SUBJECT. A RESOLUTION OF THE MAYOR AND CITY COMMISSION OF THE CITY
OF MIAMI BEACH, FLORIDA, APPROVING, PURSUANT TO SECTION 2-
367(D) OF THE MIAMI 'BEACH CODE FOR SOLE SOURCE PURCHASES,
THE PURCHASE OF FOUR (4) PORTABLE 2.55 M HDPE DOWNSTREAM
DEFENDER SYSTEMS AND RELATED ITEMS OR SOFTWARE BY HYDRO
INTERNATIONAL FOR PURPOSES OF STORMWATER TREATMENT
DURING KING TIDE EVENTS, IN KEY LOCATIONS IN THE CITY, IN AN
AMOUNT NOT TO EXCEED $230,560.
RECOMMENDATION
The Administration recommends approving the Resolution.
During the rainy and king tide seasons, the Public Works Department deploys temporary diesel
pumps to reduce flooding in areas throughout the. City. The City.has Miami -Dade County
Department of Environmental Resource Management (DERM) Class V Temporary Dewatering
Permits for this type of operation. In recent discussions with the regulatory agency, the
implementation of additional water quality treatment systems has been requested when the
temporary pumps are set up to discharge directly into Biscayne Bay. Public Works determined
that the purchase of four portable 2.55 M HDPE Downstream Defenders by Hydro Intemational
is required to meet the additional water treatment, requirements.
The stormwater must be treated prior to discharge, using a stormwater treatment system
capable of reducing the total suspended solids and turbidity. Due to the significant site
constraints associated with the typical locations where the temporary pumps are deployed, the
portable water quality treatment system must meet stringent requirements, including a
significantly reduced footprint, while maintaining a high rate of contaminant removal.
The portable Downstream Defender System is a well -tested product by an established
manufacturer. This product is patented and provides the required enhanced treatment
performance, flow capacity, materials of construction, no power or water required, vac truck
accessibility, flexibility and mobility, footprint, and schedule. The Portable 2.55 M HDPE
Downstream Defender System by Hydro International meets all of these constraints without
exception and has a total estimated cost of $230,560 for four (4) devices, which includes 10%
Page 308 of 991
contingency.
Pursuant to Section 2-367(d)(2), the Procurement Department publicly released Intent to Sole
Source (ITS) No. 2023-399-NA on March 29, 2023. The Intent to Sole Source (ITS)
document provides details to , potential bidders on the Cites needs, and requests that any
vendor that believes it can provide the City with ,the necessary items should submit written
notification to the City for consideration. No response to the ITS was received.
Therefore, based on the notification from the manufacturers and the results of the ITS, this item
serves as a formal request for approval for the sole source purchase of four (4) portable 2.55 M
HDPEDownstream Defender Systems by HydroIntemational, for the purpose of stormwater
treatment during king tide events in key locations throughout the City of Miami Beach.

Please provide the following information in order to document the sole source request and prepare the
appropriate recommendation to the City Manager and Mayor and City Commission:
1. Explain why the product/service requested is the only product/service that can satisfy your
requirements and explain why alternatives are unacceptable. Be specific with regard to specifications,
features, characteristics, requirements, capabilities and compatibility. Describe what steps have been
undertaken to make this determination.
During king tide and wet season, a total of 4 locations within the City flood with as much as two feet of
water due to high ground water and rain entering the stormwater system. Some of these locations are
in residential neighborhoods, and some are along major streets within the City. At each location, traffic
flow is impeded and pedestrian flow is unsafe and almost impossible.
In order to relieve flooding in these areas, the Miami Beach Public Works Department on a seasonal
basis uses a series of temporary diesel pumps to pump groundwater from a manhole at each location
over the sea wall and into the Bay or at some locations, into another stormwater manhole which drains
into the bay. To date, this has successfully relieved the flooding and reduced complaints of residents
and visitors.
However, Miami Dade County has required that the Miami Beach obtain a DERM Class V Temp
dewatering permit to discharge stormwater into the Bay. As a condition of this permit, the stormwater
must be treated prior to discharge using a stormwater treatment system capable of reducing the total
suspended solids and turbidity.
Due to the proposed location of the treatment systems and other factors, there are a number of
significant constraints which must -be met by the temporary treatment system. In addition to being a
well -tested product manufactured by an established manufacturer, constraints include the following:
• Patent -The DownStream Defender Select is a patented device as it relates to an inlet module
for a separator, a separator and a method of manufacturing a separator. It is patent approved in
Great Britian with a patent number of GB 2593669 and is patent pending in the US.
