If an External Bypass structure is present in the association with the BioFilter
™
system(s), it should be inspected for the following items:
1. Inspect curbing and inlet opening to ensure that the structure is not blocked in order to convey high flow conditions
2. Use manual removal efforts or Vacuum system as needed.
3. If applicable, remove manhole cover to facilitate Inspection and Maintenance
During Construction
First Year Post-Construction
Inspect the Bio-Filter™ every three months and clean the system as needed.
Inspect and clean the system once annually regardless of whether it has reached its sediment or floatable pollutant storage capacity.
Second and Subsequent Years Post-Construction
External Bypass Structures
Bypass structures should be inspected whenever the Bio-Filter™ is inspected and maintained as needed.

Maintenance Company Information
Maintenance Schedule
Cleaning
Schedule cleaning with local vactor company or AquaShield™'s Maintenance Department to
remove sediments, oils, and other floatable pollutants with a vactor trailer. The spent biomedia
and sediment generally do not require any special treatment or handling for disposal. The filter
media can be recycled as fuel material, sent to a subtitle D landfill. AquaShield
™
always
recommends that all materials removed during the maintenance process be handled and
disposed of in accordance with local and state requirements.
Inspect the Bio-Filter™ every three months and clean the system as needed. The Bio-Filter™ should be inspected and cleaned at the end of
construction regardless of whether it has reached its sediment or oil storage capacity.
If the Bio-Filter™ reached full sediment or floatable pollutant capacity in less than 12 months in the First Year Post-Construction, the system
should be inspected once every six months and cleaned as needed. The Bio-Filter™ should be cleaned annually regardless of whether it
reaches its sediment or floatable pollutant capacity.
If the Bio-Filter™ did not reach full sediment or floatable pollutant capacity in the First Year Post-Construction, the system can be inspected
and cleaned on a frequency commensurate with site conditions.
