Corporate HistoryS t r e s c o n P i p e D i v i s i o n
Introduction 3
Corporate History
STRESCON LIMITED began operations in 1963 by establishing a precast concrete plant in Saint John, New
Brunswick. Strescon was the first company to introduce a wide range of precast concrete products in the
Atlantic Region. A variety of projects were successfully completed in the company’s initial years using both
structural and architectural precast concrete products. Over time, Strescon has developed a reputation for
quality, reliability and service in the industry.
STRESCON LIMITED added concrete pipe and manholes to its list of products in 1972. It established the
CONCRETE PIPE DIVISION in Saint John, New Brunswick to carry a complete line of finished products ready
for delivery. A new, state-of-the-art pipe plant was opened in 2001 which has greatly expanded production
capabilities, both in sizes and quantities of products available.
STRESCON LIMITED expanded operations to Bedford, Nova Scotia in 1978, opening a modern precast plant to
service the area with a full range of products.
STRESCON LIMITED has grown to become the largest precast prestressed concrete manufacturer in Eastern
Canada, marketing its products throughout the four Canadian Atlantic Provinces and the New England Region
of the United States.

Pipe Jointing ProceduresFor Single Offset Gaskets
PipeP14
Joints on smaller pipe, up to 24"diameter, usually can be barredhome. Place a block of woodacross the invert of the pipe toprotect the bell. When thesubgrade is not firm enough toallow barring, the use of a come-along may be necessary to pullthe joint home. This methodshould be used for larger pipe.
Granular material should beplaced up to the spring lineover the entire length of thepipe.
Use of a machine to push thepipe home or to push pipedown to grade can putexcessive pressure on pipecausing it to break or crack.
Improper bedding can causethe pipe to be forced out ofalignment when backfilled.
FOLLOW THESE INSTRUCTIONS
TO PREVENT THESE PROBLEMS
A hole must be dug in the sub-base to accommodate the bell.
When coupling pipe, alignspigot of pipe with bell ofpipe previously laid. Pipeshould be aligned so thegasket is in contact with theflared bell surface aroundthe entire circumference.
Failure to dig a bell hole cancause beam breaks or cracksin the barrel of the pipe.
If bell and spigot are not levelor carefully aligned, thegasket will fish mouthcausing a leak or splitting thebell.

NOTES: 1) The BELL and SPIGOT must be cleaned prior to
assembling each unit (see page P13).
2) The SINGLE OFFSET GASKET must be placed as per manufacturer’s recommendations around the spigot end of the pipe. The gasket must be placed tight to the spigot step. (See page P13)
3) Each unit must be placed squarely on top of the other to prevent the gasket from unseating itself and damaging the unit.

Box CulvertsAdvantages of Using Box Culverts
Box Culverts
FAST EASY INSTALLATIONQuick to install... a typical precast installation can be made in less than a day. This keeps the project comple-
tion time at a minimum and the job costs in line. This ends unnecessarily long road closings, traffic disrup-
tions and reroutings.
PRODUCT VERSATILITYPrecast box units are custom made to fit your needs in a wide variety of sizes to meet specialized project
requirements. Custom box units such as radius, transition, bent, skewed and angled end units are available.
MULTIPLE BOX SPANSCan be achieved by installing two or more rows of box units parallel to each other.
NO COVER REQUIREDFlat top surface can accommodate placing the road directly on the structure (zero cover). This feature elimi-
nates or minimizes backfill requirements. Normal backfill procedures are acceptable. No additional lateral
restraint from the backfill is required.
QUALITY CONTROLPlant fabrication of box units under carefully controlled conditions assures a consistent high quality product.
As a result you receive a factory-inspected product, ready to install immediately upon arrival at the jobsite.
Your installation moves ahead of schedule with no sacrifice in quality or strength due to adverse weather
conditions.
OTHER APPLICATIONSVersatile box units can be used as utility and pedestrian tunnels. They can also be installed on their end for
use as small enclosures or storage tanks with precast or cast-in-place concrete bottoms.

1. About Stormceptor The Stormceptor® (Standard Treatment Cell) was developed by Imbrium™ Systems to address the growing need to remove and isolate pollution from the storm drain system before it enters the environment. The Stormceptor STC targets hydrocarbons and total suspended solids (TSS) in stormwater runoff. It improves water quality by removing contaminants through the gravitational settling of fine sediments and floatation of hydrocarbons while preventing the re-suspension or scour of previously captured pollutants. The development of the Stormceptor STC revolutionized stormwater treatment, and created an entirely new category of environmental technology. Protecting thousands of waterways around the world, the Stormceptor System has set the standard for effective stormwater treatment.

