This is a normal occurrence in our system, as our water supply originates in the Bull Run Watershed near Mt. Hood. Before the water is treated and enters the supply system, it seasonally takes on a tint from organic materials that are washed into the streams and the reservoirs in the watershed. Drinking water from the Bull Run is not filtered, which is often why the color can be seen in tap water or staining the filters in your business or home.
The color you see is produced by tannins in organic material, much the same as the color you find in an ordinary cup of tea. There is nothing harmful to your health from these tannins. The color affects only the appearance of the water, and not the quality.
The length of the fall color season varies with the strength and duration of the rains we experience during this time of year and how much organic material is carried into the system.
As always, the Portland Water Bureau constantly monitors the water entering the distribution system to ensure that it continues to meet all state and federal regulations for safe drinking water, and customers are notified of any changes that may affect the quality of the water we bring to you. Any questions may be directed to the Water Quality Information Line at 503-823-7525.
Substantial rains in the watershed started refill of the reservoirs on October 23, adding 1.8 billion gallons in just two days. As of this morning, October 27, there were 5.3 billion gallons, or about 53 percent of usable drinking water storage in the Bull Run reservoirs. The total usable water supply of the Bull Run reservoirs are 9.9 billion gallons.
The Bull Run reservoirs can hold up to 17 billion gallons.
With a mix of hands-on and classroom-style teaching, the workshop invites participants to learn about local geology and hydrology, the vital role groundwater plays in our drinking water system, and what we can all do to protect this important resource. After the workshop, participants can take an optional half-hour guided tour of the Portland Water Bureau groundwater facility.
The workshop is appropriate for adults and high-school students. Light refreshments will be provided.
Online pre-registration is required and the class size is limited to 35 participants. Don’t wait to sign up!

As the project to make necessary changes to the Washington Park reservoirs reaches the 60 percent design phase, the Water Bureau will meet with the Community Sounding Board to further discuss the construction and traffic control plans, and to share with them further refinements of the visible features designs.
The Sounding Board is comprised of representatives of Southwest Portland neighborhood associations, park users, and Portland Parks & Recreation staff. The group has been meeting since early July 2014 to develop concepts for the features on top of the underground 15 million gallon reservoir and the overflow-dechlorination tanks in the footprint of the existing open reservoirs.
The meeting – which is open to the public -- will be on Wednesday October 29, from 6 to 8 p.m. at the Zion Lutheran Church at 1015 SW 18th Avenue. The church is located at the Southwest corner of SW 18th Avenue and SW Salmon Street. There is limited parking behind the church, but plenty of street parking nearby. The church is easily accessible from the Kings Hill MAX stop and bus route #15.

The rainy weather has begun, a sure sign that fall is on its way. The days are getting shorter, the leaves are starting to turn color, and our gardens are starting to go dormant for the winter. As a result, now is a great time to prepare your garden and watering systems for fall and winter. Here are some tips to get you started:
