500 Litre Water Tank, Flat, Baffled
Product Overview
The 500 Litre Flat Baffled Water Tank is a robust and practical solution for the storage and transportation of potable water and other compatible liquids.
Manufactured from durable HDPE / polyethylene, this low-profile rectangular tank is designed for applications where a substantial water storage capacity is required while maintaining a practical overall height.
The integrated baffle system helps reduce water movement within the tank during transportation, making it particularly suitable for mobile applications such as window cleaning, car valeting, vehicle cleaning and mobile pressure washing.
The natural translucent finish allows the water level to be viewed through the tank, providing a convenient way to monitor the remaining contents.
With a 500 litre nominal capacity and an empty weight of approximately 35 kg, the tank provides a useful combination of high-capacity water storage, durability and stability for mobile and above-ground applications.

Low-Profile & High-Capacity Design
With dimensions of approximately 920 × 1000 × 620 mm, the 500 Litre Flat Baffled Water Tank provides substantial water storage capacity while maintaining a practical flat design.
The low-profile configuration makes the tank particularly useful for vehicle-based applications, trailers and mobile equipment, where available space may be restricted.
At approximately 35 kg when empty, the tank can be positioned and installed before filling. Once filled, suitable mechanical handling and lifting arrangements should be considered due to the substantial weight of the water.
Integrated Baffle System
The tank incorporates an internal baffle system designed to reduce the movement of water during transportation.
The baffles are formed through the tank and help disrupt the movement of liquid, reducing water sloshing when the tank is transported with water inside.
Water tanks can be extremely hazardous when transporting large volumes of liquids. Please make sure that they are installed and secured by a suitable qualified person before transportation.
This makes the tank particularly suitable for mobile applications such as:
- Window cleaning
- Car valeting
- Vehicle cleaning
- Mobile pressure washing
- Commercial cleaning equipment
- Mobile water supply
The baffle system helps reduce liquid movement but does not eliminate it completely. The tank must therefore be properly installed and securely restrained before transportation.
Visible Water Level
The natural version of the tank features a translucent finish, allowing the water level to be viewed through the tank.
This provides a convenient way to monitor the remaining water supply without having to remove the lid, which can be particularly useful for mobile cleaning and valeting applications.
Coloured tank options are also available where a specific appearance or colour is preferred.
