on these products.
Sanders & Company
A number of water management products are available from Sanders and
Company, including the Envirobridge, an effective solution for both
temporary and permanent stream and pipeline crossings. The steel
arch bottomless culverts are durable, reusable and fish-friendly and allow
more flexibility for stream and watercourse crossings. The one-piece
construction requires no on-site assembly, installation and removal are
quick and little or no bed preparation is required, the company says. A
20-tonne machine can handle the loading of any of the 7.3-metre pipes. The
use of recycled steel reduces the overall cost of Envirobridge by 40 per
cent. Available in various sizes and profiles, it can be ordered in
virtually any length, width or height. The bridge requires minimal fill
coverage and the end walls contain fill and eliminate spills.
Developed for use on wider streams and crossings without compromising the
strength and integrity of the structure, the Widebody Enviro-Bridge is
strong enough to support a 90,000-lb machine without any fill material and
can be used for temporary or permanent installations, as well as skid and
access bridges. The one-piece bridge comes in two widths, with outside
measurements of approximately 4.3 and 5.3 metres. Inside measurements of
the pipes are approximately 3.3 and 4.3 metres. Standard length is 7.3
metres, but custom orders are available.
Normally installed on bridge or stream crossing approaches, the Enviro
cross road drain eliminates silt flows off road surfaces. It has a
removeable grate for clean-out and removeable end plates. The 60-cm wide
unit is available in any length.

Armtec Construction Products
The high density polyethylene (HDPE) BOSS pipe from Armtec is engineered
for gravity flow systems and offers a distinct weight advantage over
conventional sewer pipe, at less than 10 per cent of the weight of
concrete pipe throughout the range of products. BOSS pipe can be trimmed
to length in seconds, using common cutting tools. Most of the products are
available in both 320 kPa and 210 kPa stiffness.
BOSS POLY-TITE is a CSA-certified, leak-tight sanitary and storm pipe with
a 320 kPa pipe stiffness. Its smooth inner wall provides optimal flow and
unsurpassed resistance to abrasion and corrosion. It offers gasketed bell
and spigot for simple field connection and positive joint integrity.
Impact and weather resistant BOSS 2000 is a CSA-certified storm sewer and
culvert pipe used for storm sewers, perforated storm water management
systems, landfill leachate collection and industrial liquid collection
systems, as well as greenhouse applications. It incorporates the strength
of a corrugated outer shell with a smooth inner wall to optimize flow
capacity. As well, longer lengths and in-line fittings cause less
disturbance to flow than traditional products, the company says. BOSS 2000
offers a minimum crack resistance of 15 per cent tensile yield stress for
24 hours and comes with a full range of moulded fittings and adapters,
including an extensive selection of made-to-order fabricated fittings to
suit special needs.
BOSS 1000 corrugated culvert and storm sewer pipe has a single wall,
corrugated interior which offers excellent flexibility and economy.
Armtec manufactures and distributes BOSS products across Canada.

forestry arch, the new fish-friendly open bottom culvert from
Atlantic Industries Ltd, cost-effectively meets stringent stream
crossing codes. Constructed of aluminum, it is the lightest
short-span bridge on the market, the company says, and can be
transported to the site on a small culvert trailer. The reusable
and salvageable structure can be placed and back-filled in less
than a day. The open bottom concept means the stream bed is left
in its natural state, allowing for unobstructed fish passage. The
length of the arch is adaptable to different sites with 1.37-metre
wide plates. Pre-assembled structures come with installed lifting
hooks and corrugated metal footings. The plates can also be
purchased unassembled and without footings. The L-100 design has a
minimum 600-mm cover. Footings are designed for 200 kPa bearing

