In Indonesia, the water refill business has become very popular as a solution to meet people's drinking water needs. However, in running this business, there are many aspects that need to be considered to ensure the quality and safety of the water provided. One crucial aspect is the selection of the right water storage tank material.

In this article, we will take an in-depth look at various aspects of the water refill business, with the main focus on the selection of water storage tank materials. We will review from the water source used, the treatment process, to the storage and distribution system. In addition, we will also discuss the challenges faced by water refill businesses and the solutions that can be applied to overcome them.

The water refill business in Indonesia has unique characteristics. Some entrepreneurs claim to use water from the mountains, although this claim cannot always be verified. Meanwhile, others use water from urban sources or wells. Regardless of the source, the challenges faced by these businesses are quite similar to those faced by domestic water users. However, there is one significant difference: as commercial service providers, they have a greater responsibility to ensure the quality of the water they provide to their customers.

One of the most important aspects of a water refill business is the disinfection process. This is a critical step to remove harmful pathogens that can cause illness. In addition, businesses must also ensure that the water they provide is free of harmful solutes that ordinary filters cannot remove. To solve this problem, many use Reverse Osmosis (RO) technology. However, the use of this technology is also dependent on the available budget.

Proper cleaning is also an important aspect of this business. Given the scale of their operations, water refill businesses should not use systems designed for household use. There are three tiers of systems that are commonly used: Residential, Commercial, and Industrial, each with different capacities.

A water treatment system for a refill business usually consists of several main components: water storage tanks, filters, RO systems (if used), and UV and ozone systems for disinfection. The use of ozone has the advantage of having a residual effect that can help with sanitization. Usually, chlorine is not added in this process, and ozone is preferred because the odor will disappear after some time.
