SEALING AND ENVIRONMENTAL RESTORATION OF THE XÀBIA MUNICIPAL WASTE LANDFILL

The project consists of the sealing and environmental restoration of an inert waste cell and has an approximate budget of €1,068,886.03.

It is estimated that a total of 1.4 million tonnes of inert waste has been dumped.

The main impact on the natural environment of the site where the landfill is located is that it is located next to the bed of the Gorgos River, which may affect the quality of surface water.

Another important aspect is to solve the instability of the slopes, starting from the placement of a cliff wall at the foot of the slope, since due to the slopes of the slopes and their insufficient compaction,
landslides are generated during periods of high rainfall.

The other environmental impacts resulting from the presence of the landfill, as well as those relating to the landscape, flora and fauna of the environment and others, are estimated to be of lesser comparative importance and can easily be neutralized with the restoration work carried out during the sealing and closure of the repository.

The main features of the work are:

• Movement of land of 45,000 m3 between re-profiling of slopes and removal of rubble.
• Revegetation of 30,000 m2 with native shrub species.
• Waterproofing of the landfill with:
  • 30,000 m2 of HDPE sheets.
  • 60,000 m2 of geotextiles.
  • 15,000 m2 of draining geocomposites.
