THE COST OF WASTE...
Easily Identified Costs
Hidden Costs
10
Overuses of water

• Excessive or unnecessary use
• Unknown or unauthorised use
• Unidentified or cross connections
• Broken valves
• Incorrectly set valves or control systems
• Leaks, etc

11
Water losses from a tap

• 3 mm stream
• 600 cm3/minute
• 336 m3/year
• 193 - 519/year

There are a lot of minutes in a year!!
