Damsak is a cost effective, patented bladder reservoir for nearly all liquids.

Manufactured since 2007 from polyester reinforced potable grade, plasticised polyvinyl-chloride (PVC), making it exceptionally strong.

The special shape causes a Damsak to rise up while being filled without any additional structure needed.

Damsak has a longer lifespan than conventional mesh and vinyl reservoirs.

Our very first Damsak that was manufactured in 2007 is still operational and in very good condition.

Algae will not grow inside. Water is stored in a closed and dark environment.

Damsak is a closed tank, there is no evaporation or contamination.
