SUBJECT
recommendation
Authorize funding in the amount of $2,737,600 to AECOM Technical Services, Inc. for an engineering services agreement (ESA) for preliminary design of the Leonard to Princeton Pipeline project.

PURPOSE
Projected growth in the North System is expected to challenge the current capacity to deliver water efficiently and reliably from the Wylie Water Treatment Plant to the City of Princeton. The purpose of this project is to provide a reliable second source of treated water into the North System from the Leonard Water Treatment Plant to meet the projected demands.

BACKGROUND
The current and forecasted growth within the North and East Systems increases the demand and necessitates additional capacity be supplied by the Leonard Water Treatment Plant (WTP) to supplement Wylie WTP in the near-term demands.
PROJECT PURPOSE
• This project was identified in the 2021 Water Transmission System CIP Update as demand projections for the City of Princeton (City) are expected to double by 2030 and continue to steadily increase by 2050 to the Princeton Delivery Point No. 2A. To meet these forecast demands, an additional pipeline is needed beyond the existing 14-inch and 24-inch pipelines originating from the Wylie Water Treatment Plant currently serving the City.
• Enhance resiliency and redundancy in the North system by secondary supply from the Leonard Water Treatment Plant.
• The pipeline is planned to be completed and in service by 2031.
• The planning level estimated construction cost from the 2021 report is approximately $28,480,000. The Engineer will review and provide an updated estimate during the preliminary engineering phase.
PROJECT COMPONENTS
• Design approximately 28,000 linear feet of 48-inch diameter pipeline from a new connection on the existing Leonard Treated Water Pipeline (TWPL) No.1 to a tie-in location near the Princeton Delivery Point No. 2A.
• Alignment study to develop viable routes and recommend a final alignment for the pipeline.
• Preliminary engineering design of the pipeline, including material, sizing, and appurtenance design, tie-in location on the existing 84-inch pipeline, and future connection to the parallel Leonard TWPL No. 2.
• Hydraulic analysis, including transient modeling and water age analysis
• Recommendation for cathodic protection system
• Recommendation for Supervisory Control and Data Acquisition (SCADA) updates.
• Land Acquisition services and preparation of easement documents (Right-of-Entry (ROE), field notes, appraisals, offer letters, condemnation hearings) for the pipeline corridor.
BASIC SERVICES
• Project Startup, Coordination, Meetings, and Project Administration
• Alignment Study
• Preliminary Design Report and 30% Plans with development of a preliminary Opinion of Probable Construction Costs (OPCC)
• Electrical and Instrumentation and Controls (I&C)
SPECIAL SERVICES
• Topographic and Boundary Survey Services
• Environmental Evaluation Services
• Cultural Resources / Archaeological Evaluation Services
• Right-of-Way (ROW) and Easement Acquisition Support Services
CONSULTANT SELECTION PROCESS
• A total of five engineering firms were interviewed for the Leonard Treated Water Pipeline Segments D and E and this project. AECOM Technical Services, Inc., was deemed as the most highly qualified firm for this project.
