How to Keep Your Water Tank Safe and Healthy


Water tanks must be taken care properly to reduce pollutions. Strictly prohibit swimming and other such instances of human contact in your water tanks, as it will greatly increase possibilities of contamination.

Cover the inlet and turn the down-pipe to one side so that the water from the first rain rinses down the roof (especially if newly clad) and gutters, and then runs to waste.

Make sure the tank, the roof and the pipes are all made of approved materials. Use only “food grade” plastic pipes, if you are planning to drink the stored water.

Ways to Maintain Your Water Tanks

Maintenance of your water tanks should be carried out before the arrival of the rainy season.

  • Check the tank walls, the roof, the pipes, the meshes and all the inlets for holes or cracks, which may give access to birds and animals and mosquitoes.
  • Clean the tank inlet and the gutters every three or four months.
  • Keep the roof catchment clean and free of leaves and droppings.
  • Remove the sludge at the bottom of the tank every two to three years, by the desludging process.
  • You can boil the stored water for maximum removal of germs.
  • Go for water tanks, in case of a major problem.

By employing these simple means, you can be sure that the rainwater collected in your water tanks is safe and germ-free.

The installation of the tanks should be done by a licensed and experienced plumber to avoid leakages. Moreover, special care has to be taken to give different inlets in the house from the mains and from the rain water tanks.
