Title
Resolution to Award Purchase Order to Hach Company for Purchase of Water Quality Monitoring Instrument Panels ($54,818.20)
Memorandum
This memorandum and resolution requests approval to award a purchase order to Hach Company for the purchase of two water quality monitoring instrument panels. This project originated as a recommendation from Vulnerability Assessment for the water system that was mandated by the Bioterrorism Act of 2002 post 9/11. This project entails adding water quality monitoring devices at strategic locations throughout the water distribution system to monitor water quality and help identify potential distribution system water quality events. The water quality monitoring component will allow the Water Treatment plant the ability to detect variations in water quality that might indicate an imminent problem, and provide Water Utility staff time to address the problem before impacting customers. While a number of locations were identified for placement of water quality monitoring devices, this project will pilot two of those locations. Upon installation of the water quality monitors and evaluation of the data from those monitors, the City will determine if this pilot system should be expanded to the remaining locations.
In 2007 the City completed a Distribution System Water Quality Monitoring Study that included recommendations for locating water quality monitors throughout the distribution system as well as recommendations for the types of monitors to be used. The site location evaluation was completed in partnership with the United States Environmental Protection Agency (USEPA) through their Threat Ensemble Vulnerability Assessment (TEVA) program. In addition, the Water Treatment Plant piloted several monitors from several manufacturers as part of this study. This study recommended using the Water Quality Monitoring Panel manufactured by the Hach Company, as it was the only panel that included all of the recommended devices.
