Drain Survey Southend on Sea
What are the main uses for a CCTV survey?
A CCTV survey can reveal problems in your drainage system which you may not have known about before e.g. cracks, blockages, roots, etc. This information could then help you in deciding if you actually need any work done on that particular drainage system in order to fix the problem, or if it would be better to replace that section completely. If left untreated these kinds of problems with your drains could lead to further complications e.g.: flooding, subsidence, or even risk of damage to your property.
What is a CCTV Drainage Survey?
A CCTV drainage survey, or a drain survey as it's often called, is a process that enables the inspection and recording of any physical condition found in pipes. This can be done by using a small camera that is sent down into the pipe to shoot pictures of the insides as well as collect data regarding dimensions, alignment, and even traffic flow. The latter will point out obstructions such as tree roots or misaligned joints.
Why have a Drain Survey?
After performing several different kinds of drainage survey work for our clients, we've noticed that many people from all kinds of backgrounds ask themselves this same question before hiring us. The answer varies depending on what type of facility needs a drain survey and what the reason is behind it. We complete drain surveys around Southend on Sea, and Essex, for residential and commercial clients.
CCTV drain inspection is carried out in order to check the inside of drains, sewers, and culverts on land for defects including cracks, roots, blockages, etc before expensive repair work is done which could be more extensive than originally thought. Once any suspected damage has been seen it can then be reported back to you with an idea of what the problem might be and how much it would cost to fix.
This information can help homeowners make informed decisions about their next course of action such as whether full replacement instead of repair work would be more beneficial. It can also avoid unnecessary excavation if there are no major problems present; this will save time and money.
Some other reasons for drainage surveys
To know before work begins how long a project will take. An excavation, for example, can be much more time consuming if there are obstructions in the pipe. It's one of the first things that need to be checked out when planning new building projects or renovations.
If you have an existing facility and want to expand it by adding new piping, you'll probably want to know where the old pipes are located before starting construction on new ones. Once again, having an obstruction would make this process drastically different from constructing a brand new system without any concern of what lies beneath the surface. It could cost you a lot of time and money.
Anytime that you are planning to dig up the ground near old piping, it's important that you know how deep they are before selecting new locations for your pipes. This is especially true when installing underground utilities--water lines, electrical cables, gas lines, etc. If you bury something too shallow or too deep, there can be safety concerns or damage to the line itself.
If your primary concern is safety, it may not always be necessary to get an exact layout of all existing piping beneath the surface in order to ensure safe operating conditions. But again, knowing how far beneath the earth they're buried will help in this process. Knowing where the deepest points might be (or if there are any) can help you avoid digging too deeply or horizontally.
If your primary concern is accuracy, then you will need to know both the exact location and depth of any lines that are already in the ground before placing any new ones. If there are no existing lines where you're planning on digging, then knowing exactly how deep to dig (and how many feet it should take you) is crucial for safety as well as avoiding disruptions in future service or damage to existing equipment.
A CCTV drain inspection can help determine the integrity of your underground system by visualising existing pipelines. Old, damaged, incorrectly installed piping costs people time and money every day. Most commonly damage comes from physical impact or water seepage that is able to corrode steel piping over time. Physical damage most often occurs at pipe joints, valves, wall openings, ground-level crossings, etc... Water enters sewer systems through cracks in the line itself, broken joints/connections with other pipes, floor drains if they are connected to sanitary sewer lines directly or plugged sumps (if there is any line leakage).
To inspect these areas you need special equipment, and it is most commonly a "camera" or the so-called "CCTV drain survey". The main purposes of such surveys are: to detect any defects along the drain - internal and external corrosion, cracks in concrete sewers, reduction in cross-sectional area of steel piping due to corrosion, etc. Some defects can be discovered by traditional methods with metal detectors and when using a smoke test with compressed air. However, that is not always reliable (due to obstacles like a large number of roots in sewer drains for example).
