A Great Alternative to Fibreglass Septic Tanks

Whilst you can be reassured as to the robustness and effectiveness of our tanks, you don’t need to worry about installation. Turley Bros will make the installation process easy and will install on site.

EPA Code of Practice & Certification

Turley Bros are proud to announce that our Tank conforms to the current Standards of Environmental Practice as per the EPA Code of Practice and has achieved European EN 12566-1 certification.

Meeting all the definitions and mandatory standards of a septic tank in the European Union, our EN12566-1 certified Turley septic tank has a capacity of 3,400 litres. That’s enough to solve the sewage disposal problem of an eight person home.

Perfect Septic Tank Solution:

The high strength concrete tank design makes it free from seepage, leaking, and intrusion risks commonly caused by roots from the vegetation in the vicinity and the acidity of the sewage.


The Turley Septic Tank, with its two chamber design and access covers, ten millimetre steel loops for handling, ventilation access, bitumen seal and pipe seal facilities at the inlet and outlet ends, is an ideal choice for not only new installations, but also is the tank of choice for replacement or upgrading of an existing tank.
