Coronado gets water through a City contract with California American Water, which requires yearly backflow testing, and the City makes business owners responsible for the sewer lateral up to and including its connection to the main. Building Services can issue some plumbing permits over the counter by email. Call the number on this page to be connected with a local plumber in Coronado.
Coronado's commercial property runs from hospitality near the Hotel del Coronado to restaurants and shops along Orange Avenue and residential communities in the Coronado Cays. Busy kitchens, heavy restroom use and salt air drive most calls, and a few local rules decide who pays for what.
What to do now
- If water is spreading, close the main shutoff or the valve that feeds the fixture or floor.
- If anyone smells gas, get everyone out first, then from a safe spot call 911 and SDG&E at 1-800-611-7343.
- For a break at the meter or in the street, call California American Water at 1-888-237-1333, which takes emergencies at any hour.
- Stop running water into a drain that is backing up and keep staff away from overflowing floor drains.
- Check the date of your last backflow test; Cal Am expects required devices to be tested every year.
- Take photos and note when the trouble started for the plumber and any landlord follow-up.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Guest rooms or restrooms short on hot water at peak times | Scale in the tank, a failing burner or element, or a heater too small for demand |
| Kitchen drains slow after weekend service | Grease coating the line or a full interceptor |
| Several floors or suites backing up together | A blockage or break in the building's sewer lateral |
| Pitted hose bibs and stiff exterior valves | Salt air corroding exposed brass |
| Water spitting from a backflow relief port | A fouled check or relief valve |
Cost factors in Coronado
Sewer work can run larger here than owners expect. The City's lateral policy puts the property owner in charge of the line up to and including the connection to the City main, so a break near the street is still the owner's repair. Camera inspection usually comes first to find where the problem is.
Permits can move quickly for routine work. The Building Services Division at 1825 Strand Way (619-522-7331) offers over-the-counter emailed permits for same-location water heater and tankless change-outs and for gas line repairs. Larger alterations take longer.
Water conditions add to maintenance costs. Cal Am's Coronado system buys treated City of San Diego water that is chloraminated, with source-plant hardness from 145 to 280 ppm (about 8.5 to 16.4 grains per gallon). For irrigation and fire sprinkler services, Cal Am wants an approved backflow device right behind the meter unless its cross-connection specialist approves otherwise, and continued noncompliance can lead to disconnection. Other cost drivers include after-hours scheduling around guests and diners, access through finished ceilings, and replacing salt-worn exterior parts.
