Stormwater360

What Stormwater360 does

Stormwater360 is a New Zealand-based specialist distributor and engineering services provider focused on stormwater treatment, founded in 1996 by Mike Hannah and headquartered in Auckland. The company supplies a portfolio of proprietary and internationally-licensed treatment technologies spanning five categories: green infrastructure (Filterra® and Filterra® Bioscape® biofiltration, LiveRoof® modular green roofs, Grasscrete™ permeable pavement), filtration (Jellyfish® membrane filters, StormFilter™ media filters, EnviroPod® and LittaTrap™ catchpit inserts), hydrodynamic separators and gross pollutant traps (VortCapture™, Vortechs™, Cascade Separator™), retention and detention (ChamberMaxx™), and diversion and oil/water separation (Fox™ Valves, ESK™). It acts as the primary New Zealand channel for several international brands and holds registered trademarks across the product range.

The business operates a sales-led go-to-market with expert consultation, supported by a free online sizing tool (design.stormwater360.co.nz) that funnels engineers, developers, councils, and industrial operators into the sales process. Customers include local government bodies (Hastings District Council, Department of Conservation), industrial operators (Humes Pipeline Systems), commercial developers (Covington Group's Station Bay, Wild and Love Early Learning), and engineering consultancies (Tonkin + Taylor, ACH Consulting, Downer) across New Zealand cities from Auckland and Hamilton to Christchurch and the West Coast. Revenue is generated through three streams: hardware product sales (Filterra®, StormFilter™, etc.), design and consulting services, and recurring operations and maintenance via the SWCMP Certified Maintenance Provider program.

Operationally, Stormwater360 employs a small specialist team (firmographic range 11–50) led by technical founder Mike Hannah (27 years tenure, first Stormwater Life Member of Water New Zealand), with senior engineers, regional sales leads, a marketing function, and a Group Financial Controller appointed in 2024 to support scaling. The company is actively expanding into Australia and abroad under dedicated business-development leadership and continues to broaden its product portfolio through partnerships (Contech Engineered Solutions, Fox Environmental Systems, University of Canterbury, Pattle Delamore Partners) and ongoing technical publication output from 2003 to 2024.

Products and services

• Filterra® Market leading biofiltration system with a small footprint, designed for high infiltration (2540mm/hr) and removal of contaminants including nutrients and metals. Approximately 1/10th the size of a traditional rain garden. For councils, developers, and engineers.
• Filterra® Bioscape® Scaled, high infiltration and performance biofiltration system with a compact footprint up to 90% smaller than traditional rain gardens. Features controlled media composition ensuring consistent removal of TSS, nutrients, metals, and hydrocarbons. For urban densification, infill developments, and constrained sites.
• LiveRoof® Green Roof System Pre-vegetated modular green roof system combining international technology with locally designed media. Trays are pre-vegetated and can absorb up to 70% of annual rainfall through evapotranspiration. For sustainable building design and stormwater mitigation on commercial and government buildings.
• Grasscrete™ Permeable Pavement 150mm thick reinforced concrete slab poured in situ with voids filled with grass. The concrete bears vehicle weight while allowing stormwater infiltration through the grass-covered voids. For carparks, driveways, and load-bearing surfaces.
• ChamberMaxx™ Retention, detention or underground reuse tank system for managing stormwater volumes and peak flows. For developers, councils, and commercial sites requiring stormwater volume control.
• Jellyfish® Filter Next generation membrane filter for stormwater treatment offering lightweight, cost-effective performance. For sites requiring fine sediment and contaminant removal in a compact format.
• StormFilter™ Media filter utilizing perlite cartridges in a vault configuration. Stated as the most utilized media filter in the world. Achieves minimum 75% TSS removal before discharge. For industrial and commercial stormwater treatment trains.
• EnviroPod® Filter Cost-effective, easily maintained catch pit insert for removal of litter and gross pollutants from stormwater runoff. For councils and developers requiring source-control gross pollutant removal.
• LittaTrap™ Catchpit Insert

Expansion highlights5 records

Broad incumbents

• Oldcastle Infrastructure: Oldcastle Infrastructure (CRH) is a large diversified civil infrastructure supplier offering stormwater management products (catch basins, vaults, separators, treatment systems) alongside a much broader precast and drainage portfolio. It competes on stormwater treatment but as one of many categories.
• Advanced Drainage Systems (ADS): ADS is a US-listed leader in stormwater and drainage solutions with stormwater chambers (StormTech), retention/detention, and treatment products. It competes with Stormwater360's ChamberMaxx and broader conveyance/detention offering in civil infrastructure projects.
• NDS: NDS is a broad drainage and stormwater management solutions provider (channels, drains, retention/detention, filters). It is a wider-portfolio incumbent competing with Stormwater360 on commercial and residential stormwater management, particularly FlowTech-style green infrastructure products.

Direct peers

• StormTrap: StormTrap is a specialty manufacturer of modular stormwater detention and retention systems (direct equivalent to ChamberMaxx) plus water quality products. It targets the same developers, councils, and civil engineers for underground volume management on commercial and residential projects.
• Imbrium Systems: Imbrium Systems designs and supplies hydrodynamic separators, filtration devices, and oil/water separators (e.g., downstream equivalent of ESK and LittaTrap products). Its product portfolio overlaps directly with Stormwater360's separators, GPTs, and inserts segments.
• Hydro International: Hydro International is a UK/US stormwater and wastewater treatment specialist offering hydrodynamic separators (similar to Vortechs, Cascade, VortCapture), filtration systems, and treatment trains. It competes head-to-head with Stormwater360 across municipal, industrial, and commercial developer customers seeking pre-engineered stormwater quality solutions.
• Contech Engineered Solutions: Contech is a US-based global stormwater treatment leader that supplies many of Stormwater360's most important distributed product lines (Filterra, StormFilter, Vortechs, Cascade). Contech directly competes wherever Stormwater360 expands internationally and shares the same BMP, hydrodynamic separator, and biofiltration categories - making it both a partner and the principal competitor.
• Forterra (Bio Clean): Forterra's Bio Clean business supplies stormwater filtration systems and bioretention/media filters used in the same municipal and commercial settings where Stormwater360 deploys Filterra and StormFilter. It is a comparable distributor/integrator of BMPs serving engineering specifiers.

Emerging players

• Jensen Stormwater Systems: Jensen Stormwater Systems manufactures filtration and treatment devices (media filters, oil/water separators, inserts) for municipal and industrial stormwater applications - direct product overlap with Stormwater360's filtration and separation portfolio at a smaller scale.
• Aqua Shield: Aqua Shield produces stormwater treatment products including filter media systems, inserts, and oil/water separators for carparks, subdivisions, and industrial sites - matching Stormwater360's catchpit insert (EnviroPod/LittaTrap/VortCapture) and oil/water separator (ESK) product categories.
