O BRUMN the city that works for you Report Number Agenda Section Council Meeting Date REQUEST FOR COUNCIL CONSIDERATION 14 -231 VI -5 September 9, 2014 ITEM DESCRIPTION: CONSIDERATION OF QUOTES FOR CITY PROJECT 13 -15, LIFT STATION 7 GENERATOR DEPARTMENT HEAD'S APPROVAL: k-YIW CITY MANAGER'S APPROVAL: No comments to supplement this report Comments attached Recommendation: Accept the quotation from Cummings in the amount of $16,800 for a 40kW generator to be installed at Lift Station 7 and approve the total estimated project of $36,800. Legislative History: On June 10, 2014, the City Council authorized the Public Works Director to solicit quotes to purchase a Permanent Standby Power Generator for Lift Station 7, and work with a Professional Land Surveyor and the City Attorney to negotiate a 20 -foot x 40 -foot sewer easement for placement of the generator, SCADA equipment, and future anticipated Lift Station 7 improvements. This is in response to lift station power outages and sewer back -ups experienced in 2013 and documented in a report finalized in January of 2014 by Foth Infrastructure & Environment, LLC. Financial Impact: The following quotations were received for the purchase of a 40kW generator to be installed at Lift Station 7 located behind the house at 636 Cleveland Ave SW: Total Cummings $16,800 Ziegler Inc. $24,080 Explanation: Lift Station 7 provides service to a significant area of the City. The lift station structure has a small wet well and very limited storage capacity so it cannot be out of service for extended periods of time without risk of wastewater backing up into nearby basements. As a result, this lift station must have power available to it at all times. The lift station site is located in a very small area with limited access, bordering an existing multi - family garage complex. This restricted area complicates the delivery and set up of any portable generator equipment. When the lift station experiences power outages, electrical power is provided by a portable generator that is delivered to the site and manually connected as necessary. The station is located at the end of a narrow driveway between a garage structure and a chain link fence and access is available across an apartment complex parking lot. In consideration of the relatively difficult access and the limited emergency storage, a permanent standby generator with an automatic transfer switch is proposed to be installed at this site to automatically provide power during outages. Staff included the following as part of a permanent generator system: • Install a new transfer switch. • Install a new 40KW, 240V single phase natural gas generator. • Wire and conduit from the existing disconnect to the new transfer switch. • Wire and conduit from the generator to the transfer switch. • Wire and conduit from the transfer switch to the existing control panel. • Concrete pad to set the generator on. • Tree removal and grading west of the lift station for the generator site. The existing easement area for Lift Station 7 manholes and controls is not large enough to accommodate the stand -by generator and future planned lift station improvements.
