There are concrete tanks and then there are 5500 litre precast concrete tanks built by Murphy Precast. At 5250kg of factory-cast concrete, this unit does not move, does not float, does not degrade, and does not need replacing in ten years. Every chamber, every seal, every measurement has been designed at our Enniscorthy facility and drawn to engineering standard — because that is what large-site wastewater treatment demands.
Three chambers means three stages of primary treatment before any liquid leaves the tank. Chamber 1 handles the initial solids settlement. Chamber 2 continues anaerobic breakdown. Chamber 3 provides a final clarification stage. The result is significantly cleaner effluent entering your percolation area — protecting it and extending its working life.
The twin wall plastic risers bring the access points up to ground level — making inspection and de-sludging straightforward for your registered contractor. The concrete lid provides a robust, durable cover that handles loading from ground traffic above. No compromise on the finish.
Irish winters saturate the ground. Plastic tanks float. At 5250kg, this precast concrete tank does not. Its mass combined with factory-quality construction means it withstands heavy soil pressure, harsh ground conditions, and the full range of Irish weather — for 50 years or more with minimal maintenance.
Delivered from our Enniscorthy factory ready-to-install with integrated lifting points. Your groundworks team prepares the excavation — the tank goes in by crane in a single move. No on-site forming, no pouring, no curing delays. Fast programme. Clean site.

A 5500 litre precast tank is specified when a standard 2000 or 3500 litre unit simply does not have the headroom for the site’s wastewater load. The most common customers include:
| Customer Type | Why a 5500 Litre Tank Is Needed |
|---|---|
| Large rural homes and family dwellings | Higher occupancy generates more daily wastewater — the 5500 litre capacity and 3-chamber treatment provides the headroom and treatment quality needed. |
| Agricultural buildings and farm sites | Farm facilities, worker amenities, and ancillary agricultural buildings off mains drainage need robust, compliant on-site treatment. |
| Rural commercial and hospitality premises | B&Bs, holiday lets, small hotels, and rural businesses with variable and higher wastewater flows benefit from the larger capacity and three-stage treatment. |
| Replacement of older undersized systems | Upgrading from a failing or undersized tank? Going to 5500 litres and three chambers future-proofs the installation and reduces servicing frequency. |

Every Murphy Precast septic tank is manufactured in accordance with EPA guidelines and Irish Building Regulations — the legal framework that governs new-build planning applications and replacement wastewater systems in Ireland. Specifying a compliant tank at the planning stage removes a significant risk from your project.
All domestic wastewater systems in Ireland must also be registered with your local authority. Registration is completed online via
protectourwater.ie
— one-off €50 fee, required within 90 days of commissioning. Failure to register is an offence with a fine of up to €5000.
The
Environmental Protection Agency (EPA)
oversees the National Inspection Plan for domestic wastewater treatment systems in Ireland. Local authorities carry out inspections — using a compliant, factory-made Murphy Precast tank means your system is in the best possible position when an inspector calls.
