What Is The Best PH Level For Drinking Water?

All living organisms require water as an essential and fundamental need. Natural pure water has a neutral pH of 7, placing it right in the centre of the pH scale. Nonetheless, the presence of particles in most water can alter its pH, potentially ranging from 6.5 (slightly acidic) to 8.5 (basic or alkaline). Typically, the pH of surface water systems falls between 6.5 and 8.5, while groundwater systems have a pH range of 6 to 8.5.

In South Africa, The Department of Water Affairs and Forestry (DWAF) oversees the drinking water quality, including monitoring pH levels. The DWAF advises maintaining a pH level of 6.0 to 9.0 for municipal water supplies.

What is pH Water Level?

Water’s pH level is more than just a number; it’s an indicator of potential contaminants and the water’s ability to cause health issues. For instance, water with a pH outside the recommended range may contain harmful metals or chemicals. Additionally, the acidity in our bodies, influenced by factors like diet, stress, and even the water we drink, can lead to increased health risks such as lower bone density and issues with vital organs. Acidosis, a condition resulting from excessive acidity, can have severe health implications, making the pH of drinking water a matter of concern.

What is The Best pH Level for Drinking Water?

The pH value signifies the concentration of hydrogen ions in an aqueous solution. When the pH is below 7, it suggests a greater concentration of hydrogen ions, rendering the solution acidic. Conversely, a pH above 7 denotes a reduced presence of hydrogen ions, indicating that the solution is basic. The pH scale, which ranges from 1 to 14, serves as a measure of a solution’s acidity or alkalinity; values below 7 are considered acidic, while those above 7 are deemed basic. Pure water, with a neutral pH of 7, falls in the middle of this scale.  Furthermore, pH levels are useful in distinguishing between soft and hard water. Specifically, hard water is characterised by a pH greater than 8.5, signifying it is highly alkaline, while soft water exhibits a pH below 6.5, indicating higher acidity.

What Is a Healthy pH Level for Drinking Water: Acceptable pH Levels for Drinking Water

Water with high acidity (pH below 7) may carry odours and taste unpleasant, indicating inadequate filtration and the presence of pollutants. Conversely, alkaline water (pH above 8) has been associated with health benefits, though more research is needed to confirm these claims. Nonetheless, water with a pH lower than 6.5 can erode pipes, releasing toxic metals into the water supply. While water with a pH above 8.5 is generally safe, it may taste bitter and cause skin irritations for some.

Purified Water: Acceptable Ph Levels in Drinking Water

Addressing the challenge of maintaining the perfect pH balance in drinking water, Aquazania implemented advanced filtration systems that play a pivotal role. Our system employs a nine-step process that includes an alkaline filter to neutralise acidity and an activated oxygen filter to sanitise the water, ensuring it’s free from impurities, sediment, and contaminants. By balancing the pH level and adding essential electrolytes, Aquazania aims to provide water that’s not only healthy but also appealing to taste. Contact Aquazania now!

This system ensures that water is free from unpleasant tastes and odours, making it more appealing to drink. Additionally, by eliminating the need for plastic water bottles, it offers an eco-friendly hydration solution, reducing plastic waste and environmental impact. Aquazania water coolers are designed for high-capacity use, offer a convenient and sustainable way for people to access purified, pH-balanced water in various settings.

  • Safe and Pure Drinking Water

Installing an Aquazania water filtration system ensures the removal of harmful pollutants and bacteria from your water supply, providing your family with the safest and cleanest water for drinking, cooking, and bathing.

  • Enhanced Water Taste

Filtration removes unpleasant chemicals and contaminants, improving your tap water’s taste and encouraging increased water consumption for better health and hydration.

  • Environmental Protection

By improving tap water quality and taste, you’re less likely to purchase bottled water, reducing plastic waste and its negative impact on the environment.

  • Healthier Skin

Reducing water impurities can alleviate skin dryness and irritation, improve moisture retention, and enhance skin’s overall appearance and health through better hydration.

  • Reduced Plumbing Problems

Minimising mineral deposits and contaminants in your water can lead to fewer plumbing issues over time.


Ensuring the optimal pH level of drinking water is critical for health and well-being, with the Department of Water Affairs and Forestry (DWAF) in South Africa recommending a pH range of 6.0 to 9.0 for public drinking water. Advanced filtration systems, Offered by Aquazania, align with DWAF water quality guidelines to provide safe, pure, and tastefully balanced water. These systems address risks associated with water acidity and alkalinity, supporting enhanced hydration, environmental sustainability, and overall health benefits. By embracing such innovative water filtration technology, individuals and communities can improve water quality, adhere to DWAF standards, reduce plastic waste, and achieve better health outcomes.
