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 tanks have won numerous awards because they provide a much better treatment than those provided by other providers of wastewater systems. While most systems need to be desludged every 12 months, our systems only need to be emptied 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.
