Water
Pressure and Hydrant Flow Information
EBMUD is committed to provide reliable, adequate pressure and water flow for
all customers. Water pressure typically ranges from about 30 to 130 pounds
per square inch depending upon the elevation of a customer's service connection
within a particular pressure zone. The District has over 130 pressure
zones, most of which 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.

You will be charged $265 for each hydraulic model analysis request. If you need flow and pressure data for a fire service but do not meet the above criteria, you may request existing hydrant flow data at no charge in the next section.
