Residents of Audubon are being asked to conserve water effective immediately. Ed Mahlstadt, with the City of Audubon Public Works, said at 5:55-p.m., there was an issue with the water plant in Audubon, and until the matter is resolved, please conserve water. He said a 10-inch main coming down from the water tower that circles back toward the water plant, has a 32-inch split in it. Crews have excavated a hole and a replacement pipe is being readied to install. In the meantime, residents are asked to conserve water where possible. Mahlstadt said the water is safe, they just need people to conserve usage for about three hours.
