The Drinking Water Treatment, Distribution and Wastewater Treatment Operator Certification Online Exams will no longer be given at the Wallace Building on the Capitol Complex in Des Moines, but will be offered at the DMACC Southridge Testing Center (1111 East Army Post Rd, Des Moines IA 50315), starting March 11, 2019.

Exams will still be offered, by appointment, at Field Office 1 in Manchester, Field Office 2 in Mason City, Field Office 3 in Spencer, Field Office 4 in Atlantic and Field Office 6 in Washington. However, if you wish to take your exam at the DMACC Southridge Testing Center, after receiving your exam eligibility letter, call Elizabeth at (515) 725-0463, and she will set you up with DMACC.

The advantages of using the DMACC Southridge Testing Center include:

• Extended hours of availability
• Convenient location availability and parking

Plus, once you indicate you want to use the DMACC testing center, you will be given a four-week window in which you can go take an exam. There will be no specific appointment date or time; you can just walk in with your eligibility letter and valid ID and take the exam. Although there are multiple workstations available, DMACC asks that you call the day before you are thinking about testing to assure an available testing station. You may call (515) 287-8720.
