How much alkaline water should you drink per day? The short answer: most healthy adults can drink alkaline water just like regular water.
Whether you have just discovered alkaline water or you have been drinking it for years, one question comes up more than any other: how much should I actually be drinking each day? The good news is that the answer is straightforward for most people.
Most health authorities, including the South African Department of Health, recommend that adults drink roughly 2 litres (about 8 glasses) of water per day. That baseline accounts for an average adult in a temperate climate with moderate activity levels.
Factors that can push your requirements higher include hot weather, physical activity, pregnancy, breastfeeding, and illness. The key principle remains the same regardless of your water source: consistent hydration throughout the day is what matters most.
A simple check: if your urine is pale straw-coloured and you rarely feel thirsty, you are likely well hydrated.
Yes. Alkaline water with a pH between 8 and 10 is widely regarded as safe for daily consumption by healthy adults. You can use it as your primary drinking water and follow the same volume guidelines you would for standard filtered or purified water.
Designer Water pH10 contains naturally occurring minerals including calcium, magnesium, and potassium, which contribute to its smooth taste. In a blind taste test, 97.9% of participants preferred it over competing brands, making the transition easy for most people.
Your ideal daily intake depends on how active you are. The table below provides a practical guide. These are general ranges for healthy adults and not a substitute for personalised medical advice.
| Activity Level | Daily Intake | Glasses (250ml) | Notes |
|---|---|---|---|
| Sedentary Desk work, minimal movement | 1.5 – 2L | 6 – 8 | Baseline hydration for most adults |
| Moderately Active Light exercise 3–4x/week | 2 – 2.5L | 8 – 10 | Add 250–500ml on workout days |
| Active Daily exercise, physical job | 2.5 – 3L | 10 – 12 | Spread intake across the full day |
| Athletes / Intense Training High-performance sport | 3 – 4L+ | 12 – 16+ | Adjust based on sweat rate and conditions |
South Africa’s climate also matters. During Highveld summers, you may need 500ml to 1 litre more than the ranges above. Listen to your body and drink before you feel thirsty.
If you are new to alkaline water, a gradual transition is the most comfortable approach. Most people adjust within a week or two.
Replace a portion of your regular water with alkaline water. Morning and midday are a good starting point.
By now your body has adjusted. Start using alkaline water for most of your daily intake.
You can now drink alkaline water as your primary water source. Match the intake to your activity level from the table above.
Once you know how much alkaline water you should drink per day, the key is consistency.
Use this simple formula as a starting point to estimate your personal daily water needs:
Alkaline water is safe for the vast majority of healthy adults, but certain situations warrant extra care:
When in doubt, ask your healthcare provider. This guide provides general wellness information and is not a substitute for medical advice.

Drinking excessive amounts of any water, including alkaline water, can dilute electrolytes. For most healthy adults, sticking to the general recommendation of 2 to 3 litres per day is a sensible approach. If you have kidney conditions or take certain medications, consult your healthcare provider for personalised guidance.
Yes. Many people start their day with a glass of alkaline water first thing in the morning. There is no evidence suggesting it is harmful on an empty stomach for healthy adults. As with any dietary change, listen to your body and consult a healthcare professional if you have concerns.
For most healthy adults, drinking alkaline water daily is considered safe and is similar to drinking regular water for hydration purposes. Designer Water pH10 is SANBWA-accredited, ISO 22000-certified, Kosher, and Halal, meeting the highest quality and safety standards. If you have a pre-existing medical condition or take prescription medication, check with your doctor first.
There is no specific “magic number.” The most important thing is consistent, adequate hydration. Most people who switch to alkaline water report that they enjoy the taste, which naturally encourages them to drink more. Start with the guidelines in the table above and adjust based on how you feel.
Older children and teenagers can generally drink alkaline water as part of their normal hydration. For infants and very young children, always follow your paediatrician’s specific guidance on hydration.
