9 The World’s Water Crisis Water seems to be the most abundant resource around…. but even though we live on a planet that is covered in water…… only a very small percentage of it is fresh water that people can use. Most is tied up in our oceans, or trapped in snow and icebergs.97% 2% / 1%…only about 10% of the total rainfall on earth is retrievable for use. Most flows into the oceans ….or falls in remote areas.5500 years ago - less than 10 million people.By 2030, 8 billion people. ….all relying on a finite water supply.Industrialization accelerates their consumption of water as well…….. a basic conflict: the global fresh water supply is fixed, but world population and water consumption continue to go up every year. In a nutshell, there is no new water.There is no new water.
10 Current Water Issues The cost of water & power is rising annually As the population grows, limited water sources strain to keep up with demand = DROUGHTMetropolitan water delivery systems are aged & designed to service a much smaller number of people than is required today = INFRASTRUCTURE IS STRAINED (Need to apply quickly and efficiently)Irrigation is one the most visible forms of water use and is usually the first to be regulated in a drought or water shortage condition. i.e… Indianapolis ‘12
11 And there are very few countries that have not been affected in some manner by a scarcity of water. Just look at the U.S. Drought monitor over the last few years. Virtually all regions of the US have been affected to some degree by drought.11
12 Issues Contributing to Poor System Expenses Part 2Issues Contributing to Poor System Expenses
13 Irrigation Overspray Runoff, Over-Scheduling Applying the water to saturation point
14 Waste and poor coverage due to drift & evaporation High PressureWaste and poor coverage due to drift & evaporation
15 High trajectory — water drift and poor DU Wind IntrusionBad InstallationHigh trajectory — water drift and poor DU
16 Water waste, potential liability Low Head DrainageWater waste, potential liability
17 Poor Central Control System Maintenance and Operation
18 The Cost of Wasted Water Over watering the landscape creates additional problems beyond the cost of the wasted water:Leaches nutrients from the root zone requiring the application of additional fertilizerCauses fungus and attracts pestsMajor cause of plant deathAdds additional time and labor to maintain siteWater runoff can damage hardscapes and be an expensive liabilityPoor public relations = not doing your part to contribute to this conservation effort and world-wide supply issue.

20 Product Terminology Precipitation Rate (PR) The PR is the average rate in inches per hour at which water is being applied to the area covered by a specific sprinkler layout.Distribution Uniformity (DU)The DU is a measurement of uniformity, expressed as a percentage, comparing the driest area to the average wet area. The more evenly water is applied = higher number; 100% is the best but does not exist!Scheduling Coefficient (SC)Scheduling coefficient is also a measurement of uniformity comparing the driest to the most wet areas but measured in terms of run time.
22 Xerigation™ aka Drip Irrigation Water plants at the root, (no water loss by over-spray & evaporation)Irrigate the plant roots and not the ground betweenLow flow products = slower application & more infiltrationDevice flow rates are measured in GPH vs. GPMLow flow rate equates to reduced erosion & runoffLow flow rate means more emission devices per valveOperating pressure window is typically PSIWater is typically filtered to mesh
25 Spray Body-1800 SAM SeriesBuilt-in SAM check valve saves water and prevents erosion from low-head drainage.14 feetLow head without SAM wastes water.
26 Spray Body 1800/1800RD PRS Series PRS ensures optimal nozzle performance at 30 PSI in high pressure systemEliminates fogging & mistingReduces costly accidents and property damageRestricts water loss by 70% if the nozzle is damaged or removedDocumented water savings of up to 50%Reduces water usage by 6-8% every 5 psi reduction.
28 Root Watering Series (RWS) Draws roots deeperPromotes tree survivabilityRight sized for trees and shrubsMinimizes water required for growthHelps properties comply with restricted wateringPoint source irrigation via drip and/or turf watering devicesPreserves hardscapesAesthetically pleasingHelps minimize personal injuryMinimizes run-off for the entire zonePre-assembled for quick installation and efficient operation
