1250 Litre Underground “Nugget” water tank

  • Diameter 1260mm
  • Height 1140mm


The Poly Water Tanks 1250 Litre Underground “Nugget” water tank is the perfect solution when you don’t have space to install a round water tank or slimline rain water storage tank beside your house or maybe you just don’t like the look of a water tank around your house.

Out of sight, out of mind, the 1250 litre underground rainwater storage tank is easy to install under your garden or under the concrete driveway. Once installed all you see is the access inspection plate.

If the underground tank is to be installed under a concrete driveway or on a sloping site then the 300mm adjustable riser will need to be fitted to the underground water tank.

With underground tanks, always use a submersible pump. We recommend Claytech Submersible pumps with an Aquasaver change over switch.
