Look Inside the Book

Every page has one big drawing and a box with the rules and numbers you need to know:

The welfare unit has two sides: dirty for boots and PPE, clean for washing and eating.

These are real pages from the book. The table of contents is the full one: 8 parts and 59 topics.

The Problem Isn't You. It's How It Was Explained to You.

You're filling a bowser from a standpipe and the end of the hose is lying in the water at the bottom of the excavation. The supervisor looks at it, then at you: what's the risk?

You know it's wrong. But the word won't come. The leaflet explains backflow and back-siphonage in long paragraphs, with fluid categories one to five and no picture of where the water actually goes.

Backflow = upstream flow. Sewage is Fluid Category 5: keep hose ends out of dirty water.

In the book, backflow is one page. An arrow shows the dirty water running the wrong way, back up the hose and into the main. The box says it plainly: sewage is Fluid Category 5, keep hose ends out of dirty water.

The same goes for the clean and dirty zones in the welfare, capping open ends, pipe storage, chlorination in mg/l and who to report to: each one has its own page.

You see why the rule exists, and you do it right on site without going back to the leaflet. On the test, the question reads like a job you've already done.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The leaflet: line after line of text
  • Trench hygiene explained only in words
  • You walk into the test with doubts
Excavations in which pipework for the conveyance of water intended for human consumption is to be laid shall be maintained in a condition such that the ingress of contaminants into the pipe bore is prevented at all times. Pipes and fittings shall not be placed in direct contact with the trench floor or with standing water, and all open ends shall be sealed by means of appropriate caps whenever work is not in progress. Excavated material shall be positioned at a sufficient distance from the trench edge to prevent its migration into the excavation.
FOR THIS
  • A clean trench in one drawing
  • The rules in one box
  • You see it and you get it
Right vs wrong trench: pipe off the ground, ends capped, spoil kept back.

One Page, One Topic, All Clear

Think of it this way:

You're on a new main with the gang: 100 mm, 200 metres, ready to charge. How much water is in there, and how much chlorine takes it to 20 mg/l?

In the book you open the volume page and the pipe is drawn cut open: 100 mm inside, about 7.85 litres per metre, 200 metres ≈ 1,570 litres. Turn the page and the worked example takes you to grams of chlorine, one step at a time.

1,570 l at 20 mg/l = 31.4 g chlorine ≈ 314 ml of 10% hypochlorite (study example).

Same with the clean and dirty zones in the welfare, pipe stored off the ground, capping open ends, backflow and flushing the main: each one on its own page.

Water Hygiene Illustrated is 8 parts and 59 topics, all drawn, and at the end a test-day revision part with the whole day in 9 steps and the numbers to have to hand.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've done this job for years and haven't sat a written test since school?

Yes. It isn't a beginner's book: it follows the job you already do, with short sentences, large print and one drawing per topic.

Where does the content come from?

It's written for the UK National Water Hygiene card (the EUSR 'Blue Card'), not a generic hygiene course. The content comes from current EUSR scheme information, Water UK's Principles of Water Supply Hygiene, the drinking water quality regulations and DWI guidance. Always check the details of your course with your trainer.

Is it official material?

No. It's an independent study guide, not affiliated with or endorsed by EUSR, Energy & Utility Skills or any water company.

Does it replace the course?

No. It doesn't give you a card or a certificate: the Blue Card only comes from passing the approved National Water Hygiene course and test. The book helps you prepare and revise. For health questions, follow your employer's occupational health advice.

Are the practice questions the ones on the test?

No. They're written for this book, in the same multiple-choice style, with a short explanation of each answer.

When and how does it arrive?

As a PDF by email, to the address you enter at checkout. The two free books come the same way.

Do I have to pay every month?

No. It's a one-off payment.

Can I have it on paper?

Yes. Print it at home or at a print shop and keep it in the van.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
