Shallow Dig Tanks

The F-line shallow dig tank can be installed into much higher water tables than a standard round tank. If you don’t know what your water table will be like in the winter, you’re safer to install a flat tank.

The F-Line tanks are flat and the installation depth is 60% less than other rainwater tanks. The excavation can be up to 70% less, meaning little earth excavation, easy handling and less cost for you!

The small excavation pit is easily filled in and your garden will look just like it did before.

Over the years the shallow dig tanks have become the more popular tank to purchase as part of a Rainwater Harvesting System.

All of our shallow dig tanks come pre-fitted with the filter, calmed inlet and overflow siphon, making it a simple case of lowering the tank in the ground and connecting the in and out pipes.
