900 Litre D-Shaped Upright Water Tank
Product Overview
The 900 Litre D-Shaped Upright Water Tank is a robust and versatile solution for the storage of potable water, non-potable water and a wide range of other compatible liquids.
Manufactured from durable MDPE / polyethylene, this upright tank provides a substantial nominal capacity of 900 litres, equivalent to approximately 238 imperial gallons. Its D-shaped design provides a practical footprint while allowing the tank to make efficient use of vertical space.
The tank is particularly well suited to applications where a large volume of water is required in a relatively compact footprint, including window cleaning, car valeting, agricultural applications, horticulture, commercial water storage and general-purpose water supply systems.
Manufactured in a natural translucent medium-density polyethylene, the tank allows the approximate water level to be viewed through the tank wall. This provides a convenient way to monitor the remaining contents without needing to open the tank.
The tank features a 1" BSP outlet and a large 16" vented lid, providing convenient access for filling, inspection and cleaning, together with a practical connection point for compatible taps, hoses, pumps and pipework.
The manufacturer's stated empty weight is approximately 33 kg, making the tank considerably easier to position before filling than when fully loaded.
Please note that although the product is marketed as a 900 litre tank, the manufacturer states a maximum capacity of approximately 840 litres.

- Agricultural applications
- Horticultural applications
- Commercial water storage

The tank should be installed on a suitable, stable and adequately supported surface.
Window Cleaning & Car Valeting
The 900 litre D-shaped tank is specifically described by the manufacturer as suitable for window cleaning and car valeting water storage.
Its substantial capacity makes it particularly useful for businesses that need to store a large volume of water on site or as part of a water supply system.
Potential applications include:
- Professional window cleaning
- Pure water systems
- Car valeting
- Mobile vehicle cleaning
- Commercial cleaning
- Pressure washing
- Water-fed cleaning systems
- General commercial water storage
The large capacity provides a useful reserve of water while the upright footprint helps keep the required floor area relatively compact.

- Mobile vehicle cleaning
- Potable water storage
- Non-potable water storage

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.
