Water Flow Design Information

San Jose Water will supply water flow design information for all projects within its service area. We produce this information using hydraulic modeling software. Individuals, contractors and insurance companies may use it to design irrigation and fire sprinkler systems. Local fire jurisdictions also use design information in determining if adequate fire protection is available from existing fire hydrants for new and remodel projects.

E-mail your request to: engineering.dept@sjwater.com. Please include the words WATER FLOW in the subject line and all of the following:

- Requestor's name
- Company name if applicable, company mailing address, phone number, and e-mail address
- Street name and address of the project
- Nearest cross street to that location
- A sketch map of where the flow information is requested

For flow information from existing fire hydrants requested by fire jurisdictions, please include any and all comments from the Fire Department.

Information Request Timing

Flow design information requests take 5-10 business days to process and we handle them in the order we receive them. We will notify you by e-mail of our computer-simulated results. Upon your request, we can also mail you the results.
