A new distribution center for the United States Postal Service in Portland, Oregon required a wastewater lift station. The lift station handles both wastewater and stormwater flows because the stormwater that is collected onsite is essentially wastewater due to fuel and other contaminants from a truck loading area.

A new 144,000 square feet, two building industrial center needed a large stormwater pump station to handle the runoff from the site. This triplex system includes a fourth, “jockey” pump to handle low flow dry-season runoff. The three large pumps are 20 hp Ebara submersible pumps designed for redundant pumping during high flow events. A pressure transducer serves as the primary level-sensing device and operates inside of a perforated stilling well designed to prevent solids from interfering with the sensor. The electrical controls are configured with a logic relay, intrinsically safe circuits, and communications.
