What's New

1. Wastewater Design Standards Update

The Iowa Wastewater Facilities Design Standards were adopted in the late 1970s and early 1980s. The Iowa DNR has initiated a review of selected Chapters and revisions have been proposed. Please continue to the design standards update webpage.


2. Alternative Wastewater Treatment Design Guidance Manuals

The DNR has developed design guidance manuals for five technologies in an effort to broaden the number of treatment options considered for managing wastewater within Iowa's communities (with populations ranging from 25 to 250) and provide uniform design guidelines for everyone involved to follow. Please continue to the design guidance manuals webpage.

The Wastewater Construction Section issues wastewater construction permits. Permits are required for the construction of any municipal and industrial treatment and collection facilities that discharge treated wastewater to a river or stream. This section also reviews and issues construction permits for wastewater reclamation projects and non-discharging animal feeding operations. Wastewater construction permits are required for small on-site wastewater disposal systems that commonly serve developments or small areas in the treatment of domestic wastewater. Some larger cities have accepted delegation of responsibility for the review of sewer extensions.

Finally, the section administers the Wastewater State Revolving Fund Loan Program offering communities and sanitary districts low interest loans for the construction of wastewater treatment and collection system improvements.