2. Stormceptor Design Overview
2.1. Design Philosophy The patented Stormceptor System has been designed focus on the environmental objective of providing long-term pollution control. The unique and innovative Stormceptor design allows for continuous positive treatment of runoff during all rainfall events, while ensuring that all captured pollutants are retained within the system, even during intense storm events. An integral part of the Stormceptor design is PCSWMM for Stormceptor - sizing software developed in conjunction with Computational Hydraulics Inc. (CHI) and internationally acclaimed expert, Dr. Bill James. Using local historical rainfall data and continuous simulation modeling, this software allows a Stormceptor unit to be designed for each individual site and the corresponding water quality objectives.
Technical Manual
3
By using PCSWMM for Stormceptor, the Stormceptor System can be designed to remove a wide range of particles (typically from 20 to 2,000 microns), and can also be customized to remove a specific particle size distribution (PSD). The specified PSD should accurately reflect what is in the stormwater runoff to ensure the device is achieving the desired water quality objective. Since stormwater runoff contains small particles (less than 75 microns), it is important to design a treatment system to remove smaller particles in addition to coarse particles.
2.2. Benefits The Stormceptor System removes free oil and suspended solids from stormwater, preventing spills and non-point source pollution from entering downstream lakes and rivers. The key benefits, capabilities and applications of the Stormceptor System are as follows: • Provides continuous positive treatment during all rainfall events • Can be designed to remove over 80% of the annual sediment load • Removes a wide range of particles • Can be designed to remove a specific particle size distribution (PSD) • Captures free oil from stormwater • Prevents scouring or re-suspension of trapped pollutants • Pre-treatment to reduce maintenance costs for downstream treatment measures (ponds,
swales, detention basins, filters) • Groundwater recharge protection • Spills capture and mitigation • Simple to design and specify • Designed to your local watershed conditions • Small footprint to allow for easy retrofit installations • Easy to maintain (vacuum truck) • Multiple inlets can connect to a single unit • Suitable as a bend structure • Pre-engineered for traffic loading (minimum CHBDC) • Minimal elevation drop between inlet and outlet pipes • Small head loss • Additional protection provided by an 18” (457 mm) fiberglass skirt below the top of the
insert, for the containment of hydrocarbons in the event of a spill.
2.3. Environmental Benefit Freshwater resources are vital to the health and welfare of their surrounding communities. There is increasing public awareness, government regulations and corporate commitment to reducing the pollution entering our waterways. A major source of this pollution originates from stormwater runoff from urban areas. Rainfall runoff carries oils, sediment and other contaminants from roads and parking lots discharging directly into our streams, lakes and coastal waterways. The Stormceptor System is designed to isolate contaminants from getting into the natural environment. The Stormceptor technology provides protection for the environment from spills that occur at service stations and vehicle accident sites, while also removing contaminated sediment in runoff that washes from roads and parking lots.

3. Key Operation Features
3.1. Scour Prevention A key feature of the Stormceptor System is its patented scour prevention technology. This innovation ensures pollutants are captured and retained during all rainfall events, even extreme storms. The Stormceptor System provides continuous positive treatment for all rainfall events, including intense storms. Stormceptor slows incoming runoff, controlling and reducing velocities in the lower chamber to create a non-turbulent environment that promotes free oils and floatable debris to rise and sediment to settle. The patented scour prevention technology, the fiberglass insert, regulates flows into the lower chamber through a combination of a weir and orifice while diverting high energy flows away through the upper chamber to prevent scouring. Laboratory testing demonstrated no scouring when tested up to 125% of the unit’s operating rate, with the unit loaded to 100% sediment capacity (NJDEP, 2005). Second, the depth of the lower chamber ensures the sediment storage zone is adequately separated from the path of flow in the lower chamber to prevent scouring.
3.2. Operational Hydraulic Loading Rate Designers and regulators need to evaluate the treatment capacity and performance of manufactured stormwater treatment systems. A commonly used parameter is the “operational hydraulic loading rate” which originated as a design methodology for wastewater treatment devices. Operational hydraulic loading rate may be calculated by dividing the flow rate into a device by its settling area. This represents the critical settling velocity that is the prime determinant to quantify the influent particle size and density captured by the device. PCSWMM for Stormceptor uses a similar parameter that is calculated by dividing the hydraulic detention time in the device by the fall distance of the sediment.
SHSC A
QHv ==θ
Where: SCv = critical settling velocity, ft/s (m/s) H = tank depth, ft (m) Hθ = hydraulic detention time, ft/s (m/s) Q = volumetric flow rate, ft3/s (m3/s)
SA = surface area, ft2 (m2) (Tchobanoglous, G. and Schroeder, E.D. 1987. Water Quality. Addison Wesley.) Unlike designing typical wastewater devices, stormwater systems are designed for highly variable flow rates including intense peak flows. PCSWMM for Stormceptor incorporates all of the flows into its calculations, ensuring that the operational hydraulic loading rate is considered not only for one flow rate, but for all flows including extreme events.
Technical Manual