The patent involves the separator itself, a method of manufacturing the separator and a specific inlet
design; all of which help provide the following benefits:
➢ Significantly improved separation efficiency in separating TSS from water. This provides a cleaner
effluent and more solids capture within the unit itself.
➢ A reduction in the washout of captured pollutants which have already been trapped in the
separator. This means more solids that have already been captured stay captured even during
periods of high flows instead of w8ftac, Nj0EM contaminating the effluent.
➢ Increased ability to handle peak flows while saving space. This means that higher flows can be
accomplished in a smaller space while still providing a very high level of treatment.
Please reference the offached letter for additional information.
Treatment Performance - The stormwater treatment system should be sized to meet the permit
discharge requirements of a turbidity of no more than 29 NTU greater than the background turbidity in
the bay and 40 mg/I TSS at, the pumping flow rate required. The Temporary 2.55 M HDPE Downstream
Defender has the treatment capabilities mandate by permit for the small footprint needed for space
constraints.
Flow Capacity - Public Works has determined through experience that a pumping rate of
approximately 1,500 GPM is required to prevent flooding in the areas of concern. It is therefore critical
that any stormwater treatment system have a full treatment capacity with overflow of at least this flow
rate or some of the stormwater will be discharged without treatment. The Temporary 2.55 M HDPE
Downstream Defender can meet the treatment mandated by permit at 1,500 GPM flow rates.
Materials of Construction- Since the stormwater treatment system will be used above ground
and moved every year, the materials of construction of the treatment system need to be very strong,
resistant to heat and sunlight and at the same time light weight to be able to deploy onsite every 6
months. Public Works has determined that the best materials of construction for this site is HDPE
because it meets all these criteria. The Downstream Defender is manufactures in HDPE material for
these temporary applications.
• No Power Required- All sites do not have easy access to power. Bringing in temporary power or
utilizing a separate generator would cause additional safety and logistic concerns and for this reason
Public Works has determined that one of the constraints of the treatment system is that it cannot require
power. The Temporary 2.55 M HDPE Downstream Defender requires no power or moving parts for
stormwater treatment.
• No Water Reauired- Most of the sites do not have easy access to either potable or reuse water.
Since temporary water lines would be difficult to implement and subject to vandalism and even to
potential potable water system contamination, Public Works has determined that one of the constraints
of the treatment system is that it cannot require an outside water source. The Temporary 2.55 M HDPE
Downstream Defender requires no water for stormwater treatment.
Vac Truck Accessible- Public Works owns several vac trucks which are currently used for other
purposes including pumping out manholes, pumping and maintenance of existing below ground
DownStream Defenders. Additionally, Public Works hires a third party contractors to be able to clean all
stormwater system per NPDES permit. Because Public Works is already set up with vac trucks, the
stormwater treatment system will need to be accessible to be cleaned of solids using a vac truck. The
Temporary 2.55 M HDPE Downstream Defender is easily cleaned using vac truck same as the
permanent concrete Downstream Defender.
Flexible and Mobile - The treatment units will need to be put in place every year prior to the wet
season and removed once the wet season is over. The units will then be moved to the Public Works yard
and stored until the next season. Additionally, the treatment systems will need to be re -located around
the City from time to time as the need for pumping the stormwater changes within the City. They may
also occasionally be used as treatment for temporary dewatering on various projects throughout the
City. All of these uses require a stormwater treatment that can be loaded onto a truck with a fork truck
and moved around the streets of the City by Public Works service personnel without the use of a crane
or other specialized equipment. The Temporary 2.55 M HDPE Downstream Defender is light weight and
easy to transport unlike other solutions available in the market.
Footprint- Several of the treatment systems will need to be located in major streets essentially
taking up no more than a parking space and, in some cases, partially blocking a lane of traffic. For this
reason, a small footprint is absolutely critical. A treatment system that is too large or requires excess
Page 311 of 991
maintenance would be a potential safety concern to motorists and to Public Works Staff. The
Temporary 2.55 M HDPE Downstream Defender requires no more than half a parking spot.
• Schedule - The stormwater treatment system must be in place and operational by the
upcoming wet season on June 1 st to allow the City to meet the permit discharge requirements while
pumping out the flooded areas. Pre -purchase of the temporary HDPE Downstream Defenders will
shorten the schedule by several months and allow the City to meet the discharge requirements during
the upcoming wet season.
