Clean-up works — ODP — SysTraitementEauxUsees

A clean-up work is a work designed to reduce or even remove any undesirable substance from an effluent. The clean-up works are divided into two main families: wastewater treatment systems (= sewage treatment plant) and by-product treatment units. The clean-up work remains the same (same identifier) regardless of the importance and nature of the work carried out there (change of capacity, reconstruction, etc.). There will be a change of station only if there is a relocation of the station or a change in the nature of the contracting authority. The description of these two families of clean-up works is under the responsibility of the Water Agencies and the ADEME respectively.