CCTV Drainage Survey for Insurance Claims
If you are planning to sell your house: You should definitely get a CCTV inspection done before putting it up for sale. Detecting problems early enough may save you from future expensive repairs and the bad reputation of your property in the neighbourhood. Another important aspect is that having a video record of sewer line conditions could be crucial evidence when the time comes to put up a claim against a warranty or insurance company.
The best reason for it is if you already suspect something wrong with your sewer lines, wish to avoid unpleasant surprises in near future, or if somebody else is paying for it. Most people think that getting a drain survey done will actually help them reduce the cost of avoiding damage to their sewer lines, but this might not necessarily be true. Most insurance companies do not pay for any repairs done without having valid proof like CCTV records to back their claims. Also, if you are planning to sell your property it's always good to let the potential buyers know about problems with sewer lines before they move in; this gives them enough time to make alternate arrangements and reduces chances of future legal conflicts over damages caused by faulty sewer pipes.
FAQ About Drain Surveys
Many people ask what exactly goes into conducting a drain survey, so here are some standard questions that we receive regularly with their answers:
Q: How long does it take to carry out a drainage survey?
A: Usually one day but can be spread over a few days if your system is very large.
Q: What maintenance should I expect after a drain survey?
A: We will provide you with a free maintenance schedule designed specifically for your system, this includes recommendations on how often each area should be cleaned and what cleaning products should be used.
Q: How much does a drain survey cost?
A: The cost of drain surveys varies depending on how deep into the drain system the camera has to go and what other problems might be found. It may be cheaper for you than meeting the costs of excavating up to the manhole to take a look. Also taken into account are the size of the drainage system in question, how complex and the length of the drainage system. Fees are charged per 100m of sewer or surface water drains/pipework that requires to be surveyed from the manhole cover located at our access point. We also charge extra for carrying out work inside manholes i.e., jetting, CCTV surveys, etc.
Q: Who is qualified to carry out a drain survey?
A: Our technicians are all fully qualified, experienced and employ the latest technology available to ensure your system is surveyed correctly. They hold NDT level 3 certificates for assessing defects in concrete construction of pipelines as required by current UK standards BS EN 1433-3, they are also quality assured to work on potable water systems within drinking water treatment plants under BS 8666.
What does a CCTV drainage survey show?
A CCTV drain survey will be performed by a drain inspector who will use the camera facility on the van to inspect your drains from manhole or inspection chambers located in your road/pavement/driveway - usually near the footpath gully trap. They will look for problems such as blockages, root invasion, and defects within the pipe itself, also noting any obvious damage to the visual elements of the infrastructure e.g. damage to brickwork, cracks in asphalt or paving slabs, etc. The location of any defects they find is logged so this can be used as evidence if needed later on. If a sewer is having problems the inspector may run the camera down into it from more than one manhole to find its endpoint and determine whether water infiltration is coming from another source e.g. from a roof or a leaking side drain.
A video report of your drains will be made which you can view at the van on a laptop, tablet, or smartphone if they have an internet connection available - usually they do not as this will require downloading large amounts of data quickly, and often there isn't time for this before their next job. You can also opt to take away a USB drive with all these files that would include any pictures etc that were taken along with notes about what was seen in each shot, how deep it was etc.
The notes are pretty comprehensive having been written up by an experienced operative using his own words, or very close to it. They are not transcripts though so don't expect him to say every little thing that's recorded in the camera shots. If you would like something done differently then please let your contractor know.
You will be asked if you want the pipe mapped on the video report - this means that they draw over all of the images (which can mean there is some duplication) and show where each one was taken along with what's seen on screen. This makes it much easier to understand especially for anyone who isn't used to reading CCTV drainage reports!
If there is something that needs additional clarification from the operative, they will do their best to get this clarified for you and add it to the notes section. For instance, often they may not be able to tell what's causing a problem without some further investigation (especially if it was installed by another company). If this is the case then they will highlight this in their opinion.
