The new system is composed of a large towable generator, electric submersible pump, above ground hoses, and sprinkler system. The generator powers a pump which is placed directly into the reservoir drain vault. The pump is attached to above ground hoses.
A Water Bureau electrician works on the Pump control panel.
The hoses are used to disperse the dechlorinated water onto newly established native grasses and shrubs planted around the Powell Butte Nature Park site.
Sprinkler for Flygt pump.
Although the bureau has a permit to discharge dechlorinated water into Johnson Creek, this system provides an environmentally friendly alternative.
The Forest Service has proposed an administrative change for the Bull Run Watershed.
This administrative change would update the land use allocations in Bull Run to be consistent with legislation passed by Congress in 1996 and 2001 to prohibit timber harvest in the watershed. This administrative change would update the land use allocations in the Mt. Hood Land and Resource Management Plan (1990), as amended by the Northwest Forest Plan (1994).
The change in timber harvest policy has already been made by Congress. The administrative change to the Forest Plan is, however, open for public comment for 30 days, until August 10, 2015.

Flushing will occur between SE 111th Avenue on the west, SE 145th Avenue on east, SE Holgate Boulevard on the north, and SE Brookside Drive, SE 122nd Drive, and SE Blackberry Circle on the south. CLICK HERE to view a map of the flushing area.
Using Water Wisely this Summer
Flushing water from a hydrant is an important and necessary practice to maintain water quality in the distribution system. This practice is used to flush discolored water from the pipes, keep water fresh in low use areas and dead-ends, and to clean inside pipes. This process is regularly monitored by Water Bureau staff to make sure the water is used wisely while maintaining water quality.
What you can Expect to See
Unidirectional flushing will have minimal impacts to customers. If you see hydrant flushing crews working in the area, please drive carefully and treat them like any other road construction crew.
During flushing, residents in the immediate vicinity of flushing may notice temporarily discolored water and lower than normal water pressure. The discoloration does not pose a health risk. However, avoid using tap water or running the washing machine or dishwasher until your water runs clear. After flushing, if you still experience discolored water, turn on each cold water faucet in your house and allow them to run for several minutes or until the water is clear.
Flushing usually occurs Monday through Friday, between 9 a.m. and 3 p.m.
How Does UDF Work?
UDF works by forcing water in the pipes to flow at much higher speeds than normal. Flushing crews first open and close valves to isolate sections of pipe, and then the water and any sediments in the pipes are flushed out through an open fire hydrant. Residents may observe water gushing from an open hydrant.
Improving and Maintaining High-Quality Drinking Water
Drinking water systems, especially 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. While the sediments are generally harmless, they can make the disinfectant in the water less effective. Additionally, sudden changes in the flow of water can disturb these sediments resulting in discolored water.
Call the Portland Water Bureau Water Line from 8:30 am to 4:30 pm at 503‐823‐7525 with any questions or to report ongoing water quality problems. For more information, updates, and maps, visit www.portlandoregon.gov/water/udf.
Reservoir 1 in drawdown, July 2015
The U.S. Drought Monitor identified Portland as experiencing a moderate drought in its weekly map of drought conditions last week.
It is important for Portland metro area water users to note that while the Drought Monitor has made its assessment based on factors including local stream flows, temperature and soil moisture, Portland does not have a water supply shortage.
The report itself explains, “Municipal water supplies for the metropolitan areas of western Oregon and Washington are adequate even though the other indicators are showing intense drought development, especially over the last two months.”
Portland’s water source, the Bull Run Watershed, is a low-elevation watershed that gets its water primarily from rain, not snow. The watershed gets approximately 135 inches of rain each year, about 3-4 times more rain than we get here in town.
Thanks to careful planning, the Portland area has a high-quality secondary water source. The Columbia South Shore Well Field can be used in addition to the Bull Run supply during dry periods.
The Bull Run watershed, in combination with the Columbia South Shore Well Field, is capable of meeting Portland’s water needs throughout the summer.
A Q&A about Portland’s water supply can be viewed here. You can also find updates at the Portland Water Bureau’s Seasonal Water Supply Planning webpage.
The U.S. Drought Monitor is produced by the National Oceanic and Atmospheric Administration, the U.S. Department of Agriculture and the National Drought Mitigation Center at the University of Nebraska-Lincoln.
Currently, 20 counties in Oregon are under emergency drought declarations and approximately 98 percent of the state is experiencing drought.
"I am asking all Oregonians to do their part to use water wisely," said Governor Brown. "Water is the foundation for local economies and ecosystems, and essential to the health and well-being of Oregonians. Drought is a slow moving disaster, adopting responsible water use practices now will help reduce the impact of drought for years to come."
While Portland is not experiencing a water supply shortage, nor do we expect to this summer, the Portland Water Bureau joins Governor Brown in helping to raise water awareness at home, play, and work.
Portlanders are encouraged to visit the Water Bureau’s Water Efficiency webpage for information and technical resources on using water efficiently and cost effectively.
