Welcome

Water and Wastewater Engineering Services

In the late 1980's, ASI earned a global reputation for our proactive response to the zebra mussel infestation of the Great Lakes . Our ever-expanding expertise in industrial bio-fouling extends to the safe control of algae, biofilm and corrosive organisms to protect clients' facilities and production. Utilizing the latest technology, our environmental engineers, scientists and technicians assure the highest degree of accuracy and performance.

Our versatile, full-service professional and technical engineering team undertakes all aspects of water and wastewater management; planning, design, analysis, turnkey operations, contract management and fabrication. Our engineering team specializes in total design/build/operate services for both industrial and municipal water and wastewater treatment projects.
Underwater Services

We own and operate a full fleet of advanced robotic vehicles to conduct civil engineering inspections, underwater mapping and remediation. ASI is the only company in the world to offer long tunnel inspections of up to 6.2 mi./10 km using ROV's without costly de-watering. In-house ROV pilots, marine geophysical and rope access technicians compliment scientific and engineering staff in open or confined water investigations and underwater mapping.
