A recent study suggested local schools are spending almost half a million dollars on lost water. That equates to more than 70 Olympic sized swimming pools of water going down the drain every year.
To help local schools save money on their water bill, Hunter Water provided data loggers to 65 local schools which were then connected to their water meter to track water usage in real time via the internet.
This program involved schools' water meters being fitted with an electronic device that measured water usage in real time and relayed the information to an electronic portal that could be viewed by teachers, students, administrators and the Water Efficiency team at Hunter Water.
Alerts were set up through the online portal to be sent to mobile phones and/or email to notify staff if there is a spike in water usage overnight or on weekends, indicating a leak. These leaks are often in underground pipes and can waste many thousands of litres per day, costing schools thousands of dollars in water usage charges.
The portal was also used in subjects such as maths and geography to teach students how to use a graph and to demonstrate the school's water usage peaks and troughs.

Leak at Hunter School of Performing Arts - September 2013
The data logger picked up a large leak in a burst pipe under the school administration office. With a leakage rate of 20L/minute, the leak was costing the school $77 in extra charges per day. Without the data logger the leak might have gone undetected until the next bill in November, potentially adding $7,000 to the school's water bill.
