Upcoming Water System Maintenance and Fire Hydrant Flow Testing:

In an effort to preserve water quality and system reliability, the Public Works Department’s Water Division has initiated a flushing program in the central region of the City.  The City is taking a number of measures to minimize the potential impact to water customers. Flushing operations will be conducted at night when water demand and use is low. Flushing and operational activities will normally start at 10:00 PM each night, and take approximately five hours to complete.  Please be informed that flushing operations is the industry standard for enhancing water quality and clarity.  It typically causes temporary water discoloration in a localized area, however, in a manner that is within the control of maintenance staff. In the event that water from your faucets is discolored, we recommend that you flush your system by running faucets for a few minutes. The City does not recommend using discolored water. We do recommend that you minimize use of water, during these times, if possible. Water quality is our top priority, as we continue to make adjustment to the water system to maintain its integrity. Should you have any questions or concerns please contact the Public Works Department at 323-563-5790.

Lead and Copper Inventory

The US EPA has a Lead and Copper Rule that aims to reduce exposure to lead and copper from drinking water service lines constructed on private property. This requires the City to conduct an inventory of all the private plumbing systems to document the material of the underground water pipeline connecting to the City’s water meter, as Lead, Non-lead (copper, plastic, etc.) or Galvanized. Note that this is the underground pipeline located between the City’s water meter and your building facility/house. The City contracted with Golden Meters Service Inc. (GMS) to conduct and submit the material inventory to the State Water Resource Control Board. For more information, please click on the link.(PDF, 603KB)
