Los Angeles-Glendale Water Reclamation Plant

LAG 12 ., holding tank
Los Angeles-Glendale Water Reclamation Plant (LAG) is strategically located to serve east San Fernando Valley communities that are both within and outside of the Los Angeles City limits. The plant’s highly treated wastewater meets and exceeds the water quality standards for recycle water for irrigation and industrial processes. This water reuse conserves over one billion gallons of potable water per year. The plant is highly automated and staff can control processes from the onsite control room or at remote locations.


In 1976 the Los Angeles-Glendale Water Reclamation Plant started operations as the first water reclamation plant in the City. The cities of Los Angeles and Glendale co-own the plant, and LA Sanitation operates and maintains it. Each city pays 50% of the costs and receives an equal share of the recycled water. The plant processes approximately 20 million gallons of wastewater per day.

In addition to its role as a leading producer of recycled water, LAG is another regionally strategic facility within the City's overall wastewater system. By processing flows in the eastern San Fernando Valley, the plant is able to provide critical hydraulic relief to the City's major sewers downstream, which serve other communities of the City.
