Speeding up Mother Nature's work
Roseville safely cleans used water and returns it to the environment every day. It’s a behind-the-scenes system that protects public health, keeps our creeks and rivers clean, and supports a growing region.
Here’s how it comes together:
- We operate two wastewater treatment plants that can treat up to 30 million gallons per day
- We maintain hundreds of miles of sewer pipelines across the city
- We reuse more than 1 billion gallons of water each year for irrigation and other beneficial uses
The result is simple: reliable service, protected waterways, and smart use of every drop, all while keeping costs as efficient as possible.
How wastewater is cleaned and returned to the environment
1. Your home or business: Water goes down drains from sinks, showers, toilets, and washing machines.
2. Collection system: Underground pipes carry wastewater to treatment plants.
3. Treatment: Wastewater is cleaned to remove solids, bacteria, and pollutants. Wastewater is treated 24/7 to protect public health and the environment.
4. Return to environment: Clean water is safely returned or reused.

If you experience sewer backup issues, contact your wastewater collections staff at (916) 774-5750 to evaluate the next step.
This service is available, paid through the monthly rates for wastewater services. We are available 24 hours a day, seven days a week.
As a service, a crew will check to see if the backup is in the city’s main or service. If it is, we will clear the blockage. However, if the blockage is in the lateral serving the residence or business, it is the resident's/business owner’s responsibility to clear any blockage in their lateral line, which connects their property to the City’s.
To better assist us in identifying the source of odors, please use the online form. We will evaluate the cause of the odor and take corrective actions whenever possible.
Recycled water helps keep Roseville green while protecting our drinking water supply. Each year, we deliver nearly 1.25 billion gallons through our purple pipe system to parks, medians, and golf courses—providing a safe, reliable source for irrigation.
