|Lids for settlement tanks
|As part of its site operating plan, CEMEX’s Borough Green Landfill has to provide a vehicle wheel wash which recycles all water without discharge.
To allow free flow of water and silt, the settlement tanks were placed into the ground, but this presented obvious safety issues. As an alternative to handrails – which could not guard against incidents outside of working hours – CEMEX installed three weld mesh lids on rails which were both transparent for operational reasons and strong enough to support pedestrian traffic. When the tanks need to be emptied, padlocks are removed and the lids are moved back and forth to enable the removal of the material in each compartment.
