Sewage pumping plant, #4 (Fries Avenue Plant). Wilmington, Los Angeles. Although most of the sewage collected in the city travels via gravity to one of the four main sewage treatment plants, occasionally pumping plants in low-lying areas were built to raise the level of the sewage so that it can be carried to a treatment plant.
