Enduramaxx 500 Litre Rainwater Harvesting Tank (110 Gallon) 1725051-RH
Product Overview
The Enduramaxx 500 Litre Rainwater Tank is a compact above-ground storage tank designed for collecting and storing rainwater around domestic, garden, agricultural and commercial properties. With a 500-litre capacity and slimline vertical design, it provides a practical way to add rainwater storage without requiring a large amount of ground space.
Manufactured from MDPE, the tank is designed for non-potable water storage and can be used as part of a rainwater harvesting system. Its modular format also allows multiple tanks to be interconnected, making it possible to increase storage capacity as requirements change.

Compact Rainwater Storage
With a capacity of 500 litres, this Enduramaxx rainwater tank is suited to applications where additional water storage is required but available space is limited.
The vertical format gives the tank a relatively small footprint, with a diameter of just 700 mm. This makes it easier to accommodate alongside buildings, in gardens, around agricultural properties or in other areas where a wider tank would take up more space.
The tank can collect rainwater for suitable non-potable applications, helping make use of water that would otherwise run directly into drainage systems.
Modular Rainwater Harvesting System
A key feature of the 500 Litre Rainwater Tank is its modular design. Multiple compatible tanks can be interconnected to create a larger overall storage system.
This can be useful where water storage requirements may increase over time. Rather than replacing a smaller tank with a much larger vessel, additional tanks can be incorporated into the system where site conditions and the installation allow.
For larger rainwater harvesting projects, the modular approach can provide greater flexibility when planning the available storage capacity.
Rainwater Harvesting Applications
The 500-litre tank can be incorporated into a range of non-potable rainwater storage systems.
Typical applications include:
- Garden rainwater collection
- Garden irrigation
- Horticultural water storage
- Domestic rainwater harvesting
- Greenhouse watering
- Agricultural rainwater collection
- Commercial non-potable water storage
- General outdoor water use
The stored water should only be used for suitable non-potable purposes and must not be used for drinking or food preparation.
