As 2025 draws to a close, we’d like to extend our heartfelt thanks to all our customers, partners and suppliers — your trust and collaboration have made this year a great success.
We will be closed from Friday 19 December 2025 and will return on Monday 5 January 2026.
From All of Us at Australian Tanks — Thank You!
With 2025 wrapping up with a fully booked December, this is your opportunity to place your orders now to ensure your projects land in our January and February production schedule.
Whether you need small/medium capacity OSD tanks or a large-volume solution like the Parthenon system — talk to us before the Christmas close to lock in your spot.
We look forward to working with you in 2026.
Warm regards,
The Australian Tanks Team
Engineering Smarter Infrastructure — OSD Solutions That Work
At Australian Tanks, we’re proud to deliver high-quality, precast stormwater detention systems tailored for today’s fast-paced construction environment. Our solutions include small-to-large on-site detention (OSD) systems, modular underground concrete tanks, and heavy-duty, trafficable infrastructure designed to meet the demands of commercial and civil projects.
Why Choose Our Pre-cast OSD Systems?
Cost-effective & Lifecycle-efficient — Our modular tanks compete favourably against traditional block-and-slab solutions, delivering long-term value through lower maintenance, easier access, and durable construction.
Quick, On-Time Installation — Systems arrive pre-cured, fully equipped (weir walls, filtration, manholes, orifice plates, etc.), ready for immediate installation — often allowing for connection and backfilling on the same day.
Traffic-Ready & Heavy Duty — Built to Australian standards our tanks support heavy-vehicle traffic (e.g., 4-axle twin steer trucks), making them ideal beneath commercial infrastructure, car parks, roadways or high-traffic zones.
Modular & Scalable — From small 7,000L or 12,000L systems to large-capacity solutions (e.g. the Parthenon Onsite Detention System for 150,000L up to multi-million-litre requirements), we can meet a wide range of project scales.
Our OSD solutions give developers and engineers confidence — combining structural integrity, compliance, and efficiency to support tight project timeframes while saving valuable construction time and reducing on-site disruption.
Contact us today at Australian Tanks on 1300 282 657 to learn how our heavy-duty concrete tanks can be configured to meet your exact capacity and performance requirements — and delivered on time, every time.
