About Non-Potable Water Tanks

Manufactured from high-quality UV-stabilised polyethylene, our non-potable water tanks are designed to provide years of dependable service, outdoors within the elements. Available in a wide range of capacities, shapes and colours, you'll find tanks suitable for everything from small garden projects through to large-scale commercial water storage.

Whether you're collecting rainwater to reduce mains water consumption, storing water for agricultural use or creating a reserve supply for cleaning and maintenance, our extensive range includes many options. Upright tanks, slimline tanks, horizontal tanks, baffled tanks and underground water tanks to suit almost any installation.

Why Choose a Non-Potable Water Tank?

Using non-potable water for suitable applications can help reduce water bills, improve sustainability and lessen demand on treated mains water supplies. These tanks are commonly used for:

  • Rainwater harvesting systems
  • Garden and landscape irrigation
  • Agricultural and livestock watering
  • Pressure washing and vehicle washdown
  • Construction and site water storage
  • Industrial process water
  • Emergency water reserves
  • Cleaning machinery and equipment

Because these tanks are intended for non-drinking water, they offer an economical solution for applications where potable water approval is not required.

Quality Water Storage Solutions

At Online Tank Store, we supply non-potable water tanks from leading UK manufacturers including Enduramaxx, Atlantis, Tuffa, Wydale and other trusted brands. Many tanks are manufactured in the UK and are backed by comprehensive manufacturer warranties for complete peace of mind.

With capacities ranging from under 100 litres to over 30,000 litres, we can supply water storage solutions for homeowners, farms, businesses, contractors and industrial facilities alike. The tanks can also be combined to offer significant storage capacity.

If you're unsure which non-potable water tank is right for your application, our experienced team is always happy to help you choose the most suitable size and specification.
