Water Flow Design

You are here

San Jose Water Company will supply water flow design information for all projects within its service area. The information is produced using hydraulic modeling software. This information is used by individuals, contractors and insurance companies for purpose of designing irrigation and fire sprinkler systems. Design information is also used by the local fire jurisdictions in determining if adequate fire protection is available from existing fire hydrants for new and remodel projects.

To obtain water flow design information, e-mail your request to: engineering.dept@sjwater.com. Please include 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

Flow availability requests take 5-10 business days to process and are handled in the order they are received. You will be notified by e-mail of our computer-simulated results. If requested, the results can also be mailed to you.

If you are inquiring on the status of a previous request or unable to e-mail the information, you can call 408-918-7362. Please leave your name, location of the request and your phone number.

For flow information from existing fire hydrants requested by fire jurisdictions, please include any and all comments on the Santa Clara County Land Use Comments and Requirements form.
