D1: depositing waste from dredging inland waters

Read New rules from January 2027 to find out what to do.

Dredging spoil means waste you produce from dredging inland waters. It includes plant matter. 

Your waste must fit within the waste code and description.

Types and amounts of waste you can deposit

(*) An asterisk at the end of a code means the waste is hazardous.

You can deposit, screen and de-water up to 50 cubic metres of dredging spoil on each metre length of land during any 12-month period. 

This also applies to dredging spoil you put in a container or lagoon.

You must deposit the dredging spoil at the closest possible point to the location of the dredging.

This would be either on the water’s edge or the closest point where you can deposit the spoil in one mechanical operation.

The ‘closest possible point’ allows for things that might prevent you from depositing the spoil closer to the dredging point, for example: 

After you’ve deposited, screened and dewatered the dredging spoil, you can spread it on the adjoining land immediately next to the inland water.

If you want to transport the dredging spoil to spread or use elsewhere, you’ll need separate exemptions or permits.

If you put dredging spoil in a container or lagoon under a D1 waste exemption, you must remove any containment structures when the dredging spoil has dried out, or before you spread it on adjoining land.
