Develop your skills in applying basic arithmetic concepts, techniques and methods to everyday problems associated with water and wastewater system operations. Water Operators will learn techniques and methods that will ensure adequate quantity, pressure and quality of drinking water that will protect public health. Wastewater Operators will learn how to solve common problems to ensure compliance with state rules to ensure protection of the environment.

This course presents approved training for Asbestos Cement Pipe Work Practice Procedures in compliance with the most recent Department of Labor and Industries regulations. Participants will learn safe, field-proven procedures to protect them from cancer-causing asbestos fibers and how to avoid costly penalties. Discover how to recognize asbestos health hazards, prevent exposure to deadly asbestos fibers and how to choose and use protective equipment. Participants will also perform approved AC pipe work practices.

In this five-day course, participants will learn how to: identify types of backflow preventers, components, and functions; inspect backflow prevention assembly installations; test and diagnose simulated problems in all types of approved backflow prevention assemblies; record and report assembly test results. Emphasis is placed on preparing for the Backflow Assembly Testing Exam, but the exam is not included in this class (see explanation below).  This class combines classroom instruction with ample hands-on practice in WETRC's BAT Lab.

This three-day course provides Backflow Assembly Testers with the information they need to meet the Professional Growth Examination requirement for Backflow Assembly Tester Certification, Professional Growth Requirement in Washington State. Participants will refresh their knowledge of backflow preventers, the backflow preventer components, and how they function. Learn the latest specifications for backflow prevention assembly installation and inspection. This is a hands-on workshop where students will practice approved procedures to test and diagnose simulated problems in different kinds of assemblies as you prepare for the BAT Professional Growth Examination.

This class is designed for BATs who want to get their Specialty Plumbers License through Washington Department of Labor and Industries. Course will focus on how to effectively prepare for the exam.

State and Federal regulations require a Competent Person to be present on every job site where the earth is opened and a person enters to do work. This includes sewer and water line installation and repair, utility work, road and other construction.

This course is an introduction to sample collection for potable and non-potable water sources. While this course focuses on Bacteriological Sample Collection, students will also receive training to prepare them for collecting other types of required samples used in evaluating water quality.

This course prepares water and wastewater employees to apply proper techniques using acceptable methods to collect various types of water samples.

Water and wastewater disinfection affects public health and compliance with the Safe Drinking Water Act and wastewater discharge requirements. This practical, three-day workshop provides up-to-date information about current disinfection practices. Learn how to control disinfection costs, operate and maintain disinfection systems, comply with regulations, and provide effective barriers against disease outbreaks.

Public Water Systems Operators use principles of hydraulics daily in the operation of their systems. The day-to-day operation of a water and wastewater system requires an understanding of hydraulic principles.

In this practical 3-day workshop, students will be introduced to important basic concepts of hydraulics and learn how hydraulics affects the components of both water and wastewater systems.

Take the mystery out of proper methods to install and maintain pipe, by understanding issues facing water and wastewater utilities with aging pipe infrastructure. Discover new ways to effectively control water loss. With up-to-date information on piping materials, components and fittings, learn ways to locate pipe and identify leaks. Students will also learn to identify methods to reduce pumping costs by applying skills gained by attending this workshop.
