So, how much potable water is present in natural state. The answer is very little indeed. Fresh water is the main ingredient of potable water. For it to be of drinking quality it should be free of harmful chemical and life threatening bacteria. In nature the latter is extremely difficult to achieve. Rivers, lakes and ground water can very rapidly contaminated through natural animal or human waste. Now add industrialisation to the equation and you have a potentially very toxic substance. Therefore it is necessary to treat our water by appropriate means in order to remove harmful elements.
Not only is potable standard water vital for drinking and most food preparations and washing cooking utensils it is also essential for washing our bodies. Although our skin is water proof it is not bacteria proof. Therefore the importance of potable water supply to your home cannot be exaggerated.
Some facts about water.
About 70% of the earth’s surface consists of water. Approximately 97% of all the earth’s water is in our oceans and seas. Fresh water accounts for only about 3% of the total volume of the Earth’s water and most of this is locked up in ice in the Polar Regions. Now fresh water only means that it contains trace elements of salt; unlike the water in our oceans. Fresh water is very unlikely to be considered potable. In order for fresh water to be of drinking quality it must be treated for the elimination of harmful bacterial contamination.
Types of water in our homes
- White Water – potable water
- Grey Water – wastewater from washing our bodies and our clothes.
- Black Water - waste water from toilets
- Rainwater – water that falls on our property and capable of being harvested.
White Water. This is the water that is supplied by local authority or by means of your own well. If your water is from your own source then ensure regular testing. It only takes one animal spill to make your water harmful for drinking and personal hygiene purposes.
Grey Water. The waste water from your washing machine can be used for flushing toilets with the minimal amount of particle filtration. Approximately of all water used in your home is for flushing toilets.
Black Water. This is the waste water that emanates from your toilet flushing’s. This water must be treated with absolute caution. If your septic tank or percolation area is defective then your water could become seriously contaminated.
Rainwater. Nearly every dwelling is capable of harvesting rainwater. Rainwater has many qualities that your normal supply is unable to deliver. For example, Rainwater is virtually chemically free and very soft. This makes it especially good for washing clothes.
