Academic Honesty, Course Expectations, and Copyright

Office of Water Programs (OWP) courses are administered and monitored by California State University, Sacramento (Sacramento State), and, therefore, are subject to the Sacramento State Academic Honesty Policy Participants in our courses are licensed operators and individuals who are aiming to be licensed. They have a crucial role in maintaining the integrity and value of our courses to the profession and the communities they serve. OWP works to protect the integrity and accreditation of courses and materials by setting expectations for students and investigating violations of academic honesty and copyright infringement. This protection may include presenting different versions of course materials (including, but not limited to, exam questions) to different students.

As a professional participant enrolled in our courses, it is expected that all course work will be completed by you and that the course work demonstrates your skills and knowledge of the subject matter. As part of an educational community, OWP expects that all course participants protect the integrity of the curriculum and student grades. Activities that violate Sacramento State's academic honesty policy and OWP course expectations include sharing exam questions and answers, purchasing or acquiring exam questions and answers from others, turning in exams or other course work completed by others as the student's own, or any other misrepresentation of the student's knowledge or skills.

In addition, OWP course materials—including training manuals and exam questions and answers—are copyrighted by OWP. Publishing, reproducing, selling, or otherwise distributing any of OWP's materials without prior, explicit permission from OWP (except as allowed by law) is a violation of copyright.

By participating in OWP courses and submitting exams for grading, you acknowledge that you have read and understand OWP's academic integrity, course expectations, and copyright statement.

How do I become a water or wastewater operator?
What courses I should take?
If you're just beginning to think about operator training, here's some certification information to help you get started. Another resource for information about working in the water sector is Work for Water.
How do these self-study training courses work?

Study the course material at your own pace. Manuals may include self-study course instructions and recommendations for long-term learning near the table of contents to help you successfully complete the course. Most manuals include section questions, a Chapter Review, and an Answer Key that can be used to test your knowledge of the material as you move through it. We recommend that you familiarize yourself with the material in each chapter, using the section questions to assess your understanding of the material. Then answer the Chapter Review questions. Check your answers against the Answer Key (at the back of the book) and review the material about any questions that you answer incorrectly.

When enrolled in a course, you can complete your objective tests when you are satisfied with your mastery of the chapter content. (Check the course time limit to be sure that you submit all tests before your enrollment expires.) Testing instructions are provided when you enroll in a course.

How much time is allowed to finish each course?
  • Courses worth 0.6 to 3.0 continuing education units (CEUs) must be completed within three (3) months of the date of enrollment.
  • Courses worth 3.1 to 9.0 CEUs must be completed within six (6) months of the date of enrollment
  • Certificate program courses for academic credit must be completed within six (6) months of enrollment.
How long will it take me to study for the course?
The time to complete each course depends upon each person. Each individual sets his or her own pace, but we recommend that you establish a regular schedule such as one or two evenings a week or on Saturday mornings. Most students require from 50 to 150 hours of study to complete each course.
Why do you stop grading older editions after a new edition
is published?

New editions of our courses are developed to ensure that students receive the most current information about processes, regulations, and technologies. Once an edition has been replaced with a more current version, it is no longer appropriate to grade tests that are based on outdated material. Courses that have been successfully completed may only be repeated when a revised edition becomes available.

During the transition period from one edition to the next (usually 6 months) we grade both versions to accommodate those students who had just begun the course when the new edition became available.

To ensure the best test results, it is important that the edition of the manual you are using matches the edition of the course you are enrolled in.

How do I access the eText?

Each training manual published in 2017 or later by Pearson includes an access card with an access code and instructions for registering and signing into the eText Portal. Once in the portal, select the Register button for the manual you have purchased. After you have accepted the License Agreement and Privacy Policy, enter the access code from the access card in the next screen. After you complete the registration, you can use the Sign in button to return to the eText.

How do the online courses work?

Most online courses accompany the print training manual. Each course assigns readings from the training manual and delivers related lessons, videos, interactive exercises, math practice activities, and online exams over the Internet. Please be sure you can meet the System Requirements before completing your purchase.

The online math courses provide step-by-step explanations of calculations operators use on the job and the concepts behind the calculations. Each course is presented in both US customary and metric units and students can select the unit system to use for the final exam. Online math courses do not assign readings from the associated training manual. Students are encouraged to purchase the training manual for more information about the processes and procedures the math concepts and practice problems apply to. Watch our preview video for more information on the online math courses.

For a complete list of online offerings, see our Online Courses page. (Note to Texas and Washington operators: Your states require that your exams be proctored and that an affidavit be signed by your proctor. After purchase, you will receive detailed proctoring instructions.)

Can I take more than one course at a time?

You may take more than one course at a time, but remember that the course time limits apply to each course you order. That means that if you enroll in two courses with 6-month time limits at the same time, you must finish both within the same 6-month period. Enrollment time limits begin on the date you place your order.

Can instructors order instructor guides for courses?
Instructor guides are double-sided loose-leaf pages printed in black and white. They contain sample questions for each chapter within the designated course, which can serve as discussion questions in the classroom. It's important to note that instructor guides are not an instructor version of our course manuals and they do not contain our course exam questions.

If you are interested in purchasing instructor guides, please submit the following information on school/company letterhead to for credential evaluation and verification:
  1. Qualifications of the instructor(s) for whom you are requesting instructor guides, accompanied by their resumes and class schedules if applicable (for those teaching at a college/university).
  2. State the intended use of the instructor guides, including the scope of their use (e.g., teaching courses) and the location(s) where courses will be held.
  3. Specify the titles of the manuals/courses for which you wish to procure instructor guides, along with the respective names of the instructors requesting each
    manual title.
Some of our larger manuals, such as, Operation of Wastewater Treatment Plants, Volume 1, and Operation of Wastewater Treatment Plants, Volume 2, have been split into multiple courses. For instance, Operation of Wastewater Treatment Plants, Volume 1, comprises three courses—A, B, and C—each with its own separate instructor guide.

Qualified and verified instructors can purchase instructor guides for $35.00 per course. These items are non-refundable and orders must be paid in full prior to shipment.
For any additional questions, please email
Can I request a version of a training manual that is ADA accessible?

Some students may request a pdf version of our training manuals that can be read aloud by screen readers as an ADA accommodation.

To request an ADA accommodation for a textbook purchased directly from OWP, please send an email to with your request and an attached letter from a medical provider verifying a disability that requires accommodations. Please note that the letter can be a general verification without disclosing a specific disability.
