## Teacher preparation

The focus on this audit is on plumbing.

An actual audit of water use is not presented as an activity. In a typical school about a third of the water used is through the toilets. Monitoring and collecting real data about toilet use is probably not practical.

Opening discussion

Discuss with students that they will be collecting data about the school’s plumbing. They will use their master maps from the previous activity to locate and inspect the plumbing. They will collect different kind of data for the major types of plumbing: taps, drinking fountains, toilets and garden/sports/lawn watering systems.

Check out the water meter – collect water consumption data

Before the audit starts, students can check out the water meter and take a reading to see how much water is used each day, and how much water is used over the weekend.

Water meters give readings in kilolitres. There are different kind of meters. The school’s will probably have rotating numbers, but it cou

### Tap audit

Use a copy of the school's master map to locate the school’s taps. You might like to use a colour pen to number the taps on the map and use the number as a location. Check each tap. Then tick the boxes that apply to each tap.

When completed use the data as part of a report. Highlight any aspects that require fixing. Explain what people need to do if the taps are not being used correctly.

### Garden /lawn/sport field watering system

Use a copy of the master map to locate where the school’s watering systems are located.  The purpose of this audit is to look for evidence of too much water being used to water outdoor areas.
