“Rewetland - Widespread Introduction of Built Wetlands for a Wastewater Treatment of Agro Pontino” (http://www.rewetland.eu/life/) was a project funded by the European LIFE program and took place in the area of the province of Latina between 2010 and 2014.
The program involved the entire network of reclamation canals, aiming to reduce surface water pollution through widespread phytoremediation techniques, with the creation of buffer strips along watercourses, filter ecosystems and artificial wetlands.
In particular, UPPER has collected the experience of the pilot intervention carried out within the Circeo National Park (partner of both projects), i.e. the creation of a filter ecosystem.
Through the planting of herbaceous and shrubby plant species of a marshy environment, i.e. capable of withstanding soils saturated with water for several months a year, the water phytoremediation process has been put in place, i.e. the chemical- physical one which already occurs in the nature in marshy areas and which allows the rebalancing of the natural cycles of nutrients (carbon, nitrogen, phosphorus, etc.) through the action of plants.
In this way, the new plantings supported a strip of reeds already present on the shore of Lake Fogliano, allowing the polluted waters from the Rio Martino - Foce Verde canal to regenerate, to enter the partially purified area of Fogliano Lake.
All the data collected during and at the conclusion of the REWETLAND project have been useful for UPPER in monitoring the effectiveness of constructed wetlands and the costs they entail, as well as in their long-term management. Purification activities are in fact envisaged for UPPER activities relating to city channels.
Another point of contact was the experience of REWETLAND with databases for the collection and organization of all monitoring data in the areas of territory subject to the interventions. For this purpose, WebGIS, a geographic information system that allows people to georeference and interpret the data collected, and GEOBLOG, an interactive platform to allow users to enter comments and proposals, were created.
The created geo-database was the basis for the development in UPPER of WHiP, the open source platform elaborated by the Territorial Planning Laboratory of Ce.R.S.I.Te.S (Sapienza University of Rome) with the aim of favoring the user interaction both in the co-design of the UPPER areas and in the information and implementation of the project results.
A further experience borrowed from the REWETLAND project was certainly the shared management of interventions on the territory.
As reported on the reference site, “the project tackled the problems by adopting participatory management of the water system. The sharing of choices with all the actors involved in territorial management (institutions, bodies, farmers and citizens) and the inter-institutional collaboration between the bodies responsible for programming, planning and implementing the interventions have been essential to ensure their effectiveness and achieve sustainability goals."
A configuration of good practice also found in other completed projects or still in progress.
