Enduramaxx 26000 Litre Non-Potable Water Tank
Product Overview
The Enduramaxx 26,000 Litre Non-Potable Water Tank is a large-capacity above-ground storage tank designed for applications where substantial volumes of non-potable water need to be stored securely and efficiently.
Manufactured from durable Medium Density Polyethylene (MDPE), this vertical tank provides 26,000 litres of storage, equivalent to approximately 5,700 gallons. It is well suited to agricultural, commercial and domestic applications, as well as rainwater harvesting and sprayer tank use.
The tank is designed specifically for non-potable applications. It uses the same polymer as the WRAS-approved version, with the potable version distinguished by the inclusion of a suitable potable outlet.

Large-Capacity Non-Potable Water Storage
With 26,000 litres of available storage, this Enduramaxx tank is intended for sites that require a significant reserve of non-potable water.
Its substantial capacity makes it particularly useful for agricultural and commercial settings where water may be required for equipment, irrigation-related applications, spraying or other uses where potable water is not required.
The tank can also be incorporated into rainwater harvesting systems, allowing collected rainwater to be stored for later use.
Rainwater Harvesting & Sprayer Applications
The tank is specifically listed as suitable for rainwater harvesting and sprayer applications. Its large capacity makes it a practical option where smaller tanks would require frequent refilling or where a larger reserve needs to be maintained.
For rainwater harvesting systems, suitable filtration and associated equipment can be added depending on the requirements of the installation.
Access & Float Valve Installation
A large 620 mm screw lid provides convenient access to the inside of the tank for inspection, maintenance and cleaning.
The tank also features a dedicated upstand area for installing a float valve. Positioning the float valve in this area allows the available tank capacity to be used more effectively than installing a float valve through the side wall.
Applications
The Enduramaxx 26,000 litre non-potable tank can be used for a variety of large-scale water storage requirements, including:
- Rainwater harvesting
- Agricultural water storage
- Commercial water storage
- Sprayer tank applications
- Irrigation-related water storage
- Domestic non-potable water storage
- General above-ground water storage
