Earlier condition awareness
See visible conditions and access constraints before committing people and equipment.
Sewer inspection drone
Inspect sewers and culverts without making entry the first step.
COAX is a compact inspection drone for close-range data capture in underground drainage infrastructure where access is constrained and GPS is unavailable.
Plan a pilotCOAX + RevSight
A closer view of underground infrastructure
Sewers, culverts and larger collectors can contain standing water, deposits, obstructions, damaged surfaces and uncertain access conditions. COAX is intended to gather visual evidence before teams plan cleaning, repair or closer specialist examination.
Sewer inspection drone
What remote sewer inspection can improve
Low-light data capture
Gather close-range imagery in dark underground infrastructure where GPS is unavailable.
Traceable findings
Organize observations and source evidence in RevSight for maintenance planning.
Use cases
Potential sewer and drainage use cases
Flight suitability depends on diameter, airflow, water level, obstructions and communication conditions.
- Large-diameter sewers and collectors
- Stormwater culverts and channels
- Access chambers and connecting structures
- Initial assessment after blockage or incident
COAX + RevSight
Prepare the inspection around site conditions
A useful pilot combines route planning with a clear list of observations to capture.
Survey access
Review entry points, dimensions, water, airflow, obstacles and communication range.
Capture evidence
Fly the agreed section and record visible defects, deposits and obstructions.
Structure findings
Connect observations with footage and prepare an actionable inspection record.
FAQ
Sewer drone inspection FAQ
Can COAX fly underground without GPS?
Yes. COAX is designed for GNSS-denied environments, including underground and enclosed infrastructure.
Can every sewer be inspected by drone?
No. Suitability depends on available space, water, airflow, contamination, obstacles, access and communications. These conditions must be assessed first.
What defects can visual data help identify?
Depending on visibility, imagery may reveal deposits, obstructions, surface damage, displaced elements, infiltration signs or areas requiring closer specialist testing.
