Our Facilities

We collect and treat an average of 41 million gallons a day (mgd) from the Green Bay Facility (33 mgd) and De Pere Facility (8 mgd), removing more than 97 percent of its pollutants.

Dye Testing 2023Dye testing

From time to time, NEW Water conducts dye testing as part of optimization efforts for critical systems that allow our community to use our services, around the clock.

Dye testing is a common practice for wastewater, water, and storm water management. It can determine where flow is coming from, where it is going, and help ensure systems are functioning properly. It also can help detect optimization opportunities within pipes and other wastewater infrastructure.

The dye used is nontoxic, biodegradable, and environmentally friendly.

Safety Flare

From time to time you may see a flare at NEW Water’s Green Bay campus, which safely burns biogas that we are not using to create our own energy, as part of our Resource Recovery & Electrical Energy (R2E2) facility.


Watch R2E2: A NEW Era in Resource Recovery

Green Bay Facility

The Green Bay Facility was built in 1975. It was the first wastewater treatment facility in the country to treat both municipal and paper mill waste. Recently, the Green Bay facility replaced the old solids building with a new solids handling facility called the Resource Recovery and Electrical Energy generation system, or R2E2.

The Green Bay Facility is located on the mouth of the Fox River and services the majority of NEW Water’s service area including the City of Green Bay. On average the facility receives about 41 million gallons per day of wastewater from 15 surrounding communities.

De Pere Facility

Since January 1, 2008, NEW Water has operated the De Pere wastewater treatment facility. The De Pere Facility services our southern service area, primarily the City of De Pere, parts of the Village of Ashwaubenon, and parts of the Towns of Lawrence, Bellevue, and Hobart.

Built in 1976, the De Pere Facility has been upgraded over the years to best meet the needs of the community. The De Pere facility uses an ultraviolet light disinfection system that is capable of treating 15 mgd which is a unique feature of the De Pere facility. The average flow received at the facility is 8 million gallons per day (mdg). The maximum design flow for the facility is 14.2 mgd, with a maximum wet design flow of 30 mgd.

Resource Recovery & Electrical Energy (R2E2)

NEW Water's solids handling facility is called the Resource Recovery and Electrical Energy, or R2E2. Construction launched in 2015, and is currently online. NEW Water replaced its solids handling facility to meet stricter environmental regulations, address the needs for increased capacity, and to replace aging infrastructure. Using anaerobic digestion and other technologies, the facility produces electricity, as well as recovers heat.  R2E2 represents a change in philosophy by valuing waste as a resource to recover, rather than something to dispose. R2E2 will allow NEW Water to continue to provide the safe, reliable, around-the-clock service the community has come to expect. 

At the present time, NEW Water is not producing struvite. During the commissioning phase of the new solids facility, it was determined that the struvite recovery process was no longer needed. This may change in the future, and NEW Water will continue to search for other opportunities for resource recovery.
