Okaloosa County BOCC — August 4, 2015 — past Agenda Request 02.19.2013

BOARD OF COUNTY COMMISSIONERS AGENDA REQUEST DATE: February 19, 2013 TO: Honorable Chairman and Members of the Board FROM: Jeff Littrell SUBJECT: Polyengineering Task Order 122 DEPARTMENT: Water and Sewer BCC DISTRICT: 1, 2 & 3 STATEMENT OF ISSUE: The scope of services for this task order includes professional engineering and technical services required to design and permit a new force main from the East County Repump Station to the Eglin Main Base Sewer Pump Station. This project, in conjunction with the above-mentioned stations, will divert East County/Bluewater Bay wastewater flow from the old Niceville Valparaiso Regional WWTF, and transmit it to the new Arbennie Pritchett Water Reclamation Facility (APWRF). The Scope of Work for this task order has been developed and negotiated with Polyengineering per the terms of our Master Services Agreement to perform these services and requires approval by the Board of County Commissioners. Task Order 122 is attached for your review. BACKGROUND: In July of 2009, OCWS entered into a Memo of Understanding with Eglin Air Force Base (Eglin) to upgrade the 7th Special Forces Group (7SFG) force main in order to accommodate future wastewater flows from Duke Field, Camp Rudder, and Eglin Main Base. In the September of 2012, OCWS entered into a contract with Eglin to treat the wastewater from Eglin Main Base and to construct the necessary infrastructure to transmit the wastewater to APWRF. Included in this scope of work is for OCWS to design and construct a new sewer pump station near the Main Base WWTP (at the Northwest Gate). This pump station will transmit the Base's wastewater to the 7SFG force main, ultimately leading to APWRF. Following construction, the new Main Base Sewer Pump Station will be owned and maintained by OCWS. As a result of negotiations of the contract, Eglin allows conveyance of the wastewater from the East County/Bluewater Bay Service Area to the Main Base Lift Station. The cost to upsize the new sewer pump station in order to accommodate East County flows is borne by OCWS. The agreement allows OCWS to reduce the total force main footage required to convey wastewater to the APWRF as well as reduce the horsepower requirements needed for pumping. The benefit of this arrangement for Eglin AFB is that it reduces the size of the easement and it eliminates potential conflicts with possible future runway construction. In April of 2012, OCWS entered into an interlocal agreement with the City of Niceville and City of Valparaiso to transfer its ownership and treatment capacity at the NVOC Regional Wastewater Treatment Plant to the City of Niceville. As part of this agreement, OCWS transferred its cost sharing responsibility of the NVOC facility, and will divert of all of the flows from the East County/Bluewater Bay Service Area to the APWRF. As part of this planned diversion of flow, OCWS would need to construct a new sanitary sewer force main and repumping station to convey its flows to the APWRF. The proposed East County Repump Station is shown as Phase 9 on the attached East County Master Sewer Plan (labeled as "Proposed College Blvd Lift Station"). The sanitary sewer force main is shown as Phase 10. Note that Eglin has agreed to the alternate route for Phase 10, which allows for the alignment of the force main into the Eglin Main Base Sewer Pump Station (Phase 5). OCWS has budgeted $4.5M in FY2012-2014 for the above-mentioned force main (Phase 10), repump station (Phase 9), and upsize to the Eglin Main Base Lift Station (Phase 5). This $4.5M is funded from the $15M 2012 bank loan. Similar to the approach chosen for the design of the 7SFG force main and sewer pump station, OCWS is proposing for Constantine Engineering to design the repump station and Polyengineering to design the force main. For a project this large and complex, we feel