3.3. Double Wall Containment The Stormceptor System was conceived as a pollution identifier to assist with identifying illicit discharges. The fiberglass insert has a continuous skirt that lines the concrete barrel wall for a depth of 18 inches (406 mm) that provides double wall containment for hydrocarbons storage. This protective barrier ensures that toxic floatables do not migrate through the concrete wall and the surrounding soils.

NOTE: Storage volumes may vary slightly from region to region. For detailed information, contact your local Stormceptor representative.
4.2. Inline Stormceptor The Inline Stormceptor, Figure 1, is the standard design for most stormwater treatment applications. The patented Stormceptor design allows the Inline unit to maintain continuous positive treatment of total suspended solids (TSS) year-round, regardless of flow rate. The Inline Stormceptor is composed of a precast concrete tank with a fiberglass insert situated at the invert of the storm sewer pipe, creating an upper chamber above the insert and a lower chamber below the insert.

Figure 1. Inline Stormceptor Operation As water flows into the Stormceptor unit, it is slowed and directed to the lower chamber by a weir and drop tee. The stormwater enters the lower chamber, a non-turbulent environment, allowing free oils to rise and sediment to settle. The oil is captured underneath the fiberglass insert and shielded from exposure to the concrete walls by a fiberglass skirt. After the pollutants separate, treated water continues up a riser pipe, and exits the lower chamber on the downstream side of the weir before leaving the unit. During high flow events, the Stormceptor System’s patented scour prevention technology ensures continuous pollutant removal and prevents re-suspension of previously captured pollutants.
4.3. Inlet Stormceptor The Inlet Stormceptor System, Figure 2, was designed to provide protection for parking lots, loading bays, gas stations and other spill-prone areas. The Inlet Stormceptor is designed to remove sediment from stormwater introduced through a grated inlet, a storm sewer pipe, or both.

5. Sizing the Stormceptor System The Stormceptor System is a versatile product that can be used for many different aspects of water quality improvement. While addressing these needs, there are conditions that the designer needs to be aware of in order to size the Stormceptor model to meet the demands of each individual site in an efficient and cost-effective manner. PCSWMM for Stormceptor is the support tool used for identifying the appropriate Stormceptor model. In order to size a unit, it is recommended the user follow the seven design steps in the program. The steps are as follows: STEP 1 – Project Details The first step prior to sizing the Stormceptor System is to clearly identify the water quality objective for the development. It is recommended that a level of annual sediment (TSS) removal be identified and defined by a particle size distribution.
Technical Manual
9
STEP 2 – Site Details Identify the site development by the drainage area and the level of imperviousness. It is recommended that imperviousness be calculated based on the actual area of imperviousness based on paved surfaces, sidewalks and rooftops. STEP 3 – Upstream Attenuation The Stormceptor System is designed as a water quality device and is sometimes used in conjunction with onsite water quantity control devices such as ponds or underground detention systems. When possible, a greater benefit is typically achieved when installing a Stormceptor unit upstream of a detention facility. By placing the Stormceptor unit upstream of a detention structure, a benefit of less maintenance of the detention facility is realized. STEP 4 – Particle Size Distribution It is critical that the PSD be defined as part of the water quality objective. PSD is critical for the design of treatment system for a unit process of gravity settling and governs the size of a treatment system. A range of particle sizes has been provided and it is recommended that clays and silt-sized particles be considered in addition to sand and gravel-sized particles. Options and sample PSDs are provided in PCSWMM for Stormceptor. The default particle size distribution is the Fine Distribution, Table 2, option.
Table 2. Fine Distribution
Particle Size Distribution Specific Gravity
20 20% 1.3 60 20% 1.8
150 20% 2.2 400 20% 2.65
2000 20% 2.65 If the objective is the long-term removal of 80% of the total suspended solids on a given site, the PSD should be representative of the expected sediment on the site. For example, a system designed to remove 80% of coarse particles (greater than 75 microns) would provide relatively poor removal efficiency of finer particles that may be naturally prevalent in runoff from the site. Since the small particle fraction contributes a disproportionately large amount of the total available particle surface area for pollutant adsorption, a system designed primarily for coarse particle capture will compromise water quality objectives. STEP 5 – Rainfall Records Local historical rainfall has been acquired from the U.S. National Oceanic and Atmospheric Administration, Environment Canada and regulatory agencies across North America. The rainfall data provided with PCSMM for Stormceptor provides an accurate estimation of small storm hydrology by modeling actual historical storm events including duration, intensities and peaks.

