How we build and repair sewers

Most Los Angeles sewers are in good condition. Many of the sewers were built in the early part of the 20th century. As the sewer system ages, pipes deteriorate from years of scouring and corrosion. Additionally, explosive population growth in many parts of the City has caused some sewers to run at or near capacity.

The Department of Public Works uses both closed circuit television and manual inspections to check on the condition of its sewers. Some sewers can be repaired and others need to be replaced as part of the City’s Wastewater Program.

Three construction techniques are typically used to build sewers in Los Angeles – trenching, microtunneling, and large bore tunneling. The Department of Public Works analyzes each proposed sewer to determine which method is best suited for the work.
