[1] The Sullivan Pumping Station, when constructed beginning in 1951 as part of an overhaul of the city's sewage system, became the largest component of the city's sewage system.

It was across the Willamette River from the Ankeny station, in the block bounded by NE Everett, Flanders, 2nd, and 3rd streets.

(These streets no longer exist; the location at the mouth of Sullivan's Gulch is now a railroad interchange.)

The Ankeny station served to pump sewage under the river to the Sullivan's Gulch plant, which in turn transferred it to a massive plant on Columbia Boulevard for treatment prior to being dumped into the Columbia River.
