Good Bog? Bad Bog? Public Toilets!

London City Drainage reports on toilet phobias:

Phobia of public toilets

The National Phobics Society has revealed that more than four million Brits suffer from a toilet phobia of some kind. People up and down the country are going potty with anxiety because they always need to find a stress-free place to do their business.

Problems range from a mild dislike for public loos to complete fear of leaving the house in case a suitable toilet can’t be found. People have even turned down job offers because the toilet facilities are not up to scratch.

Shy Bladder Syndrome, when people have a fear of urinating in the company of others, and bashful bowel syndrome, which is the inability to defecate in public toilets, are two of the key causes of toilet phobia.

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.

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.

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.

Until around 1800 the river Thames had supported a large fishing industry, which caught and sold a wide range of species, including lobsters and salmon. But by 1805 only 150,000 cesspits had been built to serve London’s one million inhabitants and within a decade many householders had begun to illegally connect their overflowing cesspits to surface water drains which flowed into the river Thames, the main source of drinking water for London. The rising tide of sewage rendered it virtually lifeless – the river began to smell, especially in hot weather.
The state of the river became a well-publicised scandal that resulted in the Public Health Act of 1848. This established the Metropolitan Commission of Sewers. The new Commission quickly ordered a major survey of the London sewers, which were found to be inadequate and in major need of repair.

Outbreaks of cholera had occurred in 1832 but in 1849 a further outbreak, during which the death toll was estimated at 2,000 Londoners per week, prompted Dr John Snow and William Farr to conduct a study of the Broad Street Public Well in Golden Square, Soho. As a result, they realised contaminated water caused cholera and not “foul vapours” in the air as had been widely believed.

In an attempt to curb disease the Government passed the 1852 Metropolis Water Act. This introduced a number of measures including making the slow-sand filtration of water and the covering of service reservoirs mandatory and also ensuring that, in order to avoid proximity to sewage outfalls, the abstraction of water only took place above Teddington Lock on the River Thames.

In around 1854, the cash-strapped Commission of Sewers was replaced by the Metropolitan Board of Works whose Chief Engineer, Joseph Bazalgette, devised a sewage interception scheme designed to solve London’s sewage problem. Bazalgette planned to construct large intercepting sewers to collect flows from the existing river outfalls and convey the waste to East London. Here it could be stored in storage lagoons for up to 9 hours and released into the River on the ebb tide flow to the sea.

Bazalgette’s scheme was initially rejected on the grounds of cost, but in June 1858 the stench from the river Thames became so bad that it became impossible to continue business in the Houses of Parliament and action was demanded. As a result, the Prime Minister Benjamin Disraeli, rushed through an act allowing the Board of Works to raise the money to pay for the works by imposing charges on Londoners. Bazalgette’s plans had been so well honed that he was able to begin at once and by 1874 the system was fully operational.

City Drains Drain Cleaning Service in London

Most of London’s drains and drain pipes are antiquated and were built during or just after the Great Victorian period.

Drain cleaning in London
In most of these sewers, an accumulation of over one hundred years has resulted, more often than not the pipes find themselves full of scale, silt, debris and other foreign objects which restrict the flow of the drains and eventually lead to large build ups and more often than not, recurring blockages.

In most instances, unblocking London’s drains aren’t sufficient. Because the blockage is cleared, doesn’t mean that the underlying problem has been dealt with. Having to return to clear a blockage again in a few months time, or in some cases weeks or days, can be a very costly ordeal for the customer.

London City Drains highly recommends having your drain and drain pipe cleaned using one of their high pressure jet cleaning machines. In this way, restoring the sewer pipe back to its former glory and ensuring a perfect and odourless flowing drain for many years to come, as well as peace of mind.
Why not call City Drains on 0800 007 5309 to find out about their London drain cleaning services or for some free friendly advice.

CCTV Drainage inspection survey video now available online at londoncitydrains.co.uk

We’ve uploaded a cctv video of a drain inspection survey to the London City Drains website.

In this case, the surveyed drain was a earthenware/PVC construct – we found the drain to be in good condition with some silt build up.
