Drainage problems like blockages, leaks and scale build up can be a big issue. One, they can cause significant disruption to operations, and they can also lead to environmental damage. 

If your drains are causing issues, a CCTV drain survey performed by experts can remedy the problem. But what is a CCTV drain survey exactly? What equipment is needed? What are the benefits of having one done? And how do you know when your business needs one? All these questions will be answered in this guide.

What is a CCTV Drain Survey?

A CCTV drain survey uses specialist camera equipment to provide a live view of inside drainage systems. Engineers watch the live footage with a portable screen and identify the condition of the drain system and any related issues.

How a CCTV Drain Survey Works

A specialist camera is inserted into the drainage system to inspect the internal condition of the pipes. Video footage is transmitted in real time to a monitor above ground, where engineers assess the condition, identify faults and record their findings. A detailed report is then produced, including images, videos and recommendations for any required repairs. 

What a CCTV Drain Survey Can Detect

CCTV drain surveys can identify a wide span of issues not visible from the surface. These include blockages caused by debris or fat build up, cracked or collapsed pipes, root ingress, misaligned joints, corrosion and scale build up. Signs of wear, leaks and structural defects can also be found, and if left untreated, any of these problems can lead to more serious trouble.

What Equipment Is Used in a CCTV Drain Inspection

Generally, a CCTV drain survey will use these pieces of equipment:

  • Cameras – high resolution and waterproof
  • Push rod – flexible rods that the camera is mounted to, typically measuring 300mm in diameter
  • Remote controlled crawlers – used for larger drain systems measuring up to 3000mm in diameter
  • Recording software – to capture the footage for survey reports
  • Monitor – used by engineers to view the camera footage in real time

Why CCTV Drain Surveys Are Important for Businesses

Preventing Costly Drain Repairs and Downtime

Any type of business downtime leads to lost productivity and profit. Plus, emergency repairs often cost quite a lot, and businesses could face reputational damage due to environmental risks. CCTV drain surveys help businesses take a proactive approach by identifying issues before they escalate into major failures. 

Identifying Hidden Drain Problems Early

The majority of drainage issues below ground go unnoticed until they cause serious damage. CCTV surveys provide a clear view of the drainage system, revealing problems like cracks, root ingress, blockages or pipe misalignment. Spotting any issues early helps businesses address faults early, extend the lifespan of the drainage infrastructure, and prevent more disruptive repairs later on.

Ensuring Health, Safety and Legal Compliance

CCTV drain surveys support health and safety obligations and legal compliance by identifying issues that can lead to hazardous conditions. Faulty drains pose health risks, contaminate the environment and lead to non-compliance with local and national regulations.

With a detailed survey report, businesses will have documented evidence of the drain condition, helping to demonstrate compliance with legal and environmental requirements. 

Does Your Business Need a CCTV Drain Survey?

Signs Your Business May Need a Drain Survey

There are several immediate signs that your business needs a CCTV drain survey performed:

  • Slow drainage from sinks, toilets and service yards
  • Persistent blockages causing water to back up
  • Pest infestations due to cracked pipes
  • Foul odours and dampness near or inside your commercial building
  • Visible tree roots
  • The ground sinking or signs of subsidence

Industries That Benefit Most From CCTV Drain Surveys

Various sectors can benefit from a CCTV drain survey, especially for those where drainage issues can quickly disrupt operations or create health and safety risks. 

  • Hospitality – hotels, restaurants and pubs with commercial kitchens rely on efficient drainage to maintain hygiene standards and avoid closures caused by blockages or leaks.
  • Retail – shopping centres and supermarkets benefit from early fault detection to prevent flooding that could damage stock or impact customer experience.
  • Manufacturing and industrial – drainage systems often handle higher volumes of waste and by-products, making regular survey inspections essential.
  • Property management – CCTV drain surveys are used to monitor asset condition, resolve tenant issues and support planned maintenance programmes.

When Should a CCTV Drain Survey Be Carried Out?

A CCTV survey is not just recommended but essential for these business scenarios.

Before Buying or Leasing Commercial Property

Often termed a ‘pre-purchase drain survey’, businesses buying or leasing a commercial property should have one performed, as it reduces the risk of finding hidden issues after purchase and to ensure liability is clear in a lease agreement. Drain repairs can be expensive, and the last thing you’ll want is to be faced with unnecessary expenses when you’ve just made a significant investment. 

After Repeated Drain Blockages or Flooding

If your business is continuing to see common signs of drainage problems, from blockages and slow drainage to bad smells, flooding and pest infestation, a CCTV survey is the non-invasive way to find a permanent solution to the problem. 

As Part of Planned Drain Maintenance

Business owners and facilities managers should schedule a CCTV survey as part of their Planned Preventative Maintenance (PPM). Planning ahead will reduce the risk of disruptive and costly repairs, as well as showcase compliance for audits and insurance.

What Happens After a CCTV Drain Survey?

Every professional CCTV drain survey will result in a detailed report on findings. 

Understanding Your CCTV Drain Survey Report

The report will be digital and detail information including:

  • Diameter and length of the drain pipe/line
  • Flow direction
  • High resolution images and DVD footage of any found problems
  • Diagram drawing of the surveyed drainage system

Essentially, a CCTV drain survey report is a digital document that is information for you to make remedial action, as well as evidence for audits and insurance claims. 

Recommended Repairs and Next Steps

Your provider will also detail recommended repairs and remedial action on any faults found. Most repairs can be non-invasive like the survey itself, but more extensive issues may require full excavations.
