Two million gallons of water. Five bodies of water. More than 200 former and current Olympians.
Intimidating numbers -- unless you are the operations manager at the IU Natatorium. For 20 years, Keith Dollard has expertly maintained the swimming pools, hot tub, cold plunge tub (kept at 55 degrees) and diving well within the hallowed athletic complex at IUPUI.
"You see a lot of former Olympians, and possibly future Olympians, competing in these meets," Dollard said. "I have to make sure all of the water systems are running properly."
From community swimming lessons to international diving events, Dollard and the Natatorium team work hard to provide the venue with the best, safest conditions for the athletes. But most people in the stands -- and even most of the competitors -- don't know the advanced machinations that reside below the pools.

[Dollard speaks in voiceover as the camera pans various aspects of the systems: ... a pretty well-known Neptune-Benson system, and we have a BECS Control chemical system.

Three filtration systems, each about the size of a studio apartment, churn the water through more than a football field's length of pipes. Lint, hair and skin collect into long vertical filters within the systems' tanks. Among the many readings on LED screens are the status of the filters, which must be monitored and "bumped" several times a day: A large metal plate bumps into the filters automatically, knocking loose the debris to be collected at the bottom of the tanks and disposed of.
The mechanical room -- also known as the "belly of the beast" -- monitors chlorine levels, water flow rates and pool temperatures.
"We have to follow state codes for pH levels and chlorine residual," Dollard explained. "Right now, our competition pool is floating around a 7.3 pH. Usually, you want to keep your pool between a 7.2 and a 7.6 per code and swimmer comfort."
The pool temperatures are kept regulated for swimmers: The competition pool is at 79 degrees, and the diving well is at 84 degrees. The smaller practice pool, which also hosts swimming lessons for the public, is kept at a balmy 84 degrees as well.
Dollard and the Natatorium staff must keep close watch on the water topside, too. Much like the staff at your public pool, Dollard retrieves water samples regularly to monitor chemical balances utilizing a liquid agent test kit. The chemicals give different readings from the water samples scooped up from the pools.
In each small sample, Dollard and the Natatorium lifeguards look for a few different readings. For pH levels, five drops of a phenol red reagent are added to the water. After a shake of the sample, the water turns to a shade of orange. If the sample is red, the pH is too high. For a chlorine test, two reagents -- a clear R1 and a light-sensitive R2 -- get added to the sample. The desired color on the testing kit is a light purple. A dark purple indicates too much chlorine.
For most events, Dollard collaborates with Campus Facility Services skilled trades and outside contractors. Depending on the size and level of the meet, extra lighting, scoreboards and video screens for spectators will be installed. Dollard is also involved with the various graphics and banners hung for each event.
"From a high school or college meet to a USA Swimming meet, the only difference is the high-profile athletes," Dollard said. "We always try to put on a big show, from the little kids clear up to the Olympians."
