New commercial development in Moncton meets strict runoff regulations

The excavation was 3.3 metres deep that allowed for 2.13 metres of cover above the chambers.

The new McLaughlin Place retail centre found the solution to meeting the local mandate of eliminating any increase in storm water runoff while maximizing the number of parking spaces. Instead of using a detention pond or sump, the designers decided to use a system of chambers under the parking lot that would collect and hold storm water runoff from the lot and rooftops. The one hectare commercial development with five buildings will open this year and is located near the Université de Moncton. Plans call for apartment buildings to be added in the future.

Dewatering pumps help reconstruct Galveston

Storm surge attacks a seawall protecting coastal city.

When dealing with a construction site that is underwater or where the water table is just above sea level, contractors have to insure that the excavation stays dry and safe for workers. This can be extra challenging where you have conditions affected by water depth and conditions such as silt and sand. Additionally, these conditions may vary based on seasonal weather or tides. It is extremely important to have contractors who have investigated historical data and who monitor fluctuations in water levels and speeds of flow, thereby decreasing risks to workers and the success of the project.

Six critical emergency response steps

The Intergraph Planning & Response Map Module provides users the ability to place symbols for units, tactile symbols and other annotations by dragging and dropping from a list. The red circle signifies the ‘Danger Zone’ and the green areas are ‘Evacuation Areas’ for a scenario depicting a train accident in Calgary.

For many living in urban environments, mornings involve an alarm clock, a shower, a cup of coffee, and a commute of some sort – often including underground public transportation. However, while many are catching a subway on the way to work, not many understand how complex and vital their city’s underground infrastructure is to their morning routine. That is, at least, until something goes wrong.

Engineers from SNC-Lavalin found the way to meet stringent storm water drainage regulations for a portion of the new Centre Vidéotron site by designing two underground retention systems. Managing storm water runoff is a prime concern for Quebec City because the area is prone to flooding. The multipurpose, 18,000-seat arena, spread out over some 7.2 hectares (18 acres), opened in September 2015.

Precast concrete box sections specified for storm water detention structure

The detention tank is placed below the P1 level of the parking structure, to accommodate the large volume of storm water.

Precast concrete box sections were specified for an underground storm water detention tank to enable the construction of the Humber Mews Townhomes project on Evans Avenue in Toronto. The system was selected because it could reduce the total peak runoff being discharged from the site during all storm events. Using precast units would reduce construction costs and time. Other pre-manufactured solutions were considered, nevertheless, a precast system was selected as the preferred option. The structure met the service life requirements through the proven durability of precast concrete.

CDS stormwater treatment

The CDS hydrodynamic separator uses swirl concentration and continuous deflective separation to screen, separate and trap trash, debris, sediment, and hydrocarbons from stormwater runoff. CDS captures and retains 100% of floatables and neutrally buoyant debris 2.4mm or larger, effectively removes sediment, and is the only non-blocking screening technology available in a stormwater treatment device.

ADS announces addition of new Stormtech chamber

The new ADS StormTech SC-160LP Chamber is 12-inches tall with an installed volume of 15 cubic feet of water for underground infiltration and detention systems.

Advanced Drainage Systems, Inc. (ADS) has announced that it has added a low-profile, high strength chamber to its StormTech product line. The StormTech SC-160LP Chamber is 12-inches tall with an installed volume of 15 cubic feet of water for underground infiltration and detention systems. The new unit requires 14 inches of total cover to carry AASHTO HS-20 live loads, which reduces site development costs in shallow applications by minimizing the amount of needed fill and maximizing open infiltrative areas.

Riverside community uses fusible PVC pipe for stormwater outfall

At Keswick on the River, a community in southwest Edmonton, a new 100-year flood protection system conveys the stormwater through an underground trenchless system using Fusible Brute PVC pipe from IPEX.

Established in 2010 through the adoption of the Keswick Neighbourhood Structure Plan (NSP), Keswick on the River is a new community in southwest Edmonton, Alberta. Bounded by the North Saskatchewan River to the west and the Windermere Golf and Country Club to the north, the 200-acre neighbourhood is named for a quaint town in northwest England and features more than 1,500 homes that offer old world English architecture designed to look and feel like a country village. Future residents of Keswick on the River will enjoy riverside living, playgrounds, a nature trail system and easy access to Edmonton.

Storm drain system succeeds in salt marsh for mega-mall complex

A 6-metre-long section of large diameter SaniTite HP pipe is moved into place. The polypropylene pipe provides the additional stiffness plus the long bell and dual gaskets needed to compensate for the area’s soft soils.

In early 2014, the Tsawwassen First Nation started construction of two mega-malls. To accommodate stormwater runoff from this 73-hectare project, a large-diameter pipeline was designed and installed under the public roads surrounding the sites. The selection of the pipe needed to take into consideration corrosion resistance, due to the salt water environment, and had to offer structural strength because of the poor deltaic soil conditions in this seismically active region of British Columbia.
