Septic tank
While a properly maintained and located septic tank does not pose any more environmental problems than centralized municipal sewage treatment, certain problems can arise with septic tanks in unsuitable locations. Since septic systems require large drainfields, they are not suitable for densely built areas.
Newtown Creek Wastewater Treatment Plant
The Newtown Creek Wastewater Treatment Plant is the largest sewage treatment facility operated by the New York City Department of Environmental Protection. Since 2010, its eight metallic "digester eggs," which are 140 feet (42 meters) tall and dramatically illuminated with blue light at night, have made it a local landmark, particularly to motorists on several nearby roadways in the New York City boroughs of Brooklyn, Queens, and Manhattan. It is located on the Newtown Creek in Brooklyn's Greenpoint neighborhood along Greenpoint Avenue.
