900 litre Flat D-Shaped Baffled Water Tank
Product Overview
The 900 Litre Flat D-Shaped Baffled Water Tank is a robust and high-capacity solution for the storage and transportation of potable water and a wide range of other compatible liquids.
Manufactured from durable MDPE / polyethylene, this flat D-shaped tank provides a nominal capacity of 900 litres, equivalent to approximately 238 imperial gallons. Its low-profile design makes it particularly suitable for vehicle-based and mobile applications where a substantial volume of water needs to be stored while keeping the overall tank height practical.
The tank incorporates an integrated baffling system, with grooves and openings passing through the tank to help disrupt the movement of water. These internal baffles reduce water sloshing from side to side during transportation, making the tank particularly suitable for mobile applications such as professional window cleaning, car valeting and vehicle cleaning.
The natural version is manufactured from translucent medium-density polyethylene, allowing the approximate water level to be viewed through the tank. This provides a convenient way to monitor the remaining water supply without having to open the tank.
The tank is supplied with a large 16" vented lid and a standard 1" BSP female outlet, providing convenient access for filling, inspection and connection to compatible taps, hoses, pumps and other equipment.
The tank has dimensions of approximately 810 × 1500 × 810 mm and an empty weight of approximately 43 kg. The baffle design reduces the maximum usable capacity to approximately 840 litres.

Flat D-Shaped Design
The 900 Litre Flat D-Shaped Baffled Water Tank has been designed to provide a large volume of water storage while maintaining a practical, low-profile configuration.
With dimensions of approximately 810 × 1500 × 810 mm, the tank provides substantial storage capacity while making efficient use of available floor space.
The D-shaped configuration makes the tank particularly suitable for vehicle-based applications and other installations where a flat, stable tank design is preferred.
It can be used for a wide range of applications, including:
- Professional window cleaning
- Car valeting
- Mobile vehicle cleaning
- Mobile pressure washing
- Commercial cleaning
- Potable water storage
- Agricultural applications
- Horticultural applications
- Irrigation
- Vehicle-based water systems
- Temporary water storage
- General-purpose liquid storage
The available installation space should be checked carefully before ordering, including sufficient clearance around and above the tank for access to the lid, outlet and associated equipment.
Integrated Baffle System
The tank incorporates an integrated internal baffling system designed specifically to reduce water movement during transportation.
The baffles are formed by grooves and openings that pass through the tank. These interrupt the movement of water and help prevent large volumes of liquid from moving rapidly from one side of the tank to the other.
This makes the tank particularly well suited to mobile applications where water needs to be transported in a vehicle.
The baffling is particularly beneficial for:
- Window cleaning
- Car valeting
- Mobile vehicle cleaning
- Commercial cleaning
- Mobile pressure washing
- Vehicle-mounted water systems
- Water transportation
Reducing liquid movement can help improve stability during transportation, particularly when accelerating, braking and cornering.
The baffles do not eliminate water movement completely, and the tank must still be properly secured before transportation.
The internal baffle design reduces the available storage capacity, giving the tank a maximum capacity of approximately 840 litres despite its nominal 900 litre classification.
Ideal for Window Cleaning
The 900 litre capacity makes this tank particularly suitable for professional window cleaning businesses requiring a substantial mobile water supply.
Its flat D-shaped configuration provides a large storage capacity while maintaining a practical overall profile.
The integrated baffle system helps reduce water movement while the tank is being transported, making it suitable for vehicle-based window cleaning systems when correctly installed and secured.
The natural translucent construction also allows the approximate water level to be monitored, making it easier to determine when the tank requires refilling.
The 1" BSP outlet can be connected to suitable pumps, hoses and other window cleaning equipment using compatible fittings.
Ideal for Car Valeting
The tank is also particularly well suited to professional car valeting and mobile vehicle cleaning applications.
A large water reserve allows operators to work away from a fixed mains water supply, while the baffled construction helps reduce water movement during transportation.
The 900 litre capacity provides enough water for demanding commercial applications, although the maximum usable capacity of the baffled tank is approximately 840 litres.
Optional taps, hose connections, float valves and other accessories are available to configure the tank for different cleaning requirements.
Applications
The 900 Litre Flat D-Shaped Baffled Water Tank is particularly suited to high-capacity mobile and above-ground water storage.
Typical uses include:
- Professional window cleaning
- Car valeting
- Mobile vehicle cleaning
- Mobile pressure washing
- Commercial cleaning
- Potable water storage
- Agricultural water storage
- Horticultural applications
- Irrigation systems
- Vehicle-based water systems
- Temporary water storage
- General-purpose liquid storage
The combination of a large storage capacity, flat D-shaped design and integrated baffles makes this tank particularly useful for transporting water in mobile cleaning applications.
