Today I completed extensive storm drain maintenance on a commercial property's drainage system. I began by using high-powered water jetting equipment to clear accumulated debris from the main storm drain lines, removing several years of sediment buildup. I discovered root intrusion in two sections of pipe, which I cleared using specialized cutting heads. After cleaning, I performed a video inspection of all storm drain lines to document their condition and identified three cracked pipe sections requiring future repair. I also cleaned all catch basins, removing leaves and debris, and tested the drainage flow rate to ensure proper water evacuation during heavy rain conditions.
