The City is now repairing a major, 100-year old sewer that is located in Los Angeles and Inglewood. The 60 by 73-inch, brick-lined sewer, built in 1904, is deteriorating and needs to be rehabilitated to make it reliable so it maintains structural integrity, has adequate capacity, and does not release spills or odors.
