Water/Wastewater Operator Mathematics

This course utilizes a step-by-step systematic approach to mathematical problem solving required to pass the Water/Wastewater Operators Level 3 and 4 exams.  By successfully completing all phases of this course, operators will develop the capability to solve mathematical problems typically encountered by Level 3 and Level 4 Operators.  Developing this skill set is not only highly useful to operators for passing Operator Certification Exams but is also a reliable source for accurate water and wastewater calculations required by water operators’ positions.

Key Aspects of the Course include:

  • Review and Practice of Basic Math Terms, Rules and Techniques
  • Learn a step-by-step method for solving basic conversion problems
  • Establish a high degree of familiarity with basic geometric calculations, flows, detention times and dosage calculations as well as other operations related calculations
  • Development of a Systematic (Step by Step) method for confidently and reliably solving mathematical word problems, along with the ability to verify the correctness of answers


Successful completion of this course will also provide students with class credit through NM State Drinking Water Bureau as well as developing strong set of basic skills useful in solving day to day math problems outside of the workplace and will provide a solid foundation for further mathematical studies.
