WTECH 182 Pumps and Pumping Systems
Course Description
Pumps and pump piping systems found in water supply
and wastewater facilities. Common types of pumps will
be identified. Operational theory, application, maintenance
and troubleshooting of centrifugal pumps will be emphasized. Piping systems for common pumping applications will also
be discussed. (3 credits)
Learning Outcomes
Content-Specific Learning Outcomes -Students will
demonstrate proficiency with these components of the course
content:
- Ability to recognize types of pumps typically found in water and wastewater utilities.
- Knowledge of general hydraulic and mechanical principles related to centrifugal pumping systems.
- Knowledge of star-up and shut-down procedures for centrifugal pumping systems.
- Ability to perform general maintenance and repair s on centrifugal pumping systems.
- Ability to discriminate between normal and abnormal operating conditions for centrifugal pumping systems.
Course content learning outcomes will be demonstrated by assignments and summary tests.
Campus-Wide Learning Outcomes: Critical Thinking – Competent employees need critical thinking skills to be successful in the workplace. Students in this course will be challenged to think critically. Critical thinkers:
- Are active readers who read texts closely, noting key ideas, and investigating unfamiliar words.
- Are active listeners, paying close attention to lectures and discussions, trying to understand statements from a speaker's perspective, and trying to understand assumptions behind statements.
- Ask questions, seeking to understand and evaluate information presented.
- Know how to learn; they draw upon experience and/or prior knowledge, interpret and apply new knowledge and experience.
- Recognize and solve problems; they identify problems, analyze possible causes, and generate solutions.
- Apply reasoning skills; they identify and apply facts
and principles, examine information for relevance and accuracy.
Campus-wide learning outcomes will be demonstrated by assignments and summary tests.

Test Format
For online courses that are primarily reading assignment and written project based, summary tests may include matching, true/false, multiple choice, simple sketching, and essay questions. Summary test questions will be based on the assigned material and will ask you to demonstrate your understanding by applying the material.
For online courses that use problems and calculations as the primary assignments, summary tests will ask you to work problems similar to those in your assignments. Formula and conversion sheets will be provided with each test.
Summary tests will be closed-book; you will not be allowed to bring any written material to the testing session.
Time Limit
Summary tests are intended to take approximately one hour to complete; you may utilize up to two hours if you wish.
Taking Tests at the GRCC Testing Center
If you live within sixty miles of the Green River Community College Auburn campus, your tests will be available in the GRCC Testing Center, located in the Rutkowski Learning Center, Room 173 (RLC 173).
The Assessment & Testing Center web page has information about testing procedures for Green River classes as well as quarterly hours. Please note that the Testing Center will be closed on holidays when the campus is closed. The Testing Center may be reached by telephone at (253) 833-9111, extension 2650.
Taking Tests Using a Proctor
If you live more than 60 miles from the Green River Auburn, Washington campus, you may arrange for a local proctor to administer your tests. Possible resources for proctoring services include a local college, community college, technical school or library. It is the student's responsibility to arrange for a proctor prior to the second week of class.
You may complete summary tests at any location that is mutually agreeable to you and your proctor. Proctors will be asked to ensure a quiet and relatively undisturbed location.
Once you have identified a proctor, please submit the following information to the instructor, Larry Shenk:
- Proctor's name
- Proctor's job title
- Complete mailing address (including zip code)
- Telephone number
- Fax number, if available
- e-mail address, if available
Summary tests will be sent directly to the proctor. The proctor will be asked to return the summary tests as soon as they are completed.
When to Complete Tests
You may complete summary tests at any time prior to midnight on the day the test is due. Be sure to check the course schedule for due dates. If you are taking tests in the GRCC Testing Center, be sure to allow sufficient time to complete the test before the center closes.
What to Bring to a Testing Session
Bring a pen or pencil, calculator (if your course includes math problems), and picture identification (a valid Driver's License is preferred). The proctor will be asked to submit information from your picture identification with each summary test. Also, be sure you can confirm the complete course number, title and topic(s) to covered on the test.
Test Verification
It's very important to make sure you select the appropriate test from your test proctor. If you select the wrong test, you will not have the opportunity to re-take the test (whether you complete it or not). Carefully review the cover sheet of each test before signing for the test. Your signature on the test cover sheet indicates that you've selected the appropriate test. Each test cover sheet will include the following statement and will require your signature:
ATTENTION STUDENT:
Please confirm that this is the appropriate test! Be sure to confirm the course number/title as well as the test topics listed at the top of this cover sheet. By signing below, you agree that the appropriate test has been selected. Please note: If you sign for the wrong test, you will not have the opportunity to re-take the test (whether you complete it or not) at a later time.
ATTENTION PROCTOR:
Once the student has signed for this test, it is considered a "viable" test (whether or not the student completes it) and it must be returned to the instructor. If, after signing for the test, the student determines the wrong test has been selected, you may re-issue the correct test. Thank you for your cooperation.
What Will be Provided at a Testing Session
The summary test and formula/conversion sheets, if appropriate, will be provided.
