What kind of stormwater quality problems currently exist in Normal?
The primary problem that Normal is attempting to address with the stormwater management program deals with contaminants that are deposited into our drainage system by stormwater runoff. These contaminants (a common example is yard fertilizers), ultimately accelerate the erosion of our drainage system infrastructure. Infrastructure refers to the physical components of the drainage system, such as pipes, stream banks and detention ponds. Erosion of our pipes, streams, detention basins, culverts and other components of the drainage system ultimately decrease the effectiveness of our drainage system and leads to costly system maintenance issues.
