The Irrigation Situation Keeping Your Landscape Green

 One of the things that attracts people to a condo or HOA are the beautiful  grounds and lush landscaping that surrounds the property. Because of the  topography of the Chicagoland area, depending on where a home is located, water  could be plentiful or the area could be drought-stricken. It’s almost always necessary for properties to use irrigation technology to keep  their lawns, trees and shrubs healthy and green.  

 Anyone who has ever lived in a condo has probably seen the sprinklers go on and  off, and while you may not think it’s that big of a deal, using the proper system and controlling water levels for  all areas of the property can be a challenge. In the past, associations may  have relied strictly on sprinkler systems or gardeners who would water the  property with hoses, but irrigation systems have come a long way and today’s watering technology is cheaper, greener and much more sophisticated. Long gone  are the days when installers would drop pipe haphazardly into the ground  figuring that spraying around large volumes of water would make up for a  hit-or-miss installation.  

 New and Improved

 Irrigation controllers have become extremely sophisticated, going as far as  adding computer technology to improve its timing and diagnostics. Unfortunately  for landscapers, this doesn’t end the need to connect the controller to every valve with a bundle of  dedicated buried wire.  

 The programmable valve is another innovation that uses no electricity and is  being sampled by some area landscapers. The valve can be programmed to open and  close in any combination of settings based on a cycle of every seven times the  water is turned on. It is small enough to be installed under a sprinkler head,  or in another version, can be used in a water line. This innovation means that  each sprinkler head can be programmed to open at different times than the  others in the same zone.  

 Materials have also changed a lot in recent years, with newer type heads  designed to last longer. Spray head sprinklers are designed for more durability  and uniform watering and are ideal for lawns, flowerbeds, and shrubs.  Meanwhile, new plastic valves are constructed for reliability and are easy to  install for a multi-valve system.  

 “Recent innovations in irrigation use less water more effectively,” Dennis Fiddick, the commercial account manager for DRF Total Property Solutions  in Chicago, says. “MP rotary is an example of a low-flow sprinkler head that covers the same area  as a lot of other types of heads, but at a much lower rate of water. So that  means you can effectively cover areas using less water, and have more control  over it. If you irrigate at a high rate, you lose control, and a lot of that  water will just run down the road and into the storm sewer, as opposed to  sinking into the ground, in the soil. So these systems are moving to a much  slower rate of irrigation which allows you more control and less runoff. And  that's a concept that's kind of spreading through the entire irrigation  industry right now,” Fiddick says.  

 Water Conservation

 “Last year the city of Chicago, in an effort to try to figure out how to solve  their budget problems, decided to raise the price of water in a four year  structured increase that will double the cost of water from 2012 to 2016,” Fiddick explains. According to Mayor Rahm Emanuel’s 2012 budget proposal, the rate of water went from $2.01 per 1,000 gallons to  $2.51 per 1,000 gallons in 2012. “The 2013 rate will be $2.89; 2014 will be $3.32; and 2015 will be $3.82,” as per the city’s website at www.cityofchicago.org.  

 “The reason that helps solve Chicago's budget problem is because most of the  suburbs use city of Chicago water. All the people that have irrigation systems  are now really interested in what kind of controls they can put on their  irrigation systems that will make sure they’re not over-watering.”  

 According to Fiddick, this water price hike has really inspired associations to  employ smart water technology. “To be honest with you, this area here around the Great Lakes is probably one of  the last areas to really take the water conservation thing seriously. There's  such an abundance of fresh water here. With Lake Michigan sitting there, no one  really sees the water issues that a lot of the other parts of the country have.  They don't rely on water from wells like the other parts of the country do.  They're getting the water right from Lake Michigan. So, to be honest with you,  it's taken something like this price increase to wake everybody up around here  and say, ‘Whoa, wait a second, am I wasting water?’ And the answer in most cases is ‘Yes.’ Fiddick says.  

 Plant choice is as equally important when in comes to water conservation as the  logistics of the irrigations system, according to John Alexander, the field  supervisor for Christy Webber Landscapes in Chicago.  

 “If people select plant material that is adapted to our climate, then irrigation  would only be needed minimally to sustain plants during drought conditions,” Alexander says. Plants have numerous benefits to our environment through storm  water management, air quality benefits, CO2 reduction and depending on their  placement in the landscape they can benefit households in electric savings by  providing shade.”  

 Irrigation by Season

 An irrigation contractor will do more than just put in sprinkler heads and  clocks; they will work with you throughout the year to ensure the landscaping  is looking its best at all times. Fiddick says it’s important to plan all year as each season requires checks to the system. “In the Midwest, irrigation systems are seasonally operated. They usually are  turned on sometime after April 1st and then they are winterized sometime  between October 15th and November 15th.”  

 As of January 1, 2008, all irrigation systems in Illinois must be equipped with  moisture or rainfall technology. “Irrigation systems need to be equipped with some sort of sensors and equipment  that can read rainfall and heat, so that they self-adjust,” Fiddick says. “The system has the ability to sense what the weather is and change accordingly,  raise or lower the watering times based on what the weather conditions are.”  

 In the spring, all drain valves and plugs are closed to look for any leaks in  the system. Each individual zone is checked and all heads are cleaned and  adjusted to maximize proper efficiency. Once everything is done, the system is  reset for proper zone coverage and the control time is reset for optimal spring  watering needs.  

 When the cold weather comes around, valves and drains are shut off and  compressed air is pumped into the main lines, valves and heads to ensure the  system is completely water free and prevents breakage of frozen pipes and  valves, Fiddick says.  

 Licensed and Insured

 Before hiring someone to fill your irrigation needs, a condo or HOA should make  sure that the company is licensed and insured and has met the irrigation  guidelines of Illinois, experts stress.  

 “When HOA’s are selecting a landscaper, they should make sure the provider understands the  plant material water requirements in relation to the irrigation settings. In  other words, don’t just set the irrigation to run and walk away. That’s a recipe for disaster—proper monitoring is key. The landscape provider should be able to spot signs of  stress due to over-watering and under-watering,” Alexander says.  

 According to Chapter 111 par. 1102 of the Illinois Plumbing Licensing Law, “Every irrigation contractor must provide proof that he or she is a certified  irrigation contractor or certified irrigation designer.”  

 “I would suggest that the first thing they do is make sure the irrigation  contractor they choose is a certified irrigation contractor through the  Irrigation Association,” Fiddick says. “That's a worldwide organization that has certification and education  classifications. You want to make sure the contractor you're choosing has the  knowledge to design the system using the appropriate equipment, and is  designing an efficient irrigation system. Otherwise, your poor choice in a  contractor that doesn't have this design knowledge will result in you spending  way more on water costs than you should,” he warns.  

 To find a certified irrigation contractor near you, visit the Illinois Landscape  Contractors Association at www.ilca.net or the Irrigation Association at  www.irrigation.org.  

 No one should take their landscaping for granted and for a condo or HOA who  wants to attract more people, they should really look into upgrading its  irrigation system.  

 That way your grass is sure to be greener on your side of the fence.
