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.
GPS surveys
capture Geographic Information System (GIS) details of each of your assets to map and advance asset management and hydraulic modeling programs. RJN is a Silver-Tier ESRI Business Partner.
Private property inspections
identify drain or sump pump connections to your sewer system contributing to inflow and infiltration (I/I). To learn more, read our Building Inspection FAQs.
Internal pipe inspections
pinpoint the location of I/I sources or leaks. Our complete toolbox of in-pipe inspection technologies including our Rapid Inspection Technology (RIT) can drive your planning and preventative maintenance programming.
