Water problems: City Water Services or a plumber?

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:

  • Water Services, (714) 593-4420. Starting or stopping service, paying bills, e-bills, meters and leak checks.
  • Water Emergency, (714) 593-4485. Use it for water main breaks, water running in the street and other urgent water problems, especially after hours. The City's grease ordinance page also lists this number as the Public Works after-hours line.

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.

Usually the City

  • Water bubbling up in the street or gutter
  • The whole street has no water or low pressure
  • Water leaking from the meter box itself
  • Questions about the meter reading or a bill
  • Discolored water from every tap after street work

Usually a plumber

  • A burst pipe inside the house or garage
  • The meter is spinning with every fixture off
  • A wet spot in the yard between the meter and the house
  • Low pressure or no hot water in one home only
  • A leaking water heater, toilet or faucet

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.

Sewer problems: your lateral, the City main or OC San

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.

Backup inside the house

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.

Spill in the street

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.

A note for plumbers

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.

What to do during a sewer spill at your home

The City's sewer guidance lists four steps, in this order.

  1. Stop the water

    Turn off the main water supply or stop all water use. Every flush and every faucet adds to the spill.

  2. Get the blockage cleared

    Have a plumbing professional clear the blockage and make repairs. Call us at (657) 669-4766, any hour.

  3. Keep people and pets away

    Sewage carries bacteria. Keep children and pets out of the area until it is cleaned up.

  4. Protect the storm drain

    When it is safe, place sandbags or other material in the flow path to keep sewage out of the storm drain system.

Gas leaks: SoCalGas first, then a plumber

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.

  • Leave the house and keep others out.
  • Do not switch lights or appliances on or off, and do not use anything that could spark.
  • Call SoCalGas at 1-800-427-2200, or 911, once you are outside and away from the smell.
  • Wait for SoCalGas to clear the area before going back in.
  • Call a licensed plumber for repairs to your own gas piping.

Power outages and electrical hazards: SCE

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.

Before you dig: DigAlert 811

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.

  1. Mark the dig area

    Outline where you plan to dig with white paint, white-flagged stakes, chalk, or even flour.

  2. Contact 811

    Call 811 or schedule online at least two working days ahead.

  3. Wait for the marks

    Utilities mark their electric, gas, water, phone and fiber lines. Do not start until they do.

  4. Hand dig near marks

    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.

  5. Keep the marks in place

    Leave flags, stakes and paint until the project is finished.

Trash, grease and what not to put down the drain

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.

Permits, backflow and other City offices

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.

When to call us instead

Call a plumber when the problem is on your side of the meter, in your sewer lateral, or in any appliance or fixture in your home or building.

Questions Fountain Valley homeowners ask

Who do I call for a water main break in Fountain Valley?

Call the City of Fountain Valley water emergency line at (714) 593-4485. For regular service and billing questions, Water Services is at (714) 593-4420.

Who do I call if sewage is coming out of a manhole?

Report it to the Orange County 24-hour pollution hotline at 1-877-89-SPILL, or to the local sewer agency. In Fountain Valley, the City's after-hours public works line is (714) 593-4485. For a spill from an OC San regional line, OC San's Control Center is at (714) 593-7025.

Who is responsible for the sewer line from my house to the street?

You are. The City says property owners maintain the private sewer lateral from the building to the public main, including the part under the sidewalk and street. Read our sewer lateral guide.

What is the difference between OC San and the City sewer?

The City of Fountain Valley runs the local public sewers under city streets. OC San, the Orange County Sanitation District, runs the regional sewers and treatment plants, including Plant No. 1 in Fountain Valley, and serves about 2.6 million people.

What number do I call if I smell gas in Fountain Valley?

Leave the building first, then call SoCalGas at 1-800-427-2200 or 911 from outside. Do not switch anything on or off. A plumber handles repairs to your own gas piping after SoCalGas makes it safe.

Who do I call for a power outage in Fountain Valley?

Southern California Edison takes outage reports at (800) 611-1911. The City says not to call 911 for a normal outage. Call 911 for sparking or downed lines.

Do I need to call 811 before digging in my yard?

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.

When should I call a plumber instead of the City?

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.

Who picks up trash in Fountain Valley?

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.
