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.

Atlantic Industries

The Dur-A-Span 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 capacity.

Polytubes Pacific Inc

The 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.

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 completely reusable.

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.
