800 Litre Flat Baffled Water Tank
Product Overview
The 800 Litre Flat Baffled Water Tank is a robust, 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 low-profile flat tank provides a substantial 800 litre storage capacity, equivalent to approximately 175 imperial gallons. Its broad, flat design makes it particularly useful for applications where a large volume of water is required while maintaining a relatively low overall height.
The tank incorporates an integrated baffling system designed to strengthen and support the tank structure when full, while also helping to reduce the movement of water during transportation. This makes it particularly suitable for mobile applications such as window cleaning, car valeting, vehicle cleaning and other situations where liquids need to be transported in a vehicle.
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 1" BSP outlet and an 8" lid, with optional accessories available to configure the tank for different applications.
With dimensions of approximately 1250 × 1095 × 700 mm and an empty weight of approximately 52 kg, the tank provides a useful combination of capacity, durability and practical low-profile storage

Low-Profile Flat Design
The 800 Litre Flat Baffled Water Tank has been designed to provide substantial water storage while maintaining a practical overall height.
Measuring approximately 1250 × 1095 × 700 mm, the tank provides 800 litres of storage in a broad, low-profile configuration.
This design makes it particularly suitable for vehicle-based applications, trailers, mobile cleaning equipment and other installations where available height may be restricted.
The flat configuration also provides a large base area, helping the tank make efficient use of available floor space.
The tank 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 internal baffling system that performs two important functions.
Firstly, the baffles help strengthen and support the tank structure when it is filled with water.
Secondly, the internal structure helps disrupt the movement of water when the tank is transported.
Reducing liquid movement can be particularly beneficial in mobile applications, where water can otherwise move significantly during acceleration, braking and cornering.
The baffled design makes this tank particularly suitable for:
- Window cleaning
- Car valeting
- Vehicle cleaning
- Mobile pressure washing
- Commercial cleaning
- Vehicle-mounted water systems
- General liquid transportation
The baffles help reduce water movement but do not eliminate it completely. The tank must therefore still be installed and securely restrained by a suitably qualified person before transportation.
Ideal for Window Cleaning
The 800 litre capacity makes this tank particularly suitable for professional window cleaning businesses requiring a substantial mobile water supply.
Its low-profile design can make efficient use of available vehicle or trailer space, while the internal baffles help reduce water movement during transportation.
The translucent natural construction also allows the approximate water level to be monitored, making it easier to determine when the tank needs refilling.
The standard 1" BSP outlet provides a convenient connection point for suitable pumps, hoses and other window cleaning equipment.
Ideal for Car Valeting
The tank is also well suited to professional car valeting and mobile vehicle cleaning applications.
An 800 litre water reserve provides a substantial supply for mobile cleaning operations, allowing work to be carried out away from a fixed mains water connection.
The baffled construction helps reduce water movement while the tank is being transported, making it particularly useful for vehicle-based cleaning systems.
Optional tap kits, hosetail kits and other accessories allow the tank to be configured around the requirements of the individual application.
Applications
The 800 Litre Flat Baffled Water Tank is suitable for a wide range of commercial, agricultural and mobile water storage applications.
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
- Water transportation
- General-purpose liquid storage
The combination of a large capacity, low-profile design and integrated baffles makes this tank particularly suitable for mobile applications where water needs to be transported.
