PORTLAND, Ore. (KOIN) — The Portland Bureau of Environmental Services said the 27,000 gallons of sewage that spilled into a creek on Sunday was from a privately-owned pipe and not a city sewer line.

The Oregonian/OregonLive reported the sewage spilled into Woods Creek in the 6100 block of Southwest Canby Street. Woods Creek feeds into Fanno Creek.

The private pipe was designed to carry only rainwater to the creek. The bureau said it appears that a private sewage pipe was mistakenly connected to it, leading to Sunday’s spill.

Maintenance crews estimate 27,000 gallons spilled into the creek before they diverted the flow into a nearby sewage line.

City crews stopped the discharge on Sunday by diverting the flow to the city sewer system. Crews are still conducting a cleanup at the site adjacent to April Hill Park Natural Area trail between April Hill Park and Southwest Multnomah Boulevard.

Warning signs to avoid contact with Woods Creek remain in place as the cleanup and investigation continue.

April Hill Park and the adjacent nature trail are not impacted by the sewage spill and remain open to the public.
