IRWD has a long history of planning for the future water needs of our community, and we're continuing this tradition with the Syphon Reservoir Improvement Project.

This five-year undertaking begins in July to increase recycled water storage capacity at one of IRWD's four recycled water reservoirs.

By increasing recycled water storage capacity locally, this project will:
✔️ Prepare us for the future by storing more drought-proof water.
✔️ Enable IRWD to use nearly 100% of the recycled water it produces.
✔️ Keep our community green and beautiful.
✔️ Provide water to fight wildfires throughout the region.
✔️ Save customers $990 million to preserve low rates.

Learn more about the Syphon Reservoir Improvement Project at syphonreservoirproject.com.

Looking for an early burst of color for your garden this spring? Check out our landscape expert Juan's pick for this May: the California bush sunflower.

Known for its bright yellow blooms that appear from winter into spring, it attracts butterflies and bees and offers cheerful stems for flower arrangements. As the season progresses, the plant’s seeds become an important food source for birds. The plant’s dense, fibrous root system also makes it useful for erosion control on slopes and disturbed soils.
