Measuring Flow Rates
Flow Rate Prior to Efficiency Audit
Recommended Flow Rate
Vanity Basins >12 litres per minute 6 litres per minute
Sinks and troughs 15 litres per minute 9 litres per minute
Showers 15-20 litres per minute
12 litres per minute
*** 10 ***
Solution / Deliverables
• Installation of 2441 flow control valves
• Estimated saving 20,611,000 litres of water for three campuses
• Cost of audit and implementation $90,000
• Pay back 2 years
