AGENDA INFORMATION SHEET
DEPARTMENT: Procurement & Compliance
CFO: Antonio Puente, Jr.
DATE: February 4, 2020
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 HACH Company, for the purchase of various items
for the municipal laboratory, water production, water reclamation, and wastewater collection departments,
which is the sole provider of these products, in accordance with Texas Local Government Code 252.022,
which provides that procurement of commodities and services that are available from one source are exempt
from competitive bidding, and if over $50,000 shall be awarded by the governing body; and providing an
effective date (File 6898 - awarded to HACH Company for one (1) year, with the option for two (2)
additional one (1) year extensions, in the total three (3) year not-to-exceed amount of $300,000). The Public
Utilities Board recommends approval (7 - 0).
INFORMATION/BACKGROUND
The water and wastewater departments use various HACH Company products in their daily operations for
testing, monitoring and real-time control of their plants' operations as well as flow measurement in the
wastewater collection system. These products from HACH are fully integrated into the daily water and
wastewater operations, and only available from HACH. Hach is the sole source provider of its equipment
and replacement parts. Due to the complex technical nature of water quality monitoring both at the water
treatment plant and in the water distribution system, as well as the strict regulatory reporting requirements,
replacement parts and reagents from alternate vendors would not be compatible. Additionally, calibration
and repair services are specific to the instrumentation as well. The City of Denton water treatment plants
rely on Hach turbidity, chlorine, pH, phosphorus, dissolved oxygen, ammonia and many other monitoring
parameters to supply and maintain their equipment for their regulatory requirements.
For Water Production to replace all of their existing Hach equipment, it would cost approximately $400,000
plus the added costs of programming, and training plant personnel on new equipment.
In addition, the Phosphorus measuring on-line instrumentation made by HACH used in Pecan Creek Water
Reclamation Plant is integrated into the fiber network of the SCADA. The output from the HACH
equipment controls the chemical dosages required for the plant to meet its TCEQ permit. In 2015, when
this equipment was purchased, it cost the City of Denton approximately $145,000. To replace it with another
brand would costs at least this much plus it will require extra costs for reprogramming the PLC to match
the logic controller for another brand. For Water Reclamation and Collections to replace all of their existing
Hach equipment, it would cost approximately $350,000-400,000, plus the added costs of programming, and
training plant and collection system personnel on new equipment.
