Watercare Asset CCTV Pre and Post Inspections

Working on a property development or construction project sometimes entails installation, modification and extension of public drainage systems. As a result, you may be required to apply for a Works Over approval.  Typically, before proceeding with the project an engineer or Watercare representative will get involved to ensure compliance is met and to ensure that the process won’t put the Watercare assets at risk of getting damaged.  

As a drainlayer, we help you ensure that the condition of any public sewer system is investigated before or after any work takes place. The inspection procedure is carried out with CCTV equipment and still images.

Watercare Asset CCTV Inspection

Before Watercare Asset CCTV Pre and Post Inspections became popular, plumbers had to do open-cut excavations. While sewer excavations can deliver results, it can be a very intrusive process. It also consumes a lot of time and costs a lot of money. Unless you are 100 percent sure that the pipe damage is severe, you don’t need to opt for a sewer excavation service. 

A CCTV drainage survey is more than enough to help you find the root cause of your drain pipe problems in a residential or commercial property. It’s also the fastest, most practical and cost-effective way to inspect Watercare assets. 

How does CCTV Pipes Inspection work?

The process involves inserting a sophisticated camera to inspect the pipes. For larger pipes, like those used in sewerage systems, a CCTV tractor is used. For smaller ones, such as those used in Watercare assets, plumbers utilise a snake profile camera. 

As the plumber pushes in the camera inside the pipes, you get to check for possible problems such as clogs, cracks and leaks. You can either have the option to check the video feed in real-time or review it after the service with the DVD provided by the plumbing company. 

Typically, the video contains overlaid text containing details like the pipe name, street address, pipe diameter, pipe shape, date and time of CCTV inspection and depth of the access points. 

After the survey is done, the plumber will discuss the findings. Below are some of the key things that you can check via a CCTV pipe inspection:

  • Hairline cracks that affect the integrity and stability of the pipes
  • Bigger cracks that can affect water pressure and bring in sand and silt inside the pipes
  • Tree roots and other organic debris stuck inside the pipes
  • Punctures on the pipe due to previous renovation work
  • Corroded or severely damaged pipes and assembly joints
  • Location of other pipe joints and how to access them
  • Pests such as cockroaches and rats that poses risk for pipe damage and health issues

Timely or regular inspection of drain pipes through CCTV surveying can help you save a lot of money on repairs or other services. It can also help you find out what plumbing issues you need to address before proceeding with a construction, development, or renovation project. If in case the sewerage pipes in the property need work because of material buildup, you can avail a combo package which includes CCTV pre and post-inspection service and drain unblocking.

Beyond Pipe Repairs and Damage Mitigation

Besides coming handy in finding plumbing issues to fix in a property you already own, a CCTV drain survey can also be useful in other scenarios. For example, before you purchase a new property, you can have the pipes inspected to check for pipe problems. 

It will help you determine whether it makes sense to invest money in a certain property. Knowing potential or existing drain pipe issues would also allow you to renegotiate the price so you can make room for your renovation expenses.

A typical CCTV survey would only cost you hundreds of dollars per hour. It’s a good investment whether you’re a property owner or a property developer.  

The Drain Pipes are Damaged or Clogged, What’s Next?

If the CCTV survey indeed reveals that your pipes are damaged or clogged, your next priority is to plan your next step. You can figure out the approach to use, depending on the severity of the problem. For example, if the results show hairline cracks, you might need to have the pipes repaired to prevent further damage. If the pipe problem arises from material build-up then the plumber can use a different approach like hydro blasting.

What To Do If Your Drains Are Not Draining

Are your drains slacking on the job? Maybe you’ve noticed that your drains are not draining as quickly as they used to, or maybe they are even flooding! If that is the case, you most likely have a blocked drain, and this is not as uncommon as you may think.

Why do drains block?
Common caused for drains getting blocked include:

  • Rubbish stuck in pipe
  • Leaves or other substances blocking the pipe
  • Damage or collapsed pipe
  • Tree roots which have grown into the pipe and blocked it
  • Silt and dirt build up after years of drainage service

Blocked drains are actually a common problem and can cause serious issues if left untreated. Blocked drains can cause health issues and property damage. If you have noticed a blocked drain, you would be wise to act on it.

What to do if you notice a blocked drain
If you notice a blocked drain, you should pick up the phone and call a drain unblocker. The best and fastest way to see what is causing the blockage is by means of a CCTV drain inspection. The drain unblocker will put a CCTV camera down the drain to see what is causing the blockage, and once this is known then appropriate action can be decided.

Here is an example of a CCTV drain inspection:

Once the blockage has been identified, it can now be decided how to best tackle the problem. The solution will depend on whether it’s a blockage or whether the drain is damaged.

