How do I know what Size Liner I need?

In order to size and price the best cistern liner for your existing unit, we typically ask customers to provide us with some additional information regarding their tank construction and storage needs. Information needed includes:

  • Size & Shape of your Cistern
    (example: Circular, dimensions 6' diameter and 10' high)

  • Liquid Requirements
    (Do you need the the liner to be FDA and NSF 61 approved for drinking water?)

  • Cistern Material (example: concrete, steel, etc.)

  • Piping, Plumbing or Hardware in the Location
    (Any equipment you will need the liner to work around?)

After providing us with this information, we will work to find the best sizing option and fabric material to meet the storage requirements of your location. This may include extra fabric to go over the side of the cistern or other options to help with securing the liner to the tank.

How do I Secure the Liner to the Cistern?

When looking for cistern tank liners, many customers are additionally interested in learning how to attach these liners to their tanks. Some of the most common methods used for cistern liner attachment includes the following options:

  • Banding Along the Top of the Tank (either plastic or steel)
  • Secure Banding to the Tank and the Liner through Gaskets

Customers may additionally add a geotextile fabric material between the tank and the liner. This helps to further retain water and protect the liner against any abrasion during its use.

If you have any additional questions regarding these liners and how they can be used, please don't hesitate to contact us by email: or by phone: 1-772-646-4545.

If you need a liner to fit your tank, we have an option that can meet your needs.
