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

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.

After nearly 80 years of manufacturing precast concrete products in South Australia, we've learned that successful projects begin long before a tank arrives on site.

From understanding site conditions and planning for installation to maintaining quality throughout the manufacturing process, every stage contributes to long-term performance.

In our latest article, we share a few lessons we've learned over nearly eight decades of supplying precast concrete solutions for residential, commercial, agricultural, and civil infrastructure projects.

Australia's engineering workforce shortage isn't just an industry issue, it's affecting infrastructure delivery across the country.

Engineers Australia recently highlighted the ongoing shortage of experienced engineers and the pressure this is placing on infrastructure projects: https://www.engineersaustralia.org.au/news-and-media/2026/07/engineering-shortages-continue-hold-back-local-infrastructure-delivery



At Ri-Industries, we help reduce project risk by delivering engineered precast concrete solutions backed by reliable documentation, consistent quality and predictable delivery. When engineering resources are stretched, dependable manufacturing partners become even more valuable.

Not all precast concrete tanks are created equal. The right solution depends on far more than just capacity.

Before a tank is specified, factors such as ground conditions, expected loads, traffic above the installation, environmental exposure, and the intended application all need to be considered. Getting these details right helps ensure the asset performs reliably for decades. Planning a project? Talk to our team early to ensure your precast concrete solution is designed for the conditions and performance your project demands.

Recent rainfall across South Australia was a welcome reminder of just how valuable every drop of water can be.

While heavy rain can be disruptive, it also presents an opportunity to capture and store water for the drier months ahead. A quality rainwater tank allows homeowners, farms and businesses to make the most of nature's supply whether it's watering gardens, irrigating landscapes, washing vehicles or providing water for other non-potable uses.

Harvesting rainwater isn't just about reducing water bills. It's about building resilience, making better use of a valuable resource, and being prepared for the next dry spell. At Ri-Industries, we manufacture durable precast concrete rainwater tanks designed to provide reliable water storage for decades to come.

As communities grow, so does the challenge of managing stormwater. Roads, rooftops, parking lots, and other hard surfaces prevent rainwater from soaking into the ground. Instead, runoff moves quickly across developed areas, carrying pollutants into local waterways and increasing pressure on drainage systems.

That's why stormwater management is becoming an increasingly important part of community planning. Solutions such as rainwater storage tanks, detention systems, and other water management infrastructure help capture, store, and manage runoff before it becomes a problem

Underground infrastructure is becoming one of the most important tools in modern urban planning. As cities grow and available land becomes more limited, planners are increasingly moving critical systems below the surface, from stormwater management and water storage to utilities and civil infrastructure, allowing communities to function efficiently without sacrificing valuable space above ground. The growing reliance on underground infrastructure highlights the important role manufacturers such as Ri-Industries play in delivering the infrastructure needed to support future growth.

Recent infrastructure reports have highlighted climate-resilient water and wastewater systems as a national priority, recognising the increasing demand placed on essential services as populations grow and environmental conditions evolve.

From residential developments to regional projects, wastewater and water storage solutions play an important role in supporting sustainable growth and helping communities manage resources effectively.

At Ri-Industries, we manufacture precast concrete wastewater tanks and rainwater tanks designed to meet the needs of developers, contractors and communities across Australia. As demand for resilient infrastructure continues to grow, practical solutions at ground level remain an important part of the bigger picture.
