The Hudson River receives most of this treated water:
The Ramapo River receives treated water from the Village of Suffern (and since 2009 the Western Ramapo Advanced Wastewater Treatment Plant)
In 2005, about 14.6 billion gallons of treated wastewater was lost from the local hydrologic system.
The “spikes” in flows from these treatment plants correspond to non-wastewater inputs associated with rainfall: inflow from storm runoff, infiltration of groundwater where the water table is high, and perhaps illegal sump pump connections to sewers. In fact, sanitary sewers are a subsurface drainage system very much like local rivers.
