Water Quality Trivia

B. The Portland Water Bureau maintains water pressure in the system to ensure that water leaks out of breaks in the system, preventing outside material from entering.

Water pressure not only keeps water moving in our system, it also protects water quality. As long as our system is under pressure, water is forced out of cracks or holes in pipes, which prevents soil and other contaminants from entering. If there is a total loss of pressure somewhere in our system, which can sometimes occur with a large main break, a temporary boil water notice may be issued to affected customers. 

Questions or concerns about water quality? Contact the Portland Water Bureau’s Water Line at 503-823-7525.
