Maintenance Overview—
A. Every installed MWS — Linear unit is to be maintained by the Supplier, or a
Supplier approved contractor. The cost of this service varies among providers
B The MWS — Linear is a multi-stage self-contained treatment train for stormwater
treatment. Each stage protects subsequent stages from clogging. Stages include-
screening, separation, cartridge media filtration, and biofiltration The biofiltration stage
contains various types of vegetation which will require annual evaluation and trimming
1. Clean Bio Clean® Catch Basin Filter— Screening is provided by well proven
catch basin filter. The filter has a trash and sediment capacity of 2 (curb type)
and 4 (grate type) cubic feet. The filter removes gross solids, including litter, and
sediments greater than 200 microns. This procedure is easily done by hand or
with a small industrial vacuum device. This filter is located directly under the
manhole or grate access cover.
2. Clean Separation (sediment) Chamber— separation occurs in the pre-
treatment chamber located directly under the curb or grated inlet. This chamber
has a capacity of approximately 21 cubic feet for trash, debris and sediments.
This chamber targets TSS, and particulate metals and nutrients This procedure
can be performed with a standard vacuum truck. This chamber is located directly
under the manhole or grate access cover
3. Replace Cartridge Filter Media (BioMediaGREENTM)— Primary filtration is
provided by a horizontal flow cartridge filter utilizing BioMediaGREEN blocks
Each cartridge has a media surface area of 35 square feet. The large surface
area will insure long term operation without clogging. The cartridge filter with
BioMediaGREEN targets fine TSS, metals, nutrients, hydrocarbons, turbidity and
bacteria. Media life depends on local loading conditions and can easily be
replaced and disposed of without any equipment. The filters are located in the
pre-treatment chamber. Entry into chamber required to replace BioMediaGREEN
blocks Each cartridge contain 14 pieces of 20" tall BioMediaGREEN
4. Replace Drain Down Filter Media (BioMediaGREENTM)—A drain down filter,
similar in function to the perimeter filter is located in the discharge chamber. This
filter allows standing water to be drained and filtered out of the separation
chamber This addresses any vector issues, by eliminating all standing water
within this system. Replacement of media takes approximately 5 minutes and is
performed without any equipment.
5. Trim Vegetations — The system utilizes multiple plants in the biofiltration
chamber to provide enhanced treatment for dissolved pollutants including
nutrients and metals The vegetation will need to be maintained (trimmed) as
needed This can be done as part of the project normal landscape maintenance.
NO FERTILIZER SHALL BE USED IN THIS CHAMBER.
6. Evaluate Wetland Media Flow Hydraulic Conductivity —The systems flow
can be assessed from the discharge chamber. This should be done during a rain
event. By viewing into the discharge chamber the flow out of the system can be
observed. If little to know flow is observed from the lower valve or orifice plate this
is a sign of potential wetland media (biofiltration) maintenance needs
7. Wetland Media Replacement— biofiltration is provided by an advance
horizontal flow vegetated wetland. This natural filter contains a mix of sorptive
media that supports abundant plant life. This biofilter targets the finest TSS,
dissolved nutrients, dissolved metals, organics, pesticides, oxygen demanding
substances and bacteria This filter provides the final polishing step of treatment.
If prior treatment stages are properly maintained, the life of this media can be up
to 20 years. Replacement of the media is simple. Removal of spent media can be
done with a shovel of a vacuum truck.
C. The MWS— Linear catch basin filter, separation chamber, cartridge filter media and
wetland media are designed to allow for the use of vacuum removal of captured
pollutants and spent filter media by centrifugal compressor vacuum units without causing
damage to the filter or during normal cleaning and maintenance. Filter and chambers
can be cleaned from finish surface through standard manhole or grate access.
Maintenance Procedures —
1. Clean Bio Clean®Catch Basin Filter— Modular Wetland Systems, Inc. recommends
the catch basin filter be inspected and cleaned a minimum of once every six months
and replacement of hydrocarbon booms once a year. The procedure is easily done with
the use of any standard vacuum truck. Th!s procendure is/%--_S IV I
1. Remove grate or manhole to gain access to catch basin filter insert. Remove
the deflector shield (grate type only) with the hydrocarbon boom attached.
Where possible the maintenance should be performed from the ground
surface Note: entry into an underground stormwater vault such as an inlet
vault requires certification in confined space training.
2 Remove all trash, debris, organics, and sediments collected by the inlet filter
insert. Removal of the trash and debris can be done manually or with the use
of a vacuum truck. The hose of the vacuum truck will not damage the screen
of the filter.
3. Evaluation of the hydrocarbon boom shall be performed at each cleaning. If
the boom is filled with hydrocarbons and oils it should be replaced Attach
new boom to basket with plastic ties through pre-drilled holes in basket. Place
the deflector shield (grate type only) back into the filter.
4. Transport all debris, trash, organics and sediments to approved facility for
disposal in accordance with local and state requirements.
5 The hydrocarbon boom may be classified as hazardous material and will have
to be picked up and disposed of as hazardous waste. Hazardous material can
only be handled by a certified hazardous waste trained person (minimum 24-
hour hazwoper)
2. Clean Separation (sediment) Chamber— Modular Wetland Systems, Inc.
recommends the separation chamber be inspected and cleaned a minimum of once a
year The procedure is easily done with the use of any standard vacuum truck ;
