CISTERN LINERS

DLM Plastics has been a leading manufacturer of cistern liners, Rainwater Harvesting liners, catchment tank liners and other potable water containment applications for well over 30 years. Our liners are used in both new installations and retrofit projects to provide an impermeable barrier to eliminate leaks caused by cracking or porous surfaces inside your tank.  Our engineers have become quite adept at finding solutions for such irregularities as multiple chambers with flow-throughs and overflow notches, support columns, pipe penetrations and sump wells.

 

We provide cistern, Rainwater Harvesting and catchment tank liners in a variety of materials:

  • Potable-Grade Materials
    We carry several options in both film (single-layer) and supported (multi-layer with rip-stop scrim) which are NSF-61 approved for drinking water installations.

     

  • Non-Potable Grade Materials
    We provide numerous options in both film (single-layer) and supported (multi-layer with rip-stop scrim) styles and all are based on the application: 
     

    • General Household Use
           (non-drinking)

    • Irrigation

    • Livestock

    • Fire Suppression Systems

    • General Purpose

We offer several attachment methods for hanging your liner into place.  Cistern liner attachment methods include:

  • Hem and Batten
    We weld a hem at the top of the liner wall to provide a double-layer for added strength.  The installer holds the liner up to the appropriate level, holds a batten strip in place and then screws directly through the batten and liner into the wall.

     

  • Beaded with Track
    We supply a PVC track that is pre-hung in the tank by the installer.  Then, weld a molded lip at the top of the liner wall that simply hooks into the track and the liner is installed.

     

  • Overlap
    Typically used in open-top tanks, we add an extra amount of material at the top of the wall that is either laid-flat onto the top surface or folded over the top of the wall.

Combine our years of experience with our use of application-specific materials and our variety of attachment styles and you will see that we have a distinct advantage over other suppliers. Don’t settle for second best. After all, when it comes to healthy water used in and around your home – especially drinking water – you can never be too careful.
