Private Sewer Lateral Policy

Private Sewer Lateral Policy LACSD is committed to reducing inflow and infiltration of stormwater into the sewer system. Excessive stormwater in the sewer can cause wastewater overflows with the potential to damage public health, property and the environment. LACSD conducts methodical repair and maintenance of its sewer mains to reduce these risks but private sewer laterals are an unknown contributor to stormwater inflow due to the unidentified condition of these pipes.

A private sewer lateral is the pipeline that connects a home’s wastewater flows to the District’s sewer collection pipeline. The connection to the sewer main is usually located in the street or near the property line. Private sewer laterals are owned and maintained by the property owner, including any part that extends into the street or public right of way.

Poorly operating or failing private sewer laterals allow Inflow & Infiltration (I&I) of stormwater which can lead to hydrological overloading of the sewer system during rain events contributing to sanitary sewer overflows (SSOs). Additionally, the lack of the pipe’s integrity may promote ex-filtration which contaminates private and public property, resulting in a public health concern. Additionally, exfiltration and SSOs are a threat to the local receiving waters that they flow to.

In 2017, LACSD’s Board of Directors adopted the Private Sewer Lateral Compliance Policy, Ordinance No. 81 . The purpose of the policy is to reduce I&I, exfiltration, and SSOs to and from privately owned sewer laterals. This policy requires inspections of private sewer laterals under certain conditions by a licensed plumber via Closed Circuit Television Video (CCTV). The full text of the Private Sewer Lateral Policy can be read here.

An inspection of a private sewer lateral is required under the following conditions:

  • When the sewer lateral is repaired or replaced
  • When a property is remodeled, and plumbing fixtures are changed
  • When two or more sewer overflows occur at a property within a two-year period
  • When a property changes from residential to commercial use
  • Whenever the District determines from its operation, maintenance or inspection of sewer facilities that a defect may be present
While not required, it is highly recommended for new home buyers to conduct an inspection of the private sewer lateral for their own protection prior to closing escrow.
