Installing Your Own Automatic Irrigation System
Gardening is the number one hobby in the United States. Americans want their lawns and gardens to look good and for them to look good they need to be watered regularly and properly. Vegetable gardens, lawns and landscape plantings all have different watering needs. Most gardeners would prefer to spend their time gardening instead of watering the garden. Installing an automatic irrigation system to water for you can free up your time to spend on other things.
A drip irrigation system is relatively easy to install yourself. With drip irrigation you are applying water directly to the soil slowly. Drip irrigation is much more efficient than sprinkler irrigation because you are applying the water directly to the soil. It isn’t evaporating on its way to the soil nor is it running off the soil and you are putting it only where you need it, on the roots. You need a backflow valve to make sure the water doesn’t flow back into the house, a pressure regulator, a filter, a tubing adapter and the drip tubing and that’s it.
A sprinkler irrigation system on the other hand is a lot more involved and most people will hire a professional. For a sprinkler system to work properly it needs two things: water flow and water pressure. All the water flow in the world won’t help you at the sprinkler where it comes out if you don’t have enough water pressure. The pressure is what moves the water through the pipes and there has to be enough left once the water gets to the sprinkler for it to operate properly. The right size pipes, valves and other parts must be used to adequately control the amount of pressure that is lost in the system before the water gets to the sprinkler itself. Getting all of this right requires a lot of calculations and knowledge of PSI (pressure per square inch) so it can get a little technical for a lot of people.
You start by measuring your yard and sketching the area you want to irrigate. You then need to determine an initial flow rate which is basically the rate the water flows through the valve. Once you know the flow rate you need to look at all of the things that will use your water pressure as it moves from the valve to the sprinklers and how much pressure each of these things uses to determine the actual water flow and pressure values you will need to use for the system. You then draw the irrigation system on paper dividing it up into zones and laying out the piping routes and finally determine the size of each pipe to be used. You are now ready to start digging and installing your project. It is complicated and a lot of work just in the planning let alone the building. The average cost of professionally installing an automatic sprinkler irrigation system is between $2500 and $3000.
