What is a Sewage Spill?

Sewage spills occur when the wastewater being transported via underground pipes overflows through a manhole, cleanout, or broken pipe. Sewage spills can cause health hazards, damage to homes and businesses, and threaten the environment, local waterways, and beaches.

Common Causes of Sewage Spills

Grease builds up inside and eventually blocks
sewer pipes. Grease gets into the sewer from food establishments, household drains, as well as from poorly maintained commercial grease traps and interceptors. Grease is the most common cause of pipe blockages.

Structure problems caused by tree roots in the lines, broken/cracked pipes, missing or broken cleanout caps, or undersized sewers can cause blockages.

Infiltration and inflow (I/I) impacts pipe capacity and is caused when groundwater or rainwater enters the sewer system through pipe defects and illegal connections.

You Are Responsible for a
Sewage Spill Caused by a Blockage
or Break in Your Sewer Lines!

Time is of the essence in dealing with sewage spills. You are required to immediately:

Control and minimize the spill. Keep spills contained on private property and out of gutters, storm drains, and public waterways by shutting off or not using the water.

Use sandbags, dirt and/or plastic sheeting to prevent sewage from entering the storm drain system.

Clear the sewer blockage. Always wear gloves and wash your hands. It is recommended that a plumbing professional be called for clearing blockages and making necessary repairs.

Always notify your city sewer/public works department or public sewer district of sewage spills. If the spill enters the storm drain also notify the Health Care Agency. In addition, if it exceeds 1,000 gallons notify the Office of Emergency Services. Refer to the numbers listed in this brochure.

You Could Be Liable

Allowing sewage from your home, business or property to discharge to a gutter or storm drain may subject you to penalties and/or out-of-pocket costs to reimburse cities or public agencies for clean-up and enforcement efforts. See Regulatory Codes & Fines section for pertinent codes and fines that apply.

What to Look For

Sewage spills can be a very noticeable gushing of water from a manhole or a slow water leak that may take time to be noticed. Don’t dismiss unaccounted-for wet areas.

Look for:

• Drain backups inside the building.
• Wet ground and water leaking around manhole lids onto your street.
• Leaking water from cleanouts or outside drains.
• Unusual odorous wet areas: sidewalks, external walls, ground/landscape around a building.

Caution

Keep people and pets away from the affected area. Untreated sewage has high levels of disease-causing viruses and bacteria. Call your local health care agency listed on the back for more information.

If You See A sewage Spill Occurring, Notify Your City Sewer/Public Works Department or Public Sewer District IMMEDIATELY.

How a Sewer System Works

A property owner’s sewer pipes are called service laterals and are connected to larger local main and regional trunk lines. Service laterals run from the connection at the home to the connection with the public sewer (including the area under the street). These laterals are the responsibility of the property owner and must be maintained by the property owner. Many city agencies have adopted ordinances requiring maintenance of service laterals. Check with your city sewer/local public works department for more information.

Operation and maintenance of local and regional sewer lines are the responsibility of the city sewer/public works departments and public sewer districts.

How you can Prevent Sewage Spills

Never put grease down garbage disposals, drains, or toilets.

Perform periodic cleaning to eliminate grease, debris and roots in your service laterals.

Repair any structural problems in your sewer system and eliminate any rainwater infiltration/inflow leaks into your service laterals.

Sewage spills can cause damage to the environment. Help prevent them!

Preventing Grease Blockages

Dispose of grease properly! Do not put grease down drains. Scrape off plates, pans, etc., into grease cans for recycling. Homeowners may place small amounts into trash bins for disposal.

Restaurants and large buildings, such as commercial food establishments, may have grease traps or interceptors to keep grease out of sewer pipes.

To work correctly, a grease trap or interceptor must be:

• Sized correctly and designed to handle the expected amount of grease.
• Installed properly per local codes.
• Maintained properly, cleaned and serviced regularly.

Orange County Agency Responsibilities

• City Sewer/Public Works Departments—
   Responsible for protecting city property and streets, the local storm drain system, sewage collection system and other public areas.
• Public Sewer/Sanitation District—
   Responsible for collecting, treating, and disposing of wastewater.
• County of Orange Health Care Agency—
  Responsible for protecting public health by closing ocean/bay waters and may close food-service businesses if a spill poses a threat to public health.
• Regional Water Quality Control Boards—
   Responsible for protecting State waters.
• Orange County Stormwater Program—
  Responsible for preventing harmful pollutants from being discharged or washed by storm water runoff into the municipal storm drain system, creeks, bays and the ocean.

You Could Be Liable for Not Protecting the Environment

Local and state agencies have legal jurisdiction and enforcement authority to ensure that  sewage spills are remedied.

They may respond and assist with containment, relieving pipe blockage, and/or clean-up of the sewage spill, especially if the spill is flowing into storm stains or onto public property.

A property owner may be charged for costs incurred by these agencies responding to spills from private properties.
