Tree Box Filter Maintenance and Inspection Guidelines
In
general, maintenance includes annual routine inspection and maintenance
activities. Also,
the first two years of maintenance are typically included with the purchase
of single and multiple-unit tree box filters.
These would include removal of trash, debris and sediment, replenishment of
the mulch, and care or replacement of plants. During extreme droughts the
plants may need to be watered in the same manner as any other landscape
material. In the event of a chemical spill all of the soil and plants
should be removed disposed of properly and replace with new uncontaminated
filter media and plants. Tree box
filters require low maintenance and a small drainage area with respect to
surface area.
