Rainwater Tanks # water tank suppliers
Safe, Strong & Easy Access
Our tanks are equipped with a lockable, three-stainless-bolt access cover featuring:
- A watertight seal
- Lightweight design (only 9.5kg)
- 600mm clear opening for easy access and maintenance
- Load tested to 1.5 tonnes
Adjustable turret heights allow for optimal inlet depth and safe installation in light traffic areas.
Smarter Water Harvesting – No Charged Downpipes
We use a variable turret height system to position your tank for maximum fall. This eliminates the need for charged downpipes, reduces pipe sediment build-up, and ensures every drop of rain is efficiently collected.
Out of Sight, Out of Mind
Our tanks are installed flush with the ground, making them perfect for placement under driveways, gardens, or other outdoor spaces — completely hidden, yet highly functional.
Clean & Protected Overflow System
Each tank includes a full-flow flap valve on the overflow outlet. This:
- Prevents contaminated backflow
- Blocks vermin
- Does not restrict water overflow
Built to Last
Our tanks are wet-cast individually from 40MPa steel fibre reinforced concrete and comply with AS1546.1 standards — ensuring exceptional strength and durability.
Cleaner Water, By Design
A 1mm stainless steel mosquito-proof leaf filter ensures only clean water enters the tank. Plus, our construction bypass keeps debris out during site work and is removed when construction is complete.
Anti-Floatation for Peace of Mind
Our 10,000L tanks include retention concrete to prevent tank flotation — saving time, hassle, and installation costs.
Medium And Large Size Water Tanks Available
Medium or large size water tanks available
We have 6,100 litre medium size water tanks or 10,000 litre large water tanks. Suitable for above or below ground water storage. Our 10,000 later water tank has the capacity to harvest large volumes of rainwater, maximising rainwater harvesting for extended supply in long dry periods.The medium tank is suitable for a wide range of geographical profiles and provides a good balance between size and capacity. This is our most popular and economical tank.
