A UT Arlington environmental
engineer has been awarded a $394,300 grant from the Tarrant Regional Water
District to ensure water quality and flow in the new facilities of the 150-mile
Integrated Pipeline Project.
Andrew Kruzic, UT Arlington
associate professor of civil engineering,
will investigate the best methods and locations to add monochloramine to the
water in an effort to eliminate biological growths in the new pump stations and
pipelines. Adding monochloramine is widely practiced throughout the United
Biological growth decreases the
flow rate in the pipelines and increase the cost to deliver the water.
The monochloramines will be removing
biofilm and invasive species, such as the zebra mussels, that have infested
some North Texas lakes. Kruzic also will study how to inhibit internal
corrosion, and recommend locations along the pipeline for water treatment.
“As North Texas builds the $2.3
billion, 150-mile pipeline from Lake Palestine in East Texas to Tarrant County,
the builders have to ensure what they’re getting will be as efficient and last
as long as possible,” Kruzic said. “We want to make sure the pipeline is flowing
as much water as possible to North Texas.”
The first portion of the pipeline
is scheduled to be operational by 2021 and will deliver up to 350 million
gallons of raw water per day to North Texas. The Tarrant Regional Water
District and Dallas Water Utilities are teaming together for the project. TRWD
has 70 customer cities. DWU has 27 customer cities. Together, the two providers
supply water to more than 4.4 million people in 13 North Texas counties.
“Dr. Kruzic’s research is necessary to help us operate the pipeline
efficiently, while also meeting the targeted project-life of 100 years,” said David
Marshall, engineering services director for the Tarrant Regional Water District.
“The Integrated Pipeline Project is critical to ensuring water supplies to support
long term growth in North Texas.”
Currently, water utilities rely
on monochloramine, a combination of chloride and ammonia, to disinfect and
protect water supplies from disease-causing microorganisms, Kruzic said.
Kruzic is teaming with Kevin Schug, a UT Arlington associate professor of
chemistry and biochemistry, in the research. Schug also is the Shimadzu
Distinguished Professor of Analytical Chemistry. His work is based in the Shimadzu
Center for Advanced Analytical Chemistry at UT Arlington. The research will
rely on one of Shimadzu’s chemical analysis machines.
Kruzic also said that he will serve as a consultant to the Tarrant
Regional Water District to choose instrumentation for chemical and
environmental monitoring on the pipeline. Finally, part of the grant calls for
Kruzic to help incorporate the research results into final design for the
Khosrow Behbehani, dean of the UT Arlington College of Engineering, said
Dr. Kruzic’s work is vital to ensure continued growth in North Texas.
“This pipeline can get needed water resources to North Texas,” Behbehani
said. “Dr. Kruzic’s research will have long-lasting impact on providing safe water
for current and future North Texas residents and businesses. His methods and
procedures certainly could be used by future projects involving large volumes
The University of
Texas at Arlington is a comprehensive research institution of more than 33,800
students and 2,200 faculty members in the heart of North Texas and the second
largest member of The University of Texas System. Research activity has more
than tripled over the past decade to $71.4 million last year with an emphasis
on bioengineering, medical diagnostics, micro manufacturing, advanced robotics
and defense and Homeland Security technologies, among other areas. Visit www.uta.edu to learn more.
