Today we know over 50% of oxygen is produced by the ocean (NOAA) to support life in the ocean and on land. We also know that over 30% of the ocean is dead (UNEP) not producing oxygen or food, only 50% is producing krill (FAO) the second step in the marine food chain and with over 30% dead the ocean normally a 26% carbon sink (IPCC) is now adding into ‘climate change’ effects.

Toxic / Harmful Algal Blooms have now taken over the worlds urban and agricultural waterways with the neurotoxin BMAA now considered deadly to pets, biodiversity and now humans as triggers for Dementia, Parkinson’s, Alzheimer’s and MND.

Why, we contaminate every drop of rainfall in the urban and agricultural environments, discharge the wastewater of 7 billion humans into the ocean (over 80% untreated) and we have cut down half of earth’s natural carbon sequestration mechanism, 5 trillion trees.

Due to the intrinsic limitations of current ‘traditional and screen’ filtration we find ourselves in this global, natural water contamination disaster driven by population and industrialization, an inverse relationship.

The first task, invent the only ‘high flow to fine particle capture filtration technology’ we have named ARI material (high flow to fine particle capture filtration) which has been proven infield and scientifically to process just over 3000 litres per minute (3080), per square metre capturing particulates to 63µm (microns).

CSIRO, ChemCentre (NATA) and Curtin University have carried out all data with our joint industry PhD winning the coveted Chancellors Award for Science and Engineering.

The SFD captures 95% of the physical waste and filters the water just inside the drain opening prior to infrastructure contamination.

Due to the sheer volume of vegetative and other waste that enters the unprotected infrastructure we have engaged with the waste management industry to carry out the ongoing servicing falling in line with residential and commercial waste management. The waste we capture valuable for agriculture.

By capturing the waste and filtering the water prior to drain and system contamination we can protect our waterways and ocean whilst minimizing flash flooding and mosquito habitat all using the existing stormwater infrastructure.

With nearly 1 billion drains installed around the world we can now engage rainfall as a water source to replenish groundwater reserves and protect wetlands, estuaries, mangroves and manmade water treatment systems such as WSUD, living streams, swales transforming the infrastructure into a valuable asset.
