Follow that flush: Dubuque invited to tour updated wastewater plant

Posted: Updated:

Every time somebody flushes a toilet or turns on a sink in Dubuque, that water goes to the newly-renovated Water and Resource Recovery Center.

The facility serves nearly 23,000 households and commercial and industrial customers, treating close to 10 million gallons of wastewater each day.

On Thurs., Oct. 3, the city is inviting the public to tour the updated facility, starting with a ribbon-cutting ceremony at 5:30 p.m.

Formerly known as the Water Pollution Control Plant, the facility underwent a three-year, $65 million upgrade. That's the city's largest capital improvement project ever.

The Water and Resource Recovery Center features anaerobic digestion for wastewater sludge stabilization and energy recovery in the form of methane, feeding into the city's sustainability and energy-reduction goals.

The city says the plant will be able to generate some 50 percent of its electrical energy needs on-site using the recovered methane. In the future, the city hopes to bump that to 100 percent.

"Other sustainable improvements include improved efficiency in the aeration system to reduce energy use, ultraviolet light disinfection to replace chemical disinfection with chlorine, low- and no- maintenance landscaping, rain gardens for on-site stormwater management, and implementation of Energy Star design guidelines for the numerous buildings on site to reduce lighting and HVAC energy requirements," the city's website says. "In addition, the 9,000-sq. ft. administration building is heated and cooled year-round with the plant's treated water prior to discharge to the Mississippi River."

The facility is at 795 Julien Dubuque Drive.

Parking for the Oct. 3 event will be on the south side of Julien Dubuque Drive. Overflow parking will be available in the Dubuque Girls Independent Softball Complex parking lot with shuttle service to and from the event.
