Bailey Slim Jim Water Tank 1000L - Premium Slimline Urban Water Storage
Maximize your property's water storage potential without sacrificing precious outdoor living space. The Bailey Slim Jim Water Tank 1000L is the ultimate high-performance, space-saving water storage solution designed specifically for modern New Zealand homes, tight urban footprints, and professional trade installations. Combining unparalleled structural strength with a sleek, contemporary aesthetic, this tank is engineered to meet strict NZ standards for rainwater harvesting and council-mandated stormwater management.
Why the Bailey Slim Jim is the Smart Choice for NZ Homeowners & Trade Professionals:
- Space-Saving Ultra-Slim Profile: At just 325mm wide, the Slim Jim is designed to fit seamlessly down narrow side-yards, pathway boundaries, and tight structural spaces where traditional round water tanks cannot go.
- Council-Compliant Stormwater Management: Engineered from conception as an easy, attractive solution for stormwater retention and detention. The flat ends allow for the simple, clean installation of inlets, overflows, and council-required orifices.
- 100% Safe Drinking Water: Manufactured in New Zealand using 100% virgin food-grade material. In civil emergencies or dry spells, your collected water remains completely safe for household drinking.
- Heavy-Duty Kiwi Durability: Features a unique patented design that provides unmatched wall strength and robust structural integrity compared to other slim tanks on the market.
- Architectural Style: Available in 11 fantastic contemporary colourways to perfectly match your home's roof, cladding, or NZ landscape style.
Versatile Integration & Easy Upgrades:
The Bailey Slim Jim is highly adaptable for residential water systems. Plumbers and trade installers can easily fit a submersible pump, allowing harvested rainwater to power outdoor garden taps, washing machines, and toilets. Pair your setup with a Rain Aid valve to ensure an uninterrupted water supply; if the tank runs low, the valve automatically tops it up from your mains water supply. To turn your tank into a beautiful living feature, an optional vertical garden kit can be easily attached to the required seismic restraint kit.
