Designed for properties not connected to mains drainage, they safely process and treat wastewater before returning clean water to the environment.

Our range includes septic tanks, wastewater treatment systems, grease traps, low-pressure pipe networks for soil polishing, and tertiary filters using sand or coconut media for final purification.

Combining high treatment efficiency with low running costs, these systems provide dependable, cost-effective wastewater solutions that perform consistently for years to come.

Fully compliant with EPA and local county council regulations, all systems are quick and easy to install, even on sites with restricted space, limited budgets, or challenging ground conditions.

Built for long-term reliability, they offer sustainable wastewater management with minimal maintenance and maximum peace of mind.

Frequently Asked Questions

What size wastewater treatment system do I need?

System sizes are rated in PE (population equivalent). As a rule of thumb, choose the PE matching the number of bedrooms plus one — a typical 4-bed house suits a 6PE system. Our team can size your system exactly from your house plans or occupancy.

Do I need planning permission for a treatment system in Ireland?

New installations require planning permission, and your site will need a site suitability assessment carried out by a qualified assessor in line with EPA Code of Practice 2021. We can point you to the right steps for your county council.

What is the difference between gravity and pumped systems?

A gravity system discharges treated water by natural fall and suits sites that slope away from the tank. A pumped system uses an integrated pump to move treated water uphill or over distance to the discharge point.

How often does a treatment system need servicing?

Most systems should be serviced annually and desludged every 1 to 3 years depending on usage. Regular servicing keeps the system compliant and extends its lifespan.

Do you deliver nationwide?

Yes — we deliver across the Republic of Ireland. Delivery timelines and any site access requirements are confirmed when you order, and our team can advise on offloading for larger tanks.
