These innovative systems are aimed to retain solid contaminants in Burlington to prevent floodings during storms .
These huge subway tanks also have an extremely important function: they store the first rainwater, which is the most polluting.
The works carried out by Sarens consisted on lifting and installing into place 100 pieces in 4 days.
Given the difficult weather conditions in Canada, the government of Ontario intends to carry out a stricter control over the level of water falling during storms, which will prevent occasional flooding in some important sections and areas of the city.
Storm traps are stormwater infiltration and detention systems, while jellyfishes filters are designed to hold onsite water and release lesser amounts as culverts can hold and to catch debris. These huge subway tanks also have an extremely important function: they store the first rainwater, which is the most polluting because it carries all the dirt accumulated on the streets and asphalt and regulates its flow to the treatment plants. Thus, the tanks prevent the treatment plants from exceeding their maximum flow and having to discharge the excess, untreated, into the receiving watercourses.
Sarens, world leader in heavy lifting, engineered transports and crane rental services, has participated in the upgrade of an important storm trap in Burlington, Ontario, lifting and placing each of the modules of which the storm water storage gallery consisted of.
Neil Docherty, Sarens Project Manager, points out, "The idea is that before reaching the tanks, the water passes through a series of filters to retain solid contaminants such as plastic bottles among other objects. Once in the tanks, the water is gradually conveyed to the purification stations, avoiding not only contamination of the rivers, but also preventing possible flooding and environmental damage. This is why this project is also an important milestone for the commitment to sustainability".
The works, carried out by Sarens on request of Valentine Underground Services Ltd, Southern Ontario's finest sewer and watermain contractor, consisted on lifting and installing into place 100 pieces in 4 days, with a total weight of 15,000lbs to cover 40 feet of the trench. Sarens used an AT 160 as main boom, because that was the proper crane for the most production with the least amount of mobilization.
"On this occasion, despite being a novel system, our team did not experience any operational setbacks. In fact, beyond that, we highlight the speed with which our team unloaded and placed the material, something that was of great relief to the community by not having to worry about the possible flooding that could be caused by the next storm", adds Neil Docherty.
Sarens owns extensive experience in the Canadian construction industry as well as other similar complex projects. The company was recently able to work on the renovation of Union Station, where its engineering team worked on the lifting and subsequent installation of several iron girders, weighing approximately 9.4 tons, for the flying garden that connects the station's north and south towers. In addition, other projects, such as the refurbishment of the Lafarge cement factory in Bath, have contributed to increasing annual cement production and boosted the country's construction sector, attesting to Sarens' expertise within the industry as one of the world's leading players.
