A road in Waverton, Chester has had to be closed because of a sewer collapse.

Residents noticed there was a problem when the tarmac on the road began to sink leaving a crater in the road. The road in question, Moor Lane, was visited by the highways department who decided to close the road and put a diversion in place. The closure has caused problems for the local post office. Sharon Senior who owns the post office stated:

“We couldn’t believe it. On the Friday when the road was closed it was just dead, and it has been dead all week. We are really struggling now because people aren’t driving past and are just going elsewhere.

“Our business usually drops during the holidays, but this year it had been quite steady, but this is crippling us.”

The local council contacted a drain inspection engineer from United Utilities who was called to the site and quickly determined that a collapsed sewer was the cause of the problem.

A United Utilities spokesperson stated:

“We have established that work will need to be undertaken at two points on the road, one outside the post office and another further down the road. The work is expected to be completed in two weeks. We do obviously sympathise with the owners of the post office. We will do our upmost to get the work done as quickly as possible. It is expected to last two weeks.”

One of the most common causes of drain blockages is root intrusion.

The roots from trees and plants in your garden often find their way into the drainage pipe that leads from your home to the public sewer in their quest for an easy source of water. And because some of the drainage pipes that lead from homes are in excess of 50 years old, their structural integrity is not as it once was. This leads to the connection points between the pipes breaking down and roots getting into the system.

Once in your drainage system, roots will quickly multiply until the root ball created completely blocks your pipe. At this point the waste water that needs to be taken away from your home will no longer be able to flow though the pipe and it will overflow. In some cases this overflow may be into your home and can cause serious damage for the homeowner.

If you have a drain blockage caused by root intrusion, a drainage contractor will use a spinning root cutter to remove the roots from the pipe. They will then use CCTV survey equipment to look at the damage caused and suggest a remedy such as a patch liner repair to solve the problem.

A road in Evesham has remained closed all week after the sewer underneath the road collapsed in three places.

Emergency work was started last week on the sewer in School Road after sewage made its way onto the public highway. Because of which, Severn Trent water drain inspection engineers hastily arranged a meeting with the local council to close the road when it because apparent it was not going to be a quick fix.

A letter was sent to local residents explaining the problem. In the letter the senior operations manager from Severn Trent stated:

“These things are not acceptable, are unpleasant for customers who live nearby and we need to deal with them on an emergency basis.

“We understand that School Road is an important route between parts of Salford Priors village/Irons Cross and Bidford/A46.

“That’s why we are doing the work with a road closure so we can carry it out and complete it as quickly as possible.

“We realise that emergency work such as this can be disruptive but we will do all we can to keep the impact of our works to a minimum while we restore Salford Priors sewage pipe network to full operation”.

The road is expected to reopen this Friday.

Most of us have had to deal with a blocked sink or toilet at some time in our lives. Most of the time the blockage can be removed easily and the waste water can flow freely again. However, on the occasion that the drain cannot be unblocked, what can you do?

If you have attempted to unblock your sink or your toilet and you are still experiencing problems, you may have a larger problem than first anticipated. The best thing to do here is call a drain inspection engineer to assess the problem.

A drainage contractor will have all the necessary tools to unblock the drain and hence you will not have to put your health at risk by coming into contact with ‘dirty’ water.

Drains and sinks can become blocked for a number of reasons, but it’s usually something that’s not biodegradable that has found its way into the drainage system that is the cause of the problem.

Common items likely to block a drain include:

  • Food waste
  • Cooking oils and fats
  • Sanitary wear
  • Nappies

A drainage contractor may use a high pressure jet of water down the drain to remove the blockage, or may suggest a CCTV survey to find the root cause of the problem. No matter the drainage problem they will be able to help.

Motorists are being warned to find an alternative route or expect severe delays on the A34 Queensville in Stafford after a sewer collapsed.

The sewer, which runs under the road surface, had been expected to be repaired quickly, but the discovery of a gas main in the same trench has meant work needed to be halted until the area was confirmed safe by National Grid Gas.

Drain inspection engineers are continuing to assess the best method to repair the drain safely, whilst temporary traffic lights are put in place. A spokesperson for Severn Trent Water stated:

“We’ve not been able to progress further with the sewer pipe repair as we’re still assessing how best to tackle what’s needed.

“The excavated trench contains gas and water pipes as well the damaged sewer pipe, and we need to make sure we take a safe and practicable approach to the repairs.

“In the meantime, the excavation has been safely enclosed by barriers and traffic is able to flow freely past the spot.”

Sewers can often be repaired quite quickly when the problem is found. The drainage contractor will assess the damage and suggest a suitable repair.

Part of the South Circular in London is to remain closed for a further week at least, after emergency repairs are made to part of the sewer system.

The sewerage system that is beneath London Road in Forest Hill collapsed last Friday and needs to be rebuilt. Diversions are in place around the work which is near Sainsbury’s supermarket and it is estimated the works will not be complete for another week at least.

