The process of distillation does sterilize water, but it also removes the minerals from it. Most bottled drinking water like Dasani is sterilized using UV light or ozone because it destroys bacteria without affecting the taste of the water, but they actually add certain minerals to give the water a good flavor. In the scientific laboratory you may often encounter "deionized" water where minerals are removed by filters. This is often used for washing glassware or in chemical and biological scientific processes where the minerals naturally occuring in water might interfere with the reactions, but it doesn't necessarily need to be sterile.

Drinking distilled water is quite common. The use of distilled water as drinking water has been shown to be healthy[citation needed] and, in many cases, safer than filtered water[citation needed].
Many beverage manufacturers use distilled water to ensure a drink's purity and taste. Bottled distilled water is sold as well, and can usually be found in supermarkets. Water purification, such as distillation, is especially important in regions where water resources or tap water is not suitable for ingesting without boiling or chemical treatment.
Water filtration devices are common in many households. Most of these devices do not distill water, though there continues to be an increase in consumer-oriented water distillers and reverse osmosis machines being sold and used. Municipal water supplies often add or have trace contaminants at levels which are regulated to be safe for consumption. Much of these additional contaminants, such as volatile organic compounds, fluoride, and an estimated 75,000+ other chemical compounds[citation needed] are not removed through conventional filtration; however, distillation does eliminate nearly all of these pollutants.
Distilled water is also used as drinking water in arid seaside areas which do not have sufficient freshwater, by distilling seawater. It is quite common on ships, especially nuclear powered ships, which require a large supply of distilled water as coolant. The drinking water is produced in desalination plants, although it is very expensive due to the large amount of fuel needed to boil water. Alternative technologies like reverse osmosis are becoming increasingly important in this regard due to their greatly reduced costs.
Sterile water palpule is a method of pain relief with particular application for childbirth.
Four injections of sterile water are made into the skin at specific points on the lower back. The effect is immediate, last for a few hours and can then be repeated if necessary.

Distilled water has been boiled and the vapor condensed. This removes the minerals. Sterile water has been heated to a high temperature to kill the microorganisms.

Jabberwock has the right of it-
Distilled water has been distilled:

(It has had the impurities removed)
Sterile water has been sterilized, by heat, chemicals or radiation, so that everything in it is still there, but DEAD (if it was living)
