Background:
The Utilities Department owns, operates, and maintains 216 lift stations throughout the utility service area. Lift Stations No. 308, 310, 405, and 408 require rehabilitation as part of the Department’s ongoing efforts to renew and replace aging assets within the wastewater system. These lift stations are wet pit/dry pit configurations that are near the end of their useful life and present significant maintenance challenges for the Department. These lift stations require staff to enter tight, deep, confined spaces for maintenance purposes and some of these have site access issues due to the layout and location of the stations adjacent to residences. Due to these issues, the City planned to retrofit the existing wet wells to accommodate new above-ground wet well mounted wastewater pumping stations.
On September 26, 2023, the City Commission approved Project Agreement No. PA-23-029-SC, pursuant to Resolution No. 21-47-23-B, between the City and Stantec Consulting Services Inc. for design, permitting, and bidding services related to improvements at Lift Stations 308, 310, 405, and 408.
On August 28, 2025, the City Manager’s Office approved a 180-day extension to Project Agreement No. PA-23-029-SC, at the request of Stantec, to allow additional time for completion of plan review and permitting. This extension extended the agreement term through March 17, 2026. Currently the design of Lift Stations 405 and 408 have been completed, and these Lift Stations are expected to be bid within the next 90 days.
During the design of Lift Stations 308 and 310, it was determined that during high-flow events, the gravity main system receiving flows becomes overloaded, resulting in sanitary sewer operational challenges within the adjacent manholes. As a result, the design of improvements for Lift Stations 308 and 310 was temporarily placed on hold. After analysis by City staff and Stantec, it was determined that improvements to the forcemains downstream to these lift stations were necessary.
To align the design schedule of Lift Stations 308 and 310 and to accommodate the time necessary to complete design and permit of new forcemains required to connect Lift Stations 308 and 310 to the City’s existing forcemain system located outside the Rexmere Village subdivision within the Town of Davie, an extension to the Project Agreement is needed. The forcemain design services will be completed under a separate Project Agreement.
This agenda item requests approval of the First Amendment to extend Project Agreement No. PA-23-029-SC with Stantec Consulting Services Inc. through May 18, 2028 at no additional cost to the City, to allow for completion of the design phase, and continuing through to the bidding phase services.
