Wastewater 101

District Educator Kristie Munson had the unique opportunity to tour the East End wastewater treatment facility in Portland. Kristie was thrilled to see this vital infrastructure in action and learn more about how the facility works.

The Portland wastewater facility actually produces two end products: millions of gallons of clean water, which flow in Casco Bay, and hundreds of tons of treated biosolids.  Portland’s wastewater treatment facility is Maine’s largest. Eleven pumping stations located around the city help to move wastewater to the facility. Since first opening in 1979, Portland’s facility has been expanded and modified in order to handle more wastewater and provide additional protection to Casco Bay.

In fact, the Portland facility is key to protecting the entire Casco Bay watershed. Four million tons of septage from private septic systems in Naples, Casco, Bridgton, Yarmouth and others are received for treatment every year.

Yes, Maine’s largest wastewater treatment facility is working efficiently and effectively to keep our water clean, safe and healthy. You can even see that for yourself, because right around the corner from the facility is Portland’s East End Beach, which is once again safe for swimming and boating. And just on the other side of the Eastern Prom, Back Cove has become a popular place for exercise and recreation. (Portland Water District)
