Full Description

The new Silentio range by Graf offers exceptional water quality for non-potable water uses inside and outside of the home.

This tank will save you money in many ways. Firstly, by reusing rainwater as a natural resource, you will save money in the long run on your water bills, as well as practising sustainability. Also, during installation, this tank only requires a granular backfill, as opposed to concrete. This will save you up to £60 per cubic metre. It also makes installation much easier. See the installation guide above for more details.

This 4,800 litre Carat Silentio tank is made from 100% recycled plastic. So, not only are you helping the planet by reusing rainwater, the tank itself is made from reusable materials.