STEP 6 – Summary At this point, the program may be executed to predict the level of TSS removal from the site. Once the simulation has completed, a table shall be generated identifying the TSS removal of each Stormceptor unit. STEP 7 – Sizing Summary Performance estimates of all Stormceptor units for the given site parameters will be displayed in a tabular format. The unit that meets the water quality objective, identified in Step 1, will be highlighted.
5.1. PCSWMM for Stormceptor The Stormceptor System has been developed in conjunction with PCSWMM for Stormceptor as a technological solution to achieve water quality goals. Together, these two innovations model, simulate, predict and calculate the water quality objectives desired by a design engineer for TSS removal. PCSWMM for Stormceptor is a proprietary sizing program which uses site specific inputs to a computer model to simulate sediment accumulation, hydrology and long-term total suspended solids removal. The model has been calibrated to field monitoring results from Stormceptor units that have been monitored in North America. The sizing methodology can be described by three processes:
1. Determination of real time hydrology 2. Buildup and wash off of TSS from impervious land areas 3. TSS transport through the Stormceptor (settling and discharge) The use of a
calibrated model is the preferred method for sizing stormwater quality structures for the following reasons: a. The hydrology of the local area is properly and accurately incorporated in the
sizing (distribution of flows, flow rate ranges and peaks, back-to-back storms, inter-event times)
b. The distribution of TSS with the hydrology is properly and accurately considered in the sizing
c. Particle size distribution is properly considered in the sizing d. The sizing can be optimized for TSS removal e. The cost benefit of alternate TSS removal criteria can be easily assessed f. The program assesses the performance of all Stormceptor models. Sizing may be
selected based on a specific water quality outcome or based on the Maximum Extent Practicable
For more information regarding PCSWMM for Stormceptor, contact your local Stormceptor representative, or visit www.imbriumsystems.com to download a free copy of the program.
5.2. Sediment Loading Characteristics The way in which sediment is transferred to stormwater can have a considerable effect on which type of system is implemented. On typical impervious surfaces (e.g. parking lots) sediment will build over time and wash off with the next rainfall. When rainfall patterns are
Technical Manual
11
examined, a short intense storm will have a higher concentration of sediment than a long slow drizzle. Together with rainfall data representing the site’s typical rainfall patterns, sediment loading characteristics play a part in the correct sizing of a stormwater quality device. Typical Sites
For standard site design of the Stormceptor System, PCSWMM for Stormceptor is utilized to accurately assess the unit’s performance. As an integral part of the product’s design, the program can be used to meet local requirements for total suspended solid removal. Typical installations of manufactured stormwater treatment devices would occur on areas such as paved parking lots or paved roads. These are considered “stable” surfaces which have non –erodible surfaces. Unstable Sites
While standard sites consist of stable concrete or asphalt surfaces, sites such as gravel parking lots, or maintenance yards with stockpiles of sediment would be classified as “unstable”. These types of sites do not exhibit first flush characteristics, are highly erodible and exhibit atypical sediment loading characteristics and must therefore be sized more carefully. Contact your local Stormceptor representative for assistance in selecting proper unit size for such unstable sites.
6. Spill Controls When considering the removal of total petroleum hydrocarbons (TPH) from a storm sewer system there are two functions of the system: oil removal, and spill capture. 'Oil Removal' describes the capture of the minute volumes of free oil mobilized from impervious surfaces. In this instance relatively low concentrations, volumes and flow rates are considered. While the Stormceptor unit will still provide an appreciable oil removal function during higher flow events and/or with higher TPH concentrations, desired effluent limits may be exceeded under these conditions. 'Spill Capture' describes a manner of TPH removal more appropriate to recovery of a relatively high volume of a single phase deleterious liquid that is introduced to the storm sewer system over a relatively short duration. The two design criteria involved when considering this manner of introduction are overall volume and the specific gravity of the material. A standard Stormceptor unit will be able to capture and retain a maximum spill volume and a minimum specific gravity. For spill characteristics that fall outside these limits, unit modifications are required. Contact your local Stormceptor Representative for more information. One of the key features of the Stormceptor technology is its ability to capture and retain spills. While the standard Stormceptor System provides excellent protection for spill control, there are additional options to enhance spill protection if desired.
6.1. Oil Level Alarm The oil level alarm is an electronic monitoring system designed to trigger a visual and audible alarm when a pre-set level of oil is reached within the lower chamber. As a standard, the oil
Return to Main IndexReturn to STORMCEPTOR® table of contents
Technical Manual
12
level alarm is designed to trigger at approximately 85% of the unit’s available depth level for oil capture. The feature acts as a safeguard against spills caused by exceeding the oil storage capacity of the separator and eliminates the need for manual oil level inspection. The oil level alarm installed on the Stormceptor insert is illustrated in Figure 4.

