CHOLERA
I have been doing a lot of work on the Kent Water Company in Greenwich over the last couple of weeks leading up to a talk one evening. When I was going through my records – and I know I’ve written a lot about The Kent Water Company in Weekender - I could no article specially about the two small outbreaks of cholera in our area. So I thought I would do that this week and hope that my records are accurate and I haven’t done it before.
The first cases of cholera appeared in London in 1831 but it was not then recognised that it was caused by bacteria in the water supply. There was however growing concern at the quality of water supplied by some companies –although our Ravensbourne water from Brookmill was seen as particularly good.
From the early 19th century water companies began to install methods of cleaning river water by passing it through a sand filter. This was first developed in London by the Chelsea Water Works in 1829. Kent Company at Brookmill constructed a filter bed and began to supply filtered water from 1844 – but they had to take out a mortgage on the works to be able to afford it. Later more filter beds and a settling reservoir were added and sited across Ravensbourne from the Brookmill works. The Company’s clean and sparkling water led to increased custom and eventual great prosperity.
There were more cholera epidemics in 1837 and the government appointed Edwin Chadwick to undertake an enquiry info sanitation. He showed the link between poor living conditions and disease. Medical thinking of the day attributed infection to foul smelling air.
There was another cholera epidemic in 1848.
In 1849 John Snow a London-based physician, published a paper ‘On the Mode of Communication of Cholera’, in which he suggested that cholera was not transmitted by bad air but by a waterbourne infection. Little attention was paid to him.
Many improvements were undertaken at Brookmill in 1850 following an enabling Act of Parliament which allowed then to increase capital to spend on engines, reservoirs and filters. The two filter beds were supplemented by a settling reservoir- which was on the same side of the river as the mill. Further land was purchased at a great price.
In November 1850 the Kent Company agreed to pay the Metropolitan Commissioners of Sewers £5,000 to prevent them throwing the sewage of Sydenham into the small river Pool, a feeder of the Ravensbourne. They also paid the Board for a new sewer to remove all house drainage from the Ravensbourne
In 1851 a Government commission was set up composed of ‘three chemical gentlemen’ – Professor Thomas Graham FRS, W. A. Miller FRS, and Professor A. W. Hofmann FRS. Their report detailed the chemicals found in the River Thames water. They also pointed out the problems of contamination in the Thames within the tideway and they said extraction from it should cease. They also complained about the ‘hardness’ which they found objectionable. Kent Company’s engineer, William Morris, said he was ‘well acquainted with their report’, Professor Graham had analysed the Kent Company water and reported it as ‘always delivered bright and clear.
In 1853 there was another cholera epidemic.
There is the famous story of how John Snow
removed the handle of the Broad Street pump thus isolating and removing a major
cause of cholera and proving that the infection was water bourne. There is even
a Wetherspoon’s pub named after him. What had happened was that in August 1854
cholera broke out in part of Soho.
Within three days 127
people on or near Broad Street died. Many people fled the area but within a
week more than 500 people were dead. Snow talked to locals and found they had
all used the public water pump on Broad Street and he persuaded the local parish
authorities to remove the handle of the pump and as infections subsided he had
proved his point that cholera was water bourne from a specific source..
CHOLERA IN DEPTFORD
At
around the same time John Snow did a study in Deptford where the water
supply was from the Ravensbourne and supplied by the Kent Company.. Around 90 people had died within a few
days - but the river water was known to be clean, and there had been no
previous outbreaks of cholera here.
Snow said “I went to Deptford, to make inquiries
respecting a most fatal outbreak of cholera .... being confined to two streets’. His investigations showed that this outbreak
was caused by an accidental contamination of the drinking water, which had
happened ‘in an unusual manner’.
People in the two streets
where about ninety deaths from cholera occurred in a few days, used water supplied
by the Kent Water-works. Residents had
told Snow that over the past few weeks the water generally smelt highly
offensive. They had therefore thrown
away a few pailfulls and only used what was pumped later - which was pretty
clear. Snow concluded that some leakage
had taken place into the pipes - there were no sewers in these streets, and the
refuse of all kinds saturates the ground in which the water pipes were laid.
This problem was dealt with but soon there was a terrible problem in Charlton
Lower Charlton seems the most
unlikely place to have a water works.but in 1857 a deep well was sunk at North Charlton
alongside the Woolwich Road by another new water company –Charlton Pure
Water Co. - - who. built a pumping
station and installed a ‘Cornish Engine’ -
a steam engine from Harvey & Co. of Hayle in Cornwall.. It was soon‘pumping
its daily supply of water from the chalk well on the margin of the marsh’. It was
‘built it appears by speculating builders on land entirely unfit’. .. ‘on the
marsh and the water soaking from the tidal ditch is seen through the floors ..
market gardens covered with the foulest manure ..... deep wide cesspools’.
There are vivid descriptions of houses where the water supply had been cut off.
Soon problems with the new company led it
being taken over by the Kent Water Co
In 1866 cholera struck.“A middle aged man from one
of the cottages ... his wife is ill and a young lodger has just died of cholera
...............a West street six or seven deaths ......... a man and woman are
quarrelling ......... a dead child has just been carried from the house’..a
‘few doors on is a decent woman in a clean house whose son, a young gardener,
was attacked by cholera in the morning at six o clock and died before noon - his two boys were running about and the mother was from home’.
In West Street and Harden's Manorway ‘men were ill in great numbers, and several died within a few days. Men were sick at home’ and sudden deaths by cholera caused “inconceivable consternation among the women”.
Nearly every house in this district used water from the Charton Works. This came from a stand pipe which functioned for a short time every day; and people collect the water in ‘vessels of various kinds, dirty or clean’. There was no water supply to outdoor toilets and in many cases the water had been cut off ‘because the landlords or the tenants have at some time or other neglected pay the rate’.
It was said that this would not do because
Woolwich ‘is one of the principal military stations of England. There is large
force of artillery, amounting to more than 5,006 men. The dockyard employs many
men; the great arsenal of the empire full of artisans in Government employ.’
Thus ‘the health of the place in time of war is of vital importance.’
So the almost new pumping station was taken out of use because the well was
‘becoming contaminated with river
water’
The waterworks pump
house was not demolished until the 1950s. Photographs show a tall ‘Gothic ‘
building looking very much like a waterworks, with a tall chimney. It was
leased to a builder’s merchant’s and subsequently to other industries. By the
1950s when it was demolished it had been
in use by the Grafton Engineering Co.
This terrible episode seems to have been the only time the Kent Company were closely identified with an outbreak of cholera perhaps in the same way that they couldn’t really be blamed for the Deptford outbreak, it wasn’t entirely down to them. Kent Company water became a standard of purity for all London and cholera would not be an issue in their area. What a pity that it happened at all;
