24-hour sewer construction on N Williams between N Fargo and N Cook

Traffic Advisory

March 16, 2015

Beginning today, a sewer repair project will close one traffic lane on N Williams Avenue between N Fargo and N Cook 24 hours a day for up to three days. Motorists and bicyclists should expect delays in the construction zone.

For the last week, repair work at that location has closed a traffic lane during daytime work hours only. Daytime only construction hours will resume there by the middle of this week.

Environmental Services is replacing a deteriorated manhole at N Williams Avenue and N Fargo Street as part of a project to provide public sewer access to a property with a nonconforming sewer connection.

Combined Sewer Overflow (CSO) Advisory

March 15, 2015

Heavy rain causes sewer overflow to the Willamette River

Heavy rain this weekend caused Portland’s combined sewer system to overflow to the Willamette River. The public should avoid contact with the river from the Sellwood Bridge downstream to the Willamette’s confluence with the Columbia River near Kelley Point Park.

As a precaution, the public should avoid contact with river water until 48 hours after combined sewers stop overflowing. More details are posted at www.portlandoregon.gov/bes/overflow.

It is especially important to avoid recreational activities, such as jet skiing or swimming, during which water could be swallowed. CSOs are contaminated with bacteria from untreated sewage. Environmental Services recommends these precautions to protect public health.

People who fish within 48 hours of a CSO event should wash their hands following contact with river water. Those who choose to eat fish caught in the Willamette River within 48 hours of a CSO event should cook the fish thoroughly to kill bacteria.

Portland’s combined sewer system carries sewage and stormwater runoff in the same pipes. During very heavy rainstorms, the increased stormwater runoff can cause combined sewers to overflow into the Willamette River.

In December 2011, Portland completed a 20-year program to improve the sewer system and reduce Willamette River CSO events from an average of 50 per year to no more than four per winter and one every third summer.

For more information contact Linc Mann, 503-823-5328.

Portland treatment plant moves toward 100% biogas utilization

News Release

March 5, 2015

The Portland City Council has approved a contract for final design of a facility at the Columbia Boulevard Wastewater Treatment Plant (CBWTP) to convert biogas into compressed natural gas vehicle fuel. Biogas is a by-product of solids treatment. This project would allow the plant to re-use nearly all of the 600 million cubic feet of biogas it produces annually.

An Environmental Services study of re-use alternatives found that the vehicle fuel option is the most economical and has the greatest environmental benefit because it will reduce diesel fuel use and cut greenhouse gas emissions. Environmental Services is exploring several possible uses for the fuel including selling it to a utility company, selling to Portland area garbage haulers to fuel trucks, fueling city vehicles, or fueling trucks that haul biosolids for land application.

It would cost an estimated $10.9-million to design and construct a biogas processing and storage facility and a vehicle fueling station at the CBWTP. Environmental Services is exploring available grants and financial incentives to help reduce project costs. Construction could start early next year and the facility could be operational by 2017.

“Biogas is a sustainable, renewable energy source,” said Portland City Commissioner Nick Fish. “This project will reduce our reliance on fossil fuels, reduce greenhouse gas emissions and save money for our sewer ratepayers.”

The CBWTP has been moving toward 100 percent biogas re-use for years. More than 30 years ago, Malarkey Roofing Products© began purchasing biogas to power part of its manufacturing facility, and currently purchases about 20 percent of the CBWTP’s biogas. The CBWTP uses another 20 percent to fuel boilers that produce heat for buildings and the solids treatment process.

In 2009, the CBWTP installed two 850-kilowatt engine-generators that use about 40 percent of the plant’s biogas as fuel to generate electricity for the wastewater treatment process. Converting biogas to vehicle fuel will re-use practically all the biogas the treatment plant produces.

