Permits

Prior to the start of work, permits are required for the construction, repair, adjustment, rodding or cleaning of any subsurface structure designed to collect or transport storm and/or sanitary waste water, either on private property, or in the public way. Permits can ONLY be obtained by a LICENSED DRAINLAYER. A licensed Drainlayer is a person possessing a current Sewer and Drain License issued by the City of Chicago. Evidence of a current City of Chicago general business or home repair license and a Department of Transportation Public Way Work License must be presented at the time of application for a Drainlayer’s License.
