Scientific problems:

Sediments Operational goal: managing sediments, and reducing wastes

(i.e. European framework on wastes)

Compared with literature data

(stormwater sediments from different

devices/locations)

18 infiltration basins

Context: urban stormwater basins accumulate sediments, which need to be adequately managed

– What are the

characteristics of urban stormwater sediments?

– Is this material similar

to other sediments or

urban soils, or is there a

specificity?

→ DESIR project – towards the identification of sustainable management pathways for urban stormwater sediments

1. Summary of knowledge on urban sediments 2. State of the art of management methods 3. Interview of practitioners

4. Treatment/valorization: state of the art only

Objectives of DESIR program
