  • Sewer laterals should be owned and maintained by the property owner

Liability insurance providers do not want cities to be responsible for sewer laterals.

Nephi learned that to be the case from the insurance provider.

As a result, the Nephi City council directed the city council attorney, Denton Hatch, to prepare ordinances that will assign responsibility for water and sewer lateral to the owners of structures that are connected to the water and sewer systems.

Sewer laterals can deteriorate due to poor installation, inferior or defective materials, and/or poor maintenance causing them to develop fissures, cracks or other openings. These openings are most likely to occur at pipe joints. In time, tree roots seeking moisture will penetrate these openings. Once in the sewer lateral, the roots continue to grow. These roots reduce the effective diameter of the sewer lateral and sometimes completely block the flow of sewage.

In addition, the line may be blocked by sewage from the home, independently of tree roots.

"Our liability insurance providers think the sewer lateral should be owned and maintained by the property owner," said Randy McKnight, city administrator.

This includes both the portion of the sewer lateral that is on private property, and the portion that is within the street or public right-of-way.

"A lateral sewer line is the smaller line that is at a 90 degree angle from the Main sewer line," said McKnight.

He said it is the private sewer line, that travels from the house to the public (or mainline) sewer.The sewer lateral is the line that sends liquid waste from a residence or business to the city sewer main.The public sewer system provides for the conveyance of sewage from homes and businesses to the city sewer lagoons. 

At the request of the insurance provider, the city is revisiting its existing policy.

"They suggested that the city not accept responsibility for construction of sewer laterals," he said. "We have the ability to clean the main lines but not the laterals."

The owner and contractor should be responsible for building sewer laterals according to city code. The same holds true for a single dwelling to a subdivision.

This is a problem shared by cities across the country and around the world. Many cities have the policy of placing the responsibility for the construction, maintenance and repair of sewer laterals entirely on the property owner. For these cities, the property owner pays the full cost of sewer lateral replacement even if the lateral is crushed or misaligned by parkway trees.

The privilege is granted to the house owner to connect his house with the publicly owned street sewer main line and the duty to keep clean the privately owned sewer lateral rests upon the owner of such house-connecting sewer, not upon the city.

The rationale behind a property owner owning and maintaining the sewer lateral serving his/her property is as follows: a sewer lateral does not benefit the public as it serves a single lot.

Because a portion of the sewer lateral is in the public street does not mean that it is public property. The property owner has the legal right to construct and maintain a sewer lateral between his/her private property and the public sewer, subject to the provisions of the municipal code.

Cleanouts can be installed at the property line.

There is also an issue of liability if any repair or replacement of a private sewer lateral is performed by city crews. The city may be liable for any future problems with that lateral. These future problems may include health hazards or significant property damage.

Property owners would be responsible for their own lateral to the sewer main without the possibility of reimbursement. Additionally, this policy removes the city's liability for sewer lateral blockages or breaks. It allows the City to focus its attention on the public sewer mains and sewer lagoons, which benefits all residents.

Hatch was directed, by vote of the council, to prepare ordinances that will assign responsibility for water and sewer laterals to the owners of structures that are connected to the water and sewer systems.

Culinary water mains are included in the direction.
