Big Blue

More than Just Filtered Water
We don’t supply filtered bottled water, we supply Ultra Purified and Artesian Mineral Water…But if you want just filtered water, then we suggest one of our plumbed-in filtered systems, which we guarantee will have the highest filtration system installed under the hood. Find out more about our bottled water and filtered water systems.

Dehydration Can Make You Fat and Sick –
Why You Need to Keep
Fully Hydrated


Dehydration causes brain tissue to lose water, causing your brain to shrink and pull away from your skull. This triggers your pain receptors, giving you a headache. Dehydration also causes a drop in blood volume, which lowers the flow of blood and oxygen to your brain, also causing headaches.


Dehydration causes fatigue as it results in enzyme activity in the body slowing down, causing you to feel tired and sluggish.

Asthma and allergies

Asthma and allergies are due to irritants causing an inflammatory reaction. When you are dehydrated your body restricts airways to conserve water, during this process histamine production increases, increasing the risk of allergic reactions.

High Cholesterol

When your body is dehydrated it produces more cholesterol to prevent water loss from the cells.

Bladder or Kidney Problems

When your body is dehydrated it accumulates toxins and acid waste, creating an environment where bacteria thrive and potentially causing bladder and kidney problems.

High Blood Pressure

Blood is normally about 92% water when the body is fully hydrated. When you become dehydrated your blood becomes thicker, causing resistance to blood flow and elevations in blood pressure.

Skin Disorders and Signs of Aging

Dehydration impedes the elimination of toxins through the skin, making the skin more vulnerable to disorders, including dermatitis and psoriasis, along with the signs of aging, such as premature wrinkling and discolouration.

Digestive Disorders

Dehydration and a shortage of alkaline minerals such as calcium and magnesium, can result in digestive disorders, such as ulcers, gastritis and acid reflux.

Weight Gain

Dehydration can affect the body’s ability to burn off fat and slow down your metabolism, leading to excess fat retention. Drinking cold water can help speed up your metabolism and burn off calories.


Your body draws much of its water from your colon to provide fluids for other critical body functions. Without adequate water waste products move through the large intestines much more slowly, or even don’t move at all, resulting in constipation.

Joint Pain or Stiffness

Joints have cartilage padding which is made up mainly of water. When your body is dehydrated your cartilage is weakened and joint repair can be hindered, causing pain and discomfort.

How Much Should You Drink

Your body is 75% water – On average you should drink 8 8-ounce glasses of water every day – and more if you are doing exercise or if it is a hot day.

Why do people enjoy drinking our water ?

Some say Big Blue water has the best tasting water they have ever drunk, we say we don’t make water, we just make it taste like it should! JUST WATER – No fluoride, and no chlorine!!


Taken from the municipal supply for our Auckland and Hamilton distribution, our water is purified in six steps by the process known as “Reverse Osmosis” to remove potentially harmful contaminants or additives. Reverse osmosis is an advanced water purification method which was invented by the US Navy in the 1970s to create pure drinking water from sea water for its fleets.

  • Step 1Pressure pushes water through an activated carbon filter to remove any chemicals like chlorine which are often added to water by treatment plants in an effort to clean the water
  • Step 2Water is then sent through a high density sediment filter and then another pre filter.
  • Step 3Then 150-225psi of pressure forces the clean water through a semi-tight RO membrane which has holes that are 1 Millionth of a Millimetre wide which only a water molecule can fit through, contaminants are to big to fit through the holes and are discarded via a waste pump. The water that is received on the other side of the RO membrane is known as “Pure Water”.
  • Step 4Water that is pure enough to make it through the entire Reverse Osmosis process is then stored in a completely sterile steel holding tank which has been specifically treated for holding food grade products.
  • Step 5Water is pumped from the UV Steriliser straight down into our bottling room and using a special 3 stage sterile flo-tap and hose combination, and it is pumped directly into a one of our UV resistant, refillable and recyclable 15L bottles and sealed air-tight using our sterilized non-spill caps.
  • Step 6 Once the water is pure and bottled it is date stamped and stored ready for our free water delivery service, often the very next day.
Wellington Region – Petone Gold

Our Wellington water is sourced from artesian springs. Clean and pure from natural filtering it has a distinctive and famous taste –
it also has no fluoride added to it.

An artesian spring is different from a typical spring in that the water is enclosed by thick layers of sand and rock that prevent the introduction of man-made contaminates. Slowly over the years water is forced through the sand and rock stripping the bacteria and dissolved solids off the water molecules.

Artesian springs are tapped by boring through the rock and sand so that as water is forced upwards, where it is collected. Our Petone bottling plant operates in the same way as our Auckland plant but without the need to pass through a Reverse Osmosis Membrane, our process does remove a number of factors that change the taste of the water though including chlorine.

Canterbury Region – Southern Goodness

Our Canterbury water is sourced from deep artesian springs. Canterbury Artesian Water begins its journey from the most isolated and untouched part of the world, the Antarctic. Water vapour is lifted up by the fierce katabatic winds, travelling across the ice-cold South Pacific Ocean before falling as rain, high in the world famous Southern Alps of New Zealand one of the planets most isolated locations and internationally acclaimed as the source of one of the purest natural waters in the world. The water then spends 70 years (that’s a rough estimate by the way!!) being naturally filtered to purity on its way to deep aquifers under the Canterbury plains which have been known for centuries for the quality of its wonderful water. Reflecting this our plant in Christchurch is the least technical of our three plants incorporating high quality activated carbon filters, pre-filters and UV light before being bottled in our sanitised and UV resistant bottles.
