Memorandum

The ways in which having running water in the home makes life easier.

• We can bath or shower without first having to fetch water.
• We do not have to fetch water to wash dishes.
• Having running water in the home saves time and energy.
• Laundry can be washed easily, our hands are not exposed to the chemicals in soap powders (if you have washing machine!)
• It is easier to keep everything clean and neat.
• We can have flush toilets, so we merely pull a chain and everything remains clean and free of germs.
• We merely have to turn the tap to be able to wash vegetables before eating or cooking them.
• We have drinking water available all the time.

It is easy to bath and take care of pets if we have clean water.
