21gKj Report Number 14 -148 Agenda Section VI -10 BRI(ATfUN the city that works for you Council Meeting Date June 10, 2014 REQUEST FOR COUNCIL CONSIDERATION ITEM DESCRIPTION: CONSIDERATION OF AUTHORIZING STAFF TO SOLICIT QUOTES FOR CITY PROJECT 13 -15, LIFT STATION 7 GENERATOR DEPARTMENT HEAD'S APPROVAL: Q)mv) CITY MANAGER'S APPROVAL: No comments to supplement this riot omments attached Recommendation: To authorize the Publ' W s Director to perform the following actions: 1. Solicit quotes to purchase a Perma nt Standby Power Generator for Lift Station7. 2. To 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. Legislative History: The City hired Foth Infrastructure & Environment, LLC to analyze Lift Stations #2 and #7, and this report was finalized in January of 2014. Financial Impact: This project, if approved, would be funded from Sewer Improvement Fund 402 Explanation: Lift Station 7 provides service to a significant area of the City. It 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 backing up wastewater into nearby basements. As a result, this 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. Lift Station 7 has limited emergency storage capacity and standby electrical power is currently 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 should 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 diesel 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 to set the generator southwest of the lift station. 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. Kemper and Associates will complete a boundary survey and create the required easement documents to allow the City to negotiate an agreement for the adjusted easement corridor. Costs and Funding: In the 2014 Utility Rate Analysis the anticipated costs for the generator were estimated to be $37,000. This did not include any easement acquisition costs. The negotiated easement will be approved as part of a future City Council Action. Grant Wyffe , P.I ?.. Director of Public Works Attachments: Lift Station 7 Survey
