We use water in so many ways: drinking, irrigating farms, hydropower, recreation, disposal and treatment of sewage, and much more. In New York we receive approximately 40 inches of water a year. In our region much of that water will end of in the Hudson River, because we live in the Hudson River watershed. Once in the river, it might end up in our sinks or in the Atlantic Ocean (or both!). A significant amount of the rain that falls will also evaporate right back up to the sky, often through plants.
There are 2 important aspects of water for us to think about. The first is to consider where our tap water comes from. All 3 schools receive Village water, which is treated from the Hudson river. This water does not return to the Hudson river immediately: the wastewater fills septic tanks located at each school.
The other consideration is to understand where precipitation goes that falls on our schools. Water that falls on forests and fields mainly permeates into the ground and replenishes groundwater. Water that falls on impermeable surfaces like parking lots or roads lead to increased runoff—a common source of pollution in our rivers.
