How do operators and technicians overcome flooding, a sewer collapse, process failure and other emergencies?

Do you ever wonder what transpires behind the scenes during the operation of a water resource recovery facility? Instead of continuing to take these unsung specialists for granted, learn how the best wastewater collection and treatment personnel in the world display their skills at Operations Challenge.

In the competition, teams compete to earn the highest score in five different events. Each team includes four members and often a coach as well. Each event is designed to test the diverse skills required for the operation and maintenance of water resource recovery facilities, collection systems, and laboratories. The five events are collections systems, laboratory, process control, maintenance and safety. Winners are determined by a weighted points system.

Operations Challenge, the water sector's premier skills competition, is unmatched in delivering cross training, team building, and professional development.

Thanks and Congratulations to all 55 teams who competed in Operations Challenge 2023.

There are three Divisions at Operations Challenge at WEFTEC. 

Division I
Returning teams* that were in the top nine overall winning positions in Division 1 the previous year. This also includes any returning team that competed in the previous year's Division II Competition and placed in the top three positions overall.

Division II
Returning teams who do not qualify for Division I. This also includes any returning team that competed in the previous year's Division III Competition and placed in the top three positions overall.

Division III
New teams whose members have never competed at WEFTEC for that utility. A team may compete in Division III for up to two consecutive years. If a member has previously competed at WEFTEC, but not for their current employer, their team is eligible to compete in Division 3. 

*A returning team is defined as any team that includes at least three members of the team that have participated in any of the previous two WEF Operations Challenge competitions from that member association.