6.2. Increased Volume Storage Capacity The Stormceptor unit may be modified to store a greater spill volume than is typically available. Under such a scenario, instead of installing a larger than required unit, modifications can be made to the recommended Stormceptor model to accommodate larger volumes. Contact your local Stormceptor representative for additional information and assistance for modifications.
7. Stormceptor Options The Stormceptor System allows flexibility to incorporate to existing and new storm drainage infrastructure. The following section identifies considerations that should be reviewed when installing the system into a drainage network. For conditions that fall outside of the recommendations in this section, please contact your local Stormceptor representative for further guidance.
7.1. Installation Depth / Minimum Cover The minimum distance from the top of grade to the crown of the inlet pipe is 24 inches (600 mm). For situations that have a lower minimum distance, contact your local Stormceptor representative.
7.2. Maximum Inlet and Outlet Pipe Diameters Maximum inlet and outlet pipe diameters are illustrated in Figure 5. Contact your local Stormceptor representative for larger pipe diameters.

7.3. Bends The Stormceptor System can be used to change horizontal alignment in the storm drain network up to a maximum of 90 degrees. Figure 6 illustrates the typical bend situations for the Stormceptor System. Bends should only be applied to the second structure (downstream structure) of the Series Stormceptor System.

7.4. Multiple Inlet Pipes The Inlet and Inline Stormceptor System can accommodate two or more inlet pipes. The maximum number of inlet pipes that can be accommodated into a Stormceptor unit is a function of the number, alignment and diameter of the pipes and its effects on the structural integrity of the precast concrete. When multiple inlet pipes are used for new developments, each inlet pipe shall have an invert elevation 3 inches (75 mm) higher than the outlet pipe invert elevation.
7.5. Inlet/Outlet Pipe Invert Elevations Recommended inlet and outlet pipe invert differences are listed in Table 3.

7.6. Shallow Stormceptor In cases where there may be restrictions to the depth of burial of storm sewer systems. In this situation, for selected Stormceptor models, the lower chamber components may be increased in diameter to reduce the overall depth of excavation required.
7.7. Customized Live Load The Stormceptor system is typically designed for local highway truck loading (HS-20 in the US and CHBDC in Canada). In instances of other loads, the Stormceptor System may be customized structurally for a pre-specified live load. Contact your local Stormceptor representative for customized loading conditions.
7.8. Pre-treatment The Stormceptor System may be sized to remove sediment and for spills control in conjunction with other stormwater BMPs to meet the water quality objective. For pretreatment applications, the Stormceptor System should be the first unit in a treatment train. The benefits of pre-treatment include the extension of the operational life (extension of maintenance frequency) of large stormwater management facilities, prevention of spills and lower total life-cycle maintenance cost.
7.9. Head loss The head loss through the Stormceptor System is similar to a 60 degree bend at a maintenance hole. The K value for calculating minor losses is approximately 1.3 (minor loss = k*1.3v2/2g). However, when a Submerged modification is applied to a Stormceptor unit, the corresponding K value is 4.
7.10. Submerged The Submerged modification, Figure 7, allows the Stormceptor System to operate in submerged or partially submerged storm sewers. This configuration can be installed on all models of the Stormceptor System by modifying the fiberglass insert. A customized weir height and a secondary drop tee are added. Submerged instances are defined as standing water in the storm drain system during zero flow conditions. In these instances, the following information is necessary for the proper design and application of submerged modifications:
• Stormceptor top of grade elevation • Stormceptor outlet pipe invert elevation • Standing water elevation

