Operation and Maintenance
The Stormwater
Management StormFilter@
Vault, Cast-In-Place, and Linear Units
Important: These guidelines should be used
as a part of your site stormwater
management plan.
Description
The Stormwater Management StormFilter@
(StormFilter) is a passive, flow-through,
stormwater filtration system. The system is
comprised of one or more vaults that house
rechargeable, media-filled, filter cartridges.
The StormFilter works by passing
stormwater through the media-filled
cartridges, which trap particulates and
adsorb materials such as dissolved metals
and hydrocarbons. Once filtered through the
media, the treated stormwater is directed to
a collection pipe or discharged into an open
channel drainage way.
The StormFilter is offered in multiple
configurations, including vault, linear, catch
basin, manhole, and cast-in-place. The
vault, linear, manhole, and catch basin
models utilize pre-manufactured units to
ease the design and installation processes.
The cast-in-place units are customized for
larger flows and may be either covered or
uncovered underground units.
Purpose
The StormFilter is a passive, flow-through,
stormwater filtration system designed to
improve the quality of stormwater runoff
from the urban environment before it enters
receiving waterways. It is intended to
function as a Best Management Practice
(BMP) to meet federal, state, and local
requirements for treating runoff in
compliance with the Clean Water Act.
Through independent third party studies, it
has been demonstrated that the StormFilter
is highly effective for treatment of first flush
flows and for treatment of flow-paced flows
during the latter part of a storm. In general,
the Storm Filter's efficiency is highest when
pollutant concentrations are highest. The
primary non-point source pollutants targeted
for removal by the StormFilter are:
suspended solids (TSS), oil and grease,
soluble metals, nutrients, organics, and
trash and debris.
Sizing
The StormFilter is sized to treat the peak
flow of a water quality design storm. The
peak flow is determined from calculations
based on the contributing watershed
hydrology and from a design storm
magnitude set by the local stormwater
management agency. The particular size of
a Storm Filter unit is determined by the
number of filter cartridges (see Figure 1)
required to treat this peak flow.
The flow rate through each filter cartridge is
adjustable, allowing control over the amount
of contact time between the influent and the
filter media. The maximum flow rate
through each cartridge can be adjusted to
between 5 and 15 gpm using a calibrated
restrictor disc at the base of each filter
cartridge. Adjustments to the cartridge flow
rate will affect the number of cartridges
required to treat the peak flow.

Vault, CIP and Linear Storm Filter Operation and Maintenance Guidelines
Basic Function
The Storm Filter is designed to siphon
stormwater runoff through a filter cartridge
containing media. A variety of filter media is
available and can be customized for each
site to target and remove the desired levels
of sediments, dissolved phosphorus,
dissolved metals, organics, and oil and
grease. In many cases, a combination of
media is recommended to maximize the
effectiveness of the stormwater pollutant
removal.
Figure 1. The StormFilter Cartridge
Priming System Function
When stormwater in the Storm Filter unit
enters a Storm Filter cartridge, it percolates
horizontally through the cartridge's filter
media and collects in the center tube of the
cartridge, where the float in the cartridge is
in a closed (downward) position.
Water continues to pass through the filter
media and into the cartridge's center tube.
The air in the cartridge is displaced by the
water and purged from beneath the filter
hood through the one-way check valve
located in the cap. Once the center tube is
filled with water (approximately 18 inches
deep), there is enough buoyant force on the
float to open the float valve and allow the
treated water in the center tube to flow into
the under-drain manifold. This causes the
check valve to close, initiating a siphon that
draws polluted water throughout the full
surface area and volume of the filter. Thus,
the entire filter cartridge is used to filter
water throughout the duration of the storm,
regardless of the water surface elevation in
the unit. This siphon continues until the
water surface elevation drops to the
elevation of the hood's scrubbing
regulators.
The cartridges are connected to the under-
drain manifold with a plastic connector.
Since some media used is potentially
buoyant, a threaded connector affixed to the
under-drain manifold (with glue or other
adhesive) is necessary to ensure that the
cartridge isn't lifted out of place. For the
heavier compost media, a slip connector is
used.
The Storm Filter is also equipped with flow
spreaders that trap floating debris and
surface films, even during overflow
conditions. Depending on individual site
characteristics, some systems are equipped
with high and/or base flow bypasses. High
flow bypasses are installed when the
calculated peak storm event generates a
flow that overcomes the overflow capacity of
the system. This is especially important for
precast systems. Base flow bypasses are
sometimes installed to bypass continuous
inflows caused by ground water seepage,
which usually do not require treatment. All
Storm Filter units are designed with an
overflow. The overflow operates when the
inflow rate is greater than the treatment
capacity of the filter cartridges.

