Water Tanks Engineered for Tasmania’s Demands
At Taztanks, we’re proud to offer Orion water tanks, a brand synonymous with quality, variety, and strength. Whether you're installing tanks in suburban backyards, tight-access courtyards, rural properties, or commercial and fire-safety settings, Orion has a solution tailored for you. Their extensive range includes UV-stabilised poly tanks, smart slimline models, galvanised steel, and fire- and septic-rated variants delivering flexibility without compromise .
All Orion poly water tanks are created from food-grade polyethylene, moulded in one sturdy piece to ensure excellent structural integrity and eliminate corrosion risk. Available in 22 COLOURBOND®-matching colours, they also enhance your landscape’s aesthetic appeal

Solutions to Match Every Site and Need
Round Poly Tanks
From compact 500 L units to large 26,000 L systems, these traditional-style tanks deliver easy access to clean, durable water storage. Their UV-resistant surface prevents algae growth and maintains water quality, while the one-piece construction ensures structural integrity under varied conditions .
Slimline Tanks
When space is limited, slimline tanks available in flat-wall, corrugated, or smooth-wall designs save room. They range from 600 L to 5,000 L and perfectly suit homes with narrow setups or hard-to-reach courtyards .
Galvanised and Aquaplate Steel Tanks
Orion’s steel options, whether classic galvanised or reinforced with AQUAPLATE®, provide a traditional aesthetic with modern durability. Available from 5,300 L to 27,500 L, these tanks withstand corrosion and demanding outdoor environments .
Specialty Tanks
Orion’s lineup also includes:
Septic tanks, single-chambered up to 4,500 L
