Water Storage Tanks

Please contact us with the style of storage tank required, capacity and where you would like it delivered as some larger 25,000 litre tanks require specialist vehicles.

Manufactured in the UK, these quality water tanks are made from high grade polyethylene. The professional design and manufacturing processes are all done 'in house' which allows Merlin to offer you a bespoke design and a next day service if required. All the tanks use UK standard fittings, which mean you can use any of your existing fittings.
