ST. LOUIS - The heavy rain we've seen over the past few days usually means a lot of storm water run-off in the sewer system. That can lead to water backing up into homes and businesses.

The Metropolitan St. Louis Sewer District has now has found a beautiful way to fix that problem with areas they call rain gardens. The goal of Project Clear is to improve water quality, but the landscaping of plants, flowers and boulders also helps control the extra influx of water.

MSD says it's working. Last April, over a two day period, the St. Louis area saw between two and five inches of rain. MSD reported 150 overrun sewer mains.

Compare that to April of this year when two to six inches of rain fell over two days, with only 53 overrun sewer mains. That's a 64-percent decrease.

MSD is looking into creating more rain gardens that can be installed across the area.
