The 1998 count was 4,137 cbs. We removed almost 100 yards of debris from these cbs. To illustrate these amounts, a large wheelbarrow holds 4 cubic feet. The debris removed from cbs would fill 675 wheelbarrows. We also have a yearly goal of cleaning 50 sumps per year.
Sumps are deep, perforated manholes, which collect run-off and debris.
In 1998, we removed 91 yards of debris from sumps. After this debris is dried, we haul it to a recycler. A sump collects all the debris which is carried by runoff. These sumps require our VacCon machine to remove this debris. This design allows debris to settle in the sump, the oil-water elbow keeps oils and floatable debris below the elbow, allowing only the cleaner runoff into the drywell.
