Silt & Sediment Removal

What This Service Involves

Sediment collects in pipes, channels, ponds, and vaults, reducing capacity and carrying attached pollutants downstream. Our crews vactor, dredge, or excavate accumulated material depending on the structure and access. We characterize and dispose of sediment according to its contamination profile, since some stormwater sediments require special handling. Volumes removed are documented to track facility performance and disposal.

Benefits

Restored conveyance and storage capacity; contamination-appropriate sediment characterization and disposal; methods matched to each structure and access condition; documented volumes for performance tracking; reduced pollutant transport downstream

Our Process

1) Assess sediment depth, contamination, and access; 2) Remove material by vactor, dredge, or excavation as suited; 3) Characterize sediment and route it to the correct disposal facility; 4) Document volumes and restored capacity

What Affects the Cost

Sediment volume and contamination level; removal method and equipment required; disposal facility and any special handling; site access and dewatering needs; traffic control for in-street work

Best Time of Year

Removal from ponds and channels is scheduled during dry summer conditions when dewatering and access are most practical.
