500 Litre Water Tank, Upright, Baffled
Product Overview
The 500 Litre Upright Baffled Water Tank is a robust and versatile solution for the storage and transportation of potable water and a wide range of other compatible liquids.
Manufactured from durable MDPE / polyethylene, this upright tank provides a nominal capacity of 500 litres, equivalent to approximately 132 imperial gallons. Its upright rectangular design provides substantial water storage capacity while maintaining a practical footprint for above-ground and mobile applications.
The tank features an integrated internal baffling system specifically designed to reduce water movement during transportation. The baffles are formed through grooves and openings within the tank, helping to disrupt the movement of liquid and reduce side-to-side sloshing.
This makes the tank particularly well suited to mobile applications such as window cleaning, car valeting, vehicle cleaning and other situations where water needs to be transported.
The natural translucent finish allows the approximate water level to be viewed through the tank, making it easy to monitor the remaining contents.
With an empty weight of approximately 35 kg and dimensions of approximately 620 × 1000 × 920 mm, this tank offers a useful combination of high-capacity storage, durability and practical handling.
The standard tank is supplied with a 1" BSP outlet and 8" lid, with a range of optional accessories available to adapt the tank to different water storage and delivery systems.

Upright Design
The 500 Litre Upright Baffled Water Tank provides a substantial amount of water storage while maintaining a practical rectangular footprint.
Measuring approximately 620 × 1000 mm across the base and 920 mm in height, the upright configuration makes efficient use of available space while providing 500 litres of nominal storage capacity.
This makes it suitable for a wide variety of applications, including:
- Window cleaning
- Car valeting
- Mobile vehicle cleaning
- Commercial cleaning
- Potable water storage
- Agricultural applications
- Horticultural applications
- Irrigation
- Vehicle-based water systems
- Temporary water storage
- General-purpose liquid storage
The tank should be installed on a suitable, stable and adequately supported surface.
Integrated Baffle System
The tank incorporates an internal baffle system designed to reduce the movement of water during transportation.
The baffling is created through grooves and openings that run through the tank, disrupting the movement of the liquid and helping to prevent excessive side-to-side sloshing.
This is particularly beneficial for mobile applications where the tank may be transported with a substantial volume of water inside.
Typical applications include:
- Window cleaning
- Car valeting
- Mobile vehicle cleaning
- Commercial cleaning
- Mobile pressure washing
- Vehicle-based water systems
- Liquid transportation
Reducing water movement can help improve stability during transportation, although the baffles do not eliminate liquid movement completely.
The tank must therefore be correctly installed and securely restrained before transportation. Tanks containing large volumes of liquid can be extremely hazardous if incorrectly secured.
Please also note that the internal baffle design reduces the usable capacity of the tank.
Applications
The 500 Litre Upright Baffled Water Tank is particularly suitable for mobile and commercial water storage applications.
Typical uses include:
- 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 integrated baffling makes the tank particularly useful where water needs to be transported as part of a mobile operation.

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.