The temporary DownStream Defender is the perfect device for this application because it is made from
structurally re -enforced HDPE, resistant to heat and sunlight and is light enough to be easily moved in a
temporary application for use during the wet season. The temporary HDPE Downstream Defenders will
be moved into position and will occupy approximately'/2 of a parking spot for the wet season, then
removed and put into storage during the off season. They are flexible enough to be moved to any
application in the City where treatment is required by City staff with existing city equipment and could
even be mounted on a small trailer and moved around the City on a regular basis if desired.
Additionally, Miami Beach already has multiple successfully installed DownStream Defenders which
have been on place for years, and Public Works, is familiar with the performance and cleaning
associated with them.
2. Explain why this service provider, supplier, or manufacturer is the only practicably available source from
which to obtain this product or service and describe the efforts that were made to verify and confirm
whether, or not, this is so. (Obtain and include a letter from the manufacturer confirming, claims made
by distributors of exclusive distributorships for the product or service, if, that is cited as a reason for this
Sole Source.)
As indicated above, this, application is very unique because there of the significant number of
constraints that must be met. The Down Stream Defender meets all of these constraints without
exception.
The Downstream Defender is unique in that it is a patented stormwater vortex separation device and is
the only advanced vortex separator on the market without an internal bypass mechanism, meaning
that 100% of the stormwater inflow entering the system is treated, ensuring maximum removal of
pollutants. It is the only above ground structurally re -enforced HDPE vortex separation stormwater
treatment system available that can meet the treatment within the required footprint.
The DownStream Defender is also the only HDPE above ground vortex separator without a by-pass and
with a large enough capacity and adequate performance to handle this project. The DownStream
Defender is unique in that it provides a very high level of stormwater treatment in a very small above
ground footprint of about'/2 of a car parking spot which is extremely important since some will be used
on the main streets of Miami Beach during tourist season. The 2.55M HDPE Downstream Defender will
remove particles down to 50 micron and will remove 95% of all particles 175 micron which should be
more than adequate to meet the permit requirements.
The DownStream Defender is certified and accepted in multiple states by multiple organizations for TSS
removal including Florida Department of Environmental Protection (FDEP). In fact, 28 DownStream
Defenders were recently purchased for the high -profile signature Miami Bridge Project.
3. Will this purchase obligate us to a particular vendor for future purchases? (Either in terms of
maintenance that only this vendor will be able to perform and/or N we purchase this item, will we need
more 'like" items in the future to match this one?)
No, this is a simple capital sale, and there will be no obligation to any vendor due to this purchase.
Although this vendor is the only vendor found which can meet all the specific constraints for this
particular application, this is a standalone purchase without obligations or ties to other purchases.
Specially regarding maintenance, there are no moving parts with this product, there are no sacrificial
wear parts with this product, and there is pgootKgo6yigotenance of specialized labor associated with
that is required to be supplied by the manufacturer.
Operation of the units essentially consists of opening a hatch and utilizing a vac truck to vac out the
accumulated solids from the unit. Miami Beach Public Works Department owns several vac trucks and
also works with several third -party stormwater maintenance companies with vac trucks which are
unaffiliated with this particular manufacture to clean out various existing sanitary sewer and stormwater
manholes. Thus, Miami Beach has multiple post capital sale operational options, none of which involve
this particular manufacturer and with no ongoing financial relationship with this company is anticipated
post capital sale.

4. Explain why the price for this product or service is considered to be fair and reasonable.
Miami Beach has standardized on two vendors for stormwater treatment solutions and has purchased
multiple units through competitive bids in the past and has a good understanding of the relative cost of
these products. In this case, none of the vendors provides a HDPE treatment system suitable for above
ground use which meets the previously identified restraints thus the request for a sole source.
As a further verification of a fair and reasonable pricing, at the request of the Public Works Department
the vendor has supplied several past Purchase Orders for the same or similar product for comparison
purposes. Based on an evaluation of these Purchase Orders, Public Works has cdncluded that the
pricing is fair and reasonable.
Price Verification Throuah Previous Purchase Orders
In order to verify pricing is fair and reasonable, see attached Purchase Orders for both the "permanent
below ground" concrete DownStream Defenders as well as the "temporary above ground" HDPE
DownStream Defenders. An explanation of pricing for each of these two is as follows:
a. S' Concrete DownStream Defender (Permanent/ Concrete)
Attached are the Purchase Orders for three 8' diameter concrete defenders. The scope is
essentially same as would be purchased by Miami Beach for this project so the only adjust made
to the price was for inflation as follows:

This indicates that the proposed price to Miami Beach of $34,800 is in line with previous purchase
order pricing from other customers for similar scope for permanent solution.
