Floating Treatment Wetlands (FTWs) come in a wide range of sizes and shapes – with traditional approaches incorporating islands of rectangular-shaped mats. However, innovations in customisable, modular approaches allow configurations in more complex shapes by using interlocking modules.
Utilising modular technology, the Atlan FTW system is composed of an HDPE float and a basket of growing media for effective plant establishment. Each module has an overall length, width, and height of 858mm x 858mm x 230mm, respectively.
The triangular shape of the Atlan FTW modules can be configured in organic shapes to meet footprint constraints or the aesthetic needs of the community.
Atlan FTWs can be anchored to the bank with earth anchors, or in deep water with large concrete blocks or plow anchors. This flexibility allows the Atlan FTW to rise and fall up to 2m in response to storm events.
Atlan’s Floating Treatment Wetlands is a modular system that can be installed in stages, allowing for budget constraints or progressive installation with development stages. As a modular system, it enables a range of different organic and geometric layouts. A key benefit of the Atlan Stormwater FTW system is the ability to start with a smaller installation and add additional modules as treatment, catchment, or developmental requirements change.
Large-scale green asset programs can be a costly investment for local councils. Pilot programs of smaller-sized installations can be used as ongoing trials to ensure that FTW solutions align with the requirements of local water bodies and improve water quality, amenity, and beautification.
Aided by the modular design of our Floating Treatment Wetlands, a successful pilot program can become part of a larger stormwater asset by adding modules to increase the area of the FTW.
The ability to add additional modules to an existing pilot program is of great benefit for councils wishing to test the waters – and allows the design of these assets to scale to meet their growing community needs as local support and water quality outcomes emerge.
