Three Grades of Water
Utility Grade
Whether from the city or a well, this raw water is usually fine for watering outside. Treating this grade to a higher level isn't cost effective and generally not recommended.
Working Grade
When the water enters your house, any issues - such as hardness, staining, odors, etc. - should be addressed to prevent damage to appliances, fixtures, clothes, and even skin or hair. Hardness costs four times as much in soap and cleaning products and builds up on heating elements lead to increased energy expenditure and raised utility costs.
Life Support Water
The human body is approximately 70% water. Although water used for drinking and cooking is only a few gallons a day, the quality should be as high as possible.
But doesn't the Government provide safe water?
We tip our hats to those who work in our local water utilities. They have the great responsibility to provide clean water to their customers. The government tells them the quality limits they need to meet and they work hard to meet these requirements. A downfall is that chemical treatment is the cheapest way - and chemicals cause side effects. One of the main reasons that we don't get higher quality water from our local utility is that the majority of the water just goes out on the ground anyway. Yep, it's true. In summertime the majority of our treated drinking water goes to water the grass and trees in our neighborhoods. This means it is not cost effective to raise the quality of the water coming from the treatment plant.