Bridlemile School Sewer Overflow

Sanitary Sewer Overflow Update

February 23, 2015

City maintenance crews responded to a reported sewage release on Saturday, February 7, 2015 at Bridlemile Elementary School, 4300 SW 47th Avenue in Portland. Crews found sewage flowing from a manhole on the school grounds at 1:24 p.m. and cleared roots from a blocked sewer pipe to stop the release at 2:30 p.m.

From the time maintenance crews confirmed the release to the time they stopped it, an estimated 6,600 gallons of sewage overflowed from the manhole. Some of the sewage flowed into a catch basin on school property. The catch basin is connected to a pipe that drains to Fanno Creek. Crews applied lime to the area to kill bacteria and placed warning signs at the site as a precaution. Staff removed the warning signs two days later.

Environmental Services issued a news release on February 7 stating that all the sewage released had apparently soaked into the ground. City staff investigating the release were unaware of the nearby catch basin until notified two days later by the citizen who initially reported the sewage release. The catch basin is privately owned and doesn’t appear on city maps.

The original news release also reported that the estimated volume of the release from the time maintenance crews verified it until they stopped it was 5,600 gallons. Staff investigating the release later revised that estimate to 6,600 gallons.

Innovative Wet Weather Program video profiles creative green infrastructure projects

News Release

January 8, 2015

A U.S. Environmental Protection Agency (EPA) Innovative Wet Weather grant program has funded 37 public and private projects throughout Portland that demonstrate how different kinds of green infrastructure can effectively manage stormwater. Environmental Services has produced a video (http://vimeo/portlandbes/iwwp) that profiles some of the innovations the program funded.

Green infrastructure uses vegetation to slow, retain and filter stormwater. Between 2002 and 2014, $3.4 million in EPA grants funded projects that demonstrate sustainable, low-impact stormwater management solutions. The program funded a variety of green infrastructure projects including green street planters, rain gardens, vegetated swales, pervious pavement and ecoroofs.

Managing urban stormwater runoff with green infrastructure protects rivers and streams, replenishes groundwater, and contributes to healthy watersheds. Green infrastructure can also make sewer and stormwater pipe infrastructure work more efficiently and reduce the need for more expensive pipe solutions.

In addition to managing stormwater, the green infrastructure projects the EPA grants supported have many other benefits including calming traffic, providing bicycle parking space, and enhancing neighborhood livability.

Projects the Innovative Wet Weather Program grant supported include:

Mississippi Commons Stormwater Planter
The Mississippi Commons development installed a stormwater planter in 2004 when sustainable stormwater management and green infrastructure were new concepts for site development. The project introduced several innovative and artistic stormwater management approaches. The stormwater planter integrated into the design of the commercial space manages 340,000 gallons of roof runoff annually.

SE Clay Green Street – Route to the River
The city worked with the community on the SE Clay Green Street Project from the Willamette River to SE 12th Avenue. The project gives inner east side Portland residents improved and safer connections to the Willamette River and an urban greenway through the Central Eastside Industrial District. The green street planters remove about two million gallons of stormwater runoff annually from Portland's combined sewer system. The project also maintains freight and business activities, enhances pedestrian and bicycle access to the Willamette River, and improves watershed health.

Stormwater Education Plaza
Environmental Services worked with Portland Community College (PCC) to combine green stormwater management with an interpretive exhibit and public art in the Central Eastside Industrial District. The rain garden at PCC’s CLIMB Center for Advancement manages stormwater from the roof and adjacent street and a green roof on the interpretive kiosk absorbs rain to reduce runoff. This project manages over 120,000 gallons of stormwater annually.

Stormwater Bike Corral
Rain from this sculpture and covered bike corral at NE Dekum and Durham drains to a green street planter that manages 65,000 gallons of stormwater annually from streets and an adjacent building. Artists Peg Butler and Buster Simpson used oil industry imagery in the project design because the facility replaced vehicle parking with bike parking and vegetation. Ecoroof planters are halved oil barrels with iridescent surfaces that change hues much like oil sheens.
