Sewer Information

General Information

The city maintains over 1.6 million lineal feet or 308 miles of sewer pipeline. Maintenance includes annual cleaning of sewer lines and periodic videotaping to search for trouble spots. Keeping the sewer system clean helps limit potential sewage overflows that could threaten our health and water quality.

Sewer Lateral Connections

A sewer line from a private property is connected to the public sewer main on the street by means of a sewer lateral. Each property is connected to the sewer main with a separate sewer lateral. The sewer lateral is the section of the sewer pipe line running roughly perpendicular from the private property to the sewer main on the street

The construction and maintenance of the sewer lateral is the responsibility of the private property owner.

New Connection

Construction of a new sewer connection requires a Plumbing Permit from the Building Department and an Encroachment Permit from the Public Works Department.

The fees include:

  • City Sewer Connection Fee
  • County Sanitation Fee
  • Sewer Frontage Fee
  • Assessment District Fee
  • Plumbing Permit Fee
  • Encroachment Permit Fee

The property owner is advised to visit the Public Works Department and the Building Department for further information to help determine the feasibility of the project.

Repair of Existing Sewer Lateral

A Plumbing Permit and an Encroachment Permit are required for repair of a sewer lateral between the property line and the sewer main in the street. This includes works in the sidewalk area, in the parkway area, and on the street pavement. A licensed contractor should be hired to perform the work. The contractor should apply for the permits on behalf of the property owner.

For Property Owners in County Unincorporated Islands

To connect a sewer lateral to a City of Orange sewer main line, property owners in County Unincorporated areas are required to enter a Sewer Agreement with the City, in addition to paying all of the above fees.

Connection of Sewer Lateral to County Trunk Line

For certain streets, the sewer mains are components of Orange County Sanitation District trunk lines. The City of Orange does not have jurisdiction for these lines. Once the City's Public Works Department has determined that such a situation exists, the property owner will be further instructed to process additional applications with the Orange County Sanitation District office.
