The question
A stew prompted me to think more deeply about the water I was using.
The person behind the systems
Hello, I’m Mark.
I build water filters, not websites. I started The Water Mark because I wanted to understand what was really in the water I used every day.
My work is personal: I design, fit and explain each system around the water profile and the needs of the people who’ll use it.

The first question
It started over a pot of stew.
In 2008, while cooking a stew, I asked myself a simple question: what’s the most unhealthy ingredient in this meal? That moment began a long fascination with water and its place in everyday life.
I began to question the water I was using to cook and to look more closely at the filters available. I wanted an approach that went beyond a generic cartridge and took the actual water profile seriously.
In 2021, my water filtration work reached a wider audience when I appeared on Channel 4’s Come Dine With Me. My “Superfood Stew” was a joint winner, sharing the prize. The experience helped bring my water work into view, but the real focus stayed the same: better water, explained clearly.

From a kitchen question to postcode perfect.

A closer study
I received expert tutoring in the fundamentals of water treatment and filtration.

Out in the field
I engineered the Portable Well for events, then brought that practical experience back to home water.

Better than Bottled
Version 3.0 and postcode perfect design put local water profiles at the centre of the system.
How I work
Engineering you can understand.
I design systems around local water profiles, real demand and established component standards. For larger requirements, the design can scale around contact time and volume.
Our approach to restructuring is grounded in verifiable molecular exchange, crystalline chemistry and fluid dynamics, not claims based on unmeasurable resonance.
I’ll personally explain the system and what each stage is intended to do, so you can make a considered decision about your water.

Whether you’re exploring a home system, water restructuring or an event solution, I’ll help you understand the options.
