InfoKarl Kohlhoff, P.E. (CE '56) is an internationally recognized leader in the water industry, with extensive expertise as both a utility manager and environmental engineer. He worked for nearly 20 years on water and wastewater issues for the City of Mesa, Ariz. and now is the national director for water at HDR Engineering, Inc. in Phoenix, Ariz.

Under his leadership, the City of Mesa instituted what has become one of the premier water conservation programs in the nation. Mesa reduced its per capita water use from 212 gallons per person per day in 1980 to 190 gallons in 2000.

These gains are impressive because the city grew from a bedroom community to a balanced city, with strong commercial and industrial sectors, during those same years. Also, the 212-gallon starting point was well below the 260 gallons being used in Phoenix and other nearby towns in 1980.

During that time, the city also instituted several measures that reduced the amount of water unaccounted for from 11 to 4 percent. This resulted in several billion dollars of additional revenues for the city.

Kohlhoff retired at age 67 from the City of Mesa in 2000, but went to work for HDR Engineering in January 2001. Instead of retiring to the golf course, he wanted to share his expertise on water issues.

"I believe strongly in service, in giving back to the community," he says.

Kohlhoff's career has included many such efforts to "give back," including service as:

• Vice president, president and past president of the 450,000-member American Water Works Assoc.

• A member of the Gilbert Planning and Zoning Commission. He's currently in his third term with the commission.

• President of the Arizona Water & Pollution Control Assoc.

• A junior college faculty member teaching water and wastewater utility operation for 18 years.

• A reserve officer with the Army Corps of Engineers for 30 years, retiring as a colonel in 1986.

• Operator of a surface water system that serves 35 customers near his second home in Arizona's Mogollon Rim country.

• A member of the Gilbert School Board.

• The governor of the Kiwanis International's Southwest District.
