Storm Drain Cleaning

What This Service Involves

Using high-pressure jetting and vacuum recovery, we clear sediment, roots, and debris from storm drain pipes and culverts to restore designed flow capacity. Blocked lines in Western Washington cause rapid street flooding during the region's intense rain cells, so proactive cleaning is a critical reliability measure for public works. We recover and properly dispose of all flushed material rather than pushing it downstream, protecting receiving waters and satisfying permit conditions. Line condition and cleaned footage are documented for your system records.

Benefits

Restores full pipe flow capacity to prevent street flooding; removes root intrusion and sediment before failures occur; recovers debris rather than displacing it downstream; supports permit compliance and receiving-water protection; documents line condition for system asset records

Our Process

1) Identify target lines and access points from system maps; 2) Set up traffic control and jetting and vacuum equipment; 3) Jet the line and vacuum-recover dislodged sediment and debris; 4) Dispose of material and log cleaned footage and observed conditions

What Affects the Cost

Pipe diameter, length, and material; severity of blockage and root intrusion; access and manhole spacing; recovered-material disposal costs; traffic control and confined-space requirements

Best Time of Year

Storm drain cleaning is best performed in late summer through early fall so conveyances run clear when Puget Sound's peak-intensity storms arrive.
