9.j Quotes for pump replacement at Bliss Lift Station Staff Report Date of Meeting: December 19th, 2017 To: Mayor, City council From: Adam Hawkinson, Director of Public Works Re: Bliss Lift station #1 Pumps and Component Upgrades Background: The 201 Bliss systems were installed in 1986 using a federal grant obtained through Washington County. The responsibilities as owner of the system were turned over to the City of Scandia in 1988. The County was contracted to maintain the system until 2012 at which point the City staff began to maintain the system. There are no records in the public works files regarding maintenance of claws, elbows, or check valves in the system. In accordance with the grant; “the owner (City) shall be responsible for the operation, maintenance, and replacement of all publically owned components of the community sewage treatment system.” For the 201 Bliss lift station #1, there are no funds in the CIP budget for 2018 through 2022. At the 201 Bliss lift station #1 there were regular alarms at the end of Novemb er. Pump issues and pipe outlet connections to those pumps were identified as the cause. Pump one was replaced to keep the system operating without alarming due to high levels. Since then pump #2 has failed. There is now one working pump motor in the lift station. The claw fittings and base elbows are worn so that proper connections cannot be made to seal the outlet manifold and pump together for effective pumping. The sin gle pump is now running 12 to 15 hours per day. Another issue is the check valves are working intermittently which causes discharge to re-enter the tank through the other pump that is not operating. Also, the replacement pumps that have been installed in the past have their wiring spliced inside the tanks which is continuously exposed to moisture and may lead to early pump failure if not sealed properly. Issue: Should the City invest in installing new equipment and parts to fix those failing in the 201 Bliss lift station #1 or take other actions? Proposal Details: On the following pages I have provided three bids for the council to consider. My proposal is that both pumps are replaced at this time with new claws, check valves, elbows, and wire the pumps directly into the control panel so that the station will operate efficiently. Spec. sheets are on additional attachments. Fiscal Impact: In the 2018 budget there is $13,000 in funds between the miscellaneous contractual, and maintenance/repair line items for this repair. Later in 2018 there may be a request for additional funding due to this immediate need. Options: 1.

Per our conversation this pump should develop the flow and head you need as it has almost the 2 times the shutoff head as the SPD50 does. I’ve attached the pump curve and technical data / cut sheets for your review. This pump is about the same as the Barmesa pump hydraulically except the Myers pump will have two mechanical seals protecting the motor and a 2 year warranty. 2- FE Myers model P52D ½ HP 230volt motors, 30’ cords. 2- Conery 2” Base elbows with integral check valve and lifts out with the pump “claw” for service. 2- Stainless Steel upper guide rail brackets.(reuse existing guide pipe) 1-Lot 2” Schedule 80 discharge pipe and fittings, stainless steel anchor bolts. 1-Labor to install base elbows, pumps, pull float and old pump cords out of the *conduit. Your cost for above equipment installed………………$5,502.00 *We don’t know the condition of the conduit or how the pump and float cords are sealed in the conduit. These could be glued in place with CHICO (which is a liquid putty poured into the conduit to seal the conduit from lift station gases. It gets hard as a rock when it cures.) Pulling the cords out of the old conduit could damage the float cords. If this is the case we can cut out the piece of conduit that holds the CHICO and install a new piece of conduit and leave a gap in it act as an air gap to vent wet well gases. We’ll bring replacement floats to the job. These will be replaced at $56.00 each as needed. Thank you, Steven P.
