Call for conference topics

Please help us develop sessions for MPCA's upcoming Wastewater Conference in November.

Our annual conference benefits wastewater operators statewide. We'd like your ideas, from hot and trending to traditional.

In Minnesota, wastewater treatment operators — those responsible for the daily, onsite operation of wastewater facilities and collection systems — must be certified. Their class of certification must be equal or higher to the class of the facility. The MPCA administers the certification program and provides workshops and conferences to help you stay up to date on your certification.

Treatment facilities are classified A, B, C, and D according to a rated point system based on the unit processes, loading to the plant, and the permit's final effluent limitations

Type S systems — collection, pumping, and conveyance facilities distinctly separate in operation from treatment facilities — are classified S-A, S-B, S-C, and S-D based on the community's population. Where a type S facility is not distinctly separate, it is considered part of the treatment facility.

  • Class S-A: serving a population of 50,000 or more
  • Class S-B: serving a population of 15,000 to 49,999
  • Class S-C: serving a population of 1,500 to 14,999
  • Class S-D: serving a population of less than 1,500

Note: A city manager, superintendent of public works, or other administrator is not considered an operator unless their duties include the day-to-day operation of a wastewater facility.

Course descriptions

The MPCA wastewater courses require basic math skills.  While math concepts are reviewed in the courses, this is not a substitute for having a GED-level math understanding. 

Attendees needing to refresh basic math skills can find help online with tutorials (free and for hire), as well as in-person tutoring options that can be found with an Internet search to meet individual wants and needs.

Course attendees are responsible for bringing and knowing how to use their own scientific calculator capable of performing basic (addition, subtraction, multiplication, and division) and complex (square root, exponent) operations. This is required equipment for most MPCA training events and for all wastewater exams.

Programmable (graphing) calculators and phones (smartphones) are not allowed during an exam. The MPCA does not have calculators to borrow or loan to attendees. Scientific calculators can be purchased at a wide variety of retailers (locally and online) for under $15. Please plan to bring your own calculator to MPCA wastewater courses.

Instructors will provide additional math help/assistance at the end of the first two days for all 16-hour training events. These additional help sessions are provided for attendees who want or need extra opportunities to practice solving common math-related problems.

Collection system basic seminar

Intended for entry-level operators or as a refresher for experienced operators. Covers proper operation and maintenance of wastewater collection systems. Topics include inflow/infiltration, lift stations, collection system cleaning, traffic control, safety, collection system math, and more. Exams offered on the last day. Contact hours: 16 Wastewater.

Exam refresher sessions (A/B and SA/SB, C/D and SC/SD) 

Exam refreshers are offered to help wastewater operators refresh their basic knowledge about need-to-know content required by law. Please acknowledge a 16-hour refresher seminar cannot replace months or years of experience-based learning and/or independent study of wastewater industry need-to-know qualifications.

Exam refreshers will also provide opportunities to practice solving common math-related problems such as pump calibration, geometric mean, discharge math, converting units, using common formulas, calculating loading, calculating food-to-mass ratio, and calculating volume, area, velocity, and perimeter. Exam refresher instructors will focus on need-to-know content when offering examples and demonstrations during exam refresher sessions.

Exam refresher sessions are not offered to rehearse or memorize how to answer wastewater exam questions and they do not provide attendees with correct answers for specific exam questions.  

You must pre-register to attend exam refresher sessions. Attendees enrolled in an exam refresher session must bring a pencil and a nonprogrammable calculator. Smartphones and programmable calculators are not allowed during the exam. Contact hours: 12 Wastewater.

In-person seminars may also include a field trip to a stabilization pond. This course is intended for entry-level operators or as a refresher for experienced operators. Exam offered on the last day. Contact hours: 16 Wastewater.

Type IV (land application) basic course

This course is required for those who want to become certified as Type IV operator or inspector.

Type IV (land application) refresher course

The Type IV Biosolids land application training is recommended for operators and inspectors who need to renew their Type IV certificate or who need a refresher. The seminar reviews land-application management procedures, including elements of the basic course. The Type IV (IBP break-out session) is recommended for Type IV operators that land apply industrial wastes, including food processing, wood ash, industrial wastewater sludge, pretreatment sludge and more. Topics include site suitability, application rates, permitting requirements and waste management. No Exam. Contact Hours: 6 Type IV or 6 Wastewater.

Type V (spray irrigation) basic seminar

Training recommended for entry-level spray irrigation operators or as a review for experienced spray operators.

Wastewater training accreditation

If your organization offers wastewater operations training and would like to be accredited to offer training to Minnesota operators, you must apply to the MPCA. To receive training program approval prior to the course, submit the form to the MPCA at least 60 days before the training event.

Certification exams

Certification exams are offered at MPCA training seminars on the last day of class. Eligibility is determined by experience and/or education requirements. Exam applications must be received 15 days prior to the exam along with the exam fee, a description of your job duties, your length of service, name, and supervisor's phone number. If you are substituting educational experience for operating experience, submit a copy of a college diploma or other proof of school attendance or graduation.

All exams are closed book. You will be given a formula book. Bring a non-programmable calculator (no smartphones) and a No. 2 pencil. A passing grade is 70 out of 100. If you fail the exam, you can retake it after three months. We can identify the topics of incorrect answers, upon request, to help you focus your areas of study. You can review your exam if you submit a request within 60 days of notification of the results.

The agency will notify you if you pass the exam. Then you must submit the $45 certification fee within 90 days to become certified. If you don't submit the fee within 90 days, you must apply for re-examination.

Certificates expire three years after being issued. During that time the following contact training hours must be met for renewal:

  • Class A and S-A = 32 hours
  • Class B and S-B = 24 hours
  • Class C and S-C = 16 hours
  • Class D and S-D = 8 hours
  • Type IV = 6 hours
  • Type V = 6 hours

Need to know

Need to know criteria can help wastewater and collection system operators understand the basic skills necessary to operate a system or run a plant.
