9. Take a Tour of the Digester Eggs at the Newtown Creek Wastewater Treatment Plant

What’s more romantic than sludge and wastewater treatment? This annual tour at the Newtown Creek Wastewater Treatment Plant Digester Eggs is extremely popular and always a hoot. We took it last year, and you get a great overview of the process by NYC Department of Environmental Protection staff that work at the plant and get to head up to the glass walkways of the award winning eggs to get a great view of Brooklyn and Manhattan.
