Following the 2016 ice storm, we applied for grant funding from the Federal Emergency Management Agency to make resiliency improvements to our electric system to reduce the frequency and duration of storm-related outages in several areas prone to storm damage.The agency has thus far approved 15 of the 16 proposed reliability projects, and will fund 75 percent of the cost, estimated to be about $3 million. The final project should be approved later this spring.Find Out More
Fourteen full crews worked in the McKenzie River area Sunday, whittling down the number of upriver customers without power to less than 860 as of 3 p.m. With cell service still down in the area, reports from field crews are limited to radio communication, making it more difficult to keep upriver restoration information current. Starting with more than 14,000 customers out of service on Monday, fewer than 920 of our customers now remain without service on Sunday. Most repair work in Eugene is limited to incidents with just a few services out of power. Several smaller teams have spread out across Eugene to continue working these service restorationsFind Out More
In our ongoing efforts to make more information available to customers, we want to share a new tool: the Power Outage Map. The map, accessible at eweb.org/outage, provides the general location of a power outage within EWEB’s service area, along with various details that will emerge as field technicians investigate the cause and determine repair strategies.Find Out More
In partnership with the Bethel School District, we’ll open the first emergency water distribution station at the Bethel Farm on Oct. 6 with a “FILL UP at the Farm” grand opening event. A key component of EWEB’s ongoing initiative to prepare for emergencies, whether earthquake, forest fire or other disaster, is to establish at least five of these geographically dispersed emergency water stations within the next five years.Find Out More

A recent water pipeline assessment that relied on a free-swimming acoustic sensor called a SmartBall® is an example of using innovative, cost-effective methods to maintain our infrastructure.
Most people know that Eugene's drinking water comes from the McKenzie River. We divert water from the McKenzie at our intake outside of Springfield, and pump it to the Hayden Bridge Filtration Plant where it is filtered and disinfected. What happens between the Hayden Bridge plant and customer taps is, for many, a mystery. Water travels through hidden, underground pipelines 24 hours a day, 365 days a year, beneath roads, sidewalks, rivers and buildings. These water pipelines are the backbone of our community's drinking water system.
Transmission mains are large-diameter pipelines that convey treated water to storage reservoirs or to the smaller-diameter pipes that distribute water to homes and businesses. EWEB maintains 36 miles of transmission mains—enough to connect Skinner Butte and Spencer Butte almost seven times.
Maintaining the transmission lines is no small job.
First of all, transmission lines are big. Your average 5-year-old could stand inside of one with headroom to spare. They also are long—sometimes several miles long, and buried deep underground—usually 30 inches or so.
Two of EWEB's primary transmission mains leave the Hayden Bridge treatment plant and convey an average of 25 million gallons of water each day, over a distance of four miles into the Eugene city limits. And in some cases, the mains are close to or directly beneath existing homes, businesses, roads and natural areas, making them hard to assess and even harder to repair or replace. The 45-inch Hayden Bridge transmission pipe, constructed in 1948, travels underneath Interstate-5. Another 30-inch main travels under the Valley River Inn. Several of our transmission pipes journey beneath the Willamette River at different locations around town.
And like most pipes, these transmission lines can leak from time to time.
Over the last few years, EWEB crews found and repaired two "pinhole" leaks on the 45-inch Hayden Bridge main. Fortunately those leaks were under a grassy surface near a bike path, and therefore relatively easy to repair. But there's always a chance that a small leak could exist underground, undetectable from the surface. Assessing the condition of the pipes, and finding and fixing small leaks before they become big problems, is important but difficult work.
In 2016 a leak was discovered on EWEB's 45-inch transmission line near the Hayden Bridge Water Filtration Plant.
"Infrastructure decisions affect the whole community for generations to come, and replacing buried infrastructure, in particular, is very costly," said EWEB civil engineer Nathan Endicott. "It's important to know the condition of existing pipes so that we can effectively plan and budget for both immediate and long-term projects." Nathan and his engineering colleagues have been researching effective ways to check transmission lines for leaks and, after a lengthy review and planning process, they landed on an innovative solution called a SmartBall.
A SmartBall is an acoustic sensor wrapped in a foam covering. It travels through the pipeline listening for the sounds of leaks and air pockets. Its highly sensitive acoustic sensor can locate pinhole-sized leaks, while a monitoring device marks the location of the leak. It's accurate to within a few feet of an actual leak.
"Thanks to modern technology, we have many options available for leak detection and condition assessment," said Nathan. "An EWEB review committee selected the SmartBall solution because it was proven effective for inspecting miles of pipe in a day, and could be used for a fraction of the cost of other acoustic inspection methods." Using the SmartBall, EWEB engineers were able to assess more than five miles of transmission main from Hayden Bridge to headquarters in less than six hours.
Check out this video to learn more about how the SmartBall works.
Engineers were pleased, and a little surprised to learn there are currently no leaks in either of the transmission mains from Hayden Bridge. "Considering the age of the pipes, and the stress they sustain over time, we expected to find at least a few small leaks, if not worse," said Nathan. "But we're fortunate that the engineers who designed this part of the water system some 60 years ago used good, durable materials."
The transmission mains that Nathan and his team recently assessed are constructed of thick steel. Steel pipes are known to perform well, even under extreme external loads and unusual conditions, such as uneven ground and soil movement. "Maintaining infrastructure is a critical issue across the nation, and many utilities are facing huge problems with less durable pipes like pre-stressed concrete cylinder pipes that, when they fail, they fail catastrophically," said Nathan. "We have high-quality buried infrastructure, but we still have to make ongoing investments to maintain that infrastructure. It's a community-wide benefit and a community-wide responsibility."
EWEB owns and maintains over 800 miles of pipes, 23 enclosed reservoirs and other facilities that deliver water to customers taps. Many of today's water systems were built more than 50 years ago. Thanks to investments by past generations, we've had the luxury of delaying major infrastructure replacements necessary to maintain reliable water delivery. Now it is our turn to make the investment to maintain safe, reliable drinking water for future generations.
EWEB's Water Reliability Initiative includes several infrastructure reliability projects over the next 10 years, including replacing water mains, upgrading interties, upgrading or building new reservoirs, adding back-up electrical power to pump stations, expanding the Hayden Bridge Filtration Plant, and developing alternative water sources. "We are committed to regular maintenance so our community's water system stays in excellent shape," said Nathan. "Since every dollar spent on infrastructure ultimately affects customer bills, it's important to make those investments strategically."
Assessing the condition of our water infrastructure with solutions like the SmartBall allows us to focus resources on critical work such as seismic upgrades and developing alternative water sources, with the confidence of knowing we can defer work on pipes that are in generally good condition.
