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

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.

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.

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.
