Ongoing diagnosis: Management of collected/transported flows and discharges into the natural environment
Challenge
Implementation of Article 12 of the Order of 21 July 2015 relating to sanitation systems (Article 9 of the Order of 31 July 2020):
- Continuous knowledge of the functioning,
- Prevent or identify malfunctions,
- Monitor and evaluate the effectiveness of the actions undertaken,
- To operate in a logic of continuous improvement.
The 3D EAU solution
The proposed methodology relates to the permanent diagnosis required in terms of the management of collected/transported flows and discharges into the natural environment: installation of metrological equipment and treatment/analysis/evaluation of the data obtained.
1 - Field surveys
2 - Definition of a campaign of measures to be carried out
3 - Rainfall analysis
4 - Analysis of rainfall and flow data
5 - Comparative analysis
As part of the permanent diagnosis, 3D EAU provides hydraulic expertise on sites identified as "to be equipped" by the local authority, the operator and/or the service provider's design office, in order to recommend a measurement solution in accordance with the expectations of the regulations and the technical guide for implementing the permanent diagnosis published by ASTEE, which is available via this link.
