We have a maintenance free, environmentally friendly solution that pays for it's self. It keeps the eager beaver from plugging the culverts and damaging roads and railroad grades from flooding.  This saves your business or agency thousands of dollars per year in repair and maintenance costs.

We now also have BPAO's available in plastic!!

 It can be adapted to fit 

They can be made to fit any shape of drain up to 1200mm. Round, square, and even one that is out of round!!
500mm, 600mm, 800mm, 900mm and 1000mm have already been installed in several areas of Northern Alberta by major oil companies, some county's and forestry services. 

These pics were provided to us after the install of our new plastic BPAO's by a Major oil company in Northern Alberta.

These new ends are light weight, provide increased flow, are corrosion proof. This makes them ideal for brackish and salt water applications.

The pictures shown here have a 1200mm BPAO feeding a 1000mm culvert.

The BPAO can be utilized in road systems and railroads to stop the flooding and washing out of the grade, it can also be used in reservoirs and dams to control the water levels. 

This BPAO can be used on existing culverts as well as with new culvert installation. By using this BPAO with new grade construction, you have eliminated the problem before it has started.

The BPAO is an environmentally friendly and humane way to control all your beaver problems; plugged culverts, flooded roads, and problem beavers.

Hundreds of these BPAO's have been installed and proven over the last several years. These BPAO's have been operating maintenance free since being installed. 

The only problems we have encountered, was when they were not properly installed.                               

When doing the installation, ensure the culvert or culverts are large enough to handle the flow. When properly installed there is no need for steamers in the spring to open the culvert. 

The BPAO can be manufactured to fit culverts that are sloped such as the ones that are installed in highways and most M.D. roads. 

When the BPAO is used in reservoirs or dams the water level can be maintained by installing a control gate on the outlet end.

The BPAO is permanent, with proper installation it will provide you with years of continuous protection from nature's most engineering creature THE BEAVER.

NO STREAM SILTATION AFTER INSTALLATION !!!

Check out the largest BPAO we have made yet!  It is installed on an 1800 mm culvert by Weyerhaeuser in Saskatchewan. 

This year we made an even larger BPAO, it was going onto a 2400 mm culvert!!  If you have a culvert, we can design a BPAO to fit.

Have a look in the photo gallery for more installations.  Also check out our new installation pictures.
