Expert Decision-Making Relies on Quality Data

As engineers, we know the details are in the data., Whether it's manhole inspection or pipe inspection services, our goal is to provide you with accurate and reliable data that you can use to make informed decisions. Our team uses the latest tools and technologies to efficiently deliver data you can use with confidence and easily integrate with your management platforms.


Structure inspections

Our condition inspection services include structure inspections that document general conditions—deterioration, cracking, and other maintenance concerns—of your manholes, inlets, outfalls, valves, and other assets using full-manned descent, 360-degree scanners, or zoom cameras.

Smoke testing

simulates rainfall and uses high-intensity blowers to force smoke into your sewers. Clean water can enter the system anywhere that smoke escapes. To learn more, read our Smoke Testing FAQs.

Dye testing

tracks flows through your pipelines, storm sewer structures, drainage ditches, and other potential sources of groundwater inflow or infiltration. To learn more, read our Dye Testing FAQs.
