Our practical challenge today is to do a water audit at church. This can be a fun activity to be done with the youth or Sunday School.  You will need a notebook or paper to make spreadsheet.


  1. Running water:
  • Find the water meter …. Take a reading
  • Turn off all other water users
  • Fill pot/bucket by running water for 30 seconds
  • Take another water reading
  • Calculate how much water is running through the pipes, in litres/minute or litres per second
  • If hosepipes are used for gardening or washing cars or paving, find out for how many minutes and calculate the amount of water used per day.
  • Enter onto your spreadsheet


2 Toilet and basins for hand washing

  • Lift the cistern lid
  • Hold water tap off and flush the loo
  • Keeping the intake water closed off, use your measuring bottle to fill the cistern, measuring how much water is used.
  • Find out how many times a day the toilet is flushed, and calculate the amount of water that is used during the day. Repeat for any other toilets.
  • Wash your hands in the basin, and calculate the amount of water you use.


  1. Kitchen water use

Calculate the amount of water used for an event – e.g. a church service on a Sunday

  • If cooking a meal, how many pots and using your measuring bottle, calculate how much water is used to cook food.
  • Kettle/urn – how much water does the kettle/urn hold – use your measuring bottle to find out
  • How many times is the kettle boiled to make enough tea?
  • For washing up, what size sink or bowl is used (use your measuring bottle to calculate the volume)
  • How many bowls, sinks of water does it take to wash up the pots?
  • Are the pots, cups, plates etc. rinsed as well?
  • Where does the water go? Down the drain or onto the vegetable garden?
  • For washing cloths and for washing the floor: how much water per week (no of buckets) and no of times the floor is washed per week.

All this information is added onto your spreadsheet

e.g Hall Toilet Cistern 5 liters per flush  5 x 200 flushes = 1000 liters
