Delivering nearly 1.25 billion gallons of recycled water annually

Recycled water keeps city landscapes looking wonderful and lush. 

This is a clean and safe source of irrigation water conveyed through purple pipes in the ground. We use this resource in parks, medians and golf courses in Roseville. While it's not suited for drinking, it's perfect for irrigating grass, plants and trees.

Best of all, its great for the environment because it lets us keep the grass and plants green without having to use drinking water. We produce recycled water at both of the City's wastewater treatment facilities and deliver roughly 1.25 billion gallons of recycled water to more than 200 sites.

Recycled water for development

Although potable water permits are available, customers can still take advantage of recycled water for construction or landscape needs. Contractors can apply for recycled water hydrant permits for dust control, soil conditioning and street sweeping. Landscape contractors can purchase recycled water to hand irrigate landscapes and to maintain the health and viability of high-valued and beneficial trees.

What does the City of Roseville do with recycled water?
The City pumps recycled water through a system of purple pipes that are completely separate from the potable (drinking water) pipes. The City pumps the recycled water to customers like golf courses and parks, where they use it to irrigate their turf and shrubs.

Currently parks and golf courses are the main users of recycled water in Roseville. Environmental Utilities also provides recycled water to the Roseville Energy Park for their cooling towers and for construction use, including dust control, soil processing, and street sweeping.

Why does the City of Roseville recycle water?
The City recycles water to create a more reliable water supply in our growing community. Not only does the use of recycled water offset the use of potable water, recycled water is drought proof. That is to say, during times of drought, the recycled water supply is unaffected.
