Egmond Associate Ltd (EAL) is a consulting company that offers a wide range of engineering services. With almost 25 years of industry experience, we specialize in Environmental, Geotechnical, Hydrogeological, and Hydrological Assessments. We provide geotechnical, environmental, storm water, hydrogeological, materials and forensics consulting and testing services.
Our services are designed to help you be "Safe by Choice and Measure™". We want to help you identify and manage your risks so that you can take proactive measures to mitigate the risks before they become problems.
We have completed thousands of investigations across Canada and the United States. EAL has completed projects in Ontario, Quebec, British Columbia, Saskatchewan, Manitoba, the Northwest Territories, Nunavut, Minnesota, and California. Our clients range from governments to individuals to industrial and commercial clients.
EAL carries out Geotechnical Investigations to determine the stability of structures, slopes, etc. The Geotechnical Investigation is designed to ensure that the soil can adequately support a proposed structure. EAL’s geotechnical investigations include analysis for footings, soil strength, slope stability, permafrost, dewatering, building cracks, settlement of walls, slab settlement, water tables, and anchors.
We have carried out investigations on a wide variety of projects including towers, dams, hospitals, tunnels, roads, residential developments, individual houses, and other infrastructure.
Egmond Associates Ltd offers clients the ability to explore for tanks, buried pipe lines, buried structures, and contaminant plumes.
Using EM 31 or 61 or Megger technologies we can take contact or non contact reading of site conductivity. Conductivity plots can be used to develop plans of site showing anomalies commonly associated with tanks, lines, wells, structures, and the like.
With our Megger we can carry out grounding and resistance studies for grounded sites. We can use the Wenner Method to investigate resistivity and corrosion potential.

Egmond Associates Ltd (EAL) offers structural engineers on site testing for shear wave velocity for the upper 30m of soil and rock.
Using the ReMI method we develop the building code Class estimates in the upper 30m (100feet). Using only background seismic noise, or generated seismic noise for very quiet sites, the ReMi method allows us to estimate shear and compression wave velocities. From these velocities we can generate first estimates of soil bearing capacity.
Estimate bearing capacity.
Refracted Microseismic events are used to generate shear wave profiles of sites(see figure below)
Trace subsurface horizons (see figure below)

SAGES™ is an innovative water conservation technology that successfully converts storm water into groundwater by utilizing the existing infrastructure to disperse storm water underground into the vadose zone.
SAGES™ is installed into the bottom of an existing culvert or a catch basin. Instead of redirecting the water down a series of storm sewers and emptying into a river, SAGES™ filters the water and disperses it into the ground above the local aquifer. The water is filtered through layers of crushed gravel, pea gravel, sand, and activated carbon to remove sediment and particles from the water. This filtering process is designed to imitate the natural soil filtering process that took place prior to urban development.
The unit consists of a pipe and a cartridge filter, which is placed inside the pipe. The filter removes suspended material and polishes the water before it is released into the ground.
SAGES™ is installed by drilling a conventional well hole in the bottom of a new or existing culvert or catch basin. The SAGES™ system is lowered into the hole and the filter sits in the pipe just above the water table. SAGES’™ ability to utilize existing storm water infrastructure minimizes the costs of upgrades by allowing the existing infrastructure to be rehabilitated at a much lower cost and shorter time frame than conventional upgrades.
Any overflow from SAGES™ is handled by conventional storm systems.
Furthermore, maintenance is simple. As part of a regular catch basin maintenance program, the filters are removed periodically, cleaned, and reinstalled. The removal of the filters is a simple procedure that can be completed by your maintenance staff.
Every year, governments around the world devote spend millions of dollars to ensure that there is an adequate supply of drinking water to meet the needs of their ever growing populations. Cities are increasingly reliant upon costly imported or diverted water as local aquifers slowly diminish.
The increasing urbanization of cities with their impervious asphalt surfaces has resulted in the inability of rain water to infiltrate the soil. Rain water is washed away into rivers and streams where it flows downriver and provides little or no benefit to the local community. This eliminates the primary source of water for aquifers. Consequently, local aquifers are unable to regenerate and replenish themselves. This has caused chronic water shortages in cities across North America.
SAGES™ offers an easy, cost effective solution to this ever growing problem. The approach is simple: SAGES™ redirects water that would otherwise have been washed away down storm drains with little or no benefit to the local community into the local water supply. SAGES™ aides in the regeneration of aquifers by putting the storm water into the ground in the vadose zone directly above the aquifer.
Consequently, SAGES™ allows for the harvest of previously unused waters in large quantities for a fraction of the cost of alternative water sources. SAGES™ reduces the long term cost of water by tapping into a new, previously undeveloped, local source of water. This new water source is cheaper than alternatives such as desalinating ocean water, importing water from long distances, filtering sewage water, and other methods. By redirecting the water from storm drains into the local aquifer, EAL is able to provide an additional, low cost, source of water than can provide water to hundreds of thousands of residents in a major metropolitan centre.
Storm Water Management
SAGES™ is a cost effective means of upgrading the capacity of municipal infrastructure to deal with storm water. Rather than embarking on the costly process of replacing existing storm water pipes with larger pipes, SAGES™ allows you to increase your capacity to handle storm water by simply installing a SAGES™ unit into your existing infrastructure. SAGES™ is simple to install and redirects a portion of the rainfall into the ground where it replenishes the local aquifer instead of emptying it in to a river or a stream to wash away and provide no benefit to the local community. SAGES™ thereby simultaneously solves two chronic problems facing municipal governments across North America. Furthermore, SAGES™ reduces storm water flows helps protect lives, property, downstream habitats, and recreational facilities from elevated water levels created by storm runoff, reduces flooding and erosion, and has a smaller footprint than traditional storm water ponds.
Egmond Associates Ltd offer services related to storm water. Our team work in the fields of water resources engineering and watershed planning, ecosystem restoration and conservation, sustainable site design/planning including LEED™. Our Services include:
Egmond Associates Ltd offer services related to the management of watersheds and hydrosheds.
Watershed – Watersheds represent those areas which are above the surface and ultimately drain to a single discharge point. The edges of a watershed are defined by the highest elevations of continuously connected ground draining toward a single outlet. One watershed can be a sub-watershed of a larger watershed.
Hydroshed – A hydroshed represents those volumes of the earth, below and on the surface, that interact and form a continuous bounded interacting systems of water flows.
Aquifer Storage And Recovery – Is the deliberate manage of inputs and outputs from a hydroshed using surface water and groundwater interactions.
The management of watersheds and hydrosheds using controls, monitoring, inputs, extractions, natural systems, in order to optimize life and performance is one offered service. Whether this is for simply measuring rainfalls or designing systems, our team can assist you.
