Environmental Services

Have you ever wondered what happens to the water--and other stuff--you pour down the drain or flush down the toilet?

All that used water and other stuff is called wastewater. And in Petaluma, wastewater travels from the plumbing in your home or office into the city's sewer pipes until it reaches the Ellis Creek water recycling plant. Once there, the solids and liquids get separated.  The solids get collected and turned into biofuel. The liquid goes through treatment and filtering until it's clean enough to be released into local waterways or used on area farms and sports fields.

The Environmental Services team makes sure the system doesn't get overwhelmed. They work with businesses that produce a lot of wastewater, looking for ways to clean some of the water before it gets to Ellis Creek. They also manage the City's water conservation, pollution prevention, and storm water programs.
