The Portland Water Bureau is completing construction on a 1.3-million gallon reinforced-concrete underground drinking water tank and a 1,408 square-foot pump station in northwest Portland. Identified in the city’s water system as the Forest Park Low Tank, the 73-foot diameter tank and adjacent pump station are part of an overall plan to better serve the current and future water needs of residents.  The tank will serve homes at higher elevations in the area and improve water capacity for emergency fire protection.

The tank, built 41-feet deep into the ground, is being backfilled, covered, and compacted with layers of soil. Eventually native grasses will completely cover the tank. Over the next couple weeks, crews will fill, test and then disinfect the tank before it is connected to the operating water system.

The intricate system of piping running from the tank and connecting to the water main under NW Skyline Boulevard has been installed. The pipelines will soon undergo pressure testing to ensure the integrity and soundness of the pipes and joints within the pipeline. 

The walls and floor of the pump station have been constructed. Using gravel, crews have backfilled around the rectangular-shaped pump station.

The project is scheduled for completion in late May 2014. For additional information, visit the project webpage.

Guided Walking Tours Offered of Proposed Work Areas in Mt. Tabor Park

Add a Comment

In order to satisfy an unfunded federal water quality mandate, the City of Portland is required to disconnect Portland’s open air reservoirs, including three at Mt. Tabor Park. This work is proposed to begin in early 2015. 

During April and May, the Portland Water Bureau is offering guided walking tours of the proposed work areas in Mt. Tabor Park. Lasting one hour, the tours – conducted by Water Bureau staff – point out work areas and explain the proposed project’s scope.

This tour is related only to the work to decommission the open reservoirs. There will be a separate public process on the future of the reservoir sites at a later date.

The tours are free and space is limited to 20 people each tour. Reservations are required.

Guided walking tour reservations can be made in two ways:

1.  Sign up using the online reservation form.
2.  Contact the Public Information Group at 503-823-6926, Monday through Friday, 8:00 am to 4:00 pm.

If you make a reservation by phone, please make sure to state your name, provide your contact information, include two walking tour dates options, and note any special accommodations or considerations the Water Bureau needs to be aware of before you arrive to participate in a tour.

The walking tours, conducted rain or shine, will meet at the park entrance at SE Lincoln Street, east of SE 60th Avenue. The tour will walk to Reservoir 1 and 5, and then down the stairs to Reservoir 6. Participants are encouraged to arrive five minutes before the one-hour guided tour is scheduled to begin. Please wear sturdy walking shoes as the some of the path is uneven, and a hat and water bottle are encouraged.

'In-car' tours are available upon request for people with disabilities. Please contact the Water Bureau no later than five (5) business days prior to the tour date by phone at 503-823-6926.

Tour Schedule:

·  Tuesday, April 29, 2014 from 6:30 pm to 7:30 pm

Public Invited to Washington Park Reservoir Improvements Project Meeting

Add a Comment

The public is invited to attend another Community Sounding Board meeting on the city’s Washington Park Reservoir Improvements Project. The meeting is Wednesday, April 30, from 6:00 pm to 8:00 pm at the First United Methodist Church, 1838 SW Jefferson Street, Room 202.

During the meeting, the citizen-member group and public will get a project update and have the opportunity to meet the construction contractor, Hoffman Construction Company, which will begin work on the project in spring 2016.

The Sounding Board is comprised of neighborhood association representatives, park users and Portland Parks & Recreation staff, who are working with the Portland Water Bureau to determine the visual features of the two reservoir sites inside Washington Park.

Since July 2013, the Sounding Board has been providing ideas, advice and critical feedback to the Water Bureau project team and its design engineering consultants on options for water features, amenities, and landscaping of the historic sites. 

In addition to the public Sounding Board meetings, the Water Bureau has also held open houses, community briefings, and conducted mailings and website surveys to gather public input and feedback on design concepts.

The Washington Park Reservoir Improvements Project will replace upper Reservoir 3 with a 15-million gallon underground reservoirs and repurpose the decommissioned lower Reservoir 4 to serve as an overflow-storm water retention and de-chlorination facility. In addition, due to a historic landslide – dating back to the original reservoir construction in 1894 – the Water Bureau must take steps to stabilize the hillside.

To learn more about this project, visit, or contact Water Bureau Public Information staff at 503-823-6926.

Click on “Projects” to the right of your address at the top of the page.

There are 2 choices, 'Capital Improvement Projects' and 'Public Works Projects'.

The list of Capital Improvement projects includes a description of the project, and a schedule for the design and construction phases within one-half mile of the property. This information can be useful to residents and businesses in planning their own private property improvement projects, and knowing when their streets may be disrupted.

The Public Works projects shown are privately-funded projects (also known as development-initiated projects).  These projects also involve public infrastructure.
