Stormwater (Water)

Runoff water from storms needs to be clean of debris and pollutants so that drinking water and waterways are clean for all.  This can be achieved by appropriate Stormwater Management.   In March 2020, The Department of Environmental Protection formally adopted groundbreaking amendments to the state’s stormwater management rules to better protect water quality by reducing polluted runoff through implementation of  required green infrastructure technologies for major developments.  As of March 2021 all municipalities must adopt new stormwater management ordinances to incorporate these changes.

Plant uptake and evapotranspiration account for about 40 percent.
