If an incident occurs during normal business hours, Monday through Friday, 8 am to 5 pm, please contact the Utilities Department at 515-963-3520. If it is after business hours, contact Polk County Dispatch at 515-286-3333, option 5.
If water / sewage is coming up in your basement (or any other drain), City crews will be out to check the City's lines. If the City sewer is flowing freely, you may have a blockage in your service line. If that is the case, you will have to contact a plumber to have your service line unclogged.
