Tips on Irrigation Design for Landscape and Gardening

No landscape or garden is complete without a proper irrigation design system and a certain amount of planning is required to implement a system that is both cost event and contributes to water conservation initiatives.

Today most everyone has jumped on the green bandwagon trying to further conservation efforts in order to decrease their footprint on our planet.

One way that garden enthusiasts can make a considerable mark is by planning an irrigation system that supports green initiatives. What are some tips on irrigation design that will help you conserve water?

Necessary Equipment for Irrigation Design

With the variety of products, equipment, and accessories it may be hard to decide where to start. There are several factors to consider before you get started.

These factors include the type of plants and greenery that you are nursing whether vegetable plants, grass, shrubs, hedges or flowering plants. Each of these types of plants has sub-categories and these subcategories have specific irrigation needs.

For example, shrubs and hedges are especially resilient and therefore do not require much water while certain perennials require both a considerable amount of sunlight and water. Knowing the plants that are in your garden or part of your landscape will contribute to designing the perfect type of irrigation system.

Irrigation Design and Methods

The first step to proper irrigation design is mapping out your garden or patch of greenery. Making a simple diagram of where your plants are and the types of plants that are there will help you to design a system that will provide the most efficient coverage and contribute to lush green and healthy plant growth.

Once you’ve completed your diagram you will be more equipped to decide on the best irrigation design because of this visual aid. A visual aid of your area will help in positioning tubing or piping along with determining the amount of water flow required to effectively cover your area.

After having accomplished this part of the planning stage now it’s time to move onto the next phase which includes weighing the benefits and disadvantages of a drip irrigation design versus a traditional sprinkler system.

While both systems have advantages and disadvantages the decision really lies in the individual needs of your green space.

Smaller gardens and landscape areas, for example, may be better suited for a drip irrigation system because the flow will be more concentrated directly at the root system creating a more moisture-rich environment that produces lush greenery.

In contrast, a larger area would do well with irrigation using the traditional sprinkler system that is modified to distribute a misting spray that provides a dew like an effect saturating the needed areas with minimal water waste. Whatever the case may be both systems are equally as effective depending on your needs.

So remember, taking an inventory of your garden or landscape area and researching your options will provide you with the best direction for designing an irrigation system that is environmentally friendly with the right and useful irrigation design.

How Garden Irrigation Systems Promote Water Conservation?

For many of us, a garden irrigation systems consist of a garden hose that we manually wheel around sprinkling as many plants as we can get and saturating our garden indiscriminately until we finally either tire under the weight of the water-filled hose or the blazing summer sun.

Some of us that are a little more sophisticated employ the use of a drip irrigation system to irrigate our garden. But we’ve all driven by those lawns that are saturated to the point of complete submersion leaking water in the street and onto the sidewalks. Well, let’s consider the advantages and disadvantages of each of those irrigation systems.

Traditional Garden Irrigation Systems

The first garden irrigation system that we’ve mentioned in the traditional sprinkler system. If you have the patience and know-how to install the piping, sprinkler heads and the timer then you’re doing great. This system can be both cost-effective and contribute to water conservation if used the right way.

What is the right way? Well, leaving your sprinkler system on to run at non-determined times until the garden is so saturated that the soil resembles a soup is definitely not the way to conserve water.

It can also contribute to diseases that are experienced by plants receiving an overabundance of moisture to their rootstock. In order for this method to work toward water conservation initiatives, you need to set your timer to water at precise times during the day when the chance of evaporation is lower meaning later on in the day when the sun is not so hot.

Also, it means placing the sprinkler heads in strategic places to sufficiently cover the garden while adjusting the heads so that the water comes out in a fine mist that will create a dew like an effect.

Drip Garden Irrigation Systems

The drip garden irrigation system is a system designed to sufficiently deliver water only a plant rootstock through a vented irrigation line that runs through your garden and trickles little drips of water slowly into the soil at just the right spot.

The potential for water conservation is extremely evident in this method of water delivery. This method makes water conservation easy and more efficient because it only delivers the water where it needs to go.

