Engineer-Designed Septic Tanks

Ri-Industries has over 60 years experience in the septic tank business and have developed efficient manufacturing techniques to produce septic tanks of the highest quality that are built to last.

If you are building a house or simply replacing an old septic tank, then consider buying your septic tank from Ri-Industries.  Our septic tanks tanks offer a number of benefits:

• All septic tanks tanks are engineer-designed and built from fine tolerance steel moulds which produce reliable wall thickness
• Tanks are made from 40 MPa concrete to give additional strength and durability
• Internally, all joints are sealed, reducing the potential for leakages
• Tanks are offered in 14 different sizes, for maximum flexibility for use in your property
• Child-proof and vandal-proof lids on our septic tanks give you additional peace of mind

Ri-Industries is a one-stop shop for all your septic tank requirements and we have many additional items that are required to be installed with your tank, such as saddle risers, poly trench, distribution chambers and geo fabric.

In locations where the delivery of concrete septic tank saddle risers/lids is difficult due to space or other limitations, we offer lightweight glass reinforced concrete as an alternative. See specifications for more details. If you would like a septic tank which allows you to recycle your waste water, then you need our unique Ri-Treat waste water treatment system.
