Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a contract with Arcadis U.S., Inc. for professional services and construction services for the SWWTP VFD & Harmonic Filter Upgrades project, CIP #650346-100002, in an amount up to $443,624.94.

The Department of Public Utilities’ (DPU) Division of Sewerage & Drainage (DOSD) has identified numerous Variable Frequency Drives (VFDs) and Harmonic Filters at several Southerly Wastewater Treatment Plant (SWWTP) processes that are nearing the end of their useful service life and are becoming increasingly difficult to repair and maintain. These processes include the fine screens, the Return Activated Sludge (RAS) pumps, the thickening centrifuges, and the skimmings’ concentrators. This project will provide specialized professional engineering services to evaluate, replace, configure, and program the VFDs and harmonic filters, provide new controls that may be necessary to integrate the new equipment into the existing systems, and provide any other ancillary work to provide a fully functioning system. This work will also include recommendations for the standardization of equipment that can be used in the DOSD Guide Specifications and programming of Programmable Logic Controllers (PLCs). The equipment specified will vary based on site conditions, building use, building permit requirements, and ease of maintenance issues. Consideration shall be given to increasing ease of maintenance, development of standardized operating systems, and specifying control systems access software. This work is part of the City’s continuing effort to upgrade its treatment facilities, provide efficient, reliable, cost-effective operations, and enhance personnel safety.
