Water Flow Design

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.

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.
