Water Tanks under 10,000 Litres are ideal to be used under decking and come complete with lifting lugs for easy manoeuvring. Multiple tanks can be connected together using up to 4" Outlet Pipes.

Large Water Tanks with a capacity over 10,000 Litres have been designed to be lifted and manoeuvred only when empty and should never contain water when doing so. These tanks should be unloaded, moved and lowered into position by attaching lifting chains and D-Shackles or lifting straps around the tank.

Large Water Tanks are fully encased in concrete and have been designed to take pedestrian traffic only – if the tank is required to carry traffic, a structural engineer's design is required. When installing, the top of the tank must not finish any more than 500mm below ground level. Without a structural engineer's design, the tank must not be located adjacent to foundations, raised banks, patios or walls.

At Safe Fence, we supply a range of connections and fittings suitable for agricultural, commercial and domestic applications:

  • Water Pump – electronically controlled, pressure-sensitive, submersible, centrifugal, roto-dynamic pump with no reciprocating parts.
  • Float Valve & Float – these control the filling of a tank so that it can be flushed.
  • Byelaw Kit – components designed to protect the water in a tank from contamination.
  • Valves – robust brass valves which are excellent for isolating equipment from your install for maintenance.
