The primary purpose of the Jellyfish® Filter is to capture and remove
pollutants from stormwater runoff. As with any filtration system,
these pollutants must be removed to maintain the filter's maximum
treatment performance. Regular inspection and maintenance are
required to insure proper functioning of the system.
Maintenance frequencies and requirements are site specific and vary
depending on pollutant loading. Additional maintenance activities
may be required in the event of non-storm event runoff, such as
base-flow or seasonal flow, an upstream chemical spill or due to
excessive sediment loading from site erosion or extreme runoff
events. It is a good practice to inspect the system after major storm
events.
Inspection activities are typically conducted from surface
observations and include:
Observe if standing water is present
y
Observe if there is any physical damage to the deck or
y
cartridge lids
Observe the amount of debris in the Maintenance
y
Access Wall (MAW) or inlet bay for vault systems
Maintenance activities include:
Removal of oil, floatable trash and debris
y
Removal of collected sediments
y
Rinsing and re-installing the filter cartridges
y
Replace filter cartridge tentacles, as needed

4.0 Inspection Timing
Inspection of the Jellyfish Filter is key in determining the maintenance
requirements for, and to develop a history of, the site's pollutant
loading characteristics. In general, inspections should be performed
at the times indicated below; or per the approved project
stormwater quality documents (if applicable), whichever is more
frequent.

1.
A minimum of quarterly inspections during the first year of
operation to assess the sediment and floatable pollutant
accumulation, and to ensure proper functioning of the system.
2.
Inspection frequency in subsequent years is based on the
inspection and maintenance plan developed in the first year of
operation. Minimum frequency should be once per year.
3.
Inspection is recommended after each major storm event.
4.
Inspection is required immediately after an upstream oil, fuel or
other chemical spill.
5.0 Inspection Procedure
The following procedure is recommended when performing
inspections:
1.
Provide traffic control measures as necessary.
2.
Inspect the MAW or inlet bay for floatable pollutants such as
trash, debris, and oil sheen.
3.
Measure oil and sediment depth in several locations, by
lowering a sediment probe until contact is made with the floor
of the structure. Record sediment depth, and presences of any
oil layers.
4.
Inspect cartridge lids. Missing or damaged cartridge lids to be
replaced.
5.
Inspect the MAW (where appropriate), cartridge deck and
receptacles, and backwash pool weir, for damaged or broken
components.
5.1 Dry weather inspections
Inspect the cartridge deck for standing water, and/or
y
sediment on the deck.
No standing water under normal operating conditions.
y
Standing water inside the backwash pool, but not
y
outside the backwash pool indicates, that the filter
cartridges need to be rinsed.