If the problem is a blockage, the most likely course of action wiull be to unblock it by means of Hydro jetting. This involves putting a jetting hose down the drain, which sprays water through a water jet at very high pressure to clear any blockages. This method is faster and cheaper than all other drain unblocking solutions, and can be used on all sizes of drain pipes.

If the drain has been damaged, whether it’s by tree roots, burst pipe or otherwise, the solution will involve repairing the broken section of pipe. This is more complicated than a drain unblocking but is necessary to get sorted.

Drain Unblocking and CCTV Inspection

Blocked drains can be a huge pain. Aside from the unpleasant smell and mess caused by the water backflow, you also have to deal with repair costs and the potential health hazards that may arise from it. While small blockage can be resolved using a drain snake or other home remedies, water backflow, leaks home remedies, chances are your drains, stormwater pipes or sewers need to be looked at by a professional.

At Drainage NZ, we have a team of master plumbers and repair engineers as well as modern equipment required for any drain-related jobs, including drain unblocking and CCTV inspection.

Drain clearance involves a two-step approach. First, we’ll carry out an inspection to identify what’s causing the blockage and where it is located. Then, we’ll prescribe the best technique to clear out your pipes.

Causes of Blockage

Blockage rarely happens since modern pipes and sewers are now manufactured to demanding standards. And if your pipes were installed by skilled drainlayers, the chances are even slimmer.

However, blockage does occur due to the following reasons:

  • Accumulated leaves and debris from trees
  • Tree roots that grow into the pipes through a crack of failed joint due to ground settlement
  • Badly aligned or broken pipes (usually there’s a lip obstruction where materials in the sewage flow get caught)
  • Tissue, sanitary pads and other products that are flushed in the toilet
  • Foreign objects that were forced down the drain
  • Accumulated food scraps and cooking grease

If water drains at a slower rate than normal or the toilet bowl fills to a higher level than usual after being flushed, chances are there’s already partial blockage. It’s best to call an engineer at this point to avoid a bigger headache later.

CCTV Inspection + Drain Clearance

To work out where the problem lies, first we check the disconnector trap (DT), the ground floor toilet bowl, the interceptor traps and the sewer pipes for any signs of blockage.

If the problem cannot be determined  by this process of elimination, we will conduct a CCTV drain survey. Using this technology ensures a speedy analysis, accurate diagnosis and minimal disruption as we no longer have to carry out a large excavation to locate the blockage. This also means less inconvenience and costs on your part.

We’ll locate a suitable entry point for the CCTV camera, inspect the condition of your underground pipes and determine the best way to go forward.

In some cases, we find that blockages are caused by the public drain/sewer failure and the liability is not yours. In such situations, we will advise you to ask your water company or the local authorities for recompense.

At Drainage NZ, we use waterjetting or hydro blasting to clear away debris, thaw frozen drains or break up fat deposits. If the blockage can’t be resolved this way, an excavation will be required to ensure the blockage is thoroughly cleared and won’t happen occur again in the future.

When Was The Last Time You Had Your Drains Inspected?

Drainage systems can go for years without issues. But they can also slowly build up issues and one day, without sign, they go pop! This can be very hard to predict, and can hit you with a nice, substantial bill when it happens.

What can you do to ensure that there isn’t a problem building up in your drainage system?

CCTV_drainage_inspectionsGetting your drains regularly inspected with CCTV will tell you what condition your pipes are in, if there is any damage or any blockage building up. You will also see if the pipes are starting to break down. This will give you a clear indication of what’s going on in there, and anything you should be wary of. Always remember that it is cheaper and less stressful to pick up a problem before it happens!

CCTV inspection is also necessary if you have a leak or blockage before any work is done because it tells you what the issue is and how to tackle it.

We at Drainage NZ can help you to inspect your drains whether you just want to make sure all is ok or you have a problem. Speak to us today!

Why You Should Always CCTV Your Drains After Unblocking

It is common knowledge that if your drain is blocked, the first thing to do is to do a CCTV inspection to see what is causing the blockage, so that you then know how to deal with the problem. However, did you know that it is also good practice to do a CCTV inspection after the drain has been unblocked?

Why_CCTV_after_unblocking_a_drainWhen completing any work of any kind, it’s always a good idea to check it over and make sure it has been done right. This will ensure that there are no surprises later on or that you missed something that should have been fixed while you were there. That goes for drain unblocking as well. By checking the drain after you have unblocked it, you will ensure that the blockage is fully clear, there isn’t another blockage further down and there is no damage to the drainage pipe.
