What are the features and benefits of having an underground rainwater tank installed?

  • Safety is one of our biggest concerns, our tanks come with a lockable, three stainless steel bolt cover with a 600mm clear opening to allow for easy access and ongoing maintenance.
  • Our tanks are strong, and very safe.
  • Tank covers are lightweight and have a water tight seal.
  • Different height turrets vary the inlet depth to create the fall of the tank which makes them suitable for any light traffic areas.
  • We find the best location and depth for your water tank, this is to ensure maximum fall to the tank. This means that every single drop of rain can be harvested – giving you maximum storage while eliminating sediment build up in the pipes.
  • Our tanks are flush to the ground and out of sight, this means they can be positioned under driveways or gardens.
  • Fitted to our tanks is an overflow, this full flow flap valve stops any vermin from entering the tank and stops the backflow water from entering. It does not restrict the overflow.
  • Coming with a high performance stainless steel pump, which has been designed to operate efficiently assuring you of long-term performance. It works quietly inside the tank providing you with a constant supply of rainwater to the rain switch.
