Reclaimed / Recycled Water

Recycled water saves precious potable water supplies that would otherwise need to be used for the irrigation of city parks, street sweeping, and industrial uses. Long Beach also uses recycled water for a variety of purposes.

Long Beach Water Reclamation Plant, is located on the east side of the City. The plant is owned and operated by the Sanitation Districts of Los Angeles County. LBWRP treats approximately 18 million gallons per day of wastewater to stringent regulatory standards for disinfected tertiary recycled (or reclaimed) water.

Once it meets certain levels of treatment, tertiary recycled water can be used to:

  1. Irrigate parks, golf courses, cemeteries and athletic fields
  2. Recharge our groundwater basin
  3. Street sweep


Long Beach Water is committed to developing alternative sources of water versus using precious, imported water to meet the annual water demands our customer, particularly those using potable water primarily for industrial and irrigation operations.

In an effort to reduce our need to purchase increasingly expensive imported potable water and to further diversify the City’s water supply reliability portfolio, Long Beach Water is involved in a large, recycled water system expansion.

The Recycled Water System Expansion Program is primarily intended to connect the recycled water system to new customers, as well as increase the reliability of the distribution system through the completion of looped transmission corridors. The primary elements of the program include the construction of recycled water pipeline, new pump stations, augmentation of water system storage, and the completion of new service connections.

A descriptive map of the recycled water system can be seen here:

When complete, the expansion program will increase citywide recycled water consumption to approximately 9,000 acre-feet annually, eventually meeting 15 percent of the city’s total water demand.  The city’s recycled water system will stretch from the east side of the City to the west, including a possible connection to Terminal Island. One acre-foot of water is approximately 326,000 gallons.

Highlights of this program include connections to customers with large irrigation operations like California State University Long Beach and the Long Beach Unified School District, in addition to several large parks, golf courses, cemeteries and athletic fields.

The City’s street sweepers also fulfill some of their water demands using recycled water in place of potable water.  This has the potential to additionally save millions of gallons of water annually.

The recycled water that is distributed in the City of Long Beach is categorized as “disinfected tertiary recycled water.”  This water has undergone treatment for a wide range of contaminants, including nutrients such as nitrate and phosphate, and is filtered and disinfected prior to the water being distributed.