A below ground 8' Concrete permanent DownStream Defender will have additional cost for
design, permitting and installation which would surpass the cost of a temporary solution seen
below and may take up to an additional year to implement.
b. 2.55 M HDPE DownStream Defender
As previously indicated, the Metric 2.55M HDPE is a standard product offered by Hydro
International in the UK for years for use in buried systems. Attached is a Purchase Orders for
several 2.55 M diameter HDPE DownStream Defenders for comparison purposes. Since the price
of the PO is in Pound Sterling, the price of the Purchase Order has been adjusted to reflect the
exchange rate at the time of purchase as well as for inflation. Additionally, the Purchase Order
price has been added to reflect the cost of additional structural bands around the tanks to
allow for above ground use and freight to Miami Beach, all of which has been included in the
previous proposal to Miami Beach for the 2,55M HDPE DownStream Defenders. The adjusted
price for these previous PO's is as follows:

This indicates that the proposed price to Miami Beach of $52,400 is in line with previous purchase
order pricing from other customers for similar scope.
The temporary 2.55M HDPE DownStream Defenders does not require additional cost for design,
permitting and construction /installation. Additionally, the temporary 2.55M HDPE DownStream
Defenders can be onsite ready to use within 8-12 weeks of approved submittals.
5. Describe the negotiation efforts, N any, that have been made with the supplier to obtain the best
possible price.
Public works initially requested that the unit price of each unit be reduced which was agreed to.
Additionally, this vendor, at the request of Public Works, has provided a total of nine different proposals
with various scopes, unit sizes, materials of construction and stormwater treatment solutions in an
attempt to not only find the best solution, but to get as much scope added to the price as possible. As
an example, Public Works requested that the vendor provide a specific type of non-standard pipe
connection which the vendor agreed to provide at no charge. Additionally, Public Works requested the
vendor also provide additional service time to help with setup once the units are on -site at no extra cost
which was also agreed to by the vendor.
6. Explain the consequence(s) to the City or Public, including a dollar estimate of the financial impact N
this Sole Source is not approved.
Ultimately, the County will not allow the deployment of the temporary pump stations without having
cleaning devise prior to discharge to the bay. Without the deployment of the temporary pump station
the City streets will flood causing disruption to vehicle and pedestrian passage through main streets or
into residences and /or commercial properties.
The impact to the public of not having the temporary devises and pumps would mean this 4 locations
would remain under as much as two feet of water during wet season and they would be unable to get
to their parked cars, houses and in some cases shops and stores without walking through water. This
could obviously lead to other safety concerns and potential lawsuits involving significant amount of
money. Additionally, flooding could enter private property causing damage beyond the ROW.

Dear Patricia:
The DownStream Defender Select is a patented device as it relates to an inlet module for a separator, a
separator and a method of manufacturing a separator. It is patent approved in Great Britian with a patent
number of GB 2593669 and is patent.pending in the US. The first page of the GB patent has been attached for
reference.
The patent involves the separator itself, a method of manufacturing the separator and a specific inlet design; all
of which help provide the following benefits:
Significantly improved separation effeciency in separating TSS from water. This provides a cleaner
effluent and more solids cature within the unit itself.
• A reduction in the washout of captured pollutants which have alreaady been trapped in the
separator. This means more solids that have already been captured stay captured even during periods of
high flows instead of washing out and contaminating the effluent.
• Increased ability to handle peak flows while saving space. This means that higher flows can be
accomplished in a smaller space while still providing a very high level of treatment.
Please do nto hesitate to contact me with any questions or colmments regarding this poatent or if your require
additional information regarding the patent.
Bet Regards
G M. Lohse
Industrial Sales Manager

(54) Title of the Invention: An inlet module for a separator, a separator and a method of manufacturing a separator
Abstract Title: An inlet module for a separator, a separator and a method of manufacturing a separator
(57) An inlet module for a separator 2, the separator comprising a chamber 4 defined by a chamber wall having a
chamber wall opening. The inlet module 6 comprises an attachment portion 27 and a projecting portion 29
extending from the attachment portion.
