As Los Angeles faces growing challenges with its imported water supply, developing sustainable, local water resources is more critical than ever. Water recycling offers a proven, reliable, and environmentally responsible solution to bolster the City's water supply.
Water recycling involves treating wastewater to create a safe and valuable resource for diverse uses, including irrigation, industrial processes, groundwater replenishment, and seawater intrusion prevention. This innovative approach helps reduce reliance on imported water, conserve precious drinking water supplies, and supports a more sustainable water future for all Angelenos.
Groundwater Replenishment: Leading the Way Forward
The cornerstone of LADWP's recycled water strategy is the Los Angeles Groundwater Replenishment Project (LAGWR). LADWP will utilize advanced water purification technology to create purified recycled water that can safely recharge local aquifers. This ensures a drought-resilient and environmentally sound supply of water for generations to come.

Pure Water Los Angeles: A Bold Step Toward Sustainability
Pure Water Los Angeles (PWLA) is an innovative program that transforms the way Los Angeles manages its water resources. By using advanced purification technologies, the program recycles wastewater to create a clean, safe, and drought-resilient water supply. This initiative combines multiple strategies including groundwater replenishment with direct potable reuse, where purified water will be added directly to the city's drinking water system. These efforts reduce reliance on imported water, helping Los Angeles become more self-sufficient and sustainable. PWLA is key to building a water-secure future while protecting the environment. By reusing water responsibly and efficiently, this program supports a thriving city even during periods of drought

Direct Potable Reuse: The Cutting Edge in Water Treatment Technology
LADWP has launched a Direct Potable Reuse Demonstration Project, which will showcase the safety, reliability, and efficiency of introducing purified water into the city's drinking water supply. This project highlights the advanced technologies used to exceed regulatory standards for water quality, while also building public trust and contributing to the development of statewide guidelines for direct potable reuse. It is a significant step forward in proving the viability of this sustainable water source.
Established Purple Pipe Network: Continuing our 40 Year History of Recycled Water
Since 1982, LADWP has been using recycled water to support irrigation in landmark locations such as Griffith Park, Mount Sinai, and Forest Lawn Memorial Parks. Today, the city's purple pipe network continues to deliver recycled water for irrigation and industrial purposes, playing a vital role in reducing potable water demand across Los Angeles.
Securing a Sustainable Future
Through innovative programs like groundwater replenishment and established systems like the purple pipe network, LADWP is working tirelessly to conserve drinking water, protect against drought, and ensure a reliable water supply for generations. Together, these efforts represent a bold commitment to securing Los Angeles' water future.
With these initiatives, LADWP is not just addressing today's water challenges but building a resilient and sustainable future. Every drop counts, and together, we can create a water-secure Los Angeles.
