Storm water work requires site evaluation, drainage planning, proper elevations, suitable materials, excavation equipment, and installation methods appropriate for expected runoff conditions. Contractors must consider existing drainage patterns, soil characteristics, property slopes, nearby structures, paved surfaces, underground utilities, and available discharge locations. Project plans and local requirements may also determine specific system components needed.

Installation may involve excavation for pipes, catch basins, inlets, drainage structures, swales, or underground systems. Proper bedding, pipe connections, grading, backfilling, and compaction help support reliable performance. After installation, disturbed areas should be stabilized and finished appropriately so water can move through the intended drainage system effectively.
