Water Treatment Specialist
Stefan Massingham

Stefan Massingham, water treatment specialist and founder of Invicta Water Treatment.

Invicta Water Treatment is run, day to day, by Stefan Massingham MSc, a water chemist who has spent his whole career understanding what comes out of the ground, and what it takes to make it safe.

Stefan graduated from the University of Birmingham in 1993 with a degree in chemistry, and has worked in the water industry ever since, across sewage treatment, offshore platforms and private supplies. Every water problem that reaches Invicta is reviewed by him personally.

Water treatment, and the legislation that surrounds it, can seem highly technical and confusing. Our job is to make it simple: we take care of the science and the compliance, so you are left with a supply you can trust and never have to think about.

Three steps. No shortcuts.

Every supply and system we take on follows the same considered process, because every source needs to be understood before it can be treated.

Understand your source

We start with a site survey and a UKAS-accredited water analysis. Nothing gets specified before we know exactly what we are dealing with.

Design the system

We design the filtration, storage and treatment to match your source and your property's demand. Everything specified is chosen for reliability and long service life.

Install and maintain

Our own engineers install every system. Once you're up and running, we service it on a schedule, and answer emergency calls the same day.