8. Comparing Technologies Designers have many choices available to achieve water quality goals in the treatment of stormwater runoff. Since many alternatives are available for use in stormwater quality treatment it is important to consider how to make an appropriate comparison between “approved alternatives”. The following is a guide to assist with the accurate comparison of differing technologies and performance claims.
8.1. Particle Size Distribution (PSD) The most sensitive parameter to the design of a stormwater quality device is the selection of the design particle size. While it is recommended that the actual particle size distribution (PSD) for sites be measured prior to sizing, alternative values for particle size should be selected to represent what is likely to occur naturally on the site. A reasonable estimate of a particle size distribution likely to be found on parking lots or other impervious surfaces should consist of a wide range of particles such as 20 microns to 2,000 microns (Ontario MOE, 1994). There is no absolute right particle size distribution or specific gravity and the user is cautioned to review the site location, characteristics, material handling practices and regulatory requirements when selecting a particle size distribution. When comparing technologies, designs using different PSDs will result in incomparable TSS removal
Technical Manual
17
efficiencies. The PSD of the TSS removed needs to be standard between two products to allow for an accurate comparison.
8.2. Scour Prevention In order to accurately predict the performance of a manufactured treatment device, there must be confidence that it will perform under all conditions. Since rainfall patterns cannot be predicted, stormwater quality devices placed in storm sewer systems must be able to withstand extreme events, and ensure that all pollutants previously captured are retained in the system. In order to have confidence in a system’s performance under extreme conditions, independent validation of scour prevention is essential when examining different technologies. Lack of independent verification of scour prevention should make a designer wary of accepting any product’s performance claims.
8.3. Hydraulics Full scale laboratory testing has been used to confirm the hydraulics of the Stormceptor
System. Results of lab testing have been used to physically design the Stormceptor System and the sewer pipes entering and leaving the unit. Key benefits of Stormceptor are:
• Low head loss (typical k value of 1.3) • Minimal inlet/outlet invert elevation drop across the structure • Use as a bend structure • Accommodates multiple inlets
The adaptability of the treatment device to the storm sewer design infrastructure can affect the overall performance and cost of the site.
8.4. Hydrology Stormwater quality treatment technologies need to perform under varying climatic conditions. These can vary from long low intensity rainfall to short duration, high intensity storms. Since a treatment device is expected to perform under all these conditions, it makes sense that any system’s design should accommodate those conditions as well. Long-term continuous simulation evaluates the performance of a technology under the varying conditions expected in the climate of the subject site. Single, peak event design does not provide this information and is not equivalent to long-term simulation. Designers should request long-term simulation performance to ensure the technology can meet the long-term water quality objective.