The attachment portion is coupled to the chamber wall and comprises an inlet (36 fig 6) for receiving liquid passing
through the chamber wall opening. The projecting portion comprises an outlet (46 fig 6) directed such that the liquid
exits the inlet module and creates a circulating flow within the chamber about a central axis (15 fig 12) of the
chamber. The projecting portion is offset from the attachment portion such that a gap (76 fig 5) is formed between
the projecting portion and the chamber wall through which the circulating flow can pass. There is also described a
method of manufacturing a separator comprising obtaining an inlet module from a range of inlet modules; obtaining
a further inlet module from a range of inlet modules; removing a distal end of the projecting portion of the further
inlet module so as to form an outlet module; and coupling the inlet module and the outlet module to the chamber
wall so as to form a separator.

Section 2-367 (d), ofthe Mami Beach City Code, thatthe Cityintends lo make a noncompetitive award forthe goods or services, as stated below, available
onlyfrom a single source.
Goods or services required:
Currently( the Public Works Department is seeking to obtain four 2.55 M HDPE Downstream Defender System. Each Downstream Defender System shall
include intemals installed in a 2.55 M Diameter HOPE manhole reinforced for aboveground use. The 2.55 M HPDE DO is estimated to remove 95% of
particles down to 175 microns at 1500 GPM.
The HOPE Downstream DefenderSystems will be installed atfourlocations within the CityofMami Beach ('City') flooding with as much as two feet ofwatar
due to high groundwaterand rain entering the stonnwatersystem. Some ofthese locations are in residential neighborhoods, and some are along major
streets within the CityAt each location, traffic flow is impeded, and pedestrian flow is unsafe and almost impossible.
Treatment Performance. The stonnwatertreatment system should be sized to meetthe permit discharge requirements ofa trubidiyof no more than 29 NTU
greater than the background turbidityin the bayand 40 mgfl TSS atthe pumping flow rate required. The 2.55 M HOPE Downstream Defender has the
treatment capabilities mandate bypernitforthe small footprint needed for space constraints.
Flow Capacity Public Works has determined through wperienoe that a pumping rate of appro)dmaley 1,500 GPM is required to preventflooding in the areas
ofconoem. his therefore critical that anystonnwatertreahnentsystem have a full treatmentcapaaywith overflow ofat leastthis flow rate or some ofthe
slormwaterwill be discharged withouttreat ment The 2.55 M HOPE Downstream Defender can meet the treatment mandated bypermit at 1,500 GPMflow
rates.
Materials of Construction. Since the stormwatertreatment system will be used above ground and moved everyyear, the materials ofconstruction ofthe
treatmentsystam need to be verystrong, resistanttD heat and sunlighland atthe same time lightweightto be able to deployonsite every6 months. The
Public Works Department has determined that the best material ofoonstruction for this site is HOPE because it meets all these criteria. The Downstream
Defender is manufactures in HOPE material for these applications.
No Power Required.All sites do not have easyaccess to power. Bringing in temporarypower or utilizing a separate generetorwould cause additional safety
and logistic concerns and forthis reason Public Works has determined that one ofthe constraints ofthe treatment system is thatitcannot require power. The

Beach.
This notice is released pursuant to Section 2-367 (d) of the Miami Beach City Code. The purpose of
this notice is to notify interested parties that pursuant to Section 2-367 (d), of the Miami Beach City
Code, that the City intends to make a non-competitive award for the goods or services, as stated
below, available only from a single source.
Goods or services required:
1. Currently, the Public Works Department is seeking to obtain four 2.55 M HDPE Downstream
Defender System. Each DownStream Defender System shall include internals installed in a
2.55 M Diameter HDPE manhole reinforced for above -ground use. The 2.55 M HPDE DD is
estimated to remove 95% of particles down to 175 microns at 1500 GPM.
2. The HDPE Downstream Defender Systems will be installed at four locations within the City of
Miami Beach ("City") flooding with as much as two feet of water due to high groundwater and
rain entering the stormwater system. Some of these locations are in residential neighborhoods,
and some are along major streets within the City. At each location, traffic flow is impeded, and
pedestrian flow is unsafe and almost impossible.
3. Treatment Performance. The stormwater treatment system should be sized to meet the
permit discharge requirements of a turbidity of no more than 29 NTU greater than the
background turbidity in the bay and 40 mg/I TSS at the pumping flow rate required. The 2.55
M HDPE Downstream Defender has the treatment capabilities mandate by permit for the small
footprint needed for space constraints.
