Less2Care has developed durable and ergonomic containers where the content can be unloaded through the bottom release plate that is build in the container.
This way you can easilly roll the 800 litre container over the underground storage. The lid of the galvanized and durable storage automatically opens via a light to handle system. Then the contents naturally falls down.
The lid closes automatically again when the MegaSan container is rolled off the underground storage container.
