Fourteen Trine University senior civil engineering students and two faculty members
travelled to Pittsburgh, Pennsylvania, April 6 and 7 for a senior field trip.
The trip, facilitated by William Barry, Ph.D., and Gary Greene Jr., Ph.D., of the
Reiners Department of Civil and Environmental Engineering, included tours of the Emsworth
Lock and Dam, the ALCOSAN wastewater treatment plant and seven bridges near Point
State Park in downtown Pittsburgh.
At the dam, the US Army Corps of Engineers showed the group the mechanism that opens
and closes the lock gates as well as the control rooms used to operate the vertical
lift gates that manage the depth of the Ohio River.
“We were told that we were the first tour group allowed into the Emsworth Lock and
Dam since 9/11,” said Greene. “They invited us back next year.”
“It was my first time visiting a lock and dam, and the tour was very informative,”
said Austin Gurley, from Collinsville, Oklahoma. “Additionally, I liked the lock and
dam because it incorporates so many disciplines of civil engineering.”
“My favorite part of this stop would have to be when we walked on top of the dam,”
said John LaBounty of Avon, Indiana. “Looking down at the river was breathtaking.”
At the ALCOSAN facility, which treats 250 million gallons of wastewater daily, the
group visited the wet well, a 50-foot diameter, 10-story deep pit that collects all
the wastewater from the Pittsburgh area. They saw the plant’s bar screens, grit chamber,
the tank where the organic solids settle and grease floats to the top and both are
removed, and the activated sludge tanks where microorganisms digest the dissolved
organic material and clean the water.
“Students have visited treatment plants using similar technologies in Angola, but
the ALCOSAN facility is on a considerably larger scale,” said Greene.
“I was not lucky enough to go on prior field trips to the Angola treatment plant in
my time at Trine, so this was my first experience witnessing a treatment plant in
person,” said LaBounty. “I knew a lot about what went into treatment plants from Dr.
Rentz's Environmental Engineering course, but it was neat to see everything up close.”
On Saturday morning, students in Greene’s CE 4523 Bridge Engineering class described
seven bridges along the Monongahela and Allegany Rivers to the other students. Greene
said the bridges featured spans between 400 and 700 feet and were built from the 1920s
to the 1980s.
“You never realize just how much time and effort goes into designing something like
that until you investigate the process. I never thought much about the bridges I drove
over or under,” said LaBounty. “Now, I look at details I never knew about prior to
