What is a Septic Tank?

A septic tank consists of a two or three chamber system that retains sewage from a property for sufficient time to allow the solids to form into sludge at the base of the tank, where it is partially broken down through anaerobic digestion. The remaining liquid in the tank then overflows from the tank by means of an outlet pipe to a drainage field. Septic Tanks have a 1.0m standard invert depth.

Delivery

All the Klargester 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.

Looking to avoid shipping charges?

All our tanks are available for collection ex works. Our suppliers are based all over the UK — please call if you wish to collect.

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.

Offloading

Unless a HIAB delivery has been booked at additional cost, it is the customer’s responsibility to offload with suitable equipment on the day of delivery. A failed delivery may result in additional charges.

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.
