  • Urban stormwater could release contaminants to ground, surface waters

    A good rainstorm can make a city feel clean and revitalized. However, the substances that wash off of buildings, streets and sidewalks and down storm drains might not be so refreshing. Now, researchers reporting in ACS' Environmental Science & Technology have analyzed untreated urban stormwater from 50 rainstorms across the U.S., finding a wide variety of contaminants that could ...

  • How to Reduce Stormwater Infrastructure with Porous Pavers

    Porous pavement solutions have drawn considerable interest in communities for the green engineering benefits they provide. Grass and gravel porous pavers can greatly reduce stormwater runoff by enabling a high infiltration or percolation rate of water into underlying soils. The permeability of these systems can also trap suspended solids, thus filtering them out of any residual runoff so water ...

  • Soil compaction, the invisible threat to agriculture.

    Subsurface densification of the soil occurs when the load-bearing strength of the soil is exceeded. In the layer just beneath the plough, densification can occur; this plough sole begins at a depth of about 30 cm. Over time, the soil will lose its structure and its pore will disappear. This threat might be invisible from the surface, but it can be measured! Disrupting water management In case of ...

  • Flooded streets, normal or manageable

    One of the challenges for urban planners is urban water management. For example, buildings and paved roads prevent natural infiltration and direct the water flow to channels and sewers. Moreover, the weather patterns are also changing. We are increasingly faced with longer periods of drought and short periods of intense rainfall. Water drainage and sewage system Because the ...

  • Drening for Stormwater Management at Orio Al Serio Airport in Bergamo

    The parking lot of Orio al Serio Airport in Bergamo has recently been affected by expansion works which allowed to add 1500 car parks to the other 1500 already existing ones. Paving a large ground surface is an intervention that affects rainwater’s natural infiltration into the subsoil, with the consequent risk of floodings and damages to ...
