General Information

New MiWaters Permitting System & Training

  • On July 20, 2015, the DEQ's Water Resources Division (WRD) is planning to launch a new information system called MiWaters. MiWaters will be a state-of-the-art, comprehensive, Web-based permitting and compliance database. The system will replace over 25 applications and databases currently used by the WRD, some of which are over 30 years old. MiWaters will establish a streamlined electronic permitting process, allowing Michigan to fulfill federal electronic reporting requirements. The focus of MiWaters will be permitting and compliance, including National Pollutant Discharge Elimination System (NPDES), storm water, groundwater discharge, and others.
  • Upon implementation of MiWaters, paper applications for NPDES and groundwater permits will no longer be accepted.
  • Please see the MiWaters page for additional information.
