105 Litre Flat Water Tank
Product Overview
The 105 Litre Flat Water Tank is a compact, low-profile solution for storing and transporting potable water and a wide range of other compatible liquids.
Manufactured from durable HDPE / polyethylene, the tank's flat configuration provides a broad footprint while keeping the overall height to just 300 mm. This makes it particularly useful where available headroom is restricted or where a low-profile tank is required.
The natural translucent finish allows the water level to be viewed through the tank wall, providing a simple way to monitor the tank contents without opening the lid.
With a standard 3/4" BSP outlet and 6" lid, the tank offers straightforward filling, inspection and connection to compatible water-handling equipment.

Low-Profile Flat Design
The key benefit of this tank is its low overall height.
At approximately 300 mm high, the 105 litre tank is well suited to applications where vertical space is restricted. Its 500 × 750 mm footprint provides a practical storage solution without the additional height of an upright tank.
This makes it particularly useful for mobile equipment, vehicle installations, commercial equipment and other applications where a compact flat tank is preferred.
Applications
The 105 Litre Flat Water Tank can be used for a variety of applications, including:
- Potable water storage
- Mobile water storage
- Window cleaning
- Vehicle valeting and detailing
- Mobile cleaning equipment
- Agricultural and horticultural applications
- Commercial equipment
- Site and construction applications
- Temporary water storage
- General-purpose liquid storage and transportation
The tank should only be used with liquids that are compatible with the tank material and selected fittings.

Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international 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.