Thames Water is carrying out the repairs to the drainage system and are rebuilding part of the sewer. A spokesperson for Thames Water stated:

“The rebuild of this section of sewer is expected to take about two weeks.

“We are really sorry for the inconvenience this is causing road-users.”

Although on a smaller scale than the sewer system on London Road, a collapsed drain that leads from your home to the public sewer system can have devastating consequences for the homeowner. The waste water will not be able to flow into the sewer and in the worst cases can back up into your home.

If you do have a damaged waste pipe, it’s important to instigate a repair quickly. A drainage contractor will asses the damage and be able to offer the most appropriate solution.

Blocked drains need prompt attention to stop the problem worsening. A blocked drain can stop the waste water from your home reaching the public sewer, meaning that the waste may flood into your garden or in the worst cases, into your home.

A professional drain cleaning engineer can assess your drain blockage and offer a suitable solution to the problem. They will likely first suggest drain jetting, which uses a high power jet of water down the drain to disperse the clog. When the blockage is removed, the drain engineer will need to find the cause of the blockage and suggest a suitable remedy.

Most drain blockages are caused by putting non-biodegradable products into the drainage system such as nappies, sanitary wear, contraceptives, oils and fats and garden debris. If your blockage was caused by one of these items, it is likely no further action will be needed. However, if the problem was caused by a collapsed drain or a crack in the pipe where waste can collect, further work may be needed.

It’s not always the case that the drainage company will have to dig an area to replace the drainage pipe. In some cases, the drain can be lined using a drain liner, which is inserted into the damaged section of pipe and so making the repair.

The Drainage Consultants were approached and asked to submit a price for the clean and survey of the below ground drainage system at Manchester Airport. As part of this project, it was necessary to identify interceptors.

After quoting, the Drainage Consultants were considered the best for the job and will begin work in a few weeks’ time. The first step is obviously the clean and survey, after which a report will be compiled for the client, highlighting any problems and defects together with a price for repairs.

A clean and survey involves first jet washing the drains. Water is forced through the drainage system at high pressure, removing any build-up of grime and debris. This is a safe method that ensures cleaner drains without posing any risk to the pipework.

Having carried out this first stage, the drains are then surveyed using CCTV. A camera is passed through the pipework which then transmits the images for examination. Any damaged or suspect areas can then be noted and added to the report.

When the client receives the report, they can then judge whether additional work is needed or not. If it is, it is a straightforward task to go ahead and make repairs as the damaged areas have already been identified.

The Drainage Consultants were recently hired to carry out a clean and survey of drains on an industrial site in Dukinfield. The job involved cleaning the system with high pressure water jets before examining the pipework via CCTV.

This is a fairly typical way of starting a job, the aim of which is to maintain the pipework and identify any flaws in it as well as any potential issues that may ensue. During the course of the work, a problem was identified with a culvert watercourse running underneath the units. The culvert was eight metres deep and was beginning to collapse. To deal with the problem, the culvert’s location under the units was traced and an excavation carried out around where it was collapsing. The excavation was over a 12m by 8m area, after which repairs could be made.

Having carried out the repair work, a 70m liner was then inserted. This might have been the point where many drainage companies would have left the job, but the Drainage Consultants cured the full length of the 70m liner with UV light as well. The liner is impregnated with a UV-reactive polyester resin which provides superior performance.

Drain blockages can be caused by many different things. But one of the most common reasons for blocked drains is root intrusion into the pipe. Roots from surrounding trees and plants can find their way into the drainage system near your home and can not only block the waste pipe network; but also cause serious damage to the structure of the pipe itself. A drain maintenance company will be able to perform a CCTV survey on your drainage system to determine if this is the case and will then suggest a suitable remedy.

If you have a drain blockage that is caused by root intrusion, a professional drain maintenance company can remedy the problem by inserting a rotating cutting device powered by a high pressure jet of water into the pipe to remove the roots and restore the pipe back to its full waste carrying capacity. The roots commonly find their way into the system through the joints between the different sections of pipe. However, depending on the results of the CCTV survey, the pipe may also need a liner repair or replacing completely.

Root infiltration can cause untold havoc to the homeowner, so drains should be checked on a regular basis by a drain maintenance company to check for potential problems.

If you are the owner or manager of a large industrial or commercial facility, you will need to make sure that the waste water systems you have on site are maintained and are always in good working order. The large number of people you may have on site mean that disruptions to the drainage system will have a great impact on their ability to work and hence your ability to make a profit due to downtime. This is why it is so important that you have a drain maintenance contract in place.

As part of your maintenance contract, the drainage contractor will visit your premises out of normal working hours to carry out any preventative or remedial work. They will also be able to carry out detailed surveys of your drainage system and be able to advise you if repairs or replacement sections of the system will be needed in the future. Drainage contractors are available to call whenever you have a problem and can offer emergency services 365 days a year if necessary.

Having disaster recovery systems in place is now commonplace for most businesses in the UK. So, including a drain maintenance contract and an emergency call out into this system is one way that you can prepare for any issue should it occur.
