City Drains London drainage service excels where other blocked drain clearing engineers fail!

One of the qualities that stands out when dealing with London City Drains and which our customers agree on, is the go for attitude and determination to solve the drainage problem at hand.

One job recently undertaken in central London was for a solicitor firm whose drains were located in their basement offices.

Over the years a score of London drainage service firms had been called out to try and solve the drain problem of the horrendous bad smells that were emanating from their basement office area and which was affecting all those that worked in that confined zone.

A second problem was that of a blocked basement kitchen sink waste pipe. This again had been dealt with on numerous occasions but the drainage problem never solved.

The problem at hand was not an easy one as the basement was carpet tiled and there was only access to one manhole. This was the manhole that all the other drainage contactors had been heading straight to without ever investigating any further.

Our drainage engineer decided to approach the job with a different attitude altogether. The first thing he had to investigate was whether there were any other manholes available in the basement. His many years of experience told him that there had to be a main interceptor in the basement somewhere. It was crucial that this be found as this would give a clear indication of whether:

A) The smell was due to a blocked drain
B) Whether the drain had an eye cap fitted

This had never been undertaken by other London drainage engineers, as was confirmed when the drain was located and exposed. The drain, although it was running perfectly and there was no blockage, had no eye cap fitted. *One was immediately fitted and one of the problems resolved.

The problem of the blocked kitchen sink waste pipe was now addressed;

The previous London drainage engineers had all tried the same method and had failed in their endeavour. They would go direct to the only exposed manhole and use the high pressure jet up a side connection, which they thought was the waste for the kitchen sink. This method failed and no time was taken to investigate further the possible reasons for this failure.

London City Drains Engineer tried a different approach. Again, all his years of experience told him that obviously something was not right. After removing every item under the sink area, he traced the waste pipe and found that this was going directly into the floor and it would be normal to assume that this would be connected into the side connection that other engineers had tried drain jetting up and had failed. The problem was that it made no sense, as there was a pool of water on the floor and this was not normal unless there had been some form of flooding.

After obtaining permission from the office manager, the engineer removed the floor lino and found that there was an old rain water gully which had been sealed with a metal cover; the kitchen sink waste pipe was running into this gully. The gully as it turned out was an expired soak away and this particular area was originally an outdoor area that had been rebuilt over to accommodate for the new offices. The builders who had connected the kitchen sink waste pipe into the gully had made a serious blunder! This was not connected to any foul drain and there was no way the waste from the sink could flow away. The problem in the end was remedied by cementing over the old gully and realigning the kitchen waste pipe so it would flow directly into the manhole drain.

Because the waste in the old gully had just been sitting there for so long, this had also gone stagnant and was another contributing factor for the bad smells.

All the problems were effectively dealt with and the office workers were very relieved to be working under healthier conditions.

• The eye cap which is normally fitted on the rodding eye in the main interceptor serves to stop bad smells and rats from coming up from the main sewer on the road into your property. Most properties in London do not have one fitted.

If your property is suffering from bad smells then this could be the reason why.

Drains cleared fast – customer review

Here’s a recent review from a London City Drains customer:

“I recently called out City Drains and was pleasantly surprised at the speed in which they responded, 21 minutes!

Furthermore, they demonstrated a professional attitude at all times and were very thorough in their work. At the end of the jet clean they went so far as to carry out a cctv survey of the drain, free of charge! just to make sure the job was completely done.

Their rates are fair and I have received a more than adequate service. Well done boys!”

The Simpsons Syndrome – advice from London City Drains

It’s funny how people seem to make the same mistake over and over and usually never learn first time round. Animals do, and we are supposed to be the logical ones?

Sometimes you come across a job which by right could be put right first time round. But its funny how, because of peoples perception of tradesmen, and I must admit, also from an economical point of view, people aren’t willing to spend that bit extra to correct a problem with a permanent solution.

Instead, they choose to call you out again and again and again for the same problem. In the end they think that you’re not doing the job correctly and choose to call somebody else who may rip them off or if they are lucky have the problem corrected once and for all by following the recommendations that you gave them to begin with.

What is the problem with this scenario?
Well let’s begin with an economical point of view.

