The tank that makes a mains-free toilet block work
A steel welfare cabin is only half the answer on a site with no drainage. This sit-on waste tank is the other half: it sits directly beneath a matching steel toilet unit of the same 4.88m footprint and takes everything the block produces, so the cabin above can be positioned wherever the site needs it rather than wherever a sewer connection happens to run.
Capacity is 6,500 litres, or 1,429 gallons, which is enough to keep a busy compound going between tanker visits instead of scheduling one every few days. Construction is all steel: an internal framework and supports clad in 2mm plate, primed in black. That is a deliberately heavy specification for a component that spends its life supporting a loaded cabin and being dragged into position by plant.
Two 150mm emptying points are fitted at the corners, each with a cover, so a tanker can pull up on whichever side of the unit the access allows.

Worth checking before you order: that the ground where it will sit is level and firm enough to take the tank plus a full cabin, and that a tanker can physically reach it. Free delivery is included, wherever in the UK you are.
