Reln

What Reln does

RELN Pty Ltd is a second-generation Australian-owned family manufacturer of plastic drainage and agricultural products, headquartered in Ingleburn, NSW, with operations since 1955. The company designs and manufactures four core product categories: surfacewater drainage (Storm Drain, Storm Mate, Storm Drain Pro, Uni-Pit Vortex, Civil Edge Pit, and channel/pit systems), groundwater drainage (Ag Pipe, Stretch Ag-Pipe, Soakwells, Splash Blocks), blackwater/wastewater solutions (Septic and Holding Tanks, Drain Trenching, Grease Traps, Pump Stations), and agricultural products (Feed and Water Tubs, Troughs, and Accessories). Its core technology is proprietary injection moulding manufacturing with machine capacities from 150T to 4000T, processing weights from 10 grams to 120kg, including pioneering recycled polymer technologies and the SP-1 Structural Foam Injection-Moulding Machine developed under an Australian Research and Development Board grant.

RELN operates a multi-brand portfolio under the RELN Group umbrella: RELN (core drainage), Aymroo (large bore plumbing fittings since 1982), AlphaTreat (wastewater treatment since 2005, formerly EcoWater), Tumbleweed (composters and worm farms), and FTR Products (Canadian distribution into North American big-box hardware stores). The company serves four primary customer segments: residential DIY homeowners (Drainage Solution Finder tool), plumbers and civil contractors (Professional/Content Hub), rural/remote properties (on-site wastewater solutions), and agricultural/livestock operations (feeding and watering equipment). Products are certified to multiple Australian Standards (AS3996, AS/NZS 1546.1, AS 2439-1:2007, S1547) and manufactured under ISO 9001:2015 quality management.

Revenue is generated primarily through hardware sales of proprietary drainage and agricultural products across domestic and export markets (20+ countries), distributed through a multi-channel network including retail/hardware stores, plumbing merchants, direct sales to civil contractors, and North American big-box retailers. The company also offers contract moulding services (industrial design, prototyping, tooling, production) as a secondary revenue stream. Pricing is set at retailer level rather than directly by RELN, with the company maintaining representation on Australian Standards Committees since 1987 to influence specification frameworks.
