Finding a balance between wetlands and water treatment

Take a stroll through the Wakodahatchee Wetlands and you'll likely spot great blue herons, like the fluffed-up pair we're featuring today. Located in Delray Beach, Florida, the park first opened to the public back in 1996. A lengthy boardwalk takes visitors over ponds and through marshes, offering the chance to see more than 150 bird species, plus turtles, fish, frogs, alligators, and other Floridian fauna. Every day, the Palm Beach County Water Utilities Department pumps about nine million litres of highly treated wastewater into the wetlands. Then the algae and other plants naturally finish the purification process before the water seeps back into the water table. Quite an upgrade from a yucky wastewater pond.
