34%We currently withdraw 34% of the world's reliable runoff of surface water and could be using 90% by 2025.
Reliable runoff is surface runoff of water that generally can be counted on as a stable source of water from year to year. What is a watershed or drainage basin? A watershed (drainage basin) is and area that delivers water, sediment, and dissolved substances via small streams to a major stream, for example, a river.
About 30% of the earth's land suffers from draught and that number could rise to 45% by 2059. 1.2 billion people lack access to clean water, and that number could rise to 3 billion by 2025.
50 percentAs much as 50 percent of the water we use outdoors is lost due to wind, evaporation, and runoff caused by inefficient irrigation methods and systems. A household with an automatic landscape irrigation system that isn't properly maintained and operated can waste up to 25,000 gallons of water annually.
