Page 16 of 32
In addition to these two activities, it is important to check
the condition of the StormFilter unit after major storms for

accumulation that may be caused by localized erosion in the
drainage area. It may be necessary to adjust the inspection/
maintenance schedule depending on the actual operating
conditions encountered by the system. In general, inspection
activities can be conducted at any time, and maintenance should
occur, if warranted, during dryer months in late summer to early
fall.
Maintenance Frequency
The primary factor for determining frequency of maintenance for
the StormFilter is sediment loading.
A properly functioning system will remove solids from water by

replacement. It may be possible to extend the usable span of the
cartridges by removing sediment from upstream trapping devices
on a routine as-needed basis, in order to prevent material from
being re-suspended and discharged to the StormFilter treatment
system.
The average maintenance lifecycle is approximately 1-5 years.
6LWHFRQGLWLRQVJUHDWO\LQÁXHQFHPDLQWHQDQFHUHTXLUHPHQWV
StormFilter units located in areas with erosion or active
construction may need to be inspected and maintained more
often than those with fully stabilized surface conditions.
Regulatory requirements or a chemical spill can shift maintenance
timing as well. The maintenance frequency may be adjusted as
additional monitoring information becomes available during the
inspection program. Areas that develop known problems should
be inspected more frequently than areas that demonstrate no
problems, particularly after major storms. Ultimately, inspection
and maintenance activities should be scheduled based on the
historic records and characteristics of an individual StormFilter
system or site. It is recommended that the site owner develop
a database to properly manage StormFilter inspection and
maintenance programs..
Maintenance Guidelines
The primary purpose of the Stormwater Management

pollutants must be removed to restore the StormFilter to its full
HIÀFLHQF\DQGHIIHFWLYHQHVV
Maintenance requirements and frequency are dependent on the
pollutant load characteristics of each site. Maintenance activities
may be required in the event of a chemical spill or due to
excessive sediment loading from site erosion or extreme storms. It
is a good practice to inspect the system after major storm events.
Maintenance Procedures
Although there are many effective maintenance options, we
EHOLHYHWKHIROORZLQJSURFHGXUHWREHHIÀFLHQWXVLQJFRPPRQ
equipment and existing maintenance protocols. The following
two-step procedure is recommended::
1.Inspection
• Inspection of the vault interior to determine the need for
maintenance.
2.Maintenance
• Cartridge replacement
• Sediment removal
Inspection and Maintenance Timing
At least one scheduled inspection should take place per year with
maintenance following as warranted.
First, an inspection should be done before the winter season.
During the inspection the need for maintenance should be
determined and, if disposal during maintenance will be required,
samples of the accumulated sediments and media should be
obtained.
6HFRQGLIZDUUDQWHGDPDLQWHQDQFH UHSODFHPHQWRIWKHÀOWHU
cartridges and removal of accumulated sediments) should be
performed during periods of dry weather.
Page 17 of 32
Inspection Procedures
The primary goal of an inspection is to assess the condition of
the cartridges relative to the level of visual sediment loading as
it relates to decreased treatment capacity. It may be desirable to
conduct this inspection during a storm to observe the relative

drainage pipes. If this is the case, then maintenance is warranted
and the cartridges need to be replaced.
Warning: In the case of a spill, the worker should abort
inspection activities until the proper guidance is obtained.
Notify the local hazard control agency and Contech Engineered
Solutions immediately.
To conduct an inspection:

Related Maintenance Activities -
Performed on an as-needed basis
StormFilter units are often just one of many structures in a more
comprehensive stormwater drainage and treatment system.
In order for maintenance of the StormFilter to be successful, it
is imperative that all other components be properly maintained.
The maintenance/repair of upstream facilities should be carried
out prior to StormFilter maintenance activities.
In addition to considering upstream facilities, it is also important
WRFRUUHFWDQ\SUREOHPVLGHQWLÀHGLQWKHGUDLQDJHDUHD'UDLQDJH
area concerns may include: erosion problems, heavy oil loading,
and discharges of inappropriate materials.
Material Disposal
The accumulated sediment found in stormwater treatment
and conveyance systems must be handled and disposed of in
accordance with regulatory protocols. It is possible for sediments
to contain measurable concentrations of heavy metals and
organic chemicals (such as pesticides and petroleum products).
Areas with the greatest potential for high pollutant loading
include industrial areas and heavily traveled roads.
Sediments and water must be disposed of in accordance with
all applicable waste disposal regulations. When scheduling
maintenance, consideration must be made for the disposal of
solid and liquid wastes. This typically requires coordination with
DORFDOODQGÀOOIRUVROLGZDVWHGLVSRVDO)RUOLTXLGZDVWHGLVSRVDO
a number of options are available including a municipal vacuum
truck decant facility, local waste water treatment plant or on-site
treatment and discharge.