9. Testing The Stormceptor System has been the most widely monitored stormwater treatment technology in the world. Performance verification and monitoring programs are completed to the strictest standards and integrity. Since its introduction in 1990, numerous independent field tests and studies detailing the effectiveness of the Stormceptor System have been completed.
• Coventry University, UK – 97% removal of oil, 83% removal of sand and 73% removal of peat
• National Water Research Institute, Canada, - scaled testing for the development of the Stormceptor System identifying both TSS removal and scour prevention.
• New Jersey TARP Program – full scale testing of an STC 750/900 demonstrating 75% TSS removal of particles from 1 to 1000 microns. Scour testing completed demonstrated that the system does not scour. The New Jersey Department of Environmental Protection laboratory testing protocol was followed.
• City of Indianapolis – full scale testing of an STC 750/900 demonstrating over 80% TSS removal of particles from 50 microns to 300 microns at 130% of the unit’s operating rate. Scour testing completed demonstrated that the system does not scour.
• Westwood Massachusetts (1997), demonstrated >80% TSS removal • Como Park (1997), demonstrated 76% TSS removal • Ontario MOE SWAMP Program – 57% removal of 1 to 25 micron particles • Laval Quebec – 50% removal of 1 to 25 micron particles
10. Installation The installation of the concrete Stormceptor should conform in general to state highway, provincial or local specifications for the installation of maintenance holes. Selected sections of a general specification that are applicable are summarized in the following sections.
10.1. Excavation Excavation for the installation of the Stormceptor should conform to state highway, provincial or local specifications. Topsoil removed during the excavation for the Stormceptor should be stockpiled in designated areas and should not be mixed with subsoil or other materials. Topsoil stockpiles and the general site preparation for the installation of the Stormceptor should conform to state highway, provincial or local specifications. The Stormceptor should not be installed on frozen ground. Excavation should extend a minimum of 12 inches (300mm) from the precast concrete surfaces plus an allowance for shoring and bracing where required. If the bottom of the excavation provides an unsuitable foundation additional excavation may be required. In areas with a high water table, continuous dewatering may be required to ensure that the excavation is stable and free of water.
Technical Manual
19
10.2. Backfilling Backfill material should conform to state highway, provincial or local specifications. Backfill material should be placed in uniform layers not exceeding 12 inches (300mm) in depth and compacted to state highway, provincial or local specifications.
11. Stormceptor Construction Sequence The concrete Stormceptor is installed in sections in the following sequence:
1. Aggregate base 2. Base slab 3. Lower chamber sections 4. Upper chamber section with fiberglass insert 5. Connect inlet and outlet pipes 6. Assembly of fiberglass insert components (drop tee, riser pipe, oil cleanout port
and orifice plate 7. Remainder of upper chamber 8. Frame and access cover
The precast base should be placed level at the specified grade. The entire base should be in contact with the underlying compacted granular material. Subsequent sections, complete with joint seals, should be installed in accordance with the precast concrete manufacturer’s recommendations. Adjustment of the Stormceptor can be performed by lifting the upper sections free of the excavated area, re-leveling the base and re-installing the sections. Damaged sections and gaskets should be repaired or replaced as necessary. Once the Stormceptor has been constructed, any lift holes must be plugged with mortar.
12. Maintenance
12.1. Health and Safety The Stormceptor System has been designed considering safety first. It is recommended that confined space entry protocols be followed if entry to the unit is required. In addition, the fiberglass insert has the following health and safety features:
• Designed to withstand the weight of personnel • A safety grate is located over the 24 inch (600 mm) riser pipe opening • Ladder rungs are provided for entry into the unit, if required
12.2. Maintenance Procedures Maintenance of the Stormceptor system is performed using vacuum trucks. No entry into the unit is required for maintenance (in most cases). The vacuum service industry is a well-established sector of the service industry that cleans underground tanks, sewers and catch basins. Costs to clean a Stormceptor will vary based on the size of unit and transportation distances. The need for maintenance can be determined easily by inspecting the unit from the surface. The depth of oil in the unit can be determined by inserting a dipstick in the oil inspection/cleanout port.
Return to Main IndexReturn to STORMCEPTOR® table of contents
Technical Manual
20
Similarly, the depth of sediment can be measured from the surface without entry into the Stormceptor via a dipstick tube equipped with a ball valve. This tube would be inserted through the riser pipe. Maintenance should be performed once the sediment depth exceeds the guideline values provided in the table 4.
Table 4. Sediment Depths indicating required servicing.
Sediment Depths Indicating Required Servicing *
Model (CAN) Sediment Depth inches (mm)
300i 9 (225) 750 9 (230)
1000 11 (275) 1500 16 (400) 2000 14 (350) 3000 19 (475) 4000 16 (400) 5000 20 (500) 6000 17 (425) 9000 16 (400) 10000 20 (500) 14000 17 (425)
* based on 15% of the Stormceptor unit’s total storage Although annual servicing is recommended, the frequency of maintenance may need to be increased or reduced based on local conditions (i.e. if the unit is filling up with sediment more quickly than projected, maintenance may be required semi-annually; conversely once the site has stabilized maintenance may only be required every two or three years). Oil is removed through the oil inspection/cleanout port and sediment is removed through the riser pipe. Alternatively oil could be removed from the 24 inches (600 mm) opening if water is removed from the lower chamber to lower the oil level below the drop pipes. The following procedures should be taken when cleaning out Stormceptor:
1. Check for oil through the oil cleanout port 2. Remove any oil separately using a small portable pump 3. Decant the water from the unit to the sanitary sewer, if permitted by the local
regulating authority, or into a separate containment tank 4. Remove the sludge from the bottom of the unit using the vacuum truck 5. Re-fill Stormceptor with water where required by the local jurisdiction
Technical Manual
21
12.3. Submerged Stormceptor Careful attention should be paid to maintenance of the Submerged Stormceptor System. In cases where the storm drain system is submerged, there is a requirement to plug both the inlet and outlet pipes to economically clean out the unit.
12.4. Hydrocarbon Spills The Stormceptor is often installed in areas where the potential for spills is great. The Stormceptor System should be cleaned immediately after a spill occurs by a licensed liquid waste hauler.
12.5. Disposal Requirements for the disposal of material from the Stormceptor System are similar to that of any other stormwater Best Management Practice (BMP) where permitted. Disposal options for the sediment may range from disposal in a sanitary trunk sewer upstream of a sewage treatment plant, to disposal in a sanitary landfill site. Petroleum waste products collected in the Stormceptor (free oil/chemical/fuel spills) should be removed by a licensed waste management company.
12.6. Oil Sheens With a steady influx of water with high concentrations of oil, a sheen may be noticeable at the Stormceptor outlet. This may occur because a rainbow or sheen can be seen at very small oil concentrations (<10 ppm). Stormceptor will remove over 98% of all free oil spills from storm sewer systems for dry weather or frequently occurring runoff events. The appearance of a sheen at the outlet with high influent oil concentrations does not mean the unit is not working to this level of removal. In addition, if the influent oil is emulsified the Stormceptor will not be able to remove it. The Stormceptor is designed for free oil removal and not emulsified conditions.

