Inside the pipe: advanced technologies for efficient wastewater inspection

Drainage and pipeline systems are essential to the reliable operation of homes, businesses, and infrastructure. However, because these systems are typically out of sight, issues such as cracks, blockages, or wear can go undetected until they cause significant disruption. Early identification of these problems is critical, particularly given the challenges caused by restricted access and potentially hazardous inspection environments.

Why accurate pipeline monitoring matters

Unexpected failures within pipeline systems can disrupt operations, compromise environmental safety, and lead to costly repairs. For professionals managing drainage, utilities, and industrial infrastructure, ongoing CCTV inspections are a key part of proactive maintenance, helping to identify issues before they escalate and ensuring compliance with industry standards.

Each inspection environment presents its own challenges, from confined spaces to hazardous conditions. Meeting these operational demands requires flexible, high-performance equipment tailored to the task. As Jay Neermul, Environment and RVI Market Manager at Ashtead Technology, notes: “In pipeline inspection, having the right technology is vital, not only to identify current issues but also to anticipate future risks. With increasingly complex environments and tighter regulations, adaptable, high-quality equipment isn’t just a convenience, it’s a necessity for effective asset management and operational safety”

Choosing the right inspection technology

Crawler cameras and push rod systems are two of the most widely used instruments in pipeline inspection. Each is suited to different pipe sizes and site conditions, helping execute inspections more efficiently and with greater accuracy, no matter the environment.

Crawler camera systems

In larger-diameter pipelines, such as municipal sewers or industrial drainage systems, crawler cameras are commonly used. These self-propelled units are designed to navigate long pipe runs and deliver high-resolution video, even in demanding conditions. Their stability and mobility make them particularly well-suited for identifying structural issues, root ingress, or blockages in mainlines. Systems can often be configured with different wheels, cradles, and lighting setups to adapt to a range of pipe materials and conditions.

Thanks to their precision and durability, crawler systems can be used in other challenging inspection environments, for example, assessing internal damage and wear in wind turbine blades, demonstrating the technology’s ability to deliver results in complex, confined spaces.

Push rod camera systems

For smaller-diameter pipelines or spaces with restricted access, push rod cameras provide a more compact and flexible inspection method. These systems are typically deployed in residential and commercial settings or for internal building draining surveys. Their small size and flexibility allow for detailed inspection in pipes as narrow as 25mm, making them ideal for short-run diagnostics and follow-up work.

The result: lower risk, higher confidence

As infrastructure continues to age and environmental standards become increasingly rigorous, reliable inspection technology plays a crucial role in preventing failures before they occur. By providing accurate, timely insights, advanced inspection tools help industries minimize downtime, avoid costly emergency repairs, and ensure regulatory compliance. This preventive measure not only protects assets but also supports the safety of communities and the environment.

Ashtead Technology provides a comprehensive selection of inspection solutions, from compact push rod cameras for detailed internal surveys, to durable crawler camera systems designed for demanding mainline inspections. Whether you need equipment for a short-term project or extended use, in ATEX-rated or standard configurations, Ashtead Technology has the right solution to meet your specific requirements with confidence.
