Septic Tanks
Durable pre-cast concrete septic tanks designed for residential and commercial properties. Our tanks meet Australian standards for wastewater management, offering reliable, low-maintenance solutions. Ideal for non-sewered areas, they ensure safe waste treatment and environmental compliance.
Wastewater Treatment Systems
Advanced aerobic wastewater treatment systems including Ri-Treat EP10 and EP33 models. These systems recycle greywater for garden use, complying with AS/NZS 1546.3:2017 standards. Suitable for homes and buildings with 5-33 occupants, ensuring efficient water reuse.

Underground concrete rainwater tanks for residential and commercial water conservation. Designed for durability in South Australian conditions, these tanks provide reliable storage for irrigation and non-potable water needs, reducing mains water dependency.
Trade Waste Arrestors
Specialised trade waste management systems for commercial and industrial sites. These arrestors capture contaminants from wastewater streams, ensuring compliance with environmental regulations and protecting sewer infrastructure from harmful discharges.
