SIZ Water 14 Stage Processing

Storage & pre-filtration


Stage 01

Underground Water Storage Tank

Source water is held in a covered underground tank, protected from sunlight and outside contamination.

Stage 02

Jumbo Housing Filter

Coarse sediment filtration removes sand, rust and suspended particles.

Stage 03

Raw Water Storage

Pre-filtered water is held in a dedicated raw-water tank before treatment begins.

Stage 04

Feed Water Tank

Keeps a steady, controlled flow and pressure into the treatment line.

Stage 05

Carbon Filter

Activated carbon absorbs chlorine, odours and organic compounds that affect taste.

Stage 06

Multi-media Cartridge Filter

Fine cartridges capture remaining micro-particles and protect the RO membranes.

Core purification


Stage 07

UV Sterilization

Ultraviolet light inactivates bacteria and viruses before membrane treatment.

Stage 08

Reverse Osmosis

High-pressure membranes remove dissolved salts, heavy metals and other impurities.

Mineralisation & disinfection


Stage 09

Mineral Dosing

Measured amounts of essential minerals are added back for a balanced, fresh taste.

Stage 10

Product Water

Treated, mineralised water is held in a sanitised product-water tank.

Stage 11

Ozonation

Ozone disinfects the water and keeps it fresh, then naturally breaks down into oxygen.

Stage 12

UV Sterilization Before Filling

A final UV pass immediately before bottling as an extra layer of protection.

Control & bottling


Stage 13

Control Panel (PLC)

An automated control system monitors and runs every stage for consistent quality.

Stage 14

Automated Filling & Capping

Bottles are filled and sealed by machine, keeping handling to a minimum.

What's in every bottle


K + Mg

Added minerals

Reverse osmosis removes almost everything, including minerals. So we add potassium and magnesium back in measured amounts, for a fuller taste and to help your body keep its mineral balance.

pH 7.4

Balanced pH

pH is one of the clearest measures of water quality. Mineralisation brings SIZ to a balanced pH, which gives it its soft, smooth taste.
