Water System Overview
For nearly a century, the City of Bend has been providing high-quality drinking water to residents, businesses, and visitors. From source to meter, the City works to protect our supplies, treat and clean our water, and maintain a network of pipes, storage reservoirs, and other facilities to deliver safe, reliable drinking water to customers’ taps. Learn more about our water with the Virtual Tour.
Tour Stops

Tour Stop 1: Surface Water Supply
Since 1926, the Bend Municipal Watershed has been the City’s primary water source. Surface water from Prowell Springs (image below) flows by gravity down Bridge Creek through the mountains and valleys, making its way to our Bridge Creek Intake Facility. We work closely with the U.S. Forest Service to ensure this high-quality surface water source stays protected.
At the intake facility (image below), the Water Services Department continuously monitors water quality, temperature, and levels to protect and better understand our watershed. From the intake, surface water travels by gravity through a 10-mile pipe under Skyliner Road to the Outback Water Filtration Facility (Stop 2).

Tour Stop 2: Outback Water Filtration Facility
The City manages a robust treatment system to provide clean, safe drinking water and protect against future water quality risks. The Outback Water Filtration Facility is where pathogens and turbidity (sediment suspended in water) are filtered from our drinking water. The membrane filtration system filters up to 11.8 million gallons per day and uses multiple steps to remove particles too small for the naked eye to see. We also add a small amount of chlorine to deactivate viruses and bacteria while keeping our network of storage tanks and pipelines clean.

Looking forward, the City is planning to install pre-treatment at the Water Filtration Facility to improve system resilience to potential water quality events in the watershed like the 1979 Bridge Creek Fire.

Tour Stop 3: Groundwater Supply
The City has a second high-quality water source that provides supply resilience for our growing high-desert community. During the summer months, we pump from deep groundwater wells connected to the Deschutes Regional Aquifer to supplement our water supply and meet peak demands.
The City maintains eight groundwater facilities with 20 active wells and large pumps to bring water to the surface. The groundwater is naturally filtered by layers of soil, volcanic rock, sand, and gravel and then small amounts of chlorine disinfection are added when the water is pumped to make it safe to drink.

Powerful pumps pull groundwater from deep wells into pipes and reservoirs throughout the City.

Tour Stop 4: Pipelines and Water Storage
The City maintains a network of pipelines and storage reservoirs to reliably deliver clean and safe water to homes, schools, businesses, and fire hydrants throughout Bend. Our system includes 15 storage reservoirs, 6 active booster pump stations, and about 440 miles of water pipes.
The storage reservoirs are on hills, so gravity helps produce consistent water pressure throughout the system. Combined, our reservoirs store up to 30 million gallons of water to serve the daily needs of the community and provide backup in case of fires or other emergencies.

Frequently Asked Questions
Have questions about Bend’s drinking water? Check out these FAQs:
Bend’s water comes from two high-quality sources: surface water from the Bend Municipal Watershed in the Deschutes National Forest and groundwater from the Deschutes Regional Aquifer. The Upper Deschutes Basin absorbs snowmelt and rainfall, recharging the aquifer annually.
The City ensures our water meets the highest standards through rigorous protection, treatment, and testing. Each year, we publish a Water Quality Report with detailed testing results. You can also tour our Water Filtration Facility to see our treatment process in action.
The City regularly plans to maintain the reliability of our drinking water system. In 2021, we completed an Integrated Water System Master Plan, combining conservation, operations, and economic analyses to plan for the next 20 years.
Yes, based on recent analyses, our current water supplies and rights are sufficient to meet projected demands through 2040. The WaterWise Program and efficient water use will continue to be key in maintaining a reliable supply.
Bend benefits from two high-quality water sources, providing enhanced resilience. Our surface and groundwater supplies, combined with a commitment to conservation and efficiency, ensure we can meet needs during all water years, including droughts.
The City offers various guides, tools, and free resources to help improve water efficiency. The WaterSmart tool, for example, allows customers to track and manage their water use effectively.
