Make a New Year’s Resolution to Improve your Water Footprint

Add a Comment

With the temperature on the chilly side, thinking about water (the non-frozen variety) isn't high on the agenda for most people. But we always need drinking water — and clean drinking water at that.

In Portland we are blessed with an abundance of water that most of us take for granted. This is the season of thinking about what we will do in the new year to be and do better. How about reducing your water footprint? Here are a few suggestions:

  • Install high efficiency showerheads to reduce waste — save five to eight gallons per shower.
  • Limit showers to five minutes
  • Consider upgrading to a water and energy efficiency washing machine
  • Run your dishwasher only when it's full
  • Replace your older toilet with a WaterSense-labeled High-Efficiency toilet that uses 1.28 gallons per flush or less
  • Give up bottled water — it takes 1.85 gallons of water just to manufacture the plastic for one 12-ounce bottle.

The list goes on.

So think about what could work for you and make a commitment to do at least one thing this coming year.

Good luck and happy new year!

Maintaining Water Quality in Portland’s Neighborhoods, Mile by Mile

Add a Comment

The Portland Water Bureau works year-round to deliver high quality drinking water to its customers. One of the regular maintenance tasks that occurs throughout the city, neighborhood by neighborhood, is unidirectional flushing or UDF.UDF completed in 2014

Unfiltered systems like Portland need to routinely clean the network of pipes to improve water quality. Over time, very fine sediment and organic matter from the Bull Run settle out of the water and accumulate in the bottom of the pipes. Unidirectional flushing gets those sediments out by forcing water in the pipes to flow at much higher speeds than normal. Flushing crews temporarily close valves to isolate sections of pipe creating one-way flow and increased velocity, then the water and any sediments in the pipes are flushed out through an open fire hydrant. 

The UDF crew has finished flushing in the northwest heights and parts of Forest Park neighborhoods. The area served was roughly from NW Lambert St south to Cornell Rd and Skyline Blvd/Ramsey west to Mill Pond Rd. More than 15 miles of 4, 6 and 8 inch water mains were flushed in under four months by a two person crew.

So far this year, more than 43 miles of water mains have been flushed in southwest and northwest Portland neighborhoods.

Water Bureau Submits Land Use Review Application for Washington Park Reservoir Improvements Project; Public Comment Period & Hearing in January 2015

Add a Comment

In order to comply with federal and state mandates, and ensure a healthy, resilient, and secure water system, the Water Bureau is moving forward with a project to update the Washington Park reservoir site. 

On December 15, 2014, the Water Bureau submitted the first of two Land Use Review applications for the proposed Washington Park Reservoir Improvements Project. In January 2015, BDS will issue a notice of public hearing and open the public comment period.

The Water Bureau’s Washington Park Reservoir Improvements Project proposes to build a new below-ground reservoir in the same general footprint as the existing upper Reservoir 3, with a reflecting pool on top. The lower Reservoir 4 basin and the slope to the west are needed to provide landslide abatement; the slope will be restored to its pre-reservoir condition. Reservoir 4 will be disconnected from the public drinking water system and a lowland habitat area/bioswale and a reflecting pool are also proposed in the Reservoir 4 basin. Work will primarily be within the Historic District.

Proposed project

Land Use Application #1
The initial Land Use application (Type IV, heard and decided by City Council following a public hearing) proposes the removal of the Weir Building (screen house), portions of lower Reservoir 4’s basin, and upper Reservoir 3’s basin. The gatehouses, dams, and other historic features will be protected and restored.

Land Use Application Package
In spring 2015, a second Land Use application package with two components will be submitted for construction of a new covered reservoir, reflecting pools, lowland habitat area/bioswale, walkways, and historic preservation and rehabilitation actions. The features, which are described in the first Type IV land use application, will offer the public enhanced access to the new surface water features and classically-designed gatehouses, dams, and related structures. These two reviews will be Type III. The Historic Resource Review will be heard and decided by the Historic Landmarks Commission following a public hearing. The Conditional Use and Environmental Review will be heard and decided by a Hearings Officer following a public hearing.

Before construction begins and permits can be issued for the work, the Land Use Review applications must be approved.

Community Sounding Board MeetingPublic Involvement
The applications are a result of a robust public involvement process that included multiple public open houses and nine Community Sounding Board (CSB) meetings that guided design for the required visible features of a new reservoir in Washington Park.  

CSB members included representatives from:

  • Portland Parks & Recreation
  • Neighbors West-Northwest District Coalition
  • Arlington Heights, Goose Hollow Foothills League, Northwest District, Northwest Heights, and Sylvan-Highlands Neighborhood Associations

Portland’s preservation organizations, including the American Institute of Architects (AIA) and the Historic Preservation League of Oregon, also participated in the public involvement process to help determine the future of the historic site.

The project addresses four major reservoir issues:

  • Recurrent landslide damage
  • Compliance with federal law
  • Seismic vulnerability
  • Deterioration of the 120 year-old structures

A copy of the land use applications submitted to BDS will be posted on the project webpage at The Bureau of Development Services maintains the official application record, which tracks updates and revisions over time.

Portland Water Selects Innovyze Smart Water Network Modeling Technology

Add a Comment

The Portland Water Bureau has selected InfoWater software to support the bureau’s water distribution network modeling and management needs.

The new software, developed by Innovyze, will replace software the Water Bureau has utilized for 20 years and will further enable the bureau to address critical planning, design, operational, and water quality issues. 

InfoWater is an example of hydraulic network analysis software. This type of specialized software will offer Water Bureau staff in the Operational Analysis, Engineering Planning, Engineering Design, and Water Quality Compliance Groups the tools to: 

  • Model the water system’s pipe network and simulate its behavior.  For example, it can simulate what pressure and flow should be at any point in the system, based on given operating parameters at one moment in time (which valves are open/closed, how much water is in the reservoirs and tanks, etc.). 
  • Simulate the water system’s pipe network behavior over an extended time period.  The InfoWater software will be able to simulate time-based operation of the full water system over a 10- to 15-day period. This capability is very important for simulating water age within the system, or for determining how flow from our Groundwater source might travel through the system during a transition, for example.
  • Model and analyze system behavior for shutdowns, water quality events, and operational changes.
  • Assist in designing new infrastructure.

Additional benefits of the InfoWater software include: 

  • Runs inside the GIS system, offering the convenience of GIS tools.  For example, the older software didn’t store street names, so when searching for a specific address in the network model, both systems had to be open side-by-side and to visually compare shapes. The GIS provides many other spatial-analysis and mapping tools that the older software didn’t offer.
  • Directly imports and exports network model data in EPANET format.  EPANET is basic hydraulic network modeling software available for free from the US EPA.  The EPANET file format has become the world standard for exchanging network model files.  Because the old software was not able to read and write EPANET files, Operational Analysis staff developed a translator that lets them move data from the old format into EPANET, where the new software can read it.
  • The new software provides many bonus features, such as automated fire-flow calculations, energy cost analysis, and valve criticality analysis. 

According to staff in the Operations Group, InfoWater will offer the Water Bureau valuable tools for planning, designing, and operating the infrastructure.  The Water Bureau will be transitioning to the new software over the next year or so – learning the new software and moving data links from the old to the new format. This is definitely an investment in many years of water system excellence. 

The Portland Water Bureau joins Seattle Public Utilities, City of Atlanta, and many other large water utilities in using this product.
