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

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, the Water Bureau 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.
