Cleaning of water storage tank

 
      We recommend the following steps for the cleaning of a household water storage tank:
  • Brush the bottom, sides and ceiling of the tank.
  • Wash out the dirty water.
  • Wash with clean water.
  •  
  • Disinfect with bleaching agent (Eau de Javel).  For a tank with a capacity of more than 1,000 litres, put in about 10ml of bleach.  Adjust accordingly for tanks of different capacities.
  • Leave the bleaching solution in for the night.
  • Wash out the bleaching solution.  The tank is now disinfected and can be used to store water for consumption.
  • Clean your water tank on a regular basis (at least once every six months) and make sure that the tank is properly covered to prevent contamination through algae formation or grub accumulation.
