How to select an underground irrigation system
June 11, 2011
Did you know ... watering your lawn for just one hour uses about as much water as...5 dishwasher loads, 5 loads of laundry AND 25 flushes of the toilet (1500 litres in total).
Most of us are facing increasingly more restrictive regulations for the watering of our lawns and gardens. And, now that many of us are on metered water and pay for what we use, we have an incentive to use this precious resource more responsibly.
Observing water restrictions means you have to be home at the right time, you have to be there throughout the watering process to move the hose and sprinklers around and you might have to ask a neighbour to help if you are away on vacation.
Many homeowners are choosing to have sprinkler systems installed to avoid all the hassles that come with watering your lawn and garden.
So you are considering an automatic underground sprinkler system for your home... Good Idea! With increasing demands on our time, and ever-present local concerns about water conservation, watering restrictions and a natural desire to increase property values through attractive landscaping, the current automatic underground sprinkler system has become a working member of an already busy family.
Irrigation systems have come a long way since manufacturers started making sprinklers in the 1930s. Manufacturers have been very efficient in responding to a growing need for water conservation as well as practicality.
There are several important questions to ask when considering the purchase of a sprinkler system:
Q. What is an automatic underground sprinkler system?
A. It is the finest man-made method of watering your garden available in the world today. Each system is specifically tailored to meet the irrigation needs of the individual homeowner. Major components of a typical residential sprinkler system will include:
A controller, either mechanical or solid state that functions as the brains of the system. Its responsibility is to store the watering schedule in its memory and to turn the system on and off automatically as the watering program indicates.
Valves, on command from the controller, open to release water through buried pipes to any of several different types of sprinklers.
Sprinklers, parts of the system that actually distribute the water to your lawn and garden areas, are available in a variety of sizes and shapes. Rotor pop-up heads distribute water up to 40 feet away; other pop-up spray heads (commonly called misters) that reach 2", 4" 6" and 12" above the ground, deliver water to a more localized area. Bubblers and drip emitters are ideal for watering small areas and single plants.
Q. What are the advantages of owning an automatic underground sprinkler system?
A. Saves time. Saves water. Saves plants. And yes, it is even a good financial investment. Let us look more closely at each of these reasons for installing a sprinkler system.
They can be set to the current local watering restrictions.
How many times have you forgotten the water running outside, only to remember an hour or more later and find that hundreds of gallons have drained onto the street, wasting a lot of water, a prized natural resource! All because you forgot to turn the water off! An automatic underground sprinkler system never forgets. It can save you literally thousands of gallons of water a year simply by remembering to turn itself off at the right time.
Most plants, like people, thrive on a steady, well-regulated schedule of nutrition. An automatic underground sprinkler system will provide your plants with a carefully timed, precisely measured amount of water, when they need it. You can count on it - they can, too!
The appearance of your home is an important factor in determining its market value. An automatic underground sprinkler system can help your house keep a fresh, well-maintained look. Lush growth, healthy plants and an attractively landscaped exterior tell the prospective buyer that your house has been cared for.
Owning an automatic underground sprinkler system means that the hours you are now spending watering your garden with a hose can be devoted to more enjoyable activities. Also, there is no longer a need to remember to move the hose every 20 minutes. Your new system will do all the remembering for you. It will turn the sprinklers on and off automatically, according to your instructions.
Q. I have an old sprinkler system. Can I upgrade it?
A. Yes you can. It is possible to add components to an existing irrigation system. Be sure to let your irrigation contractor know of any future additions to the system you may be planning. A properly designed irrigation system fully utilizes every drop of water, and to expand the system once it is installed may substantially reduce its efficiency.
Q. How will the system help me conserve water?
A. Excessive runoff from over-watering is a common problem experienced when using either a hose or a poorly designed and installed automatic system. Field studies have shown that a properly designed and programmed automatic underground sprinkler system is the most efficient method of watering your garden while using a minimum amount of water.
Q. Who will operate the sprinkler system while I am away on business or vacation?
A. The correct answer is THE SPRINKLER SYSTEM! Remember, your new AUTOMATIC system is designed to operate on a set schedule (your schedule), regardless of whether you are home or thousands of miles away on vacation. One of the real benefits of this type of system is that once it is programmed, it will continue to operate on schedule until you tell it to make a change.
Q. We have 50" of rainfall a year. Why do we need a sprinkler system?
A. You probably would not need a sprinkler system if it rained 1/2" of water every 3 1/2 days, without ever missing a day. Unfortunately, nature does not work that way and in many parts of the country receiving 50" of rain a year, there are long periods when NO rain falls. For healthy, lush plant growth, it is important that they receive an evenly measured, regularly timed application of water. In the blistering heat of summer, often as few as two days without water can be damaging to plant growth. And, if it does rain, your irrigation system can be equipped with a rain sensor that will tell the system to skip the watering session so it does not water when it is not required.
Q. How much will a new system cost?
A. Of course, the price will vary depending upon individual needs such as property size, special designs, and type of landscape, but you can rely on a qualified contractor to recommend the right system at the best possible price to suit your needs.