Because the holes in the tubing are so close to the ground there is little chance or evaporation as the water is delivered right to the source so to speak. There is less waste because of a better delivery system.

Whatever garden irrigation system that you choose should be based on the needs of your garden. Each method can be used to conserve water.

The former method just requires a little ingenuity, forethought and planning to conserve water but it is possible. Water conservation is a responsibility of us all. Therefore, installing garden irrigation systems should be taken into consideration seriously.

How do I Properly Install a Lawn Irrigation System?

Installing a traditional lawn irrigation system need not be a daunting task if only instructions are followed and the steps are planned carefully to ensure that you are setting up your system to the specifications of your particular garden or lawn.

The key is planning. If you take the time, in the beginning, to ensure that all of your specifications are met you will have an easier time in the end when the actual application is made and your system is engaged.

Modern Lawn Irrigation System

There is nothing more frustrating than completing a project only to find out that something is wrong with the installation and it doesn’t work. More often than not this failure can be attributed to a lack of proper planning.

In order to avoid this the first step therefore in installing your new lawn irrigation system should be to make a visual map of your space. That’s right, get out your pencil and make a sketch of your area with figures that represent the plants to show placement.

Having this visual aid will make it far easier to design your system concentrating the water flow in the areas that need it most. Be sure to make a note of any potential obstructions to a clear line to the faucet so that you can compensate for these without having to dig new holes. As you will see planning helps also to eliminate having to redo any steps later.

After your drawing is complete you can move on to testing your water pressure and flow rate. Why is this important?

Well knowing your water pressure and the flow rate is important in choosing the correct sprinkler heads that will pump the adequate amount of water to satisfy the needs of your plants while conserving as much water as possible.

The third step is to arrange your spray patterns. The spray patterns are the directional pattern in which the sprinkler heads will be arranged in the yard. This arrangement would include the type of sprinkler heads that will be needed to provide the optimum amount of coverage as well as the number of heads required.

It would be a smart idea to allow for at least a 50% overlap of each head to ensure that the essential parts of your lawn are covered.

The fourth step is to make a list of all the supplies that you will need. Make sure that your list is as complete as possible to avoid making multiple trips to the home improvement store. Be sure to make a list of any questions that you have so that these may be addressed with an expert at the store.

When your store adventure is over and you have all equipment in hand create a test model of your layout to ensure that you have all the piping you need prior to digging.

The Piping of Lawn Irrigation System

When you are satisfied that all the piping is there dig your trenches approximately 4 inches wide and 8 to 10 inches deep. Fit the pipes together and glue in place with an easy brush application primer.

When the glue is set attach the pipe to the water supply, attach the risers that will ensure proper positioning, flush the system ensuring that there are no obstructions and attach the sprinkler heads.

If you figured in a controller for your system you would install and program it now to ensure that the cycles correspond with any water restrictions being observed in your community.

The final step is to test your lawn irrigation system listening carefully for any unsecured pipe and observing to make sure that the water flow is even and covering the areas that require moisture.

Although this is a very intricate process it can be made considerably simpler by planning. If you plan from the start you will finish faster. The results will be successful and you will have a wonderful lawn irrigation system.

Drip Irrigation is one of the New Irrigation Methods

Drip irrigation is best used for irrigating vegetable and fruit crops because the ventilated piping can be placed between the furrows of the crops or event submerged under the earth along the root line to deliver a steady drip or trickle of water right to the source.

Either way, the majority of the water is absorbed directly into the root source and evaporation is virtually eliminated. This method of irrigation saves over a fourth of water and is relatively cheap as compared to other similar systems.

The traditional spray irrigation method is the preferred method for exhaustive fruit groves because it covers a lot more area. One very popular spray system is the center-pivot system. This system works much as the traditional spray irrigation system would work in a back yard.

Metal frames hold the water tubes which end in a water gun that sprays water over the lawn in concentrated bursts. The oscillating head provides even coverage of the area.

The only drawback is that the potential for water waste is considerable. However, there is a way to customize the spray using misting spray that will create more of a rain forest dew effect that will waste less water.

Overall this method requires more machinery to power it than the drip method but it seems to be a favorite of modern farmers among other irrigation methods.
