75 Litre Flat Water Tank
Product Overview
The 75 Litre Flat Water Tank is a compact, versatile and durable solution for the storage and transportation of potable water and a wide range of other compatible liquids.
Manufactured from durable HDPE / medium-density polyethylene, this low-profile rectangular tank provides a practical 75 litre storage capacity, making it particularly suitable for applications where available space is limited.
The flat configuration allows the tank to make efficient use of floor or vehicle space, while its relatively low height makes it useful for installations where vertical clearance is restricted.
The tank is supplied in a natural translucent finish, 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 standard configuration includes a 3/4" BSP outlet and an 8" lid, with optional outlet positions and fittings available to adapt the tank to different applications.
At approximately 6 kg when empty, the tank is lightweight and easy to handle and position before filling.

Compact Low-Profile Design
With dimensions of approximately 450 × 600 × 300 mm, the 75 Litre Flat Water Tank has been designed to provide useful water storage while keeping the overall height to a minimum.
Its rectangular, low-profile configuration makes it particularly useful where conventional upright tanks are unsuitable because of restricted headroom.
The tank can be incorporated into a wide range of above-ground installations and can be particularly useful for:
- Vehicle-based water systems
- Cleaning equipment
- Agricultural applications
- Horticultural applications
- Commercial equipment
- Workshops
- Portable water systems
- General-purpose water storage
At approximately 6 kg when empty, the tank can be readily positioned before filling.
Once full, the tank will contain approximately 75 kg of water, in addition to the weight of the tank and any installed accessories. The supporting surface must therefore be capable of safely supporting the total filled
Applications

- Window cleaning
- Commercial cleaning
- Agricultural applications
- Horticultural applications

- Temporary water storage
- Portable water supplies
- General-purpose liquid storage
Its flat, low-profile design makes it particularly useful where available vertical space is restricted.
