CISTERN PRODUCTS

DLM Plastics has been a leading manufacturer of cistern liners, catchment tank liners and other potable water containment applications for well over 20 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, pipe penetrations and sump wells. Our cistern and catchment tank liners are available in a variety of potable and non-potable grade materials including some that are NSF-approved for drinking water. In addition, we offer numerous attachment methods for hanging your liner into place.
