FROM: Robert Leible, Superintendent of Water Production
DATE: December 8, 2025
SUBJECT:
A Resolution Authorizing a Two-Year Instrumentation Service Agreement with the HACH Company for $200,093.40 for the Water Production Division.
PURPOSE:
To obtain authorization for a two-year Instrumentation Service Agreement with the HACH Company (HACH), of Loveland, CO, for routine and emergency maintenance service for existing HACH continuous monitoring/on-line laboratory water quality testing instrumentation utilized by the Water Production Division (WPD), at a cost of $200,093.40 ($98,085.00 for 2026 and $102,008.40 for 2027).
BACKGROUND:
The WPD utilizes 88 discrete on-line and laboratory instruments for water quality monitoring, process control, and regulatory compliance, all of which are covered under this service agreement. These instruments analyze parameters such as turbidity, pH, chorine residual, ammonia, and fluoride residual, all on a continuous basis.
DISCUSSION:
Under the proposed agreement, which the WPD has maintained with HACH since 2005, HACH provides regularly scheduled preventative maintenance and calibration service to all instruments covered, prioritized repair service and parts, and loaner instrumentation when needed.
The agreement is advantageous, in that the WPD is assured of high-quality, factory authorized maintenance and repair services and is relieved of the cost of carrying its own inventory of all spare parts. Perhaps more importantly, service is prioritized by HACH, which can prevent regulatory excursions when instruments for regulated parameters are involved. Because the parts and meter components are manufactured by HACH, this maintenance agreement is available exclusively though HACH (sole-source).
Due to discussions with the Purchasing Division which began in 2017, the WPD negotiated a two-year agreement with HACH with separate payments to be made at the beginning of each term year. This renewal agreement would be in effect for the period of January 20, 2026, to January 19, 2027, and a second year from January 20, 2027, to January 19, 2028. Both the Purchasing Division and the WPD believe a negotiated two-year agreement is financially beneficial to the city over the duration of the two-year agreement.
The cost of the proposed two-year HACH service agreement is $200,093.40 ($98,085.00 for year 1 and $102,008.40 for year 2). This represents an increase of $38,414.89 from the
2024 - 2025 two-year agreement or 23.8%, which includes a "locked-in" increase of 4% for the second year.
Funds have been requested in the 2026 City Budget in Account No. 510-4058-511-38-01, and funds will be requested in the 2027 budget similarly. A notarized affidavit is provided indicating the sole source status of the services provided.
IMPACT STATEMENT:
None.
RECOMMENDATIONS:
That a resolution authorizing award of a sole-source purchase, via City Code Section 2-335 (a) (3), to the HACH Company in the amount of $200,093.40 ($98,085.00 for 2026 and $102,008.40 for 2027) be approved by the Mayor and City Council.
