• We also know that only a small percentage of water in the planet is usable. That makes it very precious.
• We should not waste water and this can begin at home, both indoors and outdoors.

There are few tips for saving water:

• Do not leave the tap running when you are brushing your teeth.
• When washing hands, do not leave the tap running while reaching for the soap or working those soap suds.
• Fix leaks as soon as possible.
• Run the washing machine and the dishwater only when they are full.
• Do not use sprinklers on the lawn. Use water from the kitchen sink or rainwater.
• Save the water used to wash vegetables and fruit. This can be used to water the plants in and outside the house.

• The process of collecting and storing rainwater from roofs or a surface catchment is called rainwater harvesting.
• Storing rainwater that collects on roofs instead of letting it go down the drain.
• This technique is known as rooftop rainwater harvesting.
