4 Today s Goals What is the purpose of a Professionally Installed Irrigation System? What are the Benefits? How do they work? What are they comprised of? What are the available irrigation components that can be installed to conserve and reduce landscape water use while still providing the water the landscape needs too survive and thrive? 4

5 Best Management Practices (BMP s) A Best Management Practice (BMP) is a recommended practice. For the irrigation industry, the practices are defined below as a guide to reduce water usage and protect water quality. BMPs for irrigation systems are economical, practical and sustainable approaches to maintain healthy and functional landscapes without exceeding the water requirements of the landscape. 5

6 What is the purpose of a Professionally Installed Irrigation System? BMP 1 - Assure Overall Quality of the Irrigation System The purpose of an irrigation system is to provide supplemental water when rainfall is not sufficient to maintain the turf and landscape for its intended purpose. A quality irrigation system and its proper management are required to distribute supplemental water in a way that adequately maintain plant health while conserving and protecting water resources and the environment. Assuring the overall quality of the system requires attention to system design, installation, maintenance and management, in particular: The irrigation system shall be designed to be efficient and to uniformly distribute the water. The irrigation system shall be installed according to the industry design specifications. The irrigation system shall be regularly maintained to preserve the integrity of the design and to sustain efficient operation. The irrigation schedule shall be managed to maintain a healthy and functional landscape with the minimum required amount of water. 6

7 Best Management Practices (BMP s) BMP 2 - Design the Irrigation System for the Efficient and Uniform Distribution of Water. The irrigation system shall be designed to be efficient and to uniformly distribute the water. Specific criteria that shall be considered in the design include soil type, slope, root depth, plant materials, microclimates, weather conditions and water source (e.g., quantity, quality and pressure). To conserve and protect water resources, the design shall incorporate the appropriate equipment components that meet state and local codes and site requirements. 7

8 Best Management Practices (BMP s) BMP 3 - Install the Irrigation System to Meet the Design Criteria The irrigation system shall be installed according to the design specifications. To conserve and protect water resources, the installed components shall meet the design specifications, manufacturer s specifications, and state and local code requirements. The installation shall result in an efficient and uniform distribution of the water. The irrigation contractor or installer shall be licensed (and certified where applicable) and insured. 8

9 Best Management Practices (BMP s) BMP 4 - Maintain the Irrigation System for Optimum Performance The irrigation system shall be regularly serviced to maintain the performance of the system as designed. To conserve and protect water resources and the environment, the serviced components shall meet the design specifications, manufacturer s specifications, and state and local code requirements. The maintenance shall result in sustaining an efficient and uniform distribution of the water. The maintenance contractor, owner, manager, or irrigation contractor shall be licensed and/or certified (where applicable) and insured. 9

10 Best Management Practices (BMP s) BMP 5 - Manage the Irrigation System to Respond to the Changing Requirement for Water in the Landscape To conserve and protect water resources and the environment, the irrigation schedule shall be changed as required to provide supplemental water to maintain a functional and healthy turf and landscape with the minimum required amount of water. 10

11 Best Management Practices (BMP s) The BMPs defined above are based on the Irrigation Association s Turf and Landscape Irrigation Best Management Practices of December

12 What are the Benefits? The purpose of an irrigation system is to provide supplemental water when rainfall is not sufficient to maintain the turf and landscape for its intended purpose. A quality irrigation system and its proper management are required to distribute supplemental water in a way that adequately maintain plant health while conserving and protecting water resources and the environment. Efficient Application of water Smart controllers only apply what the landscape needs, thereby reducing water waste 12

14 GUIDELINES FOR EFFICIENT OPERATION OF AUTOMATIC UNDERGROUND IRRIGATION SYSTEMS The programming and operation of your automatic underground irrigation system will be dictated by a variety of factors. Your automatic controller should have all the required features to allow you to fine tune your system s performance for maximum efficiency. The following factors should be taken into consideration when programming your timers / controllers: 1. Time of year as well as past, current and future weather conditions. Conservation bylaws set by the town and current stages of watering bans. 2. Type of landscape material being watered. Lawns, shrubs, flowers and trees all have different needs. 3. Type of equipment i.e., rotary head, spray (mist) head or drip tubing. All of these have different application rates and should be timed differently. 4. The profile of your landscape also should be considered. Sun exposure, hills and slopes, low areas as well as soil types (loam, clay, sand) all need to be accounted for when making your programming decisions. In dry conditions, lawns and flowers which have shallow root systems may need to be watered more frequently due to sandy soil conditions than trees and shrubs which have deeper root systems. Generally, you would water lawns and flowers for less time more often and trees and shrubs for longer times less frequently. 5. Your controller should be capable of independent timing and scheduling of each zone in your system. Each zone should represent a specific part of your landscape i.e., front lawn, back lawn, back bed, etc. Each zone should be programmed in accordance with the aforementioned criteria. 14

18 Smart Irrigation Controllers Definition of Smart Controller Smart controllers estimate or measure depletion of available plant soil moisture in order to operate an irrigation system, replenishing water as needed while minimizing excess water use. A properly programmed smart controller requires initial site specific set-up and will make irrigation schedule adjustments, including run times and required cycles, throughout the irrigation season without human intervention. Testing of Smart Controllers IA test performance reports for smart controllers are a record of the water applied by a properly installed and programmed smart controller without human intervention for a testing period that receives a minimum ET of 2.5 inches and a minimum rainfall of 0.4 inches. Use of Smart Controllers For best results when using a smart controller, incorporate proper hydraulic design and equipment layout in the irrigation system installation. Initial monitoring of the site is necessary to confirm the accuracy of the irrigation schedule. Maintenance issues and site modifications may require irrigation system repair or recalibration of the smart controller settings to optimize system performance. IA 8/06/

25 Weathermatic Smartline Smart Controller The Basic mode programs exactly like the conventional controllers used by most manufacturers. There s no need to learn a new method. The Smart mode is where the power lies. Combined with our SLW Series Weather Stations, SmartLine becomes an ET-Based water-saving controller that adjusts watering times 365 days a year. ET Watering adjusts the duration, frequency, and soak time by several factors. Weather Data combined with geographical location, sprinkler type, plant type, soil type, and a fine tuning option, enables your SmartLine controller to make precise watering decisions. 25
