As stormwater flows over impervious surfaces in our urban catchments, it conveys a variety of pollutants. Stormwater harvesting programs allow us to remove these pollutants, utilise stormwater runoff as a sustainable water supply, and protect our waterways.
Common stormwater pollutants include gross pollution, microplastics, heavy metals, nutrients (total nitrogen and total phosphorus), garden chemicals, pet waste, light liquids from traffic, litter and debris. Treatment allows their removal in our urban catchments and mitigates their negative impacts on water quality.
Stormwater treatment devices provide capabilities to capture pollution from incoming stormwater – which improves the quality of harvested stormwater and prevents the conveyance of these contaminants into storage tanks.
By pretreating stormwater flows, sediment and debris are prevented from entering stormwater tanks, which lowers the maintenance requirements for tank chambers and improves the service life of stormwater harvesting systems. Treatment devices ensure harvested stormwater is fit for reuse applications – and protect operational assets such as sprinklers, pipes, hoses and plumbing.
Atlan Stormwater provides a full range of primary, secondary and tertiary treatment devices to meet stormwater quality objectives across stormwater harvesting projects.
These assets provide better water-sensitive urban design (WSUD) outcomes, improve safety, mitigate health and environmental risks, reduce maintenance requirements, and prevent the spread of pollution.
