The combined 8000kg weight of the tank and lid means it will not float or shift in saturated ground — a critical advantage in Ireland’s wet climate. Plastic tanks weighing a fraction of this require expensive anchoring systems. This 11000 litre precast concrete tank stays exactly where you put it.
Manufactured from minimum 50N steel-reinforced precast concrete with 115mm wall thickness, this tank can support vehicle and machinery loading above ground. Buried underground, it becomes part of the site infrastructure — lasting 50 years or more with no maintenance required.
This tank is manufactured to comply with EN 12566-1 and is approved by Uisce Éireann — meaning it meets the highest Irish and European standards for wastewater treatment infrastructure. Fully compliant with EPA water quality requirements.
Murphy Precast provides crane-equipped transport to deliver and place the tank directly into your pre-prepared excavation. After a 50mm sand bed is laid, the tank is lowered into position in a single lift. No concrete backfilling typically needed — saving significant time and labour costs on site.