evolution of plastics has meant the material is outperforming and
outlasting conventional metals and minerals and the BOSS 1000 and
BOSS 2000 Virgin HDPE culvert pipes are becoming the workhorses of
the road construction industry, says BC manufacturer and
distributor Polytubes Pacific. The rugged HDPE pipes combined with
their corrugated exterior create increased structural strength,
giving them the toughness and flexibility enabling them to
withstand fill heights of up to 30 feet and more, the company
says. BOSS 1000 and BOSS 2000 are engineered for use in both H20
and E80 live loads with fill heights greater than 39 feet. The
lightweight products offer job site savings from ease of handling,
smaller work crews, smaller equipment and increased site safety.
The pipes offer excellent corrosion resistance, with a recommended
pH range of 1.25 to 14, enabling them to outperform metal and
concrete pipes, the company says.
Soleno Pacific Inc
Soleno manufactures environmentally-friendly Solflo-Max, a dual-wall, HDPE
culvert pipe with a distinctive green liner and corrugated exterior for
extra strength. A smooth interior guarantees superior flow, rated at a
manning of "n" 0.010, the company says. With 210 and 320 kPa
rigidity at five per cent deflection, Solflo is also exceptionally
resistant to cold temperature impact, abrasion, corrosion and chemicals.
Used extensively by the forest industry
across Canada, a number of
Soleno products are recognized under the federal government's Terra Choice
Program and certified as "environmental". Soleno has plants
located across Canada.

Iceworm International Inc
The Iceworm culvert thawing system is designed to save time and money by
unplugging culverts that become plugged with ice during winter and spring
thaw seasons. Consisting of an electrical cable, a controller and a power
source, the system can be used in any culvert. The cable is installed
during the summer months in the potentially problem culverts. During
spring breakup, the controller and power source can be easily transported
in a pickup truck and, when ice begins to accumulate, the Iceworm thawing
system can open the culvert in a matter of minutes, the company says. One
operator with a controller/power source can service several dozen culvert
cables. The light, portable and patented system is safe, efficient, cost
effective and environmentally friendly.

RayMac Environmental Services
The Water Guard Kit from RayMac Environmental Services helps prevent the
migration of hydrocarbons and reduces the amount of sediment migrating
from the job site downstream. The kit comes with three, 10'x8"
sections of oil sorbent boom to catch any accidentally
spilled fuels or oil. Utilizing a 15'x15' piece of woven geotextile to act
as a sediment filter, the Water Guard is capable of spanning 21 feet in
the hydrocarbon configuration and 12 feet in the sediment configuration.
The portable system can be installed in about 10 minutes and requires
almost no site preparation, the company says. Highly durable aluminum and
marine grade connections are used so the system is low maintenance and
reusable. After use during a spill, only the sorbent boom, sorbent sheets
and disposal bags need to be replaced.
The Reusable Road Spillway diverts sediment and debris commonly
encountered on forestry roads away from sensitive fish streams. The
2,500-lb rigid steel top grid deck allows all water and sediment to fall
through, diverting it to settling ponds prior to entering the watercourse.
Running strips designed to prevent grader blades from catching are also
welded to the top of the deck. Each unit comes with two pre-cast 10,000-lb
concrete abutments that can be placed easily with a 15-metric tonne
excavator. Debris can be easily removed from the spillway once the top
grid has been taken off. The deck is highly visible and the spillway is

livestock underpasses and bridges. Strong and durable, the economical
products' features include clear spans of up to eight metres, a wide range
of shapes and sizes, an ability to accommodate differential settlement and
easy handling and installation.
Twister's metal flared end sections require only standard wrenches for connection.
Attached with rods, straps or bolts, they can be completely salvaged if
pipe lengthening or relocation is required. Use of end sections reduces
entrance loss coefficients from 0.9 to 0.5, the company says. A deep skirt
anchors the end section, while preventing scouring and undercutting. Flat
bottoms eliminate twisting and misalignment of the end treatment. Stock
sizes range from 300 mm to 1200 mm, with other sizes available through
custom order. All CSP products are manufactured to CSA G401-93

Enviro-Span Technology Inc
The patented Enviro-Span archway is an inert, non-corrosive, non-metallic
and non-toxic modular crossing system that is suitable for use over fish
bearing streams. The lightweight, durable, open-bottomed arch is stronger
than steel and reusable.
It sustains the natural open channel flow with no special sub-grade
preparation or cumbersome, labour-intensive foundation elements necessary,
the company says. Logs from right-of-way clearing can be set in place as
base stringers. The modules are identical and interchangeable and their
flexibility allows them to follow significant vertical irregularities
without the need for special levelling and/or grade beams.
Modules can be produced in angled configurations to follow the natural
curve of a stream. Headwalls are also available for fill containment.
Enviro-Span arches leave the stream channel untouched with no "cast
in place" concrete, cement dust, metal, cation leaching or metal
oxides. Fish and other aquatic fauna are undisturbed.
