Portland is building a new filtration facility to keep our drinking water safe and abundant for generations to come. Filtration will remove the microorganism Cryptosporidium from the Bull Run supply and must be completed by September 2027 to comply with state and federal water quality regulations.

The improved treatment facilities were completed in April 2022 to help make water from the Bull Run less corrosive to lead and other metals found in some home and building plumbing.
