A.3 GENERAL SUMMARY OF PROCUREMENT NEEDS

The City of Thornton, CO (“Thornton”) is seeking proposals from qualified radio-frequency (RF)

engineering firms for the inspection, testing, optimization, and upgrade of radios that are part of

Thornton’s water infrastructure supervisory control and data acquisition (SCADA) system. While

Thornton is not presently experiencing any significant performance issues with the operation of

the existing radios, Thornton desires radio replacements and upgrades due to the age of the

existing radios and a desire to standardize the radio models in use. The desired outcome is to

improve the reliability, functionality, and monitoring capabilities of Thornton’s water infrastructure,

ensuring greater operational efficiency and system resilience.

SCADA Radio Service Upgrades

CURRENT STATE, SCOPE OF WORK, AND SPECIAL CONSIDERATIONS

B.1 CURRENT STATE

Thornton is a home-rule city in Adams County, Colorado, located ten (10) miles northeast of

Denver. The City owns and operates a water system serving approximately one hundred sixty-

five thousand (165,000) individuals across thirty-nine (39) square miles, including City residents

and some unincorporated parts of Adams County. Thornton also makes bulk-treated water

deliveries to the City of Westminster. As of 2022, there were over forty-three thousand (43,000)

metered connections to Thornton’s treated water system.

Thornton operates two (2) water treatment plants: the Thornton Water Treatment Plant (TWTP),

located at 920 Thornton Pkwy, Thornton, CO 80229, and the Wes Brown Water Treatment Plant

(WBTP), located at 3651 E 86th Ave, Thornton, CO 80229. These plants have a combined

capacity of 75 million gallons per day and produce approximately 8 billion gallons annually.

The construction and installation of Thornton’s current SCADA infrastructure started in 2011 and

was completed in 2013. Thornton’s SCADA system is currently connected to over seventy (70)

remote sites, including lift stations, metering, pump stations, storage locations, pressure

reducing valves (PRVs), and transfer locations. These sites include a variety of MDS radios,

Phoenix radios, Modicon Quantum, Momentum, Fiber Optics, Programmable Logic Controllers

(PLCs) and Unity Pro PLCs.

Thornton presently uses three (3) repeater site locations: one (1) at TWTP, one (1) at WBTP,

and one (1) located at an elevated tank at approximately W 102nd Ave and Ura Ln, Thornton,

CO 80260 (39°52'54.6"N 105°00'38.1"W).

Each water treatment plant has two (2) redundant iFix servers, an iHistorian server, a Terminal

Services server, a Network Attached Storage (NAS) server, and a redundant Master

Communications PLC. Thornton uses up to forty (40) iClients (iFixT) at three (3) locations:

TWTP, WBTP, and the Infrastructure Maintenance Center (IMC), located at 12450 Washington

St, Thornton, CO 80241.

Thornton is currently undertaking a comprehensive SCADA upgrade project, as well as a project

to automate the TWTP to enable unmanned operations during certain times and periods of the

year. This radio service upgrade project will work in tandem with these on-going efforts to

improve the reliability, functionality, and monitoring capabilities of Thornton’s water infrastructure.

B.2 SCOPE OF WORK – GENERAL

The scope of this project is radio services for sixty-two (62) remote sites and the two (2) water

treatment plants. The project is divided into eleven (11) tasks, which will be completed in four (4)

phases – Design, Recommendation, Implementation, and Sustainment – as described further

below.
