Look Inside the Book

Every page has one large drawing and a box with the measurements, intervals and checks you need to know:

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

You're on the phone to a desludging contractor and he asks how often your tank needs emptying. You don't have an answer.

You looked it up. The guidance covers it in long paragraphs: tank capacity, population equivalent, sludge build-up, exceptions. By the third paragraph you've lost the thread.

2.5 m³ tank: 2 people every 5 years, 4 people every 2, 5+ every year

In the book, that same question is one page: a 2.5 m³ tank drawn with the household beside it. 2 people every 5 years, 4 people every 2, 5 or more every year.

Every other topic has its own page too: the three layers inside the tank, the percolation trench, the symptom chart, the inspector's six checks and the year-round checklist.

You see it, you understand it, and you book the desludging yourself, without going back to the guidance.

The Same Topic, Two Ways to Learn It

THIS
  • The guidance: line after line
  • Trenches and gravel explained only in words
  • You meet the inspector still unsure
Percolation trenches are to be constructed in accordance with the site assessment and the design hydraulic loading, with the distribution pipework laid at a uniform gradient so as to ensure the even application of effluent along the full length of each trench. The trench width, the depth of aggregate beneath and around the perforated pipe, and the minimum thickness of unsaturated subsoil below the trench invert should each be determined with reference to the percolation test results and to seasonal variations in the water table.

  • The widths, depths and fall in a box

One Page, One Topic, All Clear

Think of it this way:

It's a wet week in November and there's a soft, extra-green strip across the lawn, right where you think the pipes run. You need to know now: is it normal, or is it a call to make?

You open the book at the symptom chart and there it is, drawn: each warning sign, its possible cause and who to call, from smells and gurgling pipes to wet ground and a ditch.

Smell, slow drains, gurgling, wet ground, green strip, ditch: possible cause and who to call

The same goes for the three layers in the tank, the percolation trench, desludging by household size and the inspector's checks: each one on its own page.

Septic Tank Illustrated is 9 parts and 65 topics, all drawn, and at the end a year-round checklist, the most frequent mistakes and a ten-question quick review.

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

Frequently Asked Questions

Is it for me if I've never had a septic tank before?

Yes. It's written for homeowners in the Republic of Ireland, not for professionals: Irish homes, Irish soils and Irish rules, every idea drawn and no jargon. Northern Ireland has its own rules, so this book isn't written for NI.

Where does the content come from?

From the EPA Code of Practice for domestic waste water treatment systems (2021), the Water Services Acts 2007 and 2012 and Part H of the Building Regulations, checked against the current versions. The EPA and your council publish this information for free, in long documents. The book puts it in drawings, one topic per page, in the order you need it at home: the symptom chart, desludging by household size, the inspector's checks and a year-round checklist.

Is it official material?

No. It's an independent illustrated guide. It is not published, approved or endorsed by the EPA, any local authority or any government body.

Does it replace a registered contractor or a site assessment?

No. It helps you understand and look after your system. Repairs, desludging and site assessments are always for a registered contractor or a qualified professional.

Are the picture cases the ones the inspector uses?

No. The 30 picture cases are written for this book to help you recognise warning signs. They are not official inspection questions.

When and how does it arrive?

The book and the 2 bonus books arrive as PDFs by email, at the address you enter at checkout.

Do I have to pay every month?

No. It's a one-off payment, with no subscription.

Can I have it on paper?

Yes. The PDF is printable, so you can keep it in the folder with the house papers.

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.

Before You Close This Page

No more rereading guidance that doesn't stick.
