What Rain Harvesting does

Rain Harvesting, founded in 1989 and headquartered in Milton, Queensland, Australia, designs and manufactures specialty hardware for residential, commercial, and agricultural rainwater collection systems. The company operates as Rain Harvesting Pty Ltd. under the broader Blue Mountain Co (BMCo) parent brand, alongside Gutter Mesh and Plumbing product divisions. Its product portfolio centers on a '12 Steps of Rain Harvesting' methodology developed over 25+ years and comprises rain heads (Leaf Eater, Leaf Beater, Leaf Catcha sub-brands), Maelstrom super-fine filtration systems, downpipe and rain barrel diverters, first flush diverters, tank screens and solar shields, post-tank final-stage filters, tank level gauges, sediment management components, charged line management valves, and ancillary plumbing fittings. Technical differentiators include angled mesh screens for leaf shedding, mosquito-proof mesh under 1mm, vortex-based Maelstrom filtration, and proprietary first-flush diversion mechanisms designed to isolate contaminated initial roof runoff.

The company distributes products globally through eight localized regional e-commerce websites (Australia, USA, New Zealand, Europe, South Africa, India, UK, and Rest of World) with multi-language support, supplemented by iOS and Android mobile apps, a marketplace sign-in portal, and presumably trade/retail channels for hardware. Revenue is generated primarily through hardware sales of physical components, with pricing varying by region and quote-based for larger commercial configurations. Go-to-market is sales-led with content marketing support: a free 'Designed by Rain Harvesting' system design service converts consultative engagement into hardware sales, while a content ecosystem including the 12 Steps Masterclass, interactive selection calculators (Mass Balance, First Flush, Filter Selector), the Rain Harvesting Handbook, and the Water Balance community initiative drives top-of-funnel awareness and SEO. Customer segments are split horizontally, with residential homeowners as the primary segment and commercial buildings, schools, and agricultural properties as a secondary segment. The business model is asset-light specialty hardware distribution with a content and community moat layered on top of the physical product catalog.

Products and services

• Rain Heads Leaf and debris filtration devices installed on downpipes that keep mosquitoes and pests out and prevent contamination from entering the rainwater system. Includes the Leaf Eater product family (Stream Original, Stream Shield, Advanced, Original, Plus, Slimline, Ultra), the mid-size Leaf Beater range for tight spaces, and bucket-style Leaf Catcha rain heads (Slimfit, Rectangular, Round) for maximum water capture.
• Maelstrom Range Super-fine filtration and super-high water catchment system using advanced vortex technology to deliver massive quantities of clean rainwater directly to the tank.
• Downpipe and Rain Barrel Diverters Devices that capture and redirect water from downpipes to gardens, pools, or storage tanks, including the Clean Rain Ultra and Clean Rain Advanced all-in-one downpipe solutions that filter leaves and divert first flush from catchment areas.
• Tank Screens and Solar Shields Fine mesh screens (under 1mm) for tank inlets that block contaminants while allowing water entry, with solar shields and covers that block sunlight to prevent algae growth and protect stored water quality.
• First Flush Diverters Devices that automatically divert the initial contaminated roof runoff away from the storage tank, including Carrot-style diverters (20L/40L capacity), chamber-based systems with electronic valves, and the commercial-grade Delta series for large properties.
• Pipe Screens, Tank Overflows and Vent Cowls Components including Mozzie Stoppa mosquito-proof pipe screens, tank overflow kits, flap valves, vent cowls, and air gaps that manage tank overflow and keep the tank breathing while preventing pest entry.
• Final Stage Filtration (Post-Tank Filters) Filters and cartridges that treat water at the final stage before use, reducing sediment, color, and odor to make rainwater ready for household applications.
• Tank Level Gauges Monitoring devices that track water levels in storage tanks, ranging from basic analogue gauges to smart gauges that connect to mobile devices for real-time level monitoring and trend analysis.
• Tank Outlets Fittings for connecting storage tanks to various outlet options, enabling proper water extraction and system connectivity.
• Gutter Outlets and Downpipe Flow Fixtures including gutter outlets and Easy Tee junctions that connect gutters and downpipes to manage rainwater flow throughout the harvesting system.
• Sediment Management Products designed to manage sediment, silt, and dirt accumulation in tanks to maintain rainwater cleanliness and system efficiency.
• Charged Line Management Components including sliding gate valves that drain pipes and manage wet systems to keep water at high quality and prevent stagnation.
• Rain Harvesting App Mobile application available on iOS App Store and Google Play that helps users manage and monitor their rain harvesting systems, including real-time tank level monitoring and trend analysis.
