UPDATE: West Basin Municipal Water District Recycled Water Use
The recycled water that the West Basin Municipal Water District cleans and provides to its customers continues to be safe for its permitted, non-potable uses. West Basin is taking proactive measure to ensure this.
West Basin is working to assure continued delivery of non-potable, Title 22 recycled water given the elevated suspended solids and turbidity levels in the water West Basin receives from the Hyperion Water Reclamation Plant (influent). West Basin is taking active measures to ensure that the Title 22 recycled water, commonly used for irrigation purposes, continues to be safe for its permitted, non-potable uses.
As a result of recent influent quality, turbidity levels of West Basin’s Title 22 recycled water have exceeded the lower permit limits at times. Increased levels of turbidity can result in a slightly cloudy water.
To help mitigate the turbid influent water, West Basin is taking the following measures. We are:
- Blending Title 22 recycled water with drinking water (approximately 30%);
- Increasing its coagulation treatment to remove solid particles from the influent; and
- Increasing chlorine dosage at its Edward C. Little Water Recycling Facility in El Segundo and at locations within its distribution system to minimize odor.
In addition, West Basin is:
- Increasing the frequency of its recycled water sampling, and providing the regulatory agencies with daily updates to ensure the Title 22 recycled water continues to be suitable for its permitted use.
For background, turbidity is a metric that indicates the clarity of the water. Total Suspended Solids (TSS) is a measure of the suspended particles in the water that reduce its clarity. It should be noted that the coagulation that occurs as part of the treatment process can also make the water more turbid, creating a noticeable tint to the water as well as contributing to odor.
West Basin continues to work with its recycled water customers and communities to provide updates and answer questions. Recycled water use benefits the entire community, especially during periods of drought like we are experiencing now. We thank all of our customers for their sustainability.

West Basin Recycled Water Meets Health and Environmental Requirements After L.A. Hyperion Incident
The West Basin Municipal Water District assures its recycled water customers and community that the water it cleans and produces for irrigation purposes (also known as Title 22 or Disinfected Tertiary water) meets all regulated health and environmental requirements.
In light of current circumstances at the Hyperion Water Reclamation Plant, the source of West Basin’s recycled water influent, West Basin has taken the extra step of blending its recycled water with drinking water to reduce turbidity (e.g., cloudiness) and odor that may temporarily occur as the City of Los Angeles works to fully restore the Hyperion plant.
Recycled water use benefits the entire community, especially during periods of drought. We thank all of our customers for their sustainability.
