1 <br />City of Mounds View Staff Report <br />Item No: 8B <br />Meeting Date: February 26, 2024 <br />Type of Business: CB <br />Administrator Review: <br />To: Honorable Mayor and City Council <br />From: Don Peterson, Director of Public Works/Parks and Recreation <br />Item Title/Subject: Resolution 9879, Approving the Proposal for Installing Electric <br />Output Filters on the VFDs at Water Treatment Plant #2 (Well 5) and <br />Treatment Plant #3 (Well 6) <br />Introduction: <br />The City Council Approved Resolution 9860 authorizing Municipal Builders Incorporated <br />(MBI) to install electric output filters at the Main Water Treatment Plant in order to prevent <br />potential well motor failure caused by electrical surges. <br />Background/Discussion: <br />Variable Frequency Drives (VFD's) electronically control the speed in which the well <br />motor starts. In October of 2023 Well Motor #3 failed, the contractor removed the motor <br />and performed an inspection for the failure. The motor manufacture highly recommended <br />that electric output filters be installed after the VFD and before the well motor, as these <br />filters are designed to catch any electrical surges that could harm the motor. <br />After the installation of the electronic filter at Well #3 the Staff requested the contractor to <br />provide a proposal for installing these filters at Water Treatment Plants #2, Well 5 and <br />Plant #3, Well 6. <br />Further Discussion: <br />MBI submitted a proposal for installing electric output filters on the VFD's at Water <br />Treatment Plant #2 and Plant #3 for a total cost of $14,393.74. <br />Strategic Plan Strategy/Goal: Maintain and Plan for Infrastructure Improvements. <br />Ensure Clean Water and Maintenance. <br />Financial Impact: No financial Impact to the 2024 Budget. The 2024 Water Fund <br />budgeted estimate of $275,000.00 for Water Treatment Plant Engineering, Design and <br />Construction. <br />Recommendation: <br />Staff recommends Council approve the attached resolution accepting the proposal from <br />Municipal Builders Inc. to install electric output filters on the VFDs, at a total cost of <br />$14,393.74 to be funded from the 2024 Water budget account 700-4823-7050. <br />Respectfully submitted, <br />Don Peterson, Director of Public Works/Parks and Recreation <br />The Mounds View Vision <br />A Thriving Desirable Community <br />
