Floating Wetlands for environmentally sustainable stormwater management

We design and construct Floating Treatment Wetlands for stormwater treatment

Stormwater treatment that’s cost effective

One of the most useful things about our floating Treatment Wetlands is how you can install it into existing forebays and in bioretention ponds. So keep your existing facility while improving the treatment capacity – and without taking on any significant costs or overheads.

No additional land resource required: Floating Treatment Media can be retrofitted to your existing asset.

More about floating treatment media

Stormwater carries pollutants like suspended solids, heavy metals and petroleum hydrocarbons. If untreated, these pollutants flow into our waterways and harbours.

Floating Treatment Media leverages what already happens in nature. We construct a base for plants to grow. The plant roots grow through the water column and biofilm forms providing an ideal home for pollutant-digesting microbes and bacteria. When a storm comes, water flows through the roots and the suspended solids, like clay, are captured; the microbes and bacteria then get busy consuming and sequestering the pollutants.

Floating Treatment Wetlands:

You can use it in any water environment requiring treatment, and it has a remarkably high effect on:

Can be retrofitted to existing water bodies

Operate in fluctuating water levels

Require minimal maintenance

DO NOT “plug up”

Operate on a smaller footprint to all other tertiary treatment devices
