The cost for planning, design, and construction of a filtration plant is estimated between $350 million and $500 million. Operating costs are likely to increase $5 million when the plant becomes operational. 

The current average monthly water bill for single-family residential customers is $36.10.

To fund a $500 million project, the bureau anticipates 10 years of 2.2 percent rate increases, which would increase average monthly bills by approximately $12.50 per month.

During the annual rate-setting process, PWB will make every effort to minimize rate impacts. One of the ways to reduce impacts is the launch of the expanded discount programs to lessen the impact of rising water rates on low-income customers.

The Portland Water Bureau offers financial assistance in the form of payment arrangements, bill discounts for sewer and water charges, crisis vouchers, fixture repair services, and the Utility Safety Net program.
