Treatment Plant Falls is a large and powerful 25-foot waterfall along the Passaic River in Little Falls and Totowa. While the waterfall is man-made and created through water diversion, the waterfall looks extremely natural as it plunges down basalt cliffs.
The waterfall can be viewed from across the Passaic River from the run-down Morris Canal Park.
Despite being located in the town of Little Falls, this waterfall is significantly more impressive than Little Falls itself.
