Water Pressure and Hydrant Flow Information

EBMUD is committed to providing reliable, available pressure and water flow for all customers. Water pressure typically ranges from 30 to 130 pounds per square inch depending upon the elevation of a customer's service connection in a particular pressure zone. Most of EBMUD's more than 130 pressure zones include one or more treated water storage tanks. Water flow is primarily determined by the size of a customer's service connection and the water pressure at that connection.

Flow and Pressure Information for Fire Service for Commercial Buildings and Multi-Family Structures of Five or More Units

You must request water pressure and flow information for the installation of a new fire sprinkler system through our New Business Office. This includes:

  • design/redesign of a fire sprinkler system or upsizing of an existing fire service, and
  • fire service for a commercial building, or
  • fire service for a multi-family structure of five or more units.

View the online Fire Service Flow and Pressure Request form to request pressure and flow information for a fire service.

There is a fee of $369 for the flow and pressure request. Each request can contain up to three proposed locations for the same project. Additional locations or a different job site require payment of an additional fee. The fee can be paid online or in person. If you prefer to pay in person, please print, complete and deliver the Fire Service Flow and Pressure Request form with your payment to the EBMUD New Business Office at 375 11th Street, First Floor, Oakland. The EBMUD Planning Office will conduct a hydraulic model analysis to determine available flow and pressure. This information will be emailed to you with a Statement of Design Criteria. The Statement of Design Criteria must be completed by your fire sprinkler contractor and submitted with your fire service application.

If you need flow and pressure data for a fire service for something other than a commercial building or a multi-family structure of five or more units, you may request existing hydrant flow data at no charge (see Fire Service Flow and Pressure Request form below).

NOTE: This is not a fire service application. You must also complete the Water Service Application Packet to apply for the fire service after you obtain the flow and pressure data.
