Underground Retention/Detention Systems

Chamber Systems provide a cost effective alternative to above ground ponds for detention, retention and infiltration applications. They collect and store the stormwater underground until the soil is able to accept it back into the ground. Puddles and saturated soil are eliminated as water is diverted into the chamber and recharged into the ground.

SWC Canada Inc. provides inspection, maintenance and repair services for underground retention/detention systems such as (but not limited to):

Stormtech Chambers
Designed primarily to be used under parking lots, roadways and heavy earth loads for commercial, turf and municipal applications.

Whitby Church ADS Underground Chamber

Cultec Chambers
Lightweight and easily transported by hand, they are ideal to install in tight areas or where minimal site disturbance is desired. Cultec Chambers may used in residential applications to control rainwater collected from gutters and/or catch basins.

ADS / HDPE Pipe Systems
Easy-handling lightweight construction, high resistance to corrosion and abrasion and the strength and durability to withstand severe loading conditions, ADS pipe is frequently used for applications in agriculture, mining, forestry, recreation and civil engineered construction projects.

CDS Water Quality Separator
Oil Grit Separators

Oil and grit separators consist of one or more chambers that remove sediment, screen debris, and separate oil from stormwater. They are particularly well suited to capture particulates and hydrocarbons from small, highly impervious areas such as residential townhouse and apartment parking lots, loading and parking areas at commercial facilities and gas stations.

SWC Canada Inc. provides inspection, maintenance and repair services for oil and grit separators such as (but not limited to):

A stormceptor is an oil grit separator/hydrodynamic separator designed to protect waterways from hazardous material spills and stormwater pollution, including suspended sediment, free oils, floatables and other pollutants that attach to particles.

The Vortechs™ system is a high-performance gross pollutant trap that effectively removes fine sediment, oil and grease and floating and sinking debris. Its swirl concentrator and flow controls work together to minimize turbulence and provide stable storage of captured pollutants.

Contech CDS Water Quality Units
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. The proper operation and maintenance of the CDS unit are essential to demonstrate your compliance with local, state and federal water pollution control requirements.

Inlet/Outlet Control Structures

SWC Canada Inc. provides inspection, maintenance and repair services for inlet/outlet control structures such as:

Catch Basins
A catch basin (a.k.a. storm drain inlet, curb inlet) is an inlet to the storm drain system that typically includes a grate or curb inlet where stormwater enters the catch basin and a sump to capture sediment, debris and associated pollutants.

Trench Drains
A trench drain (a.k.a. a channel drain, line drain, slot drain, linear drain or strip drain) is a specific type of floor drain containing a dominant trough or channel-shaped body. It is used for the rapid evacuation of surface water or for the containment of utility lines or chemical spills.

Trench Drains

A manhole (alternatively utility hole, cable chamber, maintenance hole, inspection chamber, access chamber, sewer hole, or confined space) is the top opening to an underground utility vault used to house an access point for making connections, inspection, valve adjustments or performing maintenance on underground and buried public utility and other services including water, sewers, telephone, electricity, storm drains, district heating and gas.

Head Walls
A headwall is a concrete structure installed at the outlet of a drain or culvert that functions as a retaining wall to protection against erosion, or as a means to divert flow. Precast concrete headwalls and wingwalls are a vital component of drainage culverts and bridge sections.

(LID) Low Impact Development Practices

SWC Canada Inc. provides inspection, maintenance and repair services for low impact surface intercepting water systems such as:

detaining runoff in retention ponds can reduce flooding, increase the amount of water that is absorbed into the ground, and allow pollutants to bind to sediments in the ponds or be absorbed by algae and plants instead of traveling to streams and wetlands where they may harm wildlife and human health.

Shallow ditches with gently sloping sides.

Landscape elements designed to concentrate or remove debris and pollution out of surface runoff water. They consist of a swaled drainage course with gently sloped sides (less than 6%), filled with vegetation, compost and/or riprap.

Infiltration Gallery
(a.k.a. French drain) a structure including perforated conduits in gravel to expedite transfer of water to or from a soil.

Permeable Pavers / Permeable Concrete
Also known as pervious or porous paving, permeable pavement is a type of hard surfacing that allows rainfall to percolate to an underlying reservoir base where rainfall is either infiltrated to underlying soils or removed by a subsurface drain.  Permeable pavements include:
Unit Pavers - interlocking concrete paving blocks separated by narrow gaps (pores) which are filled with sand and/or gravel
Grass Pavers - concrete cells or a strong plastic grid system with large pore spaces filled with a growing medium planted with grass or a low growing herb.
Gravel Pavers - similar to grass pavers except that the growing medium and plants are replaced with gravel.
Permeable Asphalt - consisting of an open-graded coarse aggregate, bonded together by asphalt cement, with sufficient interconnected open spaces to make it highly permeable to water.
Permeable Concrete - with little or no fine material in the mix, this concrete has a much larger than usual void space which allows water and air to move quickly through the material to the soils or the base layer below.
