As part of the executive design for the geomorphological and hydraulic arrangement of the Val Rogno landfill, SGAI S.r.l. studied the following interventions: extension of the spillway, extension of the road tunnel, intervention for the construction of the new bed of the Rogno stream in the open air, rolling basins and dissipators; landfill bottom preparation, construction of drainage systems and leachate control, waterproofing of the container, hydraulic arrangement of the riverbed upstream of the landfill with bridles; definitive gutter channel, construction of guard ditches for collecting water from the slopes during construction; access road to the new riverbed; metric calculations for the works to be performed; structural practices.

As part of the completion and arrangement of the Val Riso sludge accumulation, SGAI S.r.l. carried out the preliminary executive and construction design services. Specifically, the waterproofing of the bottom and the perishing of the entire landfill was carried out by injection of manchettes and plastic bulkhead with water-cement and bentonite jet grouting. Furthermore, the hydraulic regulation and environmental recovery interventions of the site were studied. Various works were designed and monitoring tests were carried out to verify the results of the intervention.
