Intended for persons associated with wastewater treatment plant operations and management (O&M), the course described is designed to address significant factors contributing to poor plant performance. The training materials discuss the interaction between several potential causes of problems and stress the need for comprehensive corrective action programs. Following a set of guidelines for the course director, 15 units of instruction are presented. These contain a total of 49 lessons and are generally offered as a 30-35 hour short course. In addition to the 12 units which deal directly with O&M problems are introductory and closing units and a unit which examines elements of the troubleshooting process. Each lesson plan includes the purpose, trainee entry-level behaviors, objectives, schedule, materials, classroom setup, lesson outline, and references. All materials that appear in a trainee's notebook or which should be reproduced as handouts are located after corresponding lessons. Instructional approaches range from lectures to simulations, analyses of records, and small group problem-solving sessions. The course is designed to help trainees develop a set of basic tools to apply in a variety of O&M situations. (WB)
