Wastewater Permits Program

MDE’s Wastewater Permits Program (WWPP), within the Water Management Administration, issues permits to protect Maryland’s water resources by controlling industrial and municipal wastewater discharges.  Surface water discharges are regulated through combined State and federal permits under the National Pollutant Discharge Elimination System (NPDES).  Groundwater discharges are regulated through State issued groundwater discharge permits.  Also related to the protection of groundwater is the WWPP coordination with all local health departments for the regulation of individual wells and septic systems.


The discharge from municipal wastewater and water treatment facilities to surface and/or groundwater.


These are permits issued to industrial facilities that discharge to surface and/or groundwater. Industrial, commercial or institutional facilities that discharge wastewater (or stormwater associated with industrial activities) to surface waters of Maryland may need one of these permits.
