Check out the 2019 Drinking Water Quality Report!

The 2019 Drinking Water Quality Report outlines how we are continuing to deliver clean and safe drinking water to nearly a million customers.

Portland’s drinking water comes from two high-quality sources—the Bull Run Watershed and Columbia South Shore Well Field.

What’s in the Report?

The report summarizes water quality results for 2018 and includes information about how we monitor, treat, and distribute your drinking water. The report also provides information on Portland’s drinking water system and how customers can reduce their exposure to lead in drinking water, including by requesting a free-lead-in-water test kit.

Making Excellent Water Better

The report also highlights two major treatment improvements Portland is undertaking. These improvements will provide increased public health protection against lead in household plumbing and Cryptosporidium, an organism that can potentially cause illness. These improvements will also result in more consistent water quality and prepare the water system for future regulations.

How to Access the Report

The Portland Water Bureau is mailing a postcard this week to inform every customer about the availability of this report online. Customers can request a paper copy, either online or by phone.

Do you know someone who could benefit from translated versions of this report? The report is available in Russian, Vietnamese, Chinese, and Spanish. It is also available in screen reader-optimized large print in English.

The report can be found online or by calling the Water Quality Line at 503-823-9444.

June 2019 Update: Washington Park Reservoir Improvement Project

As the weather warms and the Washington Park gardens wake up, crews have been busy making significant headway at the Washington Park Reservoir Improvement Project work site. Accomplishments include:

  • Pouring the first wall sections
  • Setting up stations to infuse concrete with liquid nitrogen which help regulate concrete cooling temperatures
  • Removing of two dead trees outside of the construction work area by Portland Parks & Recreation.
  • Installing the second tower crane

Cooling Concrete with Liquid Nitrogen

Managing the placement and curing of concrete at the Washington Park Reservoir Improvement Project is a delicate act, particularly during the warmer months. As concrete is “batched at the plant” and then is placed and cures, its temperature heats up. During warm weather, it can heat to temperatures that cause thermal stresses and potential concrete damage. To reach the needed strength for the finished concrete, the heat levels need to be controlled to maintain the tolerances required in the reservoir design.

Watch an example video of liquid nitrogen
being injected into concrete.

To ensure the concrete does not overheat during the warmer months, the contractor will cool the concrete with liquid nitrogen. In the Reservoir 4 area, a liquid nitrogen tank and four bays are being temporarily installed. As concrete trucks enter the project site, they will pull into one of the bays where the load will be injected and mixed with liquid nitrogen. Then the truck will move to the construction zone in Reservoir 3 and the concrete will be pumped into the waiting forms.

Things to know about liquid nitrogen:

  • There is the possible presence of fog at the work site. The boiling point of liquid nitrogen is -321 degrees Fahrenheit. When it hits air, it boils and chills the surrounding air, causing the humidity in the air to condense into fog. When this process is in operation, neighbors may notice a fog in the area of Reservoir 4.
  • Liquid nitrogen is cold enough to cause severe frostbite upon contact with living tissue. Workers will be wearing proper safety gear when injecting the nitrogen into the concrete trucks to help prevent contact or inhalation of the extremely cold vapor.
  • A common use of liquid nitrogen is in the freezing and transport of food products.

About this Project

The new 12.4-million gallon, seismically reinforced underground reservoir is being built inside the footprint of the former Reservoir 3. (upper) A new reflection pool on top of the reservoir will retain the historic look and feel of the original. The new reservoir has been engineered to withstand ongoing landside encroachment and potentially catastrophic effects of a major earthquake.

The new reservoir will supply water to Portland’s west side, serving approximately 360,000 people, including all downtown businesses and residents, 20 schools, five hospital complexes, and more than 60 parks.

This system of water conveyance and storage makes Portland a livable and thriving community, ensuring public health and economic viability.

Portland Observer: How Self Enhancement, Inc. and the Portland Water Bureau Assist Low Income Customers

This story was reported by The Portland Observer. The full article can be read here.

Representatives from Portland Water Bureau and Self Enhancement, Inc. are on a mission to let economically struggling families know about the financial assistance options the city utility offers, which have been increased this past year.

The Water Bureau has expanded discounts for qualifying low income households and those in temporary financial crisis, opened a relocated and more transportation-friendly office, and established community partnerships with culturally specific groups, like Self Enhancement Inc., the non-profit serving the African American community of Portland.

All those actions spelled good news for Iva, a senior citizen who was living off of a fixed social security income when health issues brought her in and out of the hospital for a six week stretch. Her water bills fell behind and she accrued late fees, unable to do much else other than focus on her health.

Thanks to Water Bureau’s utility crisis voucher—which recently increased from $150 to $500—Iva was able to get back on top of her payments after she got well.
