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 pro

ducts 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 with the garden and lawn irrigation system that is included. 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 extended warranties.

What happens before installation is just as important as what happens on-site. Before precast infrastructure is delivered, there’s engineering, manufacturing, curing, quality control, logistics planning, and coordination happening behind the scenes.
Most people only see the final install, but reliability starts long before products leave the yard.

Concrete infrastructure doesn’t get installed in perfect conditions. Projects move forward through mud, rain, tight access points, shifting ground, changing schedules, and weather that doesn’t always cooperate.

That’s why durability matters long before the final install. Precast concrete infrastructure needs to handle real-world site conditions, not just ideal ones on paper. Because once the ground is closed back over, reliability becomes a whole lot more important than appearances.

Our underground concrete tanks are manufactured locally in South Australia using reinforced, high-frequency vibrated concrete designed for long-term performance where it counts most: below the surface.

Most people don’t think much about underground infrastructure once it’s installed, but site conditions, ground movement, drainage, and long-term performance all matter long after construction wraps up.

That’s why proper design, manufacturing, and installation matter from the beginning. Our precast concrete products are manufactured locally in South Australia and built to suit real project requirements, not one-size-fits-all solutions.

There’s a lot of building happening across South Australia right now. New developments, upgrades, projects kicking off everywhere. Most people see what’s going up. We focus on what’s going underneath.

That’s the part that doesn’t get much attention, but it’s what everything else relies on. Drainage, storage, structural components… if that’s not right, it shows up later.

We manufacture precast concrete products used across a range of infrastructure projects, not just tanks, but the stuff behind the scenes that keeps things working the way they should.

It’s not the visible part of a job, but it’s one of the most important.

If you are in the market for an Aerobic Wastewater Treatment system but you dont have the room for our Ri Treat EP10, or you may have a difficult site for access we still have you covered.

The FujiClean Australia - Wastewater Treatment Systems Ace 1200 has been expertly engineered using leading Japanese technology to deliver exceptional performance while minimising environmental impact. Thanks to its lightweight and space-saving design, the FujiClean ACE system is easy to transport and simple to install, making it a practical solution for a wide range of applications.

The ACE1200 is designed to receive and treat all household wastewater—including from toilets, bathrooms, laundry, and the kitchen. It delivers advanced effluent treatment through a multi-stage process that incorporates both anaerobic and aerobic digestion. Naturally occurring microbes break down waste across three chambers, while nitrogen levels are significantly reduced through internal recirculation and microbial consumption.

We have the Fuji Clean Ace 1200 tanks in stock and ready to go from our Wingfield yard.
