open skip for general waste for Meadowfield Durham.
Its total cap system required 260,000 cu yd
of fill material.
The volume of sand required, 300,000 cu yd, coupled with strict aesthetic requirements, made hydraulic dredging the only economically feasible option.
The dredge pumped up to 100,000 cu yd of material per day.
Regrading and flattening of the steep east slope would have required the removal and disposal of a large quantity of refuse (over 100,000 cu yd
to achieve 4H:1V) or the import of the same quantity of granular fill.
The Lamb Canyon project required the removal and disposal of approximately 2 million cu yd
of excess dirt at significant expense.
The baling operations resulted in over 200,000 cu yd
of metal being recovered and removed from the island for eventual recycling.
