Mt. Tabor Park Reservoir Preservation Work Set to Begin in November 2017

Construction activities to repair and rebuild the historic features of the Mt. Tabor Park reservoirs will begin in November 2017.

The areas impacted are the reservoir loop walkway around Reservoir 1 and the concrete stairway on the dam face between Reservoirs 5 and 6.

The Reservoir 1 walkway will be closed until Spring 2018.

Reservoir 1: November 2017—May 2018

Concrete restoration will begin in November 2017 and conclude in late spring 2018. Contractors will conduct a complete makeover of the south wall and the walkway around Reservoir 1 as well as miscellaneous exterior concrete repairs to the gatehouses at Reservoirs 5 and 6 and the Weir Building. As this work is weather dependent, an actual completion date cannot be determined. Work will begin the first week of November 2017. Reservoir 1 will be drained so that consultants can conduct a basin condition assessment.

Dam Face Fencing: November—December 2017

The community has prioritized the replacement of fencing that isolates the dam face between Reservoirs 5 and 6 from park activities. This isolation and protection is required by the Oregon Water Resources Department Dam Safety Program. The existing chain link fence will be removed and a more visually compatible and complementary fence will be installed. A new railing on the south side of the concrete staircase will also be installed. Some non-native landscaping has been removed, and native plants will be planted in select areas. Work will begin the second week of November and will take three to four weeks to complete. The concrete staircase on the dam face will be closed during certain times during construction. Please obey all construction signs and fencing.

Preservation construction activities on select historic reservoir and gatehouse features are scheduled for the next three years. The public will be kept informed of the construction schedule.

There have been many changes to the Portland Water Bureau operations at Mt. Tabor Park in the past few years, most notably the disconnection of the open reservoirs from the water system.

While the reservoirs no longer supply drinking water to city residents, they continue to be an asset to the City, and are an integral and historic part of Mt. Tabor Park.

To that end, the City of Portland has committed $4 million over the next several years to begin historic restoration of the integrity of the reservoirs and their buildings, walls and fences. 

A project team comprised of Portland Water Bureau staff, and representatives of the Mt. Tabor Neighborhood Association and the Friends of Mt. Tabor Park are managing the development and implementation of the activities related to the Mt. Tabor Reservoirs Historic Preservation Project.

There are two programs associated with the project:

  1. structural historic preservation
  2. historic interpretation and education

Both programs are scheduled to be completed before 2020. 

Restaurant and Hotel Owners: Lower Costs to Save Money. Upgrade Your Commercial Ice Machine.

Replacing an older water-cooled ice machine with an Energy Star-labeled air-cooled model is a great way to save water and money. And your incentive to make the change just got a little sweeter.

NEW Rebate for Energy Star-Labeled Commercial Ice Machines

The Portland Water Bureau Water Efficiency program now offers a rebate for commercial ice machine upgrades. When you replace a water-cooled ice machine with a high-efficiency Energy Star-labeled air-cooled ice machine, you can qualify for a rebate worth 50% of the cost of the new eligible ice machine up to a maximum of $3,000.

Portland Water Bureau to Host Free Building Water Quality Workshop.

Building Water Safety Plans Workshop flyerBuilding water quality is a newly-recognized public health concern, as water quality can decline rapidly in buildings due to stagnation, low flow, and other factors.  Best management practices can reduce the risk of Legionella and other pathogens from forming inside a building’s water system.

This workshop will cover:

  • How building water quality is affected by opportunistic premise plumbing pathogens, corrosion, and building plumbing design.
  • Real-world examples on how to use hazard analysis and critical control point (HACCP) principles to understand and manage building water quality.

This workshop will be of interest to large building owners and operators, facilities staff, public health officials, drinking water regulators, and communications staff in these organizations

Nov. 6, 2017 Cryptosporidium Monitoring Update

Nov. 6 Cryptosporidium Monitoring UpdateThe Portland Water Bureau received additional results from ongoing monitoring from the Bull Run Watershed intake for Cryptosporidium, a potentially disease-causing microorganism. Between Oct. 29 and Nov. 1, two oocysts were detected from 50-liters of water collected on Sunday Oct. 29. No additional Cryptosporidium was detected from the 150-liters sampled Monday Oct. 30 through Wednesday Nov. 1.

Past Detections

Prior to these detections, Cryptosporidium was last detected on Tuesday, Oct. 24 when two oocysts were detected from 50 liters of water from the Bull Run. The bureau continues to use the Bull Run as its primary source of drinking water.

About Cryptosporidium

Exposure to Cryptosporidium can cause cryptosporidiosis, a serious illness. Symptoms can include diarrhea, vomiting, fever and stomach pain. People with healthy immune systems recover without medical treatment. According to the Center for Disease Control (CDC), people with severely weakened immune systems are at risk for more serious disease. Symptoms may be more severe and could lead to serious or life-threatening illness. Examples of people with weakened immune systems include those with AIDS; those with inherited diseases that affect the immune system; and cancer and transplant patients who are taking certain immunosuppressive drugs.

EPA has estimated that a small percentage of the population could experience gastro-intestinal illness from Cryptosporidium and advises that customers who are immunocompromised and receive their drinking water from the Bull Run Watershed consult with their healthcare professional about the safety of drinking the tap water. The Portland Water Bureau and Burlington, City of Gresham, City of Sandy, City of Tualatin, Green Valley, GNR, Hideaway Hills, Lake Grove, Lorna Portland Water, Lusted, Palatine Hill, Pleasant Home, Raleigh, Rockwood, Skyview Acres, Tualatin Valley, Two Rivers, Valley View and West Slope Water Districts receive all or part of their drinking water supply from the Bull Run. To learn if your drinking water comes from Bull Run, please contact your local drinking water provider.

No Prior Increase in Cryptosporidium-Related Illnesses

Public health surveillance during and after a similar series of low-level detections from January through March of this year did not see an increase in Cryptosporidium-related illness. The general public is not advised to take additional precautions.

Water Sampling Results

The public and the media are encouraged to view all sampling results posted to the City’s website at The media will also be notified of any further low-level detections on at least a weekly basis, if they occur. The bureau will notify the media and public immediately should further test results indicate a risk to public health and precautions are necessary.
