Read GuideLocal Project Overview
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 growing population of around 336,328 residents, Howard County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
