Building Local Water Supplies
LADWP is committed to providing a reliable, resilient and sustainable water supply for Los Angeles. Through local water initiatives like Operation NEXT, recycled water, stormwater capture, groundwater remediation and water conservation, LADWP is reducing dependence on imported purchased water and ensuring that our future water supply is strong for generations to come.
When it comes to saving water, LADWP customers are heroes. Angelenos have long embraced water-saving ethics, and water conservation is at the core of multiple strategies to ensure a sustainable water supply. Water use has dropped by over 30% in the past 15 years as our customers have diligently maintained their water-efficient habits.
Operation NEXT is an innovative water supply initiative being developed by LADWP in partnership with LA Sanitation and Environment (LASAN) that aims to improve the overall water supply resiliency and reliability for Los Angeles. The goal of Operation NEXT is to maximize purified recycled water from the Hyperion Water Reclamation Plant in Playa del Rey, using advanced treatment processes, to create a new sustainable water resource that will diversify the supply for L.A. and the region.
Recycled Water for Residents
To help save drinking water, LADWP reopened three recycled water fill stations where customers could fill up to 300 gallons of recycled water for irrigation during every visit. From late July through December 2022, the stations garnered over 1,000 visits from customers who filled jugs and buckets with more than 141,000 gallons of recycled water. The program offset precious drinking water and helped make recycled water more accessible to customers.
Expanding our capacity for capturing stormwater runoff is a key strategy to ensure our city remains water strong. Capturing and managing stormwater is a reliable and sustainable way to replenish local groundwater aquifers while reducing urban flooding. Stormwater capture also improves the quality of water that flows downstream to rivers, lakes, and the ocean. With over 70 new projects forecasted over the next 15 years, LADWP and its partners, such as the Los Angeles Department of Public Works and Los Angeles County Flood Control District (LACFCD), will double the city’s stormwater capture capacity. Many of these projects will happen at our neighborhood parks, and LADWP will be upgrading park amenities along the way. Our stormwater capture goal is to reach 48.9 billion gallons (150,000 acre-feet) of annual stormwater capture capacity by 2035. For reference, an acre-foot of water is roughly equivalent to one foot of water covering a football field.
The San Fernando Groundwater Basin (SFB) is a critical local water resource but has been limited due to historical contamination affecting nearly 50% of LADWP’s groundwater wells. LADWP continues expanding remediation systems to remove contamination from the SFB. During dry periods, when purchased imported water is less available, the SFB has provided an average of 12% of our water supply, and up to 23% during extended dry periods. Resolving contamination problems and restoring the beneficial use of the SFB are essential to protecting public health and the environment, and to recovering LADWP’s historical groundwater supply as a valuable local water resource. Based on an extensive groundwater remedial investigation and improvement study, LADWP has installed 26 monitoring wells. These new wells, along with a network of 70 existing wells, provide data to evaluate groundwater quality in the northern portion of the SFB, which includes the city’s most productive wellfields. LADWP’s current groundwater remediation efforts are focused on three major response actions: The North Hollywood West, North Hollywood Central, and Tujunga Wellfields. Additional groundwater evaluations in the Southern San Fernando Basin Wellfields are also underway.
One critical resource is the Los Angeles Aqueduct, which runs 233 miles north of Los Angeles carrying fresh runoff from the Eastern Sierra to L.A. Completed in 1913, the L.A. Aqueduct was the largest water infrastructure project in the world at the time. Now, more than a century later, the L.A. Aqueduct is still a foundational purveyor of water for Los Angeles. Today, LADWP maintains stewardship of nearly 315,000 acres of land throughout Inyo and Mono counties.
LADWP has an increasing block rate structure with four tiers for residential customers and two tiers for all other customer classes. As of April 15, 2016, this new rate structure went into effect for all LADWP customers. Find out which rates apply to you.
