History and Growth

ASI Group Ltd. (ASI) was founded in 1987 as Aquatic Sciences Inc. by a small team of industry professionals committed to providing integrated engineering, ecological and marine services to clients worldwide.

In the late 1980’s, ASI gained a global reputation for our proactive response to the zebra mussel infestation of the Great Lakes. Our company has the distinction of being the first to perform a chlorination treatment for zebra mussels in North America.

To complement the successful zebra mussel program, remotely operated vehicles (ROVs) were introduced to ASI’s list of services during the early 1990’s. This allowed for the team to inspect underwater areas that a diver simply could not access due to safety, space or depth issues.

We are a full-service engineering and technology based company with a focus on all aspects of underwater infrastructure inspections, maintenance, repair and the design, build and operation of water and wastewater treatment facilities.

Presently, the ASI team consists of over 100 experts including Professional Engineers; Certified Engineering Technologists; Environmental and Engineering Technicians; Water Quality Analysts; Licensed Commercial Divers; and Underwater Inspection; Surveyors and Hydrography specialists.
