Are Blocked Drains a Mammoth Task? Not With a CCTV Drain Survey

Recently workers digging up a drain near Mexico City discovered the fossilised remains of a mammoth. These dated from around 14,000 years ago. In terms of blocked drains, a mammoth would be quite an obstacle. You might think it unlikely that drains might contain large blockages without it being obvious, but in fact drains can accumulate large amounts of debris and waste over time. This is why the contemporary technological solution of a CCTV drain survey can prove invaluable.


The Tip of the Fatberg

Fatbergs are lumps of congealed fat and household waste, which accumulate in the sewer system. In 2015 a lump 40 metres long was discovered in a sewer in London. Essentially consisting of compressed wet wipes and cooking fat, the fatberg was so big it had broken the sewer.

This is an extreme example, but household waste gathers into smaller fatbergs all the time in drainage systems. Fat can coat the inside of drainage pipes, reducing their normal diameter, and therefore their efficiency.

This kind of disruption to normal drainage systems can occur over time, with a gradual build-up of blockages. However, the warning signs can appear early on, if drainage begins to seem less efficient.


The Benefits of Advance Knowledge

Having a CCTV drain survey gives you certain key benefits:

  • it enables you to find out in advance of commissioning any work, exactly what issue there are with your drains
  • it provides you with clear, documentary evidence, and can indicate the right course of action to take next; and
  • it’s very cost-effective, both in terms of manpower and potential disruption.


The process of a CCTV drain survey involves us sending cameras into your drainage system to record the condition of your drains. This is both evidence-gathering and diagnostic, providing us with vital information about the following:

  • the precise locations of where your drains run;
  • the size of the pipework;
  • the condition of the internal pipework of your drains;
  • any otherwise hidden connections; and
  • any defects to the pipework.


Once we have the results, we can compile a full report about the state of your drains, the CCTV footage on a DVD, and a recommended course of action to remedy any problems or defects.

We can give you peace of mind by providing you with the right kind of information about your drains, and we can detect problem areas before they cause significant disruption to you.

Whether you’re a household, a business or other organisation, having a proper functioning drainage system is vital to your day-to-day life. Contact Drainage Consultants today to find out more about how a CCTV drain survey can help you.
