AGENDA INFORMATION SHEET
DEPARTMENT: Procurement
ACM: Christine Taylor
DATE: April 21, 2026
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Trihedral Inc., for an HMI Software System for the
Water Utilities Department; providing for the expenditure of funds therefor; and providing an effective date
(RFP 8741 – awarded to Trihedral Inc., for five (5) years, with the option for five (5) additional one (1)
year extensions, in the total ten (10) year not-to-exceed amount of $886,000.00). The Public Utilities Board
recommends approval (4 - 0).
STRATEGIC ALIGNMENT
This action supports Key Focus Area: Enhance Infrastructure and Mobility.
INFORMATION/BACKGROUND
Operations staff at both the Water Production and Water Reclamation plants utilize Human-Machine
Interface (HMI) software to control water treatment flows from start to finish through Supervisory Control
and Data Acquisition (SCADA) systems. This software enables control of all field equipment, including
pumps, motors, valve actuators, and instrumentation, while providing positional feedback for each piece of
equipment from a central location. This helps the operations staff understand the current state of water
quality and, if necessary, make changes through the software.
Currently, the Water Production and Reclamation plants operate on different software platforms, which are
also outdated. This new HMI/SCADA project will not only update the software used but also consolidate
all treatment plants onto a single software platform, which will enhance technical support and minimize
potential downtime.
