Ireland’s Wastewater Treatment Specialists

We have been at the forefront of the wastewater treatment for more than two decades and provide a range of products and services to suit both the domestic and commercial markets. Our larger systems have won numerous awards because they provide a much higher level of treatment than those provided by other suppliers of wastewater systems. While most systems need to be desludged every 12 months, our systems only need to be desludged every seven to ten years making them much more cost effective over their lifetime. All our products are designed, installed and maintained by our qualified engineers and carry a 30 year guarantee for your total peace of mind. Call us now on 1890 929 612.