Maintenance Guidelines
The primary purpose of the Storm Filter is to
filter out and prevent pollutants from
entering our waterways. Like any effective
filtration system, periodically these
pollutants must be removed to restore the
Storm Filter to its full efficiency and
effectiveness.
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 also good
practice to inspect the system after severe
storm events.
Types of Maintenance
Presently, procedures have been developed
for two levels of maintenance:
· Inspection/minor maintenance
· Major maintenance.
Inspection/minor maintenance activities are
combined since minor maintenance does
not require special equipment and typically
little or no materials are in need of disposal.
Inspection/minor maintenance typically
involves:
· Inspection of the vault itself
· Removal of vegetation and
trash and debris.
Major maintenance typically includes:
· Cartridge replacement
· Sediment removal
Important: Applicable safety (OSHA) and
disposal regulations should be followed
during all maintenance activities.
Maintenance Activity Timing
@2006 CONTECH Stormwater Solutions
Two scheduled inspections/maintenance
activities should take place during the year.
First, an inspection/minor maintenance
activity should be done. During the minor
maintenance activity (routine inspection,
debris removal), the need for major
maintenance should be determined and, if
disposal during major maintenance will be
required, samples of the sediments and
media should be obtained.
Second, if required, a major maintenance
activity (replacement of the filter cartridges
and associated sediment removal) should
be performed.
In addition to these two scheduled activities,
it is important to check the condition of the
StormFilter unit after major storms for
damage caused by high flows and for high
sediment accumulation that may be caused
by localized erosion in the drainage area. It
may be necessary to adjust the
maintenance activity schedule depending
on the actual operating conditions
encountered by the system.
In general, minor maintenance activities will
occur late in the rainy season, and major
maintenance will occur in late summer to
early fall when flows into the system are not
likely to be present.
Maintenance Activity Frequency
The primary factor controlling timing of
maintenance for the Storm Filter is
sedimentation.

Vault, CIP and Linear Storm Filter Operation and Maintenance Guidelines
A properly functioning system will remove
solids from water by trapping particulates in
the porous structure of the filter media. The
flow through the system will naturally
decrease as more and more solids are
trapped. Eventually the flow through the
system will be low enough to require
replacement of the cartridges. It may be
possible to extend the usable span of the
cartridges by removing sediment from
upstream trapping devices on an as-needed
basis in order to prevent material from being
re-suspended and discharged to the
system.
Site conditions greatly influence
maintenance requirements. StormFilter
units located in areas with erosion or active
construction should be inspected and
maintained more often than those in fully
stabilized areas.
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 large storms.
Ultimately, inspection and maintenance
activities should be scheduled based on the
historic records and characteristics of an
individual StormFilter system. It is
recommended that the maintenance agency
develop a database to properly manage
Storm Filter maintenance programs.
Prior to

· One time per year
· After Major Storms

database, the following
frequencies should be

· One time per year
· In the event of a chemical spill
Frequencies should be updated as required.
The recommended initial frequency for
inspection/minor maintenance is two times
per year for precast units. StormFilter units
should be inspected after all major storms.
Sediment removal and cartridge
replacement on an annual basis is
recommended until further knowledge is
gained about a particular system.
Once an understanding of site
characteristics has been established,
maintenance may not be needed for one to
two years, but inspection is warranted.
Maintenance Methods
Inspection/Minor Maintenance
The primary goal of a maintenance
inspection is to assess the condition of the
cartridges relative to the level of sediment
loading. It may be desirable to conduct this
inspection during a storm to observe the
relative flow through the filter cartridges. If
the submerged cartridges are severely
plugged, large amounts of sediments will be
present and very little flow will be
discharged from the drainage pipes. If this
is the case, it is likely that the cartridges
need to be replaced.
Warning: In the case of a spill, the worker
should abort maintenance activities until the
proper guidance is obtained. Notify the
local hazard control agency and CONTECH
Stormwater Solutions immediately.
To conduct an inspection and/or minor
maintenance:
Important: Maintenance must be performed
by a utility worker familiar with StormFilter
units.
1. If applicable, set up safety equipment to
protect pedestrians from fall hazards
due to open vault doors or when work is
being done near walkways or roadways.
2. Visually inspect the external condition of
the unit and take notes concerning
defects/problems.

