One important aspect of maintaining water quality is choosing the right water source. Some refill depots claim to use mountain water, although this claim cannot always be verified. Meanwhile, many also use water from urban sources or wells. Regardless of the source, the most important thing is to ensure that the water is properly treated to meet drinking water quality standards.

The water treatment process for refill businesses typically involves several stages, including:

1. Initial filtration to remove coarse particles
2. Treatment with activated carbon to remove unwanted odors and tastes
3. Reverse osmosis (RO) process to remove dissolved contaminants
4. Sterilization with UV light or ozone to kill microorganisms
