About ANARROSI Engineering
ANARROSI Engineering is a UK wastewater engineering consultancy focused on one thing: getting equipment and plant back to dependable service, and keeping it there.

How we think
Four principles we work by.
Practical first
Advice has to work on a wet Tuesday morning with the team you have, not just on paper.
Evidence before spend
We find out why equipment fails before recommending money is spent on it.
Plain reporting
Findings written for operators, managers and budget holders alike.
Built to last
We hand over routines and records so improvements outlive our time on site.

Why I’m building ANARROSI Engineering
I’m Samuel Egbejinmi. My background spans mechanical fabrication in Nigeria and wastewater plant operations and maintenance in the UK. Through my business, E&S Mechanical Fabrication, I developed a practical approach to equipment problems. I look at how the equipment is built, how it operates, what has failed and whether repair, refurbishment or replacement makes the most sense.
Working in wastewater has shown me how much depends on what happens after a fault is fixed. An operator may notice the first signs of a problem, a maintenance team may carry out the repair, and the next shift may inherit the same issue without knowing what was found. When those details are lost, it becomes harder to recognise repeat failures or decide where to invest in improvements.
That’s why I’m building ANARROSI Engineering. My aim is to help wastewater teams recover equipment performance, investigate recurring failures and turn those findings into practical maintenance and improvement plans. The work I want to offer brings together equipment condition assessment, repair and refurbishment planning, asset management, and plant operations consultancy.
I’ve also developed a site management platform to support that work. An operator can scan an asset tag and report a fault with a photo. Maintenance can pick it up as a work order and record what was done. That information stays with the asset, so the next shift can see what happened and the team can spot patterns over time.
I want clients to come away with clear answers to three questions: what can we recover, what should we change, and how will we know whether the change worked? That’s the kind of engineering support I’m building ANARROSI to provide.