For example: An engineer gets called to an emergency blockage. The blockage is cleared as fast as possible. The recommendation given is to have the line jet cleaned otherwise your drain will re-block in no time at all. It involves 1 extra hour of work. The customer decides not to go along with the recommendation and two months later calls you out again. Again you clear the blockage as quickly as possible and you charge the customer again as the recommendation wasn’t followed. This happens several times throughout the year. By the end of the year, the customer has paid for the same job 4 or maybe 5 times!

If they had followed your recommendation to begin with, he/she would not have had to call you out several times and they would have saved a lot of money on emergency call outs. You don’t have to be smart to work that one out.

Let us not forget also the calling out of the other contractor; I wonder how much he charged to get the job done? The same or more than if they had gone through the contractor’s original recommendation when it was first made, that’s for sure.

This brings me to the second problem scenario. And that is the false and unfair perception by the customer of the first contractor, who only tried to help by giving you the best advice to begin with and ended up being the bad guy. All because again the recommendation wasn’t followed through.

The moral of the story: London City Drains is here to help you help yourselves.
Listen to our advice and act on it, you wont regret it!

London Drainage cctv survey – blocked drain due to kinked pipe

Drainage London | CCTV Drain survey footage – London Drainage Service

We’ve added a report of a recent drainage survey to the City Drains London website.

In this example we inspected a 4 inch PVC drain pipe at a house in London – the customer was suffering a blocked drain which needed immediate attention. 

London drainage inspection service

The cctv drain survey showed that the blocked drain was caused by a kinked pipe which caused water retention and flooding.

Drain repair was possible by excavating the blocked pipe, and realigning the drain to the correct angle, allowing the drain to flow freely and preventing any futher drain blockages.

You can see the full cctv drain survey footageplus the drain schematic and drainage service report by visiting the London drain inspections page on our website.

Riverside Sewage Treatment Works Plant Will Run Entirely From Renewable Energy

Thames Water is proposing to upgrade its sludge treatment facilities at Riverside Sewage Treatment Works, in Rainham – which will enable the plant to treat the solid waste left behind after the sewage treatment process and turn it into enough renewable energy to power the entire site.

The proposed upgrade will be located entirely within the existing sewage treatment works and will involve refurbishing existing digestion tanks and building new sludge thickening, de-watering and storage facilities. All measures are being taken to ensure the works will have no effect on odour.  All process tanks and sludge storage areas will be covered or enclosed in buildings.

Sludge will be treated through anaerobic digestion, whereby solid waste is broken down in enclosed tanks in the absence of oxygen. The process generates renewable energy, in the form of biogas (methane) which can be used to run engines and turbines for heating and electricity. The process also leaves behind a nutrient-rich solid which can be used as fertiliser.

A planning application will be submitted in May 2008 and subject to approval, construction will begin in early 2009 with works due for completion by 2010.

Investment Plea for London Sewers

Investment plea for London sewers

london blocked drain and sewer
Investment is urgently needed to upgrade London’s drains & sewers and reduce the threat posed by climate change and flash floods, experts have warned.

The severity and regularity of flash floods is expected to increase as more of London’s green spaces are concreted over and the population rises.

In 1859 Sir Joseph Bazalgette used 318 million bricks to create an underground grid to transfer London’s sewage to the east of the city.
It is now processed and turned into electricity at treatment works in Beckton and Crossness.
London’s unusual combined sewer system deals both with water flushed from homes and incoming rainfall from drains.

Climate change is expected to increase the regularity and severity of flash floods, placing greater demands on the system.

This will be compounded by the vanishing areas of green spaces able to soak up rainfall and a 800,000 population increase predicted by 2016.

Video of offset blocked drain – London drain inspection survey

Here’s another movie of a blocked drain London City Drains cctv survey.

In this example our London drain engineer was making a cctv survey of a 4 inch diameter earthenware/cast iron drain at a home in London.

As the cctv survey footage shows, the drain is misaligned, meaning the section of drain pipe must be replaced to prevent a future drain blockage or flooding problem.

The drain survey video footage, drain survey inspection report and drain schematic can be viewed on our london cctv drain inspection survey page.
