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.

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

Dew ponds

Dew pondsA 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 pondor 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.

Sources of contamination

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.

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.”

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.

Manley water supply

Water ramBasic 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 Spring...

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.

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 , Billy Booth
