The Venice Port Authority takes part in numerous projects to reduce the impact of port activities on the waters of Venice and the lagoon. Major projects include:
- stormwater runoff collection;
- construction of environmentally friendly quaysides;
- the assessment of wave motion.
Stormwater runoff collection
In all the port areas directly controlled by the Venice Port Authority rainwater is collected and conveyed to a treatment plant.
The water treatment plant located in the Marittima uses filtering cartridges to retain particles and absorb pollutants (including heavy metals, nutrients and hydrocarbons): it treats up to 95% of all rainwater.
The filtering process removes oil, grease and surface foam. Once it has been filtered, the water is conveyed into the lagoon.
Implementation of an environmentally friendly quayside
The Port Authority has launched a project to assess quaysides bordering on marinas and port yards and modify them as needed. This will avoid the contamination of the lagoon as the contaminated water will be segregated from the water table.
Assessment of the wave motion
Over recent years, the Port Authority has performed several studies on the impact of shipping on the wave motion.
The aim is to understand the distribution in time and space of the wake generated by ships up to the embankments, by determining the amplitude of the wave and the direction it propagates.
