Tell us about your site

The Bio-Crete system is a popular choice among homeowners, architects, and builders. The starting price is €3,348.02 +VAT.  It’s a simple, quick-to-install concrete tank that offers reliable and environmentally sustainable groundwater protection. Certified by PIA in Aachen, Germany to EN 12566, Bio-Crete is a testament to our commitment to quality and sustainability.


Septic tanks generally are a very cost effective and low maintenance way to treat domestic wastewater if you have the right soil and underground conditions. Prices start from €792.95 +VAT. If your site layout is such that you can get a gravity flow to and from the tank you will eliminate the need for more expensive infrastructure, such as connecting to main sewer lines, pumps or treatment plants.

Septic Tanks

Our standard Septic Tank, designed for up to 8 people, is an effective, low-maintenance solution for domestic wastewater treatment, especially in areas with suitable soil and underground conditions. Certified to EN12566-1, our septic tanks are ideal for sites with good natural percolation rates. Manufactured in our Clonroche factory, these tanks use self-compacting concrete certified to I.S. EN 206-1:2002.


We use our on site laboratory to achieve the required level of performance, quality, and regulatory compliance.

Upgrading your Septic Tank

There are many reasons to upgrade your existing septic tank for example it may be allowing the flow of effluent into your ground water. County councils are increasingly stepping up their activity in inspections of septic tanks. They often find below standard water quality in streams and trace upstream to any potential source. They may also get called out to inspect one house in an area and inspect every house on that road.

As always, we will offer advice on upgrading and grants.

How water treatment works

The aim of both septic tanks and treatment plants is to get your effluent to the required level before it reaches ground water. Septic tanks and the primary chamber of treatment plants facilitate the natural process of wastewater treatment by separating solid waste from liquids, allowing bacteria and other microorganisms to break down and decompose the organic matter. Treatment plants have additional stages of waste treatment, in particular, growing cultures of aerobic bacteria which are highly efficient at effluent digestion.


After being treated, the liquid portion of your wastewater will leave your tank and pass through your percolation area. There it will receive further treatment in the soil using naturally occurring bacteria before eventually reaching ground water.

What you need to know for Installation

Our wastewater tanks are delivered by our trucks & cranes from our factory in Clonroche directly to your site. Our experienced lorry drivers are happy to help advise your digger driver to ensure your tank matches up with your pipework and is level in the excavation.

We are more than happy to talk you through the installation process over the phone.

Percolation Area Guide

Depending on the results of your soil test and site suitability report, a variety of different percolation types could be used. We can provide Coco filters, or 32mm pipe work for soil and sand polishing filters.

We are always on hand for advice and to talk your installer or digger driver through the process.
