Damsak 6000L Bladder Water Tank 3m x 2.4m x 0.55m

Folded PVC reservoir for bulk liquid storage

The Damsak 6000L bladder tank is a patented folded reservoir that rises as it fills and needs no steel frame or concrete base. Nominal footprint measures 3 m by 2.4 m by 0.55 m. The unit ships folded at 46 x 40 x 30 cm and weighs 16 kg.

Polyester-reinforced PVC forms the body, and welded corners hold their shape under fill pressure. A 25 mm ball valve is the standard outlet, while a 75 mm top vent with riser pipe works as breather and overflow. The closed, dark interior blocks light, so algae does not grow inside.

Site the empty bladder on level, cleared ground free of sharp stone. Check the layflat footprint against the platform before filling starts. No foundation, crane or specialist tool is needed. Leave the top vent open at all times, because it regulates capacity and releases air during fill and draw-off.

Rainwater harvesting, irrigation lines, pool top-up, fire reserve and event supply all suit the 6,000 litre unit. A pressure pump connects to the ball valve outlet for distribution. The body stores potable water and most liquid fertilisers without contamination. A 10-year warranty covers the moulding and welded seams.

Key Features

• Self-rising bladder design
  The welded PVC shell lifts as it fills, so the reservoir needs no rigid tank wall or support cage.

• Polyester-reinforced PVC body

  • Reinforced fabric resists puncture and UV exposure
  • Welded seams carry the fill load without stitching
  • Suitable for potable water and most liquid fertilisers

• 25 mm ball valve outlet
  The standard side or bottom connection feeds a pressure pump or gravity line.

• 75 mm top vent with riser pipe
  The vent acts as breather, overflow and capacity regulator, and it must stay open.

• Closed, light-blocking interior
  Stored liquid sits in a dark sealed volume, which stops algae growth and evaporation loss.

• Compact folded shipping size
  At 46 x 40 x 30 cm and 16 kg, the empty unit moves in a bakkie or trailer without a crane.

• Ten-year warranty
  The manufacturer backs the moulding and welded seams for a decade of service.
