Wastewater Permit Information Exchange System (WWPIE)

WWPIE provides public access to individual NPDES (National Pollutant Discharge Elimination System) permits for the State of Iowa.  In WWPIE, you may search for individual NPDES permits, such as city or industry wastewater permits, by proceeding to the search page.  General Permits Nos. 1 - 7 are not included in WWPIE and facilities covered by these permits will not appear in the search.  Only final and draft individual NPDES permits are included in WWPIE.  Expired, closed, or revoked permits are not searchable.  If you wish to obtain information on any permit not included in WWPIE, please contact a permit writer listed in the NPDES Staff Roster.

WWPIE allows persons interested in NPDES permitting to register, save searches, and comment on draft NPDES permits.  In addition, NPDES permit holders or their designees can register and apply for new or renewals of individual NPDES permits in WWPIE.  Please view the WWPIE User Manual or the FAQ document in WWPIE for more information on registering in WWPIE.
