Home My WebLink About2022 10 24 Consent 301 - Lift Station 7W Improvements • CONSENT AGENDA ITEM 301 Incnrinreted CITY COMMISSION AGENDA I OCTOBER 24, 2022 REGULAR MEETING 1959 TITLE Lift Station 7W Improvements SUMMARY Lift station 7W (LS 7W). LS 7W is a master lift station that receives direct flow from 4 lift stations and is downstream of 6 additional lift stations. The flow from this lift station is pumped directly to the West Water Reclamation Facility. This lift station was identified as a critical lift station in the 2022 Wastewater and Reclaimed Water Master Plan and included in the 2022 Capital Improvement Plan project list, design in 2022 and construction in 2023. The existing lift station is a triplex, buried-can style lift station that was installed in 1995. There have been a few modifications since its installation which has allowed the lift station to continue to operate for 27 years. The existing on-site generator was repurposed and is capable of providing secondary power to the lift station and Water Treatment Plant#3. This generator is outdated and parts to maintain the equipment are not readily available. The current pumps installed are 20 horsepower pumps, Fairbanks and Flygt are the manufacturers. The improvement will include, but are not limited to, the following items: Removing or abandoning the existing wet well Remove existing generator and consideration for installing the new generator inside the building • Designing a new lift station: wet well and valve vault to meet current resiliency standards • Reconfigure existing gravity system, remove vitrified clay pipe (VCP) and cast iron (CI) to be replaced with PVC pipe New generator with diesel storage New pumps, floats, control panels and variable frequency drive (VFDs) This agenda item would approve Kimley-Horn to redesign lift-station 7W with 15 a fee not to exceed $165,300. RECOMMENDATION Staff requests that the City Commission approve the construction services for lift station 7 improvements/redesign and enter into a contract with Kimley- Horn in the amount of$165,300 and for authorization for the City Manager and City Attorney to prepare and execute any and all applicable contract documents consistent with this Agenda item. 16 Kimley>>> Horn August 26, 2022 Public Works Director City of Winter Springs 1126 East State Road 434 Winter Springs, FL 32708 Re: Lift Station 7W Improvements Kimley-Horn and Associates, Inc.
