Sotavento Landfill

During the construction process, various large-scale works were carried out, such as: clearing, earthworks (excavations and embankments, waterproofing and accessories), drainage, water supply network, electrical network installation, paving, and landscaping.  

The aforementioned works were essential to successfully complete the project; however, to clearly understand the project's depth, it is necessary to explore the following specifics: 

-Clearing and stripping of the intervention area; 

- Earthworks to shape the terrain for the confinement cell; 

-Implementation of the environmental protection system (waterproofing) of the base area, slopes and embankments, consisting of: 

.Passive Barrier - a 0.50 m layer of silty-clay soils, reinforced on top with bentonite geocomposite; 

.Active Barrier - at least 2.0 mm thick HDPE geomembrane, protected on top by non-woven geotextile in the base area of the cell; 

.In the base area – a 0.50 m drainage mineral layer; 

-Leachate drainage system; 

-Rainwater drainage system; 

-Subsurface water drainage system; 

-Cell degassing system; 

-Access and circulation road around the confinement area; 

-Fire network; 

-Service network; 

-Groundwater monitoring system; 

-Rainwater drainage network; 

-Electricity distribution and lighting network.
