BACKGROUND
PROJECT PURPOSE
• The Upper East Fork Interceptor System (UEFIS) Regional Capacity Assurance Phase 3 Report, dated November 1, 2023, recommended increased wastewater conveyance to meet the accelerated growth and increased flow projections serving Princeton.
• The Capacity Assurance recommended redirecting most of Princeton’s future flows to the Sister Grove Regional Water Resource Recovery Facility (RWRRF) for treatment through a combination of new lift stations and force mains.
• The preliminary design report recommends a 40 MGD lift station, expandable to 80 MGD, with a single 42-inch pipeline, a future lift station expansion to 80 MGD with a second parallel force main, and a future 4.9 MG peak flow storage tank.
• The planning level estimated cost for the Tickey Creek Force Main is $61,000,000.
• The planning level estimated cost for the Tickey Creek Lift Station is $78,000,000.
PROJECT COMPONENTS
Tickey Creek Force Main
• Approximately 42,000 linear feet (LF) of a single 42-inch pipeline from the new Tickey Creek Lift Station to Sister Grove RWRRF.
• Approximately 42,000 LF of fiber optic line to provide communication between the Tickey Creek Lift Station and the Sister Grove RWRRF.
Tickey Creek Lift Station
• New 40 MGD lift station, expandable to 80 MGD, with odor control system
• Flow diversion structures and discharge meter vault
• Floodplain mitigation and site development
• Replacement of the existing roof at the current Princeton Lift Station
• Demolition and closure of the original (decommissioned) Princeton Lift Station
