Water is a priority United Nations Formed UN Water UN Water is an inter agency mechanism formally established in 2003
United Nations UN Water focuses on: Providing information Building the knowledge base Providing a platform for discussion and knowledge sharing
United Nations A coherent, coordinated approach is clearly required We must manage freshwater sustainably so that everyone has enough water to drink and stay clean and healthy Food producers must have enough water to satisfy the demands of growing populations
United Nations Industries have enough water to meet their needs Countries have opportunities to secure a reliable supply of energy Must be able to adapt to changes in the availability of freshwater Ensure public health and preserve ecosystems
Statistics How the world uses freshwater: About 70 % for irrigation About 22 % for industry About 8 % for domestic use Source: World Water Assessment Program (WWAP) Water use has been growing at more than twice the rate of population in the last century
Statistics The world's six billion people are appropriating 54 percent of all the accessible freshwater contained in rivers, lakes and underground aquifers. Source: WWAP How the world uses freshwater: Water withdrawals are predicted to increase by 50 percent by 2025 in developing countries, and 18 percent in developed countries. Source: Global Environment Outlook: environment for development (GEO 4)
Statistics In 60 percent of European cities with more than 100,000 people, groundwater is being used at a faster rate than it can be replenished. By 2025, nearly 2 billion people will be living in countries or regions with absolute water scarcity, and two thirds of the world population could be under stress conditions.

Water Measurement Water is measured in acre feet An acre foot is: 326,000 gallons of water Enough water to cover one acre to a depth of one foot A one year supply of water for two to three families of four
How Much Water Does Orange County Use? Imported Water = Colorado River Aqueduct State Water Project Transfers/Storage Local Sources = 328,000 AF 290,000 AF Groundwater Surface water (lakes, reservoirs) Recycled water = 50,000 AF Irrigation Groundwater Recharge (GWRS) Total Annual Demand = 668,000 AF Water Use efficiency = 30,700 AF and growing
The Reality Is Water rates will continue to increase New water quality standards New supply development New regulations are being implemented Water Conservation Ordinances Water Efficient Landscape Ordinances Plumbing fixture flow standards Irrigation equipment standards
Case Studies for Water Efficiency Amusement Park Luxury Hotel
How Can Amusement Parks Save Water? Where are the opportunities? Indoor Outdoor Are there other benefits to saving water? Electricity Natural gas Waste water Runoff reduction
Where are the opportunities Indoor? Toilets Dish washing Urinals Cooling Faucets Food steamers Ice machines Leak detection and repair
Where are the opportunities outdoors? Irrigation scheduling Smart irrigation timers Low precipitation irrigation technology Pressure regulation Plant materials Maintenance practices Irrigation management training Water brooms Leak detection and repair
Amusement Park Case Study Disneyland partnered with Anaheim Public Utilities Installed 50 SmarTimers scheduling for improved irrigation Saving 82 million gallons per year, a 20 percent savings Installed a water recycling system Recycled water is used for irrigation, water features, and maintenance Saving 5 million gallons per day, 25 percent of the resort s total water use
