Innovative Design Features:
- Flush-to-Ground Lid: The system’s lid is designed to be flush with the ground. Helping to preserve the look of your garden and eliminating any unsightly protrusions.
- Vehicle Loading Lid: This unique feature allows for installation in limited spaces, such as driveways, without compromising space or appearance.
- Integrated Sampling Chamber: The built-in sampling chamber streamlines your quality assurance process, saving you time and money by eliminating the need for additional installations.
- Gravel Backfill: This installation method suits various ground conditions and is cost-effective, saving you significant installation costs compared to traditional methods.
- No Moving Parts: The simplicity of design with no moving parts or electrical components inside the tank makes maintenance easy and efficient. All servicing can be handled via an external control panel and compressor, ensuring a hassle-free experience.

Delivery
All our Graf tanks are for delivery by customer offload. This entails the customer to acquire the right manpower and/or machinery to help unload the tank/s from the delivery vehicle.
If you require assistance with offloading, we may be able to offer a tail lift (lowers the tank to the ground) or HIAB (lorry with a mounted crane to winch the tank off to the nearest hardstanding area only, at an additional cost). Please contact us if this is required for delivery.

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.

We recommend that installers, plant hire and installation materials — excavators, aggregates and so on — are not booked until you are in receipt of the goods. Tanks Direct cannot be held responsible for costs incurred due to unforeseen delays; please see our terms for more details.
