WHITING, Iowa – The mysterious clay tile line that was discharging into the McCandles – Cleghorn ditch and reported to the DNR on Friday, July 13 has since been identified.
After dye testing, using a camera in the unknown line, and dirt work, it was determined that a 10-inch clay tile line had collapsed under the city of Whiting’s wetland. The tile was likely installed in the mid 1900's and had been abandoned. The tile was exposed and then removed. At the end of the exposed tile, a 10-inch air bladder was installed to cap off the line. Clay was then added to fill in the area near the capped tile line.
Now that the discharge has been stopped, the City of Whiting is working to restore the wetland to the originally designed standards.
