70 ILCS 2405/23.7
For purposes of this Act, territory to be organized as a sanitary district shall be considered to be contiguous territory, and territory to be annexed to a sanitary district shall be considered to be contiguous to the sanitary district notwithstanding that the territory to be so organized is divided by, or that the territory to be so annexed is separated from the sanitary district by, one or more railroad rights-of-ways, public easements, property owned by a public utility, or property owned by a forest preserve district or any public agency or not-for-profit corporation, provided that the property does not require sanitary sewer service. However, upon such organization or annexation, the area included within any such right-of-way, public easement, property owned by a public utility, or property owned by a forest preserve district or any public agency or not-for-profit corporation shall not be considered a part of or annexed to the sanitary district and shall not be subject to rights-of-way for access or services without the approval of the legal owner of the property.
