From Sensus website:

• One-third of utilities around the globe report a loss of more than 40-precent of clean water due to leaks
• Reducing leaks by 5 percent, coupled with up to a 10 percent reduction in pipe bursts, can save utilities up to $4.6 billion every year
• With a smart water network, many public service providers immediately discover a daily loss of thousands of gallons of water due to leaks. One utility even found a single leak causing 200,000 gallons of water loss each day
