asic water audit
worksheet 5
Leaking taps and pipes drip water at different rates - over a whole year the total for each leak can vary from hundreds of litres
to many thousands of litres. The total of water wasted from all leaks is not only a significant amount, it also costs the school
hundreds of dollars. To work out the actual amount of water and money that is wasted every year at your school from ALL leaks
complete the following two tables.
Enter your figures from the previous page into the first table below.
LEAKAGE RATE LITRES PER MINUTE LITRES PER YEAR KILOLITRES PER
YEAR
YEARLY COST
Slow Leak:
Medium Leak:
Fast Leak:
Major Break:
If you have completed the water audit on the previous page, you can now calculate total water loss and costs.
For example, if a slow leak loses 10.5 kL/yr then 30 slow leaks is 30 x 10.5 = 315kL, x $1.01kL = $318.15
Complete the table below using the results of your water audit and your leakage rates from the table above.
Note: calculating the water losses from major breaks can be hard to estimate, as they usually occur for short periods of time. Find
out if there have been any major leaks or breaks at your school in the last 12 months and estimate how much water was probably
lost and the cost of this water.
