The Intelligent Use of Water ™ and You Reflects an environmental consciousness approach to promoting Irrigation… Can save Contractors and End-users money related to initial installation, replacement equipment and Water volume / use. Promote healthier landscapes Carrying / promoting this message will keep your customers coming back to John Deere…
The World’s Water Crisis There is no new water.
Current Water Issues The cost of water & power is rising annually As the population grows, limited water sources strain to keep up with demand = DROUGHT Metropolitan 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
Part 2 Issues Contributing to Poor System Expenses
Irrigation Overspray Runoff, Over-Scheduling Applying the water to saturation point
High Pressure Waste and poor coverage due to drift & evaporation
Wind Intrusion Bad Installation High trajectory — water drift and poor DU
Low Head Drainage Water waste, potential liability
Poor Central Control System Maintenance and Operation
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 fertilizer –Causes fungus and attracts pests –Major cause of plant death –Adds additional time and labor to maintain site –Water runoff can damage hardscapes and be an expensive liability –Poor public relations = not doing your part to contribute to this conservation effort and world-wide supply issue.
Part 3 Answer… Water Conserving products that save you money!
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.
Xerigation ™ aka Drip Irrigation
Water plants at the root, (no water loss by over-spray & evaporation) Irrigate the plant roots and not the ground between Low flow products = slower application & more infiltration Device flow rates are measured in GPH vs. GPM –Low flow rate equates to reduced erosion & runoff –Low flow rate means more emission devices per valve Operating pressure window is typically PSI Water is typically filtered to mesh
Spray Bodies (1800 & RD1800) and Nozzles
14 feet Low head without SAM wastes water. Spray Body-1800 SAM Series Built-in SAM check valve saves water and prevents erosion from low-head drainage.
Spray Body 1800/1800RD PRS Series PRS ensures optimal nozzle performance at 30 PSI in high pressure system Eliminates fogging & misting Reduces costly accidents and property damage Restricts water loss by 70% if the nozzle is damaged or removed Documented water savings of up to 50% –Reduces water usage by 6-8% every 5 psi reduction.
MPRVANU-Series Fixed Arcs Quality & Selection Adjustable Arc Versatile & Convenient U = Under Cut Dual Orifice Design High Uniformity 5', 8', 10', 12', 15' & Specialty Series 4', 6', 8', 10', 12', 15' & 18' Series 8', 10', 12' & 15' Series Spray Nozzles
Root Watering Series (RWS) Draws roots deeper –Promotes tree survivability –Right sized for trees and shrubs Minimizes water required for growth –Helps properties comply with restricted watering Point source irrigation via drip and/or turf watering devices Preserves hardscapes –Aesthetically pleasing –Helps minimize personal injury –Minimizes run-off for the entire zone Pre-assembled for quick installation and efficient operation
Large Water Droplets –Larger water droplets are more wind resistant. –Assures that the water is delivered to the desire location. –A better design for “real world” conditions. 7005/8005 Series Brand H I40 Rain Curtain ™ Technology
5000 Series Hunter PGP Rain Curtain ™ Technology Even Distribution / Close in Water –Avoids over-watering due to poor nozzle performance. –Eliminates the need to use the “break-up” screw to create good coverage. – A better design for “real world” conditions.
5000/5000 Plus PRS Series What is it? –PRS – Pressure Regulating Stem similar to the 1800 (PRS). –ONLY ROTOR TO HAVE THIS –Rotor throwing 25' to 50' What does it do? –“Plus” = rotor manual shut-off tab to shut off head even when valve is operating –In-stem pressure regulation reduces inlet pressure to 45psi for optimal nozzle performance. Save Water with PRS and Plus
5000 MPR Nozzle Sets MPR Rain Curtain nozzles for 5000 & 5000PLUS rotors 25', 30' & 35' radius trees Combine Q, T, H & F nozzle arc patterns on one valve True matched precipitation rates between arc patterns & nozzles trees radii
