Reingold, County Attorney ATKINS EXHIBIT A INDIAN RIVER COUNTY UTILITIES DEPARTMENT WORK ORDER No. 9 SCOPE OF SERVICES North County Inline Pump Station Evaluation IRCDUS PID 21-23010 Background Increases in current and anticipated future growth in the north end of the County's service area have resulted in the need to address the replacement of the master lift station for this area, Lift Station 203. In October 2022, Indian River County Department of Utility Services (IRC) requested that Atkins provide technical services to evaluate the option of replacing the existing master pump station, Lift Station 203, with an above -ground booster pump station, Capital Improvement Project Identification Number (PID) 21-23010. Lift Station 203 is located at the decommissioned North Wastewater Treatment Facility (WWTF) and consists of two submersible pumps located in the equalization tank that was part of the abandoned North WWTF. The equalization tank is open to atmosphere, causing major odor issues, and there is concern about the structural integrity of the concrete tank. For these reasons, Lift Station 203 is considered unsuitable for expansion or rehabilitation. Figure 1 shows the existing pump station and tank configuration. Figure 1. Lift Station 203 at the North WWTF IRC would like to replace the deteriorating existing pump station with an in-line above -grade wastewater pump station similar to the configuration of IRC's Lift Station 89. The new pump station will address the increase in pump station capacity as well as the odor issues associated with the current pump station. Lift Station 203 functions as a master pump station, collecting flows from three areas. From the north, there are 59 lift stations that feed into a 24" force main which reduces to a 12" force main 1 Exhibit /�TKINS IRC North County Inline Pump Station Evaluation just north of the EQ tank (to take advantage of an existing pipe at the abandoned North WWTF). The next area sending flow is a lift station located at the IRC's North Water Treatment Plant that transfers waste through a 6" force main that connects to the 12" force main just ahead of the EQ tank. From the west, flows from Fellsmere and SR 510 feed into a 12" force main that empties directly into the EQ tank. The total flow into the EQ tank is approximately 2 million gallons per day (mgd). Lift Station 203 transfers this wastewater directly to IRC's Central Wastewater Treatment Facility (WWTF). The Atkins team will assist IRC Staff in the review of the hydraulics of the existing collection system, verify the design criteria for the master pump station, and determining a location best suited for efficient operations and maintenance of the facility. The results of the activities will be discussed in a series of Workshops with a goal of finalizing the path forward for meeting the requirements for the pump station. Scope of Services This Scope of Services is for technical services associated with determining the replacement options for Lift Station 203. Upon Notice to Proceed, the Atkins Team will provide professional services associated with the investigation into replacement options, culminating in a series of Workshops to document the recommendations and decision processes. Task 01 Project Management This task consists of overall management of the Project including contract administration, budget management, invoicing, monthly status reports, project scheduling, facilitating and coordinating internal design meetings, and coordination with the Atkins's subconsultants. It is anticipated that Atkins will facilitate three in- person meetings with Staff to conduct field visits, review draft concepts and to receive review comments. In addition, the Atkins Team will facilitate up to four monthly project progress meetings with the County, including scheduling, preparing agendas and distributing meeting minutes. Deliverables: Invoices, meeting and Workshop coordination, facilitation of meetings and Workshops, meeting agendas and summaries. Task 02 Data Collection The Atkins Team will collect and review data and information provided by the County for the work to be completed and request any information that may be missing. Any information provided by IRC in hard copy will be scanned for project use. The hard copy along with an electronic version will be returned to the County for their records. A summary of the anticipated data is listed below. • Existing In -Line Booster Station As-Builts, including wetwell and float settings • Existing Pump O&M Manuals, including pump curves • Existing Force Main As-Builts • Roadways and Utility Data in Proximity 2 Exhibit A IRC North County Inline Pump Station Evaluation ATKINS • New infrastructure added since the 2015 Wastewater Hydraulic Model update, including pipe and valves • GIS shapefiles of the collection system • Projected wastewater flows that are anticipated in the LS 203 basin such as planned unit developments, commercial/industrial developments and/or populations projections. • New lift station operations (pumps on/off) • Previous Geotechnical Reports, Condition Assessments, or other studies performed within the abandoned North WWTF site. • Operational SCADA data for all lift stations in Lift Station 203 basin showing pumping start times, durations, and flow rates (15 -minute intervals). Deliverables: Data request memo. Task 03 Hydraulic Evaluation The hydraulic model of the existing collection system will be updated to the latest software version and any new lift stations and piping will be added. Existing flows will be updated in the model based on geocoded water demands, pump station flows, and influent flows at the Central WWTF. Current peaking factors will be determined through evaluation of SCADA data. Future flows through 2045 for Lift Station 203 will be determined by review of anticipated future development and anticipated land use plans. The results of the modeling effort will be summarized and presented in a Workshop with the County for verification of results with actual field operations. Following the meeting, the model will be updated to address County comments. The model will then be utilized to determine the anticipated range of flows and pressures required for the new pump station. System curves will be created for use in pump selection. Along with Workshop meeting notes, tables and figures summarizing the results from the finalized model will be submitted to the County for their records. Deliverables: Workshop with County Staff to discuss and verify the results of the updated model. Workshop summary, including final model tables and figures. Task 04 Equipment Selection and Operations The Atkins Team will utilize the results of the hydraulic model to determine the capacity of the proposed lift station and determine if an emergency wet weather bypass system is required. To meet the anticipated need for bypass during extreme weather, a bypass to the equalization tank has been considered. Pending hydraulic model results, the volume and frequency of bypass operations will be better understood and the potential operations for bypass and recovery can be addressed. Atkins will facilitate a Workshop to discuss options with County Staff and finalize pump station operations. The results of the Workshop will be documented in a meeting summary. Atkins will contact pump vendors to discuss the intended 3 ExhibitA IRC North County Inline Pump Station Evaluation ATKINS operation of the pumps and verify pump, motor and drive selections. Preliminary Cost Proposals from vendors will be requested and provided to the County Deliverables: Workshop with the County to review pump station design criteria, including bypass capacity and operations. Workshop summary and vendor cost proposals. Task 05 Pump Station Siting and Preliminary Layout Atkins will determine pump station components, including booster pumps, drive types, piping configurations, backup generator and fuel tank, and control room based on the decisions made at the Pump Operations Workshop. Atkins will review options for utilizing portions of the abandoned North WWTF to house components of the pump station such as the electrical room and control room. A draft layout will be discussed with IRC Staff in a virtual meeting prior to creating a preliminary site plan that includes the proposed yard piping, new pump station and associated components including bypass operations. A conceptual site plan will be submitted to the County via email. Deliverables: Submittal of a draft conceptual site plan, followed by a virtual meeting to discuss County comments. An updated site plan will be submitted to the County via email.
