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.
There are two methods for getting flow and pressure results: 1) Hydrant Flow Test and 2) Hydraulic Modeling Analysis. Please read carefully before you proceed with a flow and pressure request to prevent delays in receiving your results.
Hydrant Flow Test and Pressure Information Requests
You may request hydrant flow test data for general inquiries, irrigation services, insurance assessments, or to report a water pressure problem. You may also request hydrant flow test data for the installation of fire sprinkler systems for a single family home, a duplex, a triplex or a fourplex by using the Water Pressure Information Request online form or by calling 1-866-403-2683. These requests are considered non-emergencies and will be responded to in 15 business days. For fire services for commercial buildings and multi-family structures greater than a fourplex, please proceed to the next section.
Flow and Pressure Information for Fire Service for Commercial Buildings and Multi-Family Structures
You may request water pressure and flow information for the installation of fire sprinkler systems for commercial buildings and multi-family structures greater than a fourplex by using the online Fire Service Flow and Pressure Request form. This includes design or redesign of a fire sprinkler system or upsizing of an existing fire service. The fee is $369 for the flow and pressure request using hydraulic modeling analysis. EBMUD's Planning Department will conduct a hydraulic modeling analysis to determine the available flow and pressure at your project site. This information will be emailed to you with a Statement of Design Criteria in approximately 10 business days. The Statement of Design Criteria must be completed by your fire sprinkler contractor and submitted with your fire service application.
You may request up to three possible connection points within a project site. Additional connection points or a different project site require a separate request and fee payment. A connection point is measured from the centerline of the nearest cross street to the front of the property where the fire service is connected to EBMUD's water line.
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.
