asic water audit
worksheet 5
You can undertake a basic water audit of your school using the table below to record the total number of water outlets and how
many are leaking and at what rate. To avoid double counting it is a good idea to get copies of a map of your school and assign
teams to different zones.

EXPERIMENT:
To find out how much water leaking taps and pipes can waste conduct the following experiment:
1 Place 3 measuring jugs under 3 leaking taps (ie slow, medium and fast dripping leaks)
2 Start the Stop Watch
3 Stop the Stop Watch after set time, eg 5 minutes
4 Measure the volume of water collected in millilitres (mL) and divide by 1000 convert to litres
5 Divide the the total number of litres collected by the number of minutes
You now have figures for how many litres of water per minute different leaks waste:
Multiply these by 60 for hourly rates: slow: L/hr medium: L/hr fast: L/hr
Multiply above by 24 for daily rates: slow: L/day medium: L/day fast: L/day
Mutliply above by 365 for yearly rates: slow: L/yr medium: L/yr fast: L/yr
To to see how much money these leaks cost your school each year, divide the yearly litres by 1000 to convert it
to kilolitres, then times this by the cost per kilolitre (this is stated on your water bill).
A slow leak costs $ per year
A medium leak costs $ per year
A fast leak costs $ per year
