Dual Service allows for one oversized water meter, combining both domestic use and fire protection for single-family residences and some multi-family residences (as approved by the local fire marshal) in lieu of a domestic water meter and dedicated private fire service. The California Building Code requires automatic fire sprinkler systems in all new construction. A dedicated private fire service is required for all commercial buildings and other multi-family residential buildings as determined by your local fire marshal.
Disclaimer: Applicants for new water service will find this information helpful to understand the process of applying for a new combination water and fire service (dual service). These charges and fees are presented only as guidelines for cost estimates. Final quotations will not be issued until a properly completed application is submitted. All applications for water service are subject to review and approval by EBMUD. All requests for preliminary estimates or quotations must include an address, accurate location of the parcel to be served, and the proposed use of the premises. Availability of an existing main, unusual installation conditions and contaminated soil conditions may increase your final cost.

STEP 2: EBMUD provides cost estimate
EBMUD calculates cost of water service(s) and sends estimate to applicant.
STEP 3: Applicant remits payment
Applicant pays installation fee either in person or by mail. The applicant must pay all charges before the job will be scheduled. Please call the New Business Office to schedule an appointment to pay in person.
STEP 4: EBMUD obtains permit
EBMUD applies for either a city, county or state encroachment permit for street work at your site.
STEP 5: EBMUD installs meter
After receiving the encroachment permit, EBMUD schedules the meter installation.
A service for both domestic use and fire protection (dual service) has a larger lateral and meter than a standard domestic service to meet the flow demand for fire prevention. The standard lateral size is 1-1/2" and the meter size for dual service depends on the domestic demand for your property and flow demand for fire prevention, but is typically 1” to 1-1/2”. The Meter Size Worksheet helps EBMUD determine your new meter size(s). Your contractor or a qualified plumber should be consulted regarding your particular service requirements.
Installation of your new service will be completed within 6 to 8 weeks after receipt of full payment and required encroachment permit, if applicable. Note: Installation time is contingent on District work load, project size, and site conditions. During peak season, completion schedule may be impacted.
The cost of service depends on the size of the water meter, type of service, and location of the property. The total cost will be the sum of the following:
- Installation Fee
- System Capacity Charge
- Wastewater Capacity Fee*
- Front Foot Charges*
- Contaminated Soils*
- Account Fee
- Annexation Fees*
