Course Description

Teaches principles, practices and desired funtion and operation of a variety of wastewater treatment unity processes.  Evaluates the operation of processes by determination of the information and testing required for evaluation and performing the subsequent necessary calculations.

Statement of Broad Goals/Units and Specific Objectives

This course will analyze the different processes used in the treatmentt of wastewaters.  Emphasis will be put on biological treatment devices and mechanisms.  An important secondary objective in this course is to help prepare students for the state certification exam for wastewater plant operations.


  • Students are required to have certain math skills, such as calculate chemical dosages, manipulate
    formulas and equations, calculate areas and volumes, convert between measuring systems, apply basic
    math concepts to the profession, calculate volumes from pump running times, calculate averages and
    geometric means, plot and interpret graphs, and calculate chemical quantities for budget purposes.
  • Certain computer skills are also required, such as using an operating system, spreadsheet software,
    word processing packages, possess a knowledge of PLC at an introductory level, demonstrate
    keyboarding skills, access data from CD ROM, and use the Internet at a basic level

    sampling techniques, describe lagoon inspection and maintenance procedures, perform lab test
    procedures, interpret lab test results, describe clarification processes, demonstrate an awareness of
    federal and provincial regulations and license requirements, describe different types of biological
    treatment systems, describe effects of waste discharge on receiving environment, describe wastewater
    sources and characteristics, describe methods of odor control, describe solids treatment, handling and
    disposal, describe a preliminary treatment process, describe methods of wastewater disinfection,
    demonstrate an awareness of new and innovative technology, explain reclamation of final effluent,
    describe nutrient removal processes, describe industrial treatment processes, and describe control
    strategies of filamentous micro-organisms.
  • Certain wastewater collection skills are also required, such as identify safety hazards with waste
    water collection, describe safety procedures specific to wastewater collection, describe proper
    sampling techniques, describe methods used to control traffic flow, describe sewer cleaning methods,
    describe sewer inspection procedures, demonstrate an awareness of hazardous waste regulations,
    describe the use of sampling equipment, describe basic repair of sewer lines, explain lift station
    operation and maintenance, calibrate pumping equipment, identify system deficiencies, describe
    installation of service connections, identify and describe different sewer systems, describe low

    odors, explain interaction with other facilities, describe tracer study procedures, dye and smoke,
    describe an inverted siphon,  describe storm water management methods, and demonstrate an
    awareness of trenchless repair procedures.
  • Students should also have certain computer literacy skills, such as using programs, spreadsheets,
    search for folders, and use the mouse drag and drop techniques.

Instructional Methods

Students are required to read the lessons from the book, along with any lessons that are on the Internet.  Any questions that are on the website must be answered and turned in to Harriett Long at Mountain Empire Community College.  Water/wastewater plant visits are also a part of the teaching methods used in this course.
