forcemain project to 2024 and adding the proposed rehabilitation work at Lift Station 7 and Lift Station 13 for 2023. The Lift Station 7 rehab project has two elements, wet well work and bypassing sewage for approx. 3 days (including overnights). The total combined cost for contracted services, labor, and parts - $89,506. Lift Station 7 Scope - • Contract replacement of 2 complete submersible sewage pumps, 2 base elbows, guide rails, and misc. brackets within the wet well. • Utilize Northern Dewatering to setup and take down a bypass pumping system. The pumping will need to be monitored by an AHPW staff member 24 hours a day. At this point, no special permitting is required for this project. • AHPW is responsible for the initial wet well cleaning, plugging the main lines, ramping the bypass along County Road D, and providing traffic control. • EP will provide a full equipment startup inspection and staff training on the new components. Proposals for the bypass pumping were received from two companies that were capable of providing the service and equipment needed. The total cost difference between the two proposals was $2,157. It is the recommendation of City Staff to contract with Northern Dewatering, even though they have the higher proposal. They have specialized experience and have shown an engineered bypassing design that staff has reviewed and is confident in using for this project. The Lift Station 13 rehab project has two elements, wet well work and bypassing sewage for approx. 2 days (16 daytime hours budgeted). The total combined cost for contracted services, labor, and parts - $81,984 Lift Station 13 Scope - • Contract replacement of 2 complete submersible sewage pumps, 2 base elbows, ductile piping, and misc. brackets within the wet well. • Utilize Olson's Sewer to bypass truck sewage during daytime hours. The bypass trucking will need to be monitored by an AHPW staff member. At this point, no special permitting is required for this project. • AHPW is responsible for the initial wet well cleaning, plugging the main lines and providing traffic control. • EP will provide a full equipment startup inspection and staff training on the new components. If approved, this project is anticipated to be completed September 2023. Budget Impact This project will be covered by the sanitary sewer fund. In addition to the contracted costs of $171,490, the City will also incur overtime costs due to the monitoring needed by an AHPW staff member. The impact to the Sewer Fund of moving these two lift stations up 7+ years will not be known until we are further along in the 2024-2028 CIP process. Page 2 of 3
