Denver -- The American Water Works Association recently released two additional books to its relaunched Water System Operations (WSO) series with fully revamped versions of Water Distribution, Grades 1 & 2 and Water Distribution, Grades 3 & 4 . These guides join the WSO Water Treatment set that was released earlier this year.
AWWA’s WSO series provides the foremost test preparation materials for water operator certification. Additionally, it is now the only book series aligned with current Association of Boards of Certification (ABC) Need-to-Know criteria. ABC administers water operator certification testing for the majority of North America.
WSO Water Distribution, Grades 1 & 2 and Grades 3 & 4 are designed to assist water operators in preparing for their exams by focusing on core test content including regulations, specific distribution processes, water system design, and hydrants and valves. Test questions, full color graphics and illustrations, and links to free instructional videos are also included throughout each chapter to further assist students in their test preparation.
Water Distribution, Grades 1 & 2 and Water Distribution, Grades 3 & 4 are available in AWWA’s online store.
