Water Diaries: The results and some conclusions

At the end of last term pupils in Kafuro and Liss kept water usage diaries for a week to see how much water they consumed. All the data was submitted to Mr Stanley at the end of the Easter holidays and he has now compiled it. The results are fascinating.

At Liss Junior School the diaries were completed by 167 pupils. The average amount of water used per pupil per day is listed below by class:

KR  191.1526 litres

AS  135.1179 litres

MG  164.4218 litres

KB  116.6968 litres

DC  113.875 litres

NL  160.7535 litres

BM  174.4305 litres

JA  146.3571 litres

At Kafuro Primary School the diaries were completed by 27 pupils in classes P6 & P7. The average amount of water used per pupil per day is listed below by class:

P7  9.5275 litres

P6  7.237 litres

 

The average water use per pupil at Liss is: 150.35 litres of water per pupil per day

The average water use per pupil at Kafuro is: 8.38 litres of water per pupil per day

A Liss pupil uses nearly 18 times as much water in one day than a Kafuro pupil.

So why is water consumption so much higher at Liss than at Kafuro? Here are some ideas:

•There is very little running water in Kafuro. There is one pipe that runs through the village but that works inconsistently.

•People have to go and fetch water from the crater lake. This can often be a long walk.

•Jerry cans full of water are very heavy (Mr Stanley has first hand experience of this) and it takes a lot of effort to carry them any distance.

•Before drinking the water it must be boiled otherwise the children risk getting very ill from untreated water.

 

•In Liss clean treated water is piped into our houses and is available to drink 24 hours a day

•The water is also used in baths, sinks, washing machines, dishwashers and watering gardens.

•There is no effort needed to obtain the water. Simply turn on a tap.

 

Mr Stanley picked two children at random to compare their water usage:

On a typical day:

Liss pupil

Brushing teeth (tap switched on): 10 litres

Washing hands and face: 15 litres

Bath: 80 litres

Flushing toilet: 14 litres

Drinking: 0.9 litres

Washing machine load: 70 litres

Dishwasher: 60 litres

Total: 249.9 litres

 

Kafuro pupil

Bathing: 14 litres

Drinking: 2 litres

Washing: 12 litres

Total: 28 litres

 

 

So how can more water be conserved at Liss. Here are some suggestions:

 

•Whenever you wash your hands, don’t leave the water running. Wet your hands and turn the water off. Use soap and lather your hands well, then turn the water on to rinse. Turn off the water and make sure it is off completely. Then dry your hands.

•Do the same when you brush your teeth. Turn the faucet on to get your toothbrush and toothpaste wet, and then again to rinse your mouth and toothbrush. Don’t leave the water running while you’re brushing.

•Since baths use a lot of water (about 37 gallons on average), take short showers instead and use only about 20 gallons of water, instead.

•Use a wastebasket for used tissues, or things like gum wrappers, paper towels, or even dead bugs or goldfish. Don’t flush them – the average flush uses as much as 5 gallons of water! Even if the toilets in your house are “low-flow” toilets, using them for trash still uses 1.5 gallons of water unnecessarily.

•Do you have plants in your house? When meals are prepared and vegetables or other fresh produce are washed, collect that water and use it to water the plants.

•Do you like a drink of cold water now and then? Rather than running the kitchen faucet for several minutes to get cold water, keep a pitcher of water in the refrigerator.

•Put a barrel outdoors to catch rain water, then use that water for things like watering plants or flushing toilets and save hundreds of gallons of water a year!

•If the adults in your home occasionally water the lawn, encourage them to water in the cooler parts of the day (early morning, or at or after sunset), and never on windy days. This keeps in the soil all the water being sprayed instead of most of the water being lost to evaporation.

•If there is a dishwasher in your house, encourage everyone to scrape their plates rather than rinse them before loading them into the machine. It should always be full before turning it on.

 

We would like to invite pupils and parents at both Liss and Kafuro to post comments with other ideas how to conserve water.