3. Open the doors to the vault and allow
the system to air out for 5-10 minutes.
4. Without entering the vault, inspect the
inside of the unit, including components.
5. Take notes about the external and
internal condition of the vault.
Be sure to record the level of sediment
build-up on the floor of the vault, in the
forebay, and on top of the cartridges. If
flow is occurring, note the level of water
and estimate the flow rate per drainage
pipe. Record all observations.
6. Remove large loose debris and trash
using a pole with a grapple or net on the
end.
7. Close and fasten the door.
8. Remove safety equipment.
9. Make notes about the local drainage
area relative to ongoing construction,
erosion problems, or high loading of
other materials to the system.
10. Finally, review the condition reports from
the previous minor and major
maintenance visits, and schedule
cartridge replacement if needed.
Major Maintenance
Depending on the configuration of the
particular system, a worker may be required
to enter the vault to perform some tasks.
Important: If vault entry is required, OSHA
rules for confined space entry must be
followed.
Filter cartridge replacement should occur
during dry weather. It may be necessary to
plug the filter inlet pipe if base flows exist.
Standing water present in the vault should
be regarded as polluted and should be
contained during this operation by
temporarily capping the manifold
connectors.
Replacement cartridges will be delivered to
the site. Information concerning how to
obtain the replacement cartridges is
available from CONTECH Stormwater
Solutions.
Warning: In the case of a spill, the worker
should abort maintenance activities until
the proper guidance is obtained. Notify the
local hazard control agency and
CONTECH Stormwater Solutions
immediately.
To conduct cartridge replacement and

contechstormwater.com
Vault, CIP and Linear StonnFilter Operation and Maintenance Guidelines
, .
Important: This activity will require that
workers enter the vault to remove the
cartridges from the drainage system.
Method 1:
a. Using an appropriate sling, attach
the cable from the boom, crane, or
tripod to the cartridge being
removed. Contact CONTECH
Stormwater Solutions for
specifications on appropriate
attachment devices.
This activity will require that workers
enter the vault to remove the
cartridges from the drainage system
and place them under the vault
opening for lifting.
Important: Note that cartridges
containing media other than the leaf
media require unscrewing from their
threaded connectors. Take care not
to damage the manifold connectors.
This connector should remain
installed in the manifold and capped
if necessary.
b. Remove the used cartridges
(250 Ibs. each) from the vault.
Important: Care must be used to
avoid damaging the cartridges
during removal and installation. The
cost of repairing components
damaged during maintenance will be
the responsibility of the owner
unless CONTECH Stormwater
Solutions performs the maintenance
activities and damage is not related
to discharges to the system.
c. Set the used cartridge aside or
load onto the hauling truck.
d. Continue steps a through c until
all cartridges have been removed.
Method 2:
a. Unscrew the cartridge cap.
b. Remove the cartridge hood.
c. Tip the cartridge on its side.
Important: Note that cartridges
containing media other than the leaf
media require unscrewing from their
threaded connectors. Take care not
to damage the manifold connectors.
This connector should remain
installed in the manifold and capped
if necessary.
d. Empty the cartridge onto the vault
floor.
e. Set the empty, used cartridge
aside or load onto the hauling truck.
f. Continue steps a through e until
all cartridges have been removed.
9. Remove deposited sediment from the
floor of the vault and, if large amounts
are present, from the forebay. This can
usually be accomplished by shoveling
the sediment into containers, which,
once full, are lifted mechanically from
the vault and placed onto the hauling
truck. If Method 2 in Step 8 is used to
empty the cartridges, or in cases of
extreme sediment loading, a vactor
truck may be required.
10. Once the sediments are removed,
assess the condition of the vault and the
condition of the manifold and
connectors. The connectors are short
sections of 2-inch schedule 40 PVC, or
threaded schedule 80 PVC that should
protrude above the floor of the vault.
a. If required, apply a light coating of
FDA approved silicon grease to the
outside of the exposed portion of
the connectors. This ensures a
watertight connection between the
cartridge and the drainage pipe.
b. Replace any damaged connectors.
11. Using the boom, crane, or tripod, lower
and install the new cartridges. Once

Related Maintenance Activities
(Performed on an as-needed basis)
StormFilter units are often just one of many
components in a more comprehensive
stormwater drainage and treatment system.
The entire system may include catch
basins, detention vaults, sedimentation
vaults and manholes, detention/retention
ponds, swales, artificial wetlands, and other
miscellaneous components.
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
Storm Filter maintenance activities.
In addition to considering upstream
facilities, it is also important to correct any
problems identified in the drainage area.
Drainage area concerns may include:
erosion problems, heavy oil and grease
loading, and discharges of inappropriate
materials.
@2006 CONTECH Stormwater Solutions
Material Disposal
The accumulated sediment found in
stormwater treatment and conveyance
systems must be handled and disposed of
in a manner that will not allow the material
to affect surface or ground water. 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. It is not appropriate to
discharge untreated materials back to the
stormwater drainage system.
Part of arranging for maintenance to occur
should include coordination of disposal of
solids (landfill coordination) and liquids
(municipal vacuum truck decant facility,
local wastewater treatment plant, on-site
treatment and discharge).
Owners should contact the local public
works department and inquire about how
the department disposes of their street
waste residuals. CONTECH Stormwater
Solutions will determine disposal methods
or reuse of the media contained in the
cartridges. If the material has been
contaminated with any unusual substance,
the cost of special handling and disposal
will be the responsibility of the owner.
