Atlan BaffleBox

Atlan BaffleBox is a precast concrete GPT (Gross Pollutant Trap) containing a series of sediment settling chambers separated by baffles.

The primary function of the Atlan BaffleBox is to remove sediment, suspended particles, and associated pollutants from stormwater. Atlan BaffleBoxes may also contain trash screens or skimmers to capture larger materials, trash, and floatables.

The Atlan BaffleBox has proven effective in removing sediment from storm water runoff. It is mainly utilised in areas where sediment control is a primary concern, while other storm water Best Management Practices (BMPs) may be more effective in areas where additional storm water pollutants, such as dissolved nutrients, oil and grease, or metals, are prevalent.

Features & Benefits

Advanced Pollutant Capture

Separates and retains gross pollutants, sediment, and floatables to improve water quality.

Efficient Sediment Management

Designed with internal baffles and sediment zones to maximise pollutant retention and minimise resuspension.

Minimal Head Loss

Innovative floating weir design maintains only 350mm of head loss, even when the screen is fully blocked.

Handles Multiple Inflows

Accommodates diverse site configurations with the ability to manage multiple inflows seamlessly.

Durable Construction

Built with high-strength, long-lasting precast concrete or fibreglass designed to withstand harsh environmental conditions and heavy-duty applications.

Low Maintenance Requirements

Accessible design simplifies cleaning and maintenance, reducing operational costs.

BAFFLEBOX

Modular and Customisable Design

Configurable to specific new and retrofit site requirements, accommodating various flow rates and pollutant loads. Prefabricated components ensure quick and cost-effective installation with minimal disruption.

Atlan View Observation Cover

Designed to accommodate community stormwater education opportunities.

Enhanced Safety Features

Designed to prevent hazardous pollutant overflow during heavy rain events, protecting downstream ecosystems.

Manufactured in Australia

Locally fabricated in our Australian precast concrete production facilities to meet ISO9001 Quality Standards.
