Public Water Supply Construction Permits

NOTE: We are receiving construction permit applications, plans, specifications, and other engineering documents submitted electronically. Electronic submissions are encouraged as it will minimize steps and lag-time in our project intake process. Electronic signatures are acceptable and original signatures are not required, until further notice.

  • New applications: Submit all new water supply construction permit applications, including plans and specifications, to this email address (note the hyphen): watersupply-engineering@dnr.iowa.gov. Please note: construction permit application schedules must be sent as pdf attachments. Plans and specs under 25 MB may be sent as pdf attachments. For plans and specs larger than 25 MB, send as ZIP files or use other options for submission. Mail the construction permit fee and Schedule 1c as indicated below. No need to mail in hard copies of other schedules or plans and specs.
     
  • Projects with previously assigned project manager: Email all documents directly to the project manager if you are already working with them on a project: engineering reports, construction permit applications including plans and specifications, addenda, and change orders. If you’re unsure of the project manager, ask taroon.bidar@dnr.iowa.gov or gabe.lee@dnr.iowa.gov.

Mail the Water Supply construction permit fees and Schedule-1c to the Wallace Building address:
Iowa DNR, Attn: WS Engineering Section, 502 E 9th St, Des Moines, IA 50319-0034.
Contact Taroon Bidar if you have questions on electronic submittal at taroon.bidar@dnr.iowa.gov.


Construction Standards for Public Water Supplies

The construction standards for a project at a public water supply are the Ten States Standards as adopted through 2012, the American Water Works Association (AWWA) Standards as adopted through 2016, and 567 of the Iowa Administrative Code (IAC) subrules 43.3(7) to 43.3(9). To the extent of any conflict between the Ten States Standards and the American Water Works Association Standards and IAC 567--43.3(7) to 567--43.3(9), the Ten States Standards, IAC 567--43.3(2), and IAC 567--43.3(7) to 43.3(9) shall prevail.


Permit Description

A public water supply construction permit must be obtained from the Iowa DNR prior to the construction or modification of any source, treatment, storage, or distribution system of a public water supply system. To obtain a construction permit, the following must be submitted to the Iowa DNR Water Supply Engineering Section: the project's plans and specifications, the applicable construction permit application schedules, and the appropriate permit fee. A fact sheet is available to assist in determining when a construction permit must be obtained: DNR Water Supply Construction Permitting Fact Sheet.


Construction Permit Database

The Water/Wastewater Information System and Records Database, called W/Wisard, is an online database that provides public access to information related to past and ongoing water supply and wastewater construction projects. Project searches can be conducted utilizing a number of criteria, such as projects for a specific facility. Use this button to access the construction permit database:

What to Submit?

All applications for a construction permit must include the following three items:

In addition, the other forms (Schedules 2a through 16d) are required based upon the nature of the project (e.g., water mains, well construction, chemical feed, etc.).  The Water Supply Service Agreement form is required for all projects where the applicant is someone other than the supplier of the water.

Once the project is completed, the Notification of Completion of Construction form or postcard that is supplied with the permit must be submitted to indicate the project was completed in accordance with the approved plans and specifications.
