Wastewater Department
Hach Brand Monitoring Equipment Purchase
To approve the purchase of monitoring instrumentation for the Wet Weather
Facility from Hach Company of Loveland, CO in the amount of $25,631.95.
Funding will be through: Department: 169 Wastewater; Fund: WERF; Account
Category: 71 Equipment.
Hach Quote
Operators use pH and Total Suspended Solids as measurements to determine the
quality of treatment as well as make adjustments to the chemical treatment
process. These instruments have a lifespan and are currently approaching the end
of their useful life. It is prudent to replace these instruments prior to them ceasing
to function, which will result in a decrease in the quality of treatment. The
Wastewater Facility respectfully requests to replace the Wet Weather Raw Water
Turbidmeter (WW-RWT), the Wet Weather Settled Water Turbidmeter (WW-
SWT), the pH meters (WW-pHM), as well as the associated controlling modules.
These are direct replacement with Hach as the sole source and are FY18
scheduled replacements within the Wastewater Equipment Replacement Fund
(WERF).
