Where is the Pure Water

An estimated 3 billion people do not have access to proper sanitation and more than 5,000 children die daily as a result of diseases related to dirty water.

“There are more people without proper sanitation this year than last year and there will be more again next year,” said a water and sanitation expert at the World Health Organization.

Tap water is now treated purposely with several well-known chemicals (Chlorine, Flourine, lime, copper sulfate, aluminum sulfate, sulfur dioxide), and infected by accident with hundreds more. Remember that the by-products of civilization are everywhere. Road salt, agricultural chemicals, fertilizers, pesticides, rubber, motor oil, paint thinner, it’s just a matter of time before these pollutants make their way into the water sources. Example: Atrazine, a corn pesticide. If there were not so many bacteria that eat at least some of this stuff, we would be in much worse trouble.

Each human being needs between 2 and 3 quarts of water each day, from all sources (a tomatoe, for example is about 90% water). That means about 16,000 gallons of water in a lifetime. Some recent developments in water transport and treatment have presented more problems than they have solved.

Take water softening: Using sodium to displace calcium and magnesium is good for the pipes, but not good for you. Sodium causes fluid retention, gas, heartburn, and cardiovascular problems.

Brief History

So when the water tap is turned on in the home for that special pot of tea or coffee, or for the invigorating hot tub or shower, and the great valves are opened in industrial establishments or to recharge swimming pools, the water must come from nearby rivers, lakes, or wells tapping the aquifers. The surface freshwater is recharged with rain and other precipitation, but because of the great depth of some aquifers, they cannot be recharged.


Reverse Osmosis

Also with Reverse Osmosis systems there is a constant flow of water passing over the membrane to wash it and this flows to the waste pipe. The basic difference in water filtration is of course the size of the pores or holes in the filter itself. In practice say we install a basic 3-stage system comprising a 5micron, a .9micron and a chlorine filter.


Some Figures

A single toilet flush is more than most people in developing counties use for drinking washing and cooking in one day. 150 gallons of water are used in the growing/prodution of a loaf of bread. At least 250 gallons of water are needed to produce one ream of paper. 1 in every 6 people in the world lack access to safe drinking water. When you use the toilet you use: 9 litres. When you use the washing machine you use.
