RainCell household rainwater harvesting system

  1. Rainwater capture Rainwater runs off roof into downpipes and flows towards tank inlet
  2. Filter assembly Rainwater is filtered before entering tank to remove leaves, debris and contaminants
  3. Overflow Initial unfiltered water/debris flows to soakaway (via leaf filter), drain or surface water
  4. Calmed inlet Reduces water turbulence on entering tank chamber so any base silt remains undisturbed
  5. Floating suction point Draws clean water into pump
  6. Stainless steel pump Pumps recycled rainwater to houshold appliances, garden taps, and irrigation systems
  7. Underground conduit Carries pipework and electrical cables to and from tank
  8. Household controller Controls the distribution of rainwater from tank to household appliances. Also ensures tank is supplied with mains water if rainwater level too low. (RainCell Home & Garden)
  9. ‘ELITE’ level sensor probe Detects the amount of water in tank
  10. ‘ELITE’ indicator panel ‘Elite’ option provides additional level indicator for visible display of tank volume
