Testing before the tap

The new Improved Corrosion Control Treatment facilities continue to work as planned: they’re gradually changing the Bull Run water’s chemistry to make it less corrosive to lead and other metals found in some home and building plumbing. The Portland Water Bureau tests how corrosive our water is by replicating the conditions of high-risk homes in our lab. We use those test results to inform operations at the new facilities. We expect our water to become even less corrosive as we continue to increase the pH to 8.5 and alkalinity to 25mg/L.

Watch a video about the testing process.

Aiming for a sustainable filtration design

The Filtration project team is taking a holistic approach to sustainable design. The team plans to use low-carbon concrete, pursue LEED Gold and net-zero energy use for the Administration Building, follow the City’s Green Building Policy, and pursue Envision certification for the facility. The Envision framework assesses sustainability, resilience, and equity in civil infrastructure to better protect the environment, enhance human health and well-being, and bolster economic prosperity. We expect the filtration facility to be the first Envision-certified City project.

Project team shoutout: Michelle Cheek, Bull Run Treatment Program Deputy Program Director

About the Bull Run Treatment Projects

To comply with federal Safe Drinking Water Act regulations, the Portland Water Bureau is planning a water filtration facility, new pipelines, and an improved corrosion control treatment facility. The Bull Run Treatment Projects will provide consistent, high-quality drinking water that meets today’s water quality standards, helps address aging infrastructure concerns and future risks and regulations, and improves system resilience to help keep our water safe and abundant for generations to come.
