During the initial production of the SWMP, we identified the need to remove over 20,000m³ of classified hazardous arisings from site, working closely with our waste subcontractor, SITA, and the Environmental Health Departments of Wiltshire and Hampshire, we were able to re-classify the material as inert and transport to a local tip as capping material.
