Catalog Course Description

A basic course in water distribution and treatment covering water quality control practices, water sources, public health aspects of water regulations, supply, water treatment arithmetic, chemical treatment, filtration, corrosion, disinfection, tastes and odors in water, water system operation and maintenance, valves, pipes, pumps, and meters. The material covered in this course will be helpful to those preparing for the California State Water Resources Control Board (SWRCB) D-1 and D-2 Water Distribution Operator's Certificate examinations and the T-1 and T-2 Water Treatment Operator's Certificate examination. 54 lecture hours.

Course Objectives

  • Calculate pipe and vessel volumes and hydraulic measurements used in the water supply industry.
  • Identify corrosive factors within the water piping systems and recommend corrective action.
  • Articulate the disinfection and water testing processes and regulatory controls.
  • Discern and apply State and Federal regulations related to the public water supply and treatment industry.
  • Describe the use of the various valves and meters used within water distribution systems.
  • Explain the basic factors of pump operations necessary in the water industry.
