Many commercial projects that take place out in the county without the infrastructure of municipal water, power, and sewer will require extra and special consideration.  If the building requires sprinkler systems, water containment may be  an issue.  Wastewater management on commercial and industrial projects can require IDNR approval above what the County Environmental office can issue. This can be a lengthy process and could require engineered design drawings for the well and wastewater layouts depending on the building type and usage.
