City of Vero Beach (City) water and wastewater utilities purchase agreement between the City and Indian River County, and the Town signing a franchise agreement with the City for the City to provide reuse. ANALYSIS: Staff reached out to Schulke, Bittle & Stoddard, LLC (SBS) to perform an engineering feasibility analysis to run a pressurized reuse transmission main along the A1A corridor fed from a storage and repump station at the Sea Oaks Wastewater Treatment Plant (WWTP) site. Given the tight constraints of existing infrastructure within the AIA corridor, in order to accurately determine the feasibility of a reuse transmission main, SBS re-evaluated the corridor prior to submitting a proposal. As part of the evaluation, SBS determined the need for extensive existing utility locates in, around, and under the AIA right-of-way corridor. This analysis will be accomplished by SBS securing an underground utility contractor to physically locate the existing underground utilities via pot holing. Once the underground existing utilities are located, the horizontal and vertical information will be surveyed. Therefore, approximately 52.3% of the cost of the subject work order is attributed to locating the existing underground utilities within the A1A corridor in order to accurately determine if a reuse main can be installed. The work order has been provided in accordance with the Continuing Contract Agreement for Professional Engineering Services with SBS dated April 17, 2018. The scope is more specifically described in the attached Work Order No. 3. The total negotiated cost for Work Order No. 3 is a total sum amount of 113.
