The RapidPlas 4,000L Slimline Tank is the perfect middle ground between medium and large storage. It’s big enough to make a serious dent in water bills and secure supply for the garden or household, while still slim enough to fit comfortably along fences or side yards. Australian-made and built to last, it’s a popular choice for families.
When you need serious storage but don’t want a bulky round tank, the RapidPlas 5,000L Slimline Tank is the answer. Offering excellent capacity for household water security, gardens, or pool top-ups, it’s the largest in our standard slimline range while still fitting into suburban backyards.
The RapidPlas 500L Slimline Tank is compact, durable, and perfect for homes with limited space. It tucks neatly against a wall or fence, giving you reliable water storage for gardens, car washing, or small household use. Made in Australia from food-grade, UV-stabilised polyethylene, it’s built tough for local conditions.
