How Do You Clog a Culvert

Another method for unclogging your culvert is to use a pressure washer or sewage jetter to blast the flow-disrupting materials out with water. Equipment like this is pricy, but you may be able to borrow something from the local volunteer fire department or other municipal department such as sewage or road maintenance.

What happens when a culvert is blocked?

The consequences of culvert blockage on catchment flooding are discussed. These include increased flood levels, flow diversions out of the streams, development of unexpected overland flood flowpaths, and scouring of overtopped embankments.

How bad is a culvert?

Culverts limit the movements of migratory fish like the critically endangered European eel, disrupting their access to food and spawning areas. When fish are blocked from making these essential journeys, entire freshwater ecosystems suffer.
