Atlan Stormwater is delighted to report our latest development in the US marketplace with the announcement of our distribution partnership with Jensen Infrastructure – serving stormwater management projects across Arizona, California, Hawaii, Nevada, Oregon, and Washington.
This agreement includes the exclusive distribution of our high-performance filtration solutions, AtlanFilter, FlowFilter, and FlowGuard, across these geographies.
A second-generation, family-run business, Jensen specializes in delivering infrastructure projects across the Western United States. The company provides comprehensive services across design, engineering, production, procurement, and logistics to meet project timelines and ensure timely installation.
Jensen provides custom-engineered solutions to meet the challenges of critical infrastructure projects. It works closely with local, state, and federal agencies to ensure regulatory demands, supporting the development of a sustainable, compliant stormwater network.
Atlan Stormwater and Jensen Infrastructure share common goals of servicing the project needs of engineers, contractors, agencies, and municipalities with seamless stormwater project management and effective, efficient, and performance-driven stormwater assets.
We believe clean waterways are a right, not a privilege. Together with Jensen, we will serve local communities and deliver our range of filtration devices to remove pollutants in urban catchments – ensuring Joy in Water for future generations.

Stormwater Pollution Removal: Advanced Filtration Solutions
Throughout this partnership, we look forward to deploying our tertiary filtration range on stormwater projects across America to protect our shared watersheds, lakes, and seas.
Atlan’s Joy in Water philosophy is reflected in our expanding tertiary filtration device assessments. These include our TAPE designated range (AtlanFilter: CULD & PULD, FlowFilter: CULD), and latest verification for AtlanFilter through the New Jersey Department of Environmental Protection’s NJCAT program.
AtlanFilter
AtlanFilter
AtlanFilter is a filtration cartridge system designed for installation in OSD tanks, filter bays, and water quantity infrastructure, which utilises an up-flow treatment process to maximise treatment surface area for high-performance pollution removal.
In 2025, AtlanFilter demonstrated valid performance claims and joined the list of Washington State Department of Ecology’s designated technologies for the following treatment categories – CULD: Basic (Total Suspended Solids, Phosphorus, and PULD: Dissolved Metals (Copper & Zinc). This has been followed by NJCAT verification in 2026.
FlowFilter
FlowFilter
Featuring concrete or fibreglass housing, FlowFilter is a specialist water quality device with a reduced footprint for constrained sites.
Housing filtration cartridges in a range of configurations and flow rates, the FlowFilter is versatile and easily adapted for new developments or retrofit projects. These devices provide effective tertiary treatment for meeting your project’s water quality requirements.
In 2025, FlowFilter received TAPE designation through the Washington State Department of Ecology TAPE program (Technology Assessment Protocol – Ecology), America’s leading protocol for validating stormwater device performance. It received Conditional Use Level Designation (CULD) for basic treatment (Total Suspended Solids) and Phosphorus treatment.
FlowGuard
FlowGuard
A compact system for surface-level deployment in strip drains and pits, FlowGuard offers a decentralized approach to tertiary filtration. Providing at-source stormwater treatment, these devices are ideal for sites with limited space and stormwater catchments with localised runoff, such as carparks, roof outlets, and driveways.
FlowGuard filters pollutants such as hydrocarbons, heavy metals, total phosphorus (TP), and total nitrogen (TN), ensuring safe disposal during routine maintenance. With easy site-level access, these devices are easy to maintain, resulting in lower operational costs throughout the asset’s lifespan.
