Onion Tanks

Here at Ridge Product Services, we are able to supply Onion tanks to a wide range of industries and markets throughout the UK. Onion tanks are commonly referred to as ”pumpkin tanks” due to the way that they are manufactured and are mainly used for successfully storing both non-potable and potable water. These flexible Onion tanks can be easily supplied to any location. When emptied, they can be easily folded and stored for re-use at any time or re-located. For more information or to make your order today, please call us now on 07824 690 143.

Onion tanks are manufactured in the UK, specifically in a dedicated ISO9001 approved factory and tested before being sent out to customers. These types of tanks are generally manufactured from high-quality, medium and heavy-duty PVC materials with top covers/ground covers available.

Onion tanks are used for a wide range of applications including decontamination and emergency water supply. They are also commonly used in response to leaks to collect liquid as it flows from the device.

Ridge Product Services are able to supply and install onion tanks in Manchester, Liverpool, Chester, Preston Sheffield, Birmingham, and throughout the UK.

Onion Tanks – Uses

As well as being widely used for decontamination and the mentioned-above uses, Onion tanks are also used for a number of further applications and industries. Below are just a few of the further uses of our Onion tanks that can be manufactured to suit your unique specifications;-

  • Onion tanks can be used to store drinking (potable) water
  • Onion tanks can also be used as storage for food-grade liquids.
  • For temporary storing liquids during decontamination operations.
  • Used in remote locations (for example, for mining camps).
  • Beneficial for construction sites to help with efficient water storage.
  • For storing and collecting rainwater.

Onion tanks are a great option for many uses and applications, and they provide a number of benefits which makes them so popular. They are really easy to setup which means there will be little hassle after supply. Furthermore, Onion tanks are self-supporting and therefore require very little maintenance as they can rise on their own. Onion tanks also provide really efficient collection, easy access, and fast fill.

Perhaps one of the most underestimated benefits of these types of tanks is the fact that they are collapsible and can be easily transferred to other sites. Even when storing large volumes of liquid, these tanks can be quickly emptied and deployed. Further benefits and reasons why Onion tanks (also known as bladder tanks) are so popular include;-

  • Manufactured from highly durable materials making them long-lasting.
  • Beneficial for emergency drinking water storage.
  • They can be easily stored in a wide range of outdoor areas.
  • Storage space is minimised when not in use.
  • Highly flexible storage solution for water.
