Replacing a main sewer line is a major excavation project that often disrupts public right-of-ways and connects directly to municipal utility systems. Because of the sanitary and environmental risks involved, local building departments strictly require permits and inspections before any trench can be backfilled.

With a population of around 26,920 residents, McDonough County generally runs a more streamlined permitting process than major urban hubs.

Code Compliance & Inspections

Given Illinois's cold climate, the Illinois Building Code emphasizes insulation, energy efficiency, and freeze protection for new work.
