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 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. The Utilities Department has 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.
During the design of Lift Stations 308 and 310, it was determined that during high-flow events, the gravity main system receiving flows from the Lift Stations’ forcemains 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.
City staff and Stantec analyzed the discharge of Lift Stations 308 and 310 into a gravity main system and ultimately propose forcemain improvements to address the operational challenges. In order to complete the necessary improvements, City staff requires professional consulting services to design a new connection that would route the Lift Stations 308 and 310 flows directly into an existing forcemain located outside the Rexmere Village subdivision in the Town of Davie.
The Utilities Department staff developed Project Agreement No. PA-26-013-SC with Stantec for the forcemain connection design, permitting, and bidding services for Lift Stations 308 and 310.
Staff negotiated a fee for these professional services with Stantec, that is considered fair and reasonable for the scope and complexity of the work. This project is included within the City’s Five-year Capital Improvement Program and is listed in item number 27 in Exhibit ‘A’ Scope of Services of the Continuing Services Agreement with Stantec Consulting Services Inc.
