Construction, installation or modification of any wastewater disposal system including sanitary sewer extensions requires a construction permit issued by the Department. Review of applications for construction permits shall be based on the criteria contained in the "Iowa Wastewater Facilities Design Standards," the Ten States Standards, applicable federal guidelines and standards, standard textbooks, current technical literature and applicable safety standards. To the extent of any conflict between the above criteria the "Iowa Wastewater Facilities Design Standards" standards shall prevail (567 IAC 64.2(9)).
A construction permit shall not be required for storm sewers or storm water disposal systems that transport only storm water, any new disposal system or extension or addition to any existing disposal system that receives only domestic or sanitary sewage from a building, housing or occupied by 15 persons or less.
Applications for a construction permit must be submitted to the Department at least 120 days in advance of the date of start of construction. The Department will issue a construction permit within 60 days of receipt of a complete application or denying the construction permit in writing unless a longer review period is required and the applicant is so notified in writing. The construction permit shall expire if construction has not commenced within one year of the date of issuance thereof. The Department may grant an extension of time to commence construction if it is necessary or justified.
Applicable rules for wastewater construction permitting are located in
Chapter 567 IAC 64 of the Iowa Administrative Code. The current Iowa Wastewater Facilities Design Standards are located on the Design Standards Webpage.
