Dyed Water Testing

The Public Works Department is continuing an ongoing program to identify locations where storm water is entering the Village sanitary sewer system. Dye flooding is a technique that is used to pinpoint those wear leaks are occuring so that locations can be repaired. For this effort, storm sewers adjacent to sanitary sewers are filled to capacity with dyed green water, using a non-toxic fluorescent dye. At peak flooding conditions, cameras are inserted into the sanitary sewer and are used to televise the locations where green dyed water is observed flowing into the sanitary sewers. 

Residents may observe some remnant green dye in the street curb-line, in the storm sewers, or at storm sewer outfall locations. This non-toxic dye will dissipate fairly quickly and will not stain the ground nor harm any vegetation.
