Sewer Projects

LA Sanitation, in conjunction with the Department of Public Works, manages over 100 sewer design and construction projects throughout Los Angeles every year. These improvements are being built so that we can continue to provide you, our customers, with reliable service. 
Sometimes this work goes unnoticed because it often takes place underground. But occasionally, work must be done in streets or alleys near homes or businesses. The City takes care to reduce noise, dust, traffic and any other potential construction nuisance to a minimum. We also meet with and mail updates to neighbors before and during construction to get input and give progress reports.

Below is information on some of our current construction projects.


  • Construction will generally take place Monday to Friday from 7 am to 4 pm. Exceptions are noted below for individual projects.
  • Weather or other circumstances could shift the work schedule.
  • Neighbors will be informed as conditions warrant. In order to minimize disruption in the streets, most of the construction work at each location will be completed in about 5-10 business days.
  • Trucks and other equipment will be used during construction, and you may see open trenches, pipes, piles of excavated dirt, and debris.
  • Dust control will be provided in all project areas.
  • Enclosures or other barriers will be used in construction areas wherever necessary for public safety.
  • Flaggers will be used where traffic is impacted. Traffic will be restored to normal when construction has been completed at the end of each workday.
  • Trash pickup, deliveries, access to businesses, and access to residential driveways will be maintained.
  • Parking may be temporarily restricted in some areas, and signs will be posted in advance telling you where and when.
  • You will be notified 24-48 hours in advance whenever sewer services may be temporarily interrupted.

East West Valley Intercepter Sewer

East West Valley Intercepter Sewer  

East West Valley Interceptor Sewer Project will increase the production and use of recycled water in the City of Los Angeles to help address concerns about the long-term reliability of imported water. The proposed project would divert and convey wastewater from the eastern portions of the San Fernando Valley to the the Donald C. Tillman Water Reclamation Plant (DCTWRP) in Van Nuys, where it would be used to generate recycled water that would be distributed through the existing recycled water distribution system that extends from DCTWRP.

The project will convey additional flows via a 6-mile, 24-inch to 42-inch diameter force main sewer from the North Hollywood, Van Nuys/Sylmar, and Pacoima primary sewer basins to DCTWRP. The alignment will travel along Victory Boulevard between Vineland Avenue and Haskell Avenue, diverting up to 21 million gallons per day (MGD) peak dry weather flow by 2090.
