The Water Game
The average person in the U.K. uses 150 litres of water per day. In this game it is Saturday at the
Waters family’s house. You must help them to use water wisely as they go through their day. Add up
how much water they use after each task and see how much water you can save them.
Mr and Mrs Waters have three children. With five people in the house they use about 750 litres of
water a day. Help them to use less. The cards will give you useful information.
Saturday Morning
1.
2.
Each member of the family must get up, have a wash and clean their teeth. Choose the two
cards that will save them water. Remember to multiply these amounts of water by five as there
are five people in the family.
All members of the family go to the toilet in the morning. They all must flush the toilet
afterwards. Choose the best toilet card for them. Multiply this by five people.
During the day

7.
8.
During the rest of the day each person in the family will wee three times. How can the Waters
family cut down on their water usage? You can use a card or use some ideas of your own.
Mrs Waters hates washing the dishes and would like a dishwasher. Mr Waters thinks a dish
washer uses too much water. Find out if Mr Waters is correct. Choose the card that will save
them water and add this value onto the total.
Mr Waters plays a lot of sport and will often put a half load of sports clothes into the washing
machine. The family need to do two full loads of washing a day. How can you save water by
washing wisely?
The children earn pocket money by washing the two family cars and watering the garden. They
want to earn lots of money but they are only allowed to use 100 litres of water to do everything.
Can you help them to do this? Remember to add this onto your total and explain how you will
do it.
The family all like to drink chilled water. Decide how much each member is allowed to drink in
one day and choose a card to help them. Remember, drinking water is something you should
not cut down on as it is good for you.
The family have two taps in the house that need fixing. They drip constantly. Find a card that
will stop this wasted water.
Bed Time
9.
Mr Waters has a shower every evening. Find the most water saving type of shower and add this
to the total.
10. On Saturday night the two younger children have either a bath or a shower. How can you clean
both children using the smallest amount of water? Add this to the total.
11. Mrs Waters and the oldest child just have a quick wash. Add this onto the total.
12. All family members clean their teeth and go to bed. Add the amount for each person onto your
total.
Finally
Look through the day and see if you can find more ways to save water
