Hydrant Flow Tests
Fire hydrant flow tests determine the flow rate and pressure at a location within Tualatin's water distribution system. Flow tests are used to determine water availability in planning for firefighting activities, fire sprinkler systems, or domestic water demand.
All hydrant flow tests must be permitted through the City to ensure the protection of city infrastructure and public health. Hydrant flow tests cost $250 per test.
Your staff must be present at the time of the test. City staff do not conduct the test. They only operate the hydrants.
How do I apply for a hydrant flow test?
Hydrant flow tests are permitted through eTRAKiT, the City's electronic permitting system. Click here to apply for a Hydrant Flow Test.
FAQ
What do I need to bring to the test?
- Water diffuser; no straight pipes are allowed
- Hydrant valve
- Several lengths of fire hose; the need will vary depending on hydrant location/access. We do not flow water from the main port.

- Hydrant wrench
- Pitot or other pressure gauges for both the static and flowing hydrant
- At least two staff to operate testing equipment at both hydrants
If the applicant is not fully prepared to conduct the flow test a reschedule may be required.
Why is City staff present?
City staff operates the hydrants to prevent damage to City infrastructure and provide technical knowledge of the distribution system. City staff will not operate testing equipment. Please have enough staff present to cover both hydrants.

Hydrant flow tests cost $250 per test.
