The Importance of a CCTV Drain Survey

By Chris Waddle


Any type of buildings should include a good drainage system. Drains allow the waste matter from the building to flow below the ground level through drain pipes. This system is great as it does not clutter the surface and also neatens the appearance of the building. It can, however, prove a difficult proposition to inspect drains lodged below ground levels. The problem should be detected and care should be taken to rectify the fault quickly. It is therefore vital for using viable solutions to tackle such problems with the least amount of effort.

It is not only during a blockage that a drain would have to be examined. There are various other times when a survey of the drainage system would have to be conducted. For instance, a person who wishes to buy a property might like to know the condition of the drain pipes. Since these are out of view and buried underground, they would not be able to readily determine the condition of the drains. They might require the services of a professional drain survey company to do the job for them. A comprehensive drain survey can locate problem areas, structural defects and bottlenecks in the drainage system well ahead of time. These would help determine the true value of the property before the purchase is made. The buyer would then be in a position to negotiate with the seller for a better price or else have them rectify the drains before the purchase.

A drain survey would also be conducted before renovations or building a new structure. Knowing the condition of the drains is crucial for most construction projects. One of the equipments used to make an unmanned drain survey is the CCTV drain survey unit. The CCTV drain survey equipment can help trained personnel inspect the drainage thoroughly and precisely. There is a wide range of equipment specifically meant for domestic, industrial and commercial buildings and drainages of different sizes and types.

The need to disrupt existing conditions is avoided with the use of the CCTV equipment. A camera is inserted into the drain through a soil pipe or manhole, during the survey. The camera is either manually guided through the drain or power is used. A CCTV monitor that is placed on ground level, records live information, which is transmitted through the camera. It is possible for the personnel trained in this field to detect any problem at particular spots that could cause a problem. This is viewed live as the camera relays a video of the actual scene. It is possible to detect any defect that may lie in any of the outlets, inlets, or running along the main pipes with this method.

The survey company can produce the entire recording in any digital format like VHS, CD or DVD for further viewing. They can also produce a drainage plan from the survey of the drain. With a thorough survey, the damage to the drain can be assessed, and the method and cost of the repairs can be estimated.
