JFC supply a range of underground rainwater harvesting tanks suitable for potable and non-potable use.

If using the harvested water for dishwashers or washing machines a Micron Filter is also required. A UV Sterilizer is also necessary if using the water for hand basins or sinks. Drinkable water sources should be fed direct from the mains (kitchen tap etc.)

Features & Benefits:

  • Reduced water charges : tank acts a reserve during periods of water shortages
  • Tank installation: Unlike other tanks which require concrete back-fill, JFC underground tanks can be back-filled with pea-gravel minimising the cost of installation
  • Installation in tight spaces: If space is tight or restricted the tank(s) can be assembled on-site (assembly instructions provided)
  • Water yield: The basket filters supplied with this system provide a 100% water yield (i.e. all of the water that flows via the downpipes into the tank will be harvested)
  • Automatic Mains-back-up systems ensure a continuous supply of water, even in the event of a power-cut.
  • A Pressure Vessel ensures that the pump is not activated every time someone flushes a toilet or uses a small amount of water from an outdoor tap for example. This helps to prolong the life of the pump.
