Pasadena's 2011 Water Integrated Resources Plan established a long term strategy to meet current and future water needs. This plan calls for developing alternative sources of water, for landscape irrigation, cooling and other non-potable uses, to meet Pasadena’s annual water demands. Pasadena Water and Power (PWP) plans to enhance the water supply reliability by non-potable water to the customers for landscape irrigation and industrial uses in the future.
The Pasadena Non-Potable Water Project is formerly known as the Recycled Water Project. The City of Pasadena has an agreement in place with the City of Glendale to provide up to 6,000 acre-feet of non-potable water annually to Pasadena from the Los Angeles-Glendale Water Reclamation plant. This water is tertiary treated through a three-step process imitating nature’s own cleaning processes. The Los Angeles-Glendale Water Reclamation plant processes 20 million gallons of non-potable water each day! The non-potable water produced is shared between the Los Angeles Department of Water and Power (LADWP) and the City of Glendale as cooling water by the Glendale Steam Power Plant and for irrigation at Griffith Park, in freeway landscaping, local cemeteries, at nearby golf courses and parks.
PWP is developing plans to construct a new distribution system to deliver non-potable water from the Los Angeles-Glendale Water Reclamation Plant (LAG) to the City of Pasadena. Phase 1 of the proposed Pasadena Non-Potable Water Project includes connections to four customers with large irrigation demands: Art Center College of Design, Brookside Golf Course, Rose Bowl Stadium, and Brookside Park. Phase 2 will include the City’s Glenarm Power Plant which will use the water for cooling and processes in place of potable water, saving millions of gallons of water annually.
The proposed Project could provide as a minimum 3,060 AF of non-potable water annually for citywide non-potable water use, meeting 9 percent of the City’s total water demand. One acre-foot of water is approximately 326,000 gallons.
The Public Draft Environmental Impact Report (EIR ) for the Pasadena Non-Potable Water Project is now available for public review on this webpage (see links below), and on the city's Department of Planning and Community Development website.

The following is the expected schedule for Pasadena Non-Potable Water Project, formerly known as the Recycled Water Project:
2012 - RECYCLED WATER PLANNING STUDY
2014 - NOTICE OF PREPARATION
2015 - ENVIRONMENTAL IMPACT REPORT
2015 - 2016 - COMPLETE DESIGN, OBTAIN FUNDING AND PERMITS
2016 - 2018 - CONSTRUCTION OF PHASE 1
Recycled water is wastewater that has been cleaned to remove impurities. Colorless and odorless, the recycled water from LAG is tertiary treated and disinfected by a three-stage treatment and is allowable for all human contact except consumption. Recycled water is typically used for non-potable (not for drinking) purposes such as landscape irrigation, recreational lakes, decorative fountains, in industrial processes, commercial car washes, concrete mixing, construction dust control, soil compaction, street and sidewalk cleaning, flushing sanitary sewers, cooling towers and air conditioning.
As our community grows, the demand for potable water increases as Pasadena’s dependency on imported water. Recycled water provides a dependable, locally-controlled water supply for non-potable uses, such as landscape irrigation, cooling, and dust control. Using recycled water is making use of a valuable resource that would otherwise be wasted and has many environmental benefits such as:
Like Pasadena, many other organizations see the benefit of using precious water resources more than once. Below you will find a list of a few of the local organizations providing recycled water:
Burbank Water and Power City of Glendale City of San Diego Irvine Ranch Water District Long Beach Water Department Los Angeles Department of Water and Power Orange County Water District
The recycled water that is available to the City of Pasadena is categorized as “Disinfected Tertiary Recycled Water.” This water has undergone treatment for a wide range of contaminates and is filtered and disinfected prior to the water being distributed.
The City of Pasadena plans to use recycled water for landscape irrigation of schools, parks, golf courses, freeway medians, hospitals, stadiums, cemeteries, and libraries. Recycled water will also be used for industrials cooling by the largest water customers such as Art Center College of Design, Huntington Memorial Hospital, Glenarm Power Plant, Caltech, Pasadena City College, and JPL.
The State of California encourages the use of high-quality recycled water. More information about recycled water use rules and regulations can be found at:
