This document provides information about various water sources and characteristics. It discusses modern water usage and consumption rates. It then describes different types of water sources like dew ponds, wells, springs and reservoirs. It provides data on rainfall amounts in different regions of the UK. It also discusses water quality indicators and contaminants. Case studies are presented on outbreaks of cholera from contaminated water. Details are given about specific mineral water sources from locations in the UK, Georgia and France.

4. Water consumption
Modern Water usage
45 – 100 m3/person/year
Drinking Water
2-3 litres/day
Approx. 0.5 to 1 m3 /year
Since 1900 water consumption in
Europe has gone up 500 fold.
5. Water usage 1 m3
= 1000 litres = 220 gallons
25 metre pool; 1.5 metres
deep; lane 1 metre wide
= 37.5 m3/lane
So 1 lane of the pool is
enough drinking water for up
to 75 people for a year.
It takes about 1,000 litres of water to produce 1 litre of milk
(includes irrigation, drinking, cleaning of cows and equipment, waste disposal etc.)
It takes 5,000 - 20,000 litres of water to produce 1 kg of
meat
It takes 500 - 4000 litres of water to produce 1 kg of wheat
10. Dew ponds
A dew pond is an artificial pond usually sited
on the top of a hill, intended for watering
livestock.
Dew ponds are used in areas where a natural
supply of surface water may not be readily
available.
The name dew pond (sometimes cloud pond
or mist pond) is first found in 1865.
Despite the name, their primary source of
water is believed to be rainfall rather than
dew or mist.
33. Characteristics of water
The following is a list of indicators of water quality:
Alkalinity
Colour of water
pH
Taste and odour
Dissolved metals and salts (sodium, chloride, potassium,
calcium, manganese, magnesium)
Heavy metals and metalloids (lead, mercury, arsenic, etc.)
Dissolved organics
Radon
Pharmaceuticals
Hormone analogues
Microorganisms

moderately soft 50 – 100
slightly hard 100 – 150
moderately hard 150 – 200

very hard over 300
39. Cholera in Soho
In August 1854, a major
outbreak of cholera struck
Soho. By 10 September,
500 people had died.
John Snow eventually
linked the outbreak to
contaminated water. The
local council disabled the
well and the outbreak
declined.

46. Water from the Republic of Georgia
“Borjomi spring water is beneficial
in the treatment of diseases due to
its mineral properties.”
“Borjomi mineral water has been
used for centuries to treat chronic
gastritis, gastric and duodenal
ulcers, chronic diseases of the liver
and bile ducts, gallstones, kidney
stones, urinary tract infections and
respiratory diseases.”

48. Water from the Lake District
• The Willow aquifer is the source of the legendary Holy Well of
Cartmel dating as far back as the 12th Century.
• Filtered through what was once a white willow forest, and
limestone, willow water has a unique mineral composition
including Calcium and Salicin.
55. Water ram
Basic components of a hydraulic ram:
1. Inlet — drive pipe
2. Free flow at waste valve
3. Outlet — delivery pipe
4. Waste valve
5. Delivery check valve
6. Pressure vessel
Hydraulic Water Ram systems need no external source of power --
the force of moving water gives them the power they need.
They are extremely simple, with just two moving parts

The village of Tattenhall,
beneath Cheshire's beautiful
Peckforton Hills, is home to the
spring which has provided this
pure, clear and refreshing water
for over 70 years.
The original borehole for the
water was sunk in 1938, and
over the years provided millions
of litres of fresh water. A new
borehole was created in 1993 to
meet the highest modern
standards of production.
58. Frodsham Mineral Water Co
1900 to 1913
Two cousins by the name of Ellison
and Corker founded a mineral water
company in 1888. It was behind
Millbank Cottages, off Main Street.
It was renamed Frodsham Mineral
Water Co. in 1912 and many of their
old bottles with 'glass alleys' in the
neck still remain. The man holding
the horse is Joe Ellison, a son of the
founder, and the boy on the cart ,
