Call the City for problems in the public water system and at the meter; call a plumber for problems in your own pipes.
The City of Fountain Valley runs its own water utility. In 2025 the City's water was 100% groundwater pumped from the Orange County Groundwater Basin, which the Orange County Water District (OCWD) manages. Normally the mix is about 85% groundwater and 15% imported water from the Metropolitan Water District of Southern California.
The City lists two main water numbers on its household utilities page:
For water quality questions, the City's water quality staff and Field Services are at 714-593-4600, and the City publishes an annual water quality report. The City's FAQ also notes that its lead service line inventory found no lead or galvanized service lines requiring replacement.
If you are not sure which side of the meter a leak is on, call Water Services and ask. If it is on your side, we can find it. EPA WaterSense suggests a simple meter test: check the meter before and after a two-hour period with no water use. If it moves, you probably have a leak. Our leak detection service takes it from there.
Fountain Valley's sewer system has three owners: you own the lateral from your house to the main, the City runs the local public sewers, and OC San runs the regional system and treatment plants.
The City's sewer guidance is clear on the first part. Property owners are responsible for maintaining their private sewer laterals, from the building to the public sewer main, including any part under the sidewalk or street. The sewer agency maintains the local, public and regional sewer lines.
The City has its own Sewer Division, which handles sewer and storm drain work, and the Southpark Specific Plan describes sewer service in the city as provided by the City of Fountain Valley and the Orange County Sanitation District. OC San is a public agency that collects, treats and recycles wastewater for about 2.6 million people in central and northwest Orange County. Its administrative offices and primary plant, Plant No. 1, are in Fountain Valley next to the Santa Ana River.
| Part of the system | Owner | Who to call when it fails |
|---|---|---|
| Drains, toilets and pipes inside the house | Property owner | A plumber |
| Sewer lateral from the house to the main, including under the sidewalk and street | Property owner | A plumber |
| Local public sewer main under the street | The local sewer agency (City of Fountain Valley) | City after-hours line (714) 593-4485, or the spill hotline |
| Regional trunk sewers and treatment plants | OC San | OC San Control Center (714) 593-7025 |
If sewage is coming up a floor drain, tub or toilet and the neighbors are fine, the problem is almost always in your lateral or your house drains. The City's guidance for a suspected backup or leak from your property is to contact a licensed plumber. That is our drain cleaning and sewer line repair work.
If sewage is coming out of a manhole in the street or a cleanout and running toward the gutter, report it. The City's guidance says a spill seen at a cleanout or manhole goes to your sewer agency, or to the county's 24-hour pollution hotline at 1-877-89-SPILL (1-877-897-7455). The county also takes reports online through myOCeServices.ocgov.com. OC San says that if a spill is not part of its system, you should contact your city.
The City asks plumbers to contact the sewer agency before pushing roots from a private lateral into the public main. We follow that. Clearing your line should not create a blockage for the street.
The City's sewer guidance lists four steps, in this order.
Turn off the main water supply or stop all water use. Every flush and every faucet adds to the spill.
Have a plumbing professional clear the blockage and make repairs. Call us at (657) 669-4766, any hour.
Sewage carries bacteria. Keep children and pets out of the area until it is cleaned up.
When it is safe, place sandbags or other material in the flow path to keep sewage out of the storm drain system.
If you smell gas, leave the building first, then call SoCalGas at 1-800-427-2200 or 911 from outside.
Southern California Gas Company supplies natural gas in Fountain Valley. The City lists SoCalGas's general number, (800) 427-2000, for service and billing. For a gas leak or a damaged gas line, use SoCalGas's emergency line, 1-800-427-2200. SoCalGas has also said that even minor damage to a gas line or its coating should be reported right away, because a small gouge or dent can lead to a break or leak later.
Once SoCalGas has made the situation safe, the repair on your side of the meter is plumbing work. Gas piping from the meter to your appliances belongs to the customer. That includes the line to the water heater, range, dryer, furnace, barbecue, fire pit and pool heater. Repairs and new gas lines need a City permit. See our gas line plumber page.
Southern California Edison (SCE) supplies electricity in Fountain Valley, and power outages go to SCE at (800) 611-1911. The City's utilities page says not to call 911 for normal outages. SCE's general service number is (800) 655-4555.
Plumbing and power cross paths more often than people think. A power outage stops electric water heaters, tankless heaters that need electricity to fire, sump and ejector pumps, and recirculation pumps. When power comes back and a tankless heater will not restart, that is a call for us. A sparking line or downed wire is not. SCE advises that if you hit a line or find an electrical hazard, stay away and call 911 or SCE at 1-800-611-1911.
Call 811 or request a ticket online at least two working days before you dig, not counting the day you call.
DigAlert is the name for Underground Service Alert of Southern California, the free service that has utilities mark their underground lines before you dig. SCE notes that California law sets the two-working-day notice, and that the marking is free. SoCalGas reminds customers that this applies to small jobs too: fences, decks, planting or removing large trees.
Outline where you plan to dig with white paint, white-flagged stakes, chalk, or even flour.
Call 811 or schedule online at least two working days ahead.
Utilities mark their electric, gas, water, phone and fiber lines. Do not start until they do.
SoCalGas says to use only hand tools within two feet on each side of a marked gas line. SCE advises hand tools within 18 to 24 inches of a utility's outside edge.
Leave flags, stakes and paint until the project is finished.
Republic Services handles trash collection in Fountain Valley, at (714) 847-3581. The City's utilities page links to Republic's holiday pickup schedules and public dump information.
Grease is where trash and plumbing meet. The City asks residents not to pour fats, oils and grease (FOG) down drains. Its sewer guidance says to let grease cool, pour or scrape it into a metal can, and dispose of the full can properly. Grease that goes down the sink hardens in your lateral and in the public main, and it is one of the most common causes of the backups we clear.
Restaurants and other food service facilities have their own rules under the City's grease ordinance, including grease interceptors and regular service. Our commercial plumbing page and the Southpark page cover those.
The Fountain Valley Building Division issues plumbing permits from City Hall at 10200 Slater Ave. Its phone is 714-593-4429, and the counter is open Monday to Thursday, 7 a.m. to 6 p.m., closed Fridays. The City requires a permit before installing, altering, repairing, removing or replacing a plumbing system. Our permit guide explains which jobs need one.
Backflow testing runs through the City's cross connection control program with the Orange County Health Care Agency. Questions go to the City's Water Quality Technician at 714-593-4624. Completed test forms go to the Public Works and Field Services Division at 17300 Mt. Herrmann St.
City Hall's main number is 714-593-4400.

Yes. Contact 811 at least two working days before you dig, not counting the day you call. It is free. Utilities mark their lines, but your own gas, water and sewer lines are not marked, so a plumber or locating service has to find those.
Call a plumber for anything on your side of the water meter, anything in your sewer lateral, and any fixture or appliance. If your neighbors have water and you do not, or only your drains back up, the problem is likely yours.
Republic Services, at (714) 847-3581. Do not pour cooking grease down the drain; the City asks you to cool it, put it in a metal can and throw it away.
