Drones allow the inspection of sewer systems using specialized cameras and sensors, identifying blockages and damage in real time. They are safer, more efficient and cost-effective than the classical methods used, eliminating exposure to hazardous environments and collecting high-quality data enabling proactive maintenance and repair of sewage systems.

While the use of drones for the inspection of confined interior spaces, especially sewer systems, offers many advantages, there are some challenges that pilots may encounter. Here is an article that presents in a general manner this topic.

Accessibility can be a problem when inspecting confined interior spaces, because even if one does not physically descend into their premises, some doorways may be too narrow or have limited space for maneuvering the drone and implicitly its access to the canal.

Obstructions such as deposits, pipes, leaks that emit heavy steam, water seepage from the top of the channel or other obstacles can also be problematic as they can obstruct the view or progress of the drone and prevent the capture of quality images.

Drone sewer inspections can detect a wide range of issues, including clogged drains, various clogs, foreign objects or deposits, sewer system failures, cracks, and other infrastructure damage, as can also be seen in the images below.

By identifying these problems early, inspectors can take corrective action before they become more severe, preventing potential hazards and minimizing the risk of service interruption or other inconvenience.

This type of inspection offers many benefits, including increased safety, improved accuracy, and reduced inspection time and cost. By using drones, inspectors can avoid the need for human operators to enter confined spaces, reducing the risk of injury or illness. Drones can also provide more accurate and detailed images and data, improving the quality of inspections, creating a history of defects, and allowing inspectors to identify problems faster and more efficiently.

Our inspection was carried out on multiple sections that make up almost 5 km of collector channels and helped to identify several problems with the sewer infrastructure that would have been difficult or impossible to detect using traditional inspection methods.

The use of drones allowed us to capture high-resolution data, providing valuable information about the condition of the infrastructure and identifying potential problems early. By taking corrective action, we have been able to prevent more serious problems from occurring, minimizing the risk of service interruption and ensuring that the sewer infrastructure remains in good condition.

Compared to traditional inspection methods, the use of drones has allowed us to complete the inspection more efficiently and accurately, reducing maintenance time and costs while improving the quality of data collected.

Indoor drone advantages

  • Small size (diameter 40 cm)

  • Stabilization based on non-GPS systems

  • Full HD video transmission (in real time)

  • Special oblique lighting mode (embossed)

  • Visual Main Camera (RGB)

  • Secondary camera with thermal imaging (IR)

  • LEDs with a power of 10,000 lumens

  • Resistance to light collisions with objects

Advantages inspection services

  • Safer inspections, completely eliminating personnel exposure to hazardous environments

  • Faster inspections, optimal access to all hard-to-reach areas

  • Lower costs when compared to traditional inspection methods

  • High-quality data in the form of images, recordings, point clouds, etc.

  • Proactive maintenance, identifying any potential problems early

  • Minimal disruption to traffic and the environment

As technology continues to improve, we can expect drones to play an increasingly important role in inspecting confined spaces such as sewers.

If you are not yet ready to buy such a drone or want to test its capabilities first, there is the option of services for the sewer area and other industries where all the work is done by a DSP (Drone Service Provider) such as Skyline Drones (Romania), which organizes, flies and processes all the data, and the client receives only the final results.

Indoor drones are currently used in a variety of industries, such as oil and gas, agriculture, public safety, maritime, energy, infrastructure and utilities, and mining.
