How Irvine stays so inexperienced

Landscaping irrigated with recycled water.

Recycled water irrigates approximately 85 percent of public and commercial landscaping in the Irvine Ranch Water District and provides a reliable and sustainable resource.

With communities across the country, especially in the arid Southwest, struggling to meet their water needs, the Irvine Ranch Water District has long been a national leader in wastewater recycling.

“If Irvine looks greener and more lush than other communities, it is because of our recycled water program,” said Paul Cook, general manager of the Irvine Ranch Water District. “While others are cutting back, Irvine is able to maintain its tree-lined streets, green averages, and lush public spaces – – because every gallon of recycled water used there saves one gallon of drinking water. “

Since 1967, the IRWD has lived by the motto “Water is too valuable to be used only once.” That year, with significant support from the Irvine Company, the water district opened the Michelson water recycling facility and began delivering recycled water for irrigation throughout District.

This program of water recycling and distribution is made possible by hundreds of kilometers of purple pipes, a special system – separated and separated from the drinking water supply – – transports the transported recycled water from the treatment plant to irrigation sites throughout the district.

When Irvine was in the earliest stages of master planning, the IRWD board of directors had the foresight to include this purple whistle system – A color that Irvine Ranch chose and that is now an industry standard.

With careful planning, it is possible to distribute recycled water throughout the community without the hassle and cost of digging roads to install new pipelines.

Recycled water began flowing to customers in 1967. By 1990, 14 percent of all water used in the Irvine Ranch Water District was recycled. And today, More than 20 million gallons of recycled water a day flow through more than 500 miles of purple pipes.

Recycled water pipesRecycled water is supplied through purple pipes, a distribution system that is completely separate from the drinking water infrastructure.

The Irvine Ranch Water District recycles 9 billion gallons of water each year, more than any other city in America.  This is how it all happens: You can find more information at www.irwd.com/services/recycled-water.
