900 litre Flat D-Shaped Water Tank
Product Overview
The 900 Litre Flat D-Shaped Water Tank is a robust and versatile solution for the storage of potable water, non-potable water and a wide range of other compatible liquids.
Manufactured from durable MDPE / polyethylene, this large-capacity D-shaped tank provides 900 litres of nominal storage, equivalent to approximately 238 imperial gallons. Its flat D-shaped design provides a practical and space-efficient solution for above-ground water storage and is particularly well suited to applications where a large volume of water is required.
Unlike the baffled version of this tank, this model is non-baffled. This provides the full nominal 900 litre capacity and makes it suitable for static water storage applications where internal liquid movement during transportation is not a primary consideration.
The tank is manufactured from natural translucent medium-density polyethylene, allowing the approximate water level to be viewed through the tank wall. This provides a convenient way to monitor the remaining contents without having to remove the lid.
The tank is supplied with a large 16" vented lid and can be configured with a range of outlet options, making it suitable for different water storage, cleaning, agricultural and commercial applications.
With dimensions of approximately 810 × 1500 × 810 mm and an empty weight of approximately 43 kg, the tank provides substantial storage capacity while maintaining a practical flat profile

Flat D-Shaped Design
The 900 Litre Flat D-Shaped Water Tank has been designed to provide a substantial volume of water storage while maintaining a practical overall profile.
Measuring approximately 810 × 1500 × 810 mm, the tank provides 900 litres of nominal storage without requiring the taller configuration of an upright tank.
The D-shaped construction makes efficient use of available floor space and provides a practical solution for above-ground installations.
The tank is suitable for a wide range of applications, including:
- Potable water storage
- Non-potable water storage
- Agricultural applications
- Horticultural applications
- Irrigation
- Commercial water storage
- General-purpose liquid storage
- Temporary water storage
- Cleaning applications
- Vehicle-based water systems where suitable restraint is provided
The available installation space should be checked carefully before ordering, including sufficient clearance around and above the tank for access to the lid and fittings.
Non-Baffled Construction
This 900 litre model is a non-baffled water tank.
Unlike baffled tanks, there are no internal baffles designed to restrict the movement of liquid within the tank. This allows the tank to provide its full nominal 900 litre capacity.
The non-baffled design is particularly appropriate for static or semi-static installations where the tank is not routinely transported while full.
Potential applications include:
- Static water storage
- Agricultural water storage
- Horticultural applications
- Irrigation systems
- Commercial premises
- General-purpose water storage
- Temporary water storage
- Potable water storage
If the tank is intended to be transported while containing water, the absence of internal baffling should be taken into consideration. The tank and its supporting structure must be appropriately secured, and the effects of liquid movement must be accounted for.
For regular transportation of large volumes of water, a suitable baffled tank may be more appropriate.
Applications
The 900 Litre Flat D-Shaped Water Tank is suitable for a wide range of above-ground water storage applications.
Typical uses include:
- Potable water storage
- Non-potable water storage
- Agricultural water storage
- Horticultural applications
- Irrigation systems
- Commercial water storage
- Cleaning applications
- Temporary water storage
- General-purpose liquid storage
- Industrial and site applications
The large 900 litre capacity makes the tank particularly suitable for applications where a substantial volume of water needs to be available without requiring a larger 1000 litre tank.

Overseas orders

A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
