Ellis Creek Water Recycling Facility

Water Recycling Facility

The Ellis Creek Water Recycling Facility (ECWRF) is a state-of-the-art wastewater treatment plant owned and operated by the City of Petaluma. Opened in 2009, ECWRF plays a vital role in ensuring that all wastewater from Petaluma and Penngrove is treated, recycled, and reused to benefit the community and environment.

At ECWRF, wastewater undergoes advanced treatment, filtration, and ultraviolet (UV) light disinfection to ensure the production of high-quality recycled water. The result is clean, safe recycled water that meets strict regulatory and public safety standards. This recycled water is then utilized for landscape irrigation, reducing the demand for potable water.

Where is Recycled Water Used?

The recycled water produced at ECWRF serves a variety of important purposes both on-site and across the city:

• On-Site Uses:
  • Landscape irrigation
  • Fire protection
  • Plant process water
  • Toilet flushing
• Citywide Uses:
  • Irrigation of parks, schools, and public and commercial landscapes
  • Golf course irrigation
  • Vineyard and agricultural land irrigation

By using recycled water for these applications, Petaluma supports agriculture and conserves its drinking water supply, ensuring more sustainable water management for the community.

Polishing Wetlands: Nature’s Filter

ECWRF features 31 acres of polishing wetlands, a key part of the natural wastewater treatment process. These wetlands help remove excess nutrients and metals from the treated water, acting as nature’s filter before the water is either reused or released.

The wetlands aren’t just functional—they are also a thriving habitat for local wildlife. More than 2.5 miles of public trails wind through the wetlands, providing access to a larger 7-mile trail network that connects to 230 acres of wetlands. Visitors can explore these trails, enjoy bird watching, and observe the diverse range of wildlife that calls the area home.

A Haven for Wildlife

The polishing wetlands at ECWRF support a rich diversity of wildlife, making it a natural sanctuary for many species, including:

• Birds: Pelicans, egrets, herons, sandpipers, Red-tailed hawks
• Reptiles: Western pond turtles
• Songbirds: Marsh wrens

These wetlands not only enhance water quality but also provide a valuable habitat, enriching the ecosystem and supporting local biodiversity.