What are ReCon® Retaining Walls?
ReCon® Retaining Wall Systems manufactured and supplied by Strescon Limited, is an industry leader for
aesthetically and structurally superior retaining wall solutions. Their massive size along with unique tongue
and groove design allows taller gravity walls and taller geogrid reinforced walls to be designed. Manufactured
with durable wet cast concrete resistant to the elements, the walls can be quickly constructed due to the
blocks size without requiring large or specialized equipment.
Blocks come in multiple depths to optimize design efficiency and the natural stone finish is aesthetically
pleasing on a scale suited for backyards to commercial developments to the largest of transportation / in-
frastructure projects. Double sided fence blocks, capstones, steps, curves and 90 degree corners can all be
accomplished using the ReCon system to suit the needs of any site.
Features & Benefits
• Large Size and Mass
• Tall Gravity Walls: Unique tongue-and-groove lock-and-placement design, combined with massive size and weight, permits wall heights up to 17 ft. 4 in. (5.28 m) without reinforcing geogrid.
Significantly taller ReCon Walls can be built by incorporating geogrid, setback on teirs.
• Durability: Made of wet-cast, air-entrained concrete. The durability required in environments prone to the challenges of freeze/thaw cycle, road salts or brackish water.
• Faster Installation: Walls can be constructed quickly using equipment generally available to contractors (skid steers or backhoes), maximizing productivity and minimizing manual labour. No mortar, no pins.
• Engineered and Tested: A ReCon Wall can be professionally engineered and designed (using shear and geogrid connection data unique to ReCon) for wall performance that is generally unavailable for natural stone walls.
• Customized Design and Aesthetics: The natural stone finish has several different textures, which pre-vents repetition in the overall wall pattern.
Block comes in mulitple depths, to optimize design efficiency by providing the mass when required or eliminating it when not required to save material and freight cost.
Tapered block design allows both inside and outside 90-degree corners and curves.
Caps or special top units that allow greenscape within four inches of the finished wall’s face are avaiable for top-of-wall finishing options.

lation of concrete pipe, as adopted by the Canadian Highway Bridge Design code, CSA S6-00, OCPA, ASTM and ACPA, is an accepted practice.
3.3 Pipe Installation .1 Lay and joint pipe and fittings as specified herein and according to manufac-turer’s published instructions.
.2 Lay pipe and fittings on prepared bed, true to line and grade indicated within following tolerances:
Horizontal Alignment: the lesser of 13mm or one half the rise per pipe length. .3 Commence laying at outlet and proceed upstream with bell ends facing upgrade. .4 Prevent entry of bedding material, water or other foreign matter into pipe.
Use temporary watertight bulkheads when pipe laying is not in progress. .5 Install gaskets in accordance with manufacturer’s published instructions.
During cold weather, store gaskets in heated area to assure flexibility. .6 Align pipe carefully before joining. Do not use excessive force to join pipe sections. .7 Support pipes as required to assure concentricity until joint is properly completed. .8 Keep pipe joints free from mud, silt, gravel or other foreign material. .9 Avoid displacing gasket or contaminating with dirt, petroleum products or
other foreign material. Remove, clean, reinstall and lubricate (if required) gaskets so disturbed.
.10 Complete each joint before laying next length of pipe. .11 Where deflection at joints is permitted, defect only after the joint is completed.
Do not exceed maximum joint deflection recommended by pipe manufacturer. .12 At structures - provide flexible joint not more than 300mm from outside face
of structure. .13 For corrugated steel pipe - match corrugations or indentation of coupler band
with pipe sections before tightening. Tap coupler firmly while tightening to take up slack and ensure snug fit. Ensure all bolts are inserted and tightened.
.14 Cut pipe as required for fittings or closure pieces, square to centerline and as recommended by manufacturer.
.15 Make watertight connections to manholes and catchbasins. Use non-shrink grout when suitable gaskets are not available.
