• Capacity to design oil/grease separators, water quality wells.
• Capacity to design ponds (in series and in parallel) for surficial retention/storage of urban runoff.
• Capacity to design ponds for quality control of urban runoff.
• Ability of using multi-criteria analysis for the selection of appropriate BMP.

General Skills:
Autonomous work
Respect for the natural environment

Working in an interdisciplinary environment

Course Content: 

1. The Science of Ecological Engineering, Definitions. Description of urban areas pollution. Production processes, type and sources of urban runoff pollutants.
2. Quality runoff and pollutant loads estimation methods. Estimation of the pollutant accumulation on the road. Estimation of the accumulated pollutants flushing by the rain.
3. Best Management Practices (BMPs) to control the urban runoff pollution. Source control measures: roads and impervious surfaces cleaning, pervious surfaces control.
4. Filtration constructions: porous pavements, infiltration trenches, wells sewage with filtration, filters.
5. Increase surficial retention: storage on roofs and terraces.
6. Grass filters. Environmental corridors.
7. Before entering the sewer control: oil/grease separators, sewers water quality, screens.
8. Control into the sewer or the channel: channel bed stabilization methods. Storage, retention into the sewer or the channel.
9. Flood control ponds (in series and in parallel).
10. Quality control ponds: first-flush infiltration, extended dry pond, wet pond, wetlands.
11. Detention ponds (in series and in parallel) for combined sewer system.
12. Runoff treatment: sand filters, biological treatment processes, disinfection.
13. Multi-criteria analysis for the selection of the best management practices (BMPs).
