Creating Generational Assets Since 1972 Products

On-site Stormwater Detention,
Retention & Stormwater Harvesting

On-site stormwater detention (OSD) helps slow the movement of water that flows off impervious surfaces in our urban landscape. Retention and stormwater harvesting solutions can help to sustainable store water for re-use. Applications include residential, industrial, and commercial developments to meet flood mitigation and water quantity objectives.

A locally manufactured range of modular precast OSD Tanks, the AtlanVault is fully trafficable with quick installation and easy maintenance.

They are available in varied configurations to suit your project footprints and on-site requirements – with flexible heights, layouts, and dual-stacked designs.


The Atlan MegaVault is an industry-leading approach to medium to large detention requirements.

A modular precast concrete tanks that is designed using fundamental principles of cost-effective and efficient detention – the MegaVault offers greater depth capability, condensed site footprint & superior structural outcomes.


An open-chambered HDPE water quantity solution for detention, retention, and re-use.

The AtlanChamber system can meet design requirements for large capacity configurations, infiltrative surface area, and confined subsurface footprints – and provide stormwater harvesting capabilities.


A Fibre-reinforced Polymer (FRP) tank system for water storage, detention, and retention, the TankStor is light, easy to handle, and quickly installed.

With excellent corrosion and rust resistance, these devices have a 50-year design life – with varied applications from stormwater attenuation to harvesting & re-use scenarios.


Pipe & Conveyance

Seamlessly meet the demands of your site and environment with our range of SN8 and ADS pipe and conveyance products, all built for tough conditions.

A dual wall pipe engineered from high-density polyethylene.


Engineered for resiliency and sustainability, AtlanFlow ADS Pipe is a great project asset that provides high performance and adaptability when it comes to stormwater conveyance.


Junction Pits are versatile solutions for pipe connection, maintenance access points, and the redirection of stormwater flows.


Green Infrastructure & Bioretention

Green infrastructure (GI) has become an important part of urban planning, water sensitive urban design (WSUD) and future-proofing our cities.

These developments help our communities build environmental sustainability and resilience – and provide improved water quality outcomes, increased green space, and flood mitigation.

FlowFilter is a decentralised stormwater treatment system that can be inserted into grated drains. Quick & easy installation, these SQIDEP approved devices ensure surface level treatment on-site – and capture gross pollutants, nutrients, and sediment.


Floating Wetlands are green stormwater assets embedded with plants. Their root systems provide biological and chemical stormwater treatment processes, which improve local water quality by removing nutrients, sequestering pollutants, and preventing algae blooms.


A water sensitive urban design (WSUD) solution, AtlanBio is our engineered bioretention, stormwater filtration and growing media. AtlanBio is formulated to meet hydraulic specifications and key industry standards, including MRTS Form G.


Hydrocarbon Capture

Hydrocarbon contamination is a risk on many sites, including service stations, car parks, train infrastructure, industrial areas and transformer yards.

Oil & water separators are designed to ensure the capture of hydrocarbons, which helps these sites meet environmental and sustainability criteria.

The Atlan Spillceptor is a full retention separator for high-risk application. With guaranteed hydrocarbon capture in all flow and spill conditions, it provides reductions in light liquid loads to 5mg/litre or less, and easy maintenance.


Designed for versatility, the Flowceptor provides hydrocarbon capture capabilities with secondary treatment capabilities for removing sediment, suspended solids, hydrocarbons and nutrients.


Combining the capabilities of the Flowceptor & Spillceptor, the Triceptor treats on-site requirements for both low and high-risk catchments. This includes hydrocarbon capture, high-flow bypass, and water quality objectives.


Gross Pollutant Trap

A gross pollutant trap (GPT) is a stormwater treatment system’s first line of defence. Providing primary treatment, GPTs remove bulky pollutants, plastic pollution, sediment, and litter – and stop their conveyance from our catchments.

StormSack is a filter pit system, installed directly into stormwater systems to capture contaminants close to the surface – including organic matter, sediment and litter.


Utilising a special vortex cleaning action, the Atlan Ecoceptor is a versatile fibreglass GPT system with sediment,  silt, total suspended solids, and light liquid capture capabilities for low-risk sites and scalability for large catchments.


BaffleBoxes contain a series of sediment settling chambers, to allow the separation of sediment and gross pollutants. These devices are often accompanied by public observation covers, providing community education opportunities.


A non-blocking hydrodynamic separator, the Vortceptor uses unique low vortex conditions for high-performance pollution removal and excellent water quality outcomes. Key features include innovative single-piece fibreglass design and 100-year design life.


Tertiary Stormwater Treatment

Tertiary stormwater treatment provides enhanced filtration and ‘polishing’ of stormwater – including nutrient and heavy metal removal. These systems are often combined with other treatment devices, and detention infrastructure, to ensure water is fit for discharge.

A filter cartridge system that uses siphonic flow and maximised treatment area to ensure water quality and removal of pollutants. A low maintenance system that suits many on-site configurations and detention scenarios.


StormSack is a filter pit system, installed directly into stormwater systems to capture contaminants close to the surface – including organic matter, sediment and litter.


Designed to meet confined footprints and water sensitive urban design requirements, the FlowFilter is a specialist stormwater filtration system. Lightweight, easy to install, with minimum on-site lifting requirements.


A modular bioretention system, AtlanBasin is SQIDEP approved and provides high pollutant reduction in a small footprint. These sustainable assets can be used in place of standard catch basin structures, rain gardens, bioretention cells and media filters.
