Math Handbook for Water System Operators: Math Fundamentals and Problem Solving
Water system operators use mathematics to make key operational decisions. Math is also used in planning system maintenance, laboratory analyses, keeping records and estimating budgets. It is important for the operator to have an understanding of math fundamentals along with the technical concepts of water system operations.
By reviewing the math principles presented in this text and linking these principles to water system concepts, the operator can better understand and solve math related problems. This Handbook presents common water system problems and the methods used to solve these problems.
Math Handbook for Water System Operators is a valuable resource in preparing the operator for math problems given on licensing examinations for water treatment and water distribution operation. Typical exam problems are solved in an easy to understand, step-by-step format.
