The ice storm has caused problems for the Louisville Metro Sewer District.MSD Director Bud Schardein says fifty pumping stations that keep water from accumulating lost power in the storm.“We either have them on generator or we’re pumping with tanker trucks," he says. "The whole idea and the objective is to keep those stations pumping down so it doesn’t back up into people’s homes, basements, that sort of thing.”Schardein says there’s also a risk of water accumulating on streets.“Water can’t get into the basins, so we’ve got about 21 crews on the street today and we’ll be running them, we have through the night, and we’ll be running them all day and night tonight, making sure we can keep those catch-basins open making sure that melting water, melting ice can get in," he says.Mayor Jerry Abramson says he has alerted state officials about water pooling on interstates.
