Water vs Bottled Water: Which is Safer and Why?

Introduction

Water is a basic human need that is essential for survival. However, in this modern era, we are faced with the choice between consuming bottled water or tap water. The debate on which one is safer and better for consumption continues, especially in developing countries like Indonesia. This article will take an in-depth look at the comparison between bottled water and tap water, and review various aspects related to safety, quality, and its impact on health and the environment.

In Indonesia, the use of refillable drinking water is very popular. Some drinking water depots claim to use mountain water, although such claims cannot always be verified. Meanwhile, many also use city water or well water as their water source. The challenges faced by these refillable drinking water providers are similar to those faced by households, but they have a greater responsibility as they have to serve the community well.

One of the most important aspects of refillable drinking water provision is the quality of water.

One of the most important aspects of providing drinking water is ensuring the microbiological safety of the water. Disinfection is a crucial step because it is the primary defense against the dangers of pathogenic microorganisms. In addition, drinking water providers must also pay attention to the content of unwanted solutes, which often cannot be removed by ordinary filters. Reverse osmosis (RO) technology can be a solution to this problem, but its implementation depends on the available budget.

Cleanliness and sanitation are also important factors in the refillable drinking water industry. The systems used usually consist of water storage, filters, possibly RO units, as well as UV and ozone systems for disinfection. Ozone has the advantage of having a residual effect that can help with sanitization. Generally, there is no addition of chlorine, and ozone is preferred because the odor will dissipate after a while.

Meanwhile, most domestic water systems use municipal water storage or well water, or sometimes a combination of both. This water is then pumped through a filter/softener to remove substances such as iron, silica, or other contaminants. Some households also use RO systems for further purification.

Comparison of Bottled Water and Tap Water

The debate between bottled water and tap water has been going on for a long time, with various arguments in favor of each option. Let's take a closer look at these two types of water from various aspects:

1. Quality and Safety

Bottled water is often promoted as a safer and purer option than tap water. However, this is not always the case. In developed countries with good water treatment systems, tap water is often of equal or even better quality than bottled water.

In Indonesia, tap water is often of equal or better quality than bottled water.

In Indonesia, the quality of tap water varies depending on the region and water source. Municipal water that uses river water as its source may face challenges related to contamination from domestic and industrial waste. On the other hand, well water can also contain issues such as high levels of iron, manganese, and potential bacterial contamination due to leaks from septic tanks.

Packaged water, especially from branded brands, can be of high quality.

Packaged water, especially from reputable brands, generally goes through a rigorous purification process, including filtration and disinfection. However, keep in mind that bottled water is not free from the risk of contamination either, especially if the production and packaging process is not properly supervised.

2. Regulation and Supervision

In many countries, including Indonesia, tap water and bottled water are governed by different standards and regulations. Tap water is generally overseen by public health authorities and must meet drinking water quality standards set by the government. Bottled water, on the other hand, is considered a food product and is subject to food and beverage industry regulations.

While both types of water are regulated, the level of oversight and frequency of testing can differ. Tap water is usually tested more frequently and for a wider range of parameters than bottled water. However, in some parts of Indonesia, oversight of tap water quality may not be optimal, especially in areas where drinking water infrastructure is not well developed.

3. Environmental Impact

One of the main criticisms of bottled water is its significant environmental impact. The production, transportation, and disposal of plastic bottles contribute to increased greenhouse gas emissions and environmental pollution. In Indonesia, where the waste management system is still a challenge, plastic bottles from bottled water often end up in landfills or even pollute rivers and seas.

Tap water, on the other hand, is a great source of water.

Tap water, on the other hand, has a much smaller carbon footprint. While there is energy used in the treatment and distribution process, the impact is much lower compared to bottled water production and distribution. The use of tap water also encourages investment in public water infrastructure, which in turn can increase access to clean water for more people.

4. Cost

In terms of cost, tap water is much more economical than bottled water. The cost of tap water per liter is usually only a fraction of the price of bottled water. Even with the initial investment for a household filtration system, in the long run, using tap water is still more economical.

In Indonesia, where refillable drinking water is popular, the cost is somewhere between tap water and branded bottled water. Although it is more expensive than tap water, refillable drinking water remains a more affordable option than branded bottled water, especially for the middle to lower class.

5. Convenience and Accessibility

Packaged water is often considered more convenient due to its portability. It is easy to carry and available in many places. However, reliance on bottled water can be problematic when access is limited or in emergency situations.

Tap water, while it may be possible to carry, is available in many places.

Tap water, while perhaps less portable, has an advantage in terms of accessibility. In areas with good water infrastructure, tap water is available 24 hours a day, 7 days a week. The use of refillable water bottles can combine the convenience of bottled water with the sustainability of tap water use.

Solutions and Recommendations

Given the complexity of drinking water issues in Indonesia, there is no single solution that fits all situations. However, some recommendations may be considered:

1. Public Water Infrastructure Improvement

Investment in public water infrastructure is essential to improve the quality and availability of tap water. This includes improvements to water treatment systems, renewal of distribution networks, and increased water quality monitoring. The government and local water companies need to work together to achieve this goal.

2. Public Education

The public needs to be educated on the importance of water conservation, how to use water wisely, and simple methods to improve water quality at home. Information on local tap water quality should also be more accessible to the public.

3. Stricter Regulation for Refillable Drinking Water

Given the popularity of refillable drinking water depots in Indonesia, stricter regulation and supervision is needed to ensure the quality and safety of their products. This includes standardization of treatment processes, regular inspections, and operator certification.

4. Household Filtration Solution

For households that have concerns about the quality of tap water, the use of household filtration systems can be an effective solution. This can start from simple filters to more advanced systems such as reverse osmosis, depending on the needs and budget.

One option that can be considered is the Pentair Merlin under-sink reverse osmosis system. This system offers an effective water purification solution for household use, removing a range of contaminants including microplastics that may be present in tap water or well water.

5. Use of UV and Ozone Technology

For additional disinfection, UV and ozone technologies may be considered. The Hydropro ultraviolet system for example, can be a good option for water disinfection at home or in refillable drinking water depots.

6. Well Water Quality Improvement

For households using well water, the use of specialized filter media such as Clack Birm for iron removal or Inversand Manganese Greensand can help improve water quality.

7. Integrated Water Treatment System

For a more comprehensive solution, especially for large homes or small communities, an integrated water treatment system can be considered. This could include a combination of different technologies such as filtration, water softening, reverse osmosis, and UV disinfection.

Conclusion

The debate between bottled water and tap water in Indonesia does not have a simple answer. Both have their advantages and disadvantages, and the best choice often depends on the specific situation in each region and household.