4. Flow Capacity. Public Works has determined through experience that a pumping rate of
approximately 1,500 GPM is required to prevent flooding in the areas of concern. It is therefore
critical that any stormwater treatment system have a full treatment capacity with overflow of at
least this flow rate or some of the stormwater will be discharged without treatment. The 2.55 M
HDPE Downstream Defender can meet the treatment mandated by permit at 1,500 GPM flow
rates.
5. Materials of Construction. Since the stormwater treatment system will be used above ground
and moved every year, the materials of construction of the treatment system need to be very
strong, resistant to heat and sunlight and at the same time light weight to be able to deploy
onsite every 6 months. The Public Works Department has determined that the best material of
construction for this site is HDPE because it meets all these criteria. The Downstream Defender
is manufactures in HDPE material for these applications.
6. No Power Required. All sites do not have easy access to power. Bringing in temporary power
or utilizing a separate generator would cause additional safety and logistic concerns and for
this reason Public Works has determined that one of the constraints of the treatment system
Paget of 3
Page 340 of 991
is that it cannot require power. The 2.55 M HDPE Downstream Defender requires no power or
moving parts for stormwater treatment.
7. No Water Required. Most of the sites do not have easy access to either potable or reuse
water. Since temporary water lines would be difficult to implement and subject to vandalism
and even to potential potable water system contamination, Public Works has determined that
one of the constraints of the treatment system is that it cannot require an outside water source.
The 2.55 M HDPE Downstream Defender requires no water for stormwater treatment.
8. Vac Truck Accessible. The Public Works Department owns several vac trucks which are
currently used for other purposes including pumping out manholes, pumping, and maintenance
of existing below -ground DownStream Defenders.
9. Flexible and Mobile. The treatment units will need to be put in place every year prior to the
wet season and removed once the wet season is over. The units will then be moved to the
Public Works Yard and stored until the next season. Additionally, the treatment systems will
need to be relocated around the City from time to time as the need for pumping the stormwater
changes within the City. They may also occasionally be used as a treatment for temporary
dewatering on various projects throughout the City. All of these uses require a stormwater
treatment that can be loaded onto a truck with a fork truck and moved around the streets of the
City by Public Works service personnel without the use of a crane or other specialized
equipment. The 2.55 M HDPE Downstream Defender is lightweight and easy to transport unlike
other solutions available in the market.
10. Footprint. Several of the treatment systems will need to be located in major streets essentially
taking up no more than a parking space and, in some cases, partially blocking a lane of traffic.
For this reason, a small footprint is absolutely critical. A treatment system that is too large or
requires excess maintenance would be a potential safety concern to motorists and to Public
Works Staff. The 2.55 M HDPE Downstream Defender requires no more than half a parking
spot. The DownStream Defender is the perfect device for this application because it is made
from structurally re -enforced HDPE, resistant to heat and sunlight and is light enough to be
easily moved in a temporary application for use during the wet season. The HDPE Downstream
Defenders will be moved into position and will occupy approximately '/Z of a parking spot for
the wet season, then removed and put into storage during the off season. They are flexible
enough to be moved to any application in the City where treatment is required by City staff with
existing city equipment and could even be mounted on a small trailer and moved around the
City on a regular basis if desired. Additionally, Miami Beach already has multiple successfully
installed DownStream Defenders which have been on place for years, and Public Works is
familiar with the performance and cleaning associated with them.
Supplier to be awarded: Hydro International
Reason for Sole Source: Hydro International has provided a sole source letter to the City of Miami
Beach to certify that in the State of Florida, the 2.55 M HDPE Downstream Defender System is only
offered directly through Hydro International and not through manufacturer representatives or
distributors. Therefore, Hydro International is the only vendor that is able to provide the City with the
2.55 M HDPE Downstream Defender System. The Downstream Defender System offers the
stormwater vortex separation device and is the only advanced vortex separator on the market without
an internal bypass mechanism, meaning that 100% of the stormwater inflow entering the system is
treated, ensuring maximum removal of pollutants. It is the only above -ground structurally re -enforced
HDPE vortex separation stormwater treatment system available that can meet the treatment within the
required footprint. The DownStream Defender is also the only HDPE above -ground vortex separator
without a by-pass and with a large enough capacity and adequate performance to handle this project.
The DownStream Defender is unique in that it provides a very high level of stormwater treatment in a
very small above -ground footprint of about half of a car parking spot which is extremely important since
some will be used on the main streets during tourist season.
