All storm pipes must conform to Chapter 2, Section 4 of the Urban Design Standards for Public Improvement Manual as well as any Sioux City supplement to the manual. Before using any type of plastic pipe it shall be the responsibility of the consumer or installer to verify the absence of any contaminated soil which may negate the option of PVC or polyethylene pipe.
