About Us

Specialists in pre-cast concrete products since 1947.

Ri-Industries manufactures and supplies pre-cast concrete products. Since 1947 we have established a strong reputation for the quality of our products, service, and our knowledge, in particular, of septic tanks, waste water treatment and rainwater tanks. We are totally committed to achieving excellence in all that we do, which is why South Australian residents and businesses repeatedly buy our products and regularly recommend us.

For homeowners, our Ri-Treat waste water treatment system is considered to be the finest in Australia. The same goes for our concrete septic tanks and concrete rainwater tanks. If you want a product that is of the highest quality with trouble-free maintenance, then you want Ri Industries pre-cast concrete septic tanks, rainwater tanks and wastewater treatment systems.

Our wastewater treatment systems help you save water by recycling your waste water back to your garden and lawn.

For businesses, we offer Ri-Cycle, a commercial version of our waste water treatment system, trade waste arrestors, stormwater sumps, grates, frames and covers. We also work regularly with civil engineering and construction companies to provide tailored pre-cast concrete solutions such as retaining wall panels, bridge parapets, pre-cast beams and arch tunnels. If you have a special project needing pre-cast concrete, we can provide the solution.

Committed to excellence

From our base in Angle Park, South Australia, we have made it our life’s work to deliver outstanding pre-cast concrete products. We are committed to excellence, not only in our manufacturing techniques and processes but through every interaction we have with our customers.

We are South-Australian owned and operated and we service all parts of metropolitan Adelaide, rural and regional areas within SA and the Northern Territory.

Ri-Industries was the first South Australian company to combine the manufacture, delivery and placement of septic tanks. With engineering experience that spans over 60 years, we have developed a number of associated products to deal with sewage and waste, most notably our Ri-Treat system. Our unique design has become a leader in South Australia for the management and treatment of waste water.

All of our products are ‘over-engineered’. That is how we strive for 100% excellence. Plumbers describe our products as “second-to-none” and “the best in South Australia”. We are proud of our stand-out quality of product and service. This is further backed up by our on-time deliveries, knowledgeable sales team, after sales back-up services and a manufacturers warranty.
