Sprinkler System And Irrigation Basics

Each small square on the graph paper should represent one square foot of actual property or use a scale such as 1 inch = 10 feet, 1 inch = 20 feet, etc. Using a tape measure, measure your property and draw it to scale on the layout paper. Use the drawing here as an example:

Drawing your home on graph paper.


  • Outline your house, garage and other structures.
  • Show walkways, drives, slabs, patios and other surfaces.
  • Identify trees and major obstacles.
  • Measure and record the perimeter of your property.
  • Identify slopes.
  • Show groundcover, grass, flower beds and landscaping.
  • Identify the size and location of the water meter (or pump) and main line.
  • Identify the soil type in your yard.
  • Write the scale of your drawing on your information sheet!

The sketch you create is a scale drawing of your property and home, which will include trees, gardens, shrubs, raised planting beds, water sources such as streams and ponds, and the location of the home's main water supply line. Also sketched on your plan will be any patios, walkways, fences or structures that may block the path of your sprinklers and pipes. You sketch will also show any areas which have a slope of at least 10%. Unless your landscape is extremely small in size you will need more than one grouping of emitters or sprinkler for your plants. Each grouping is called a zone. The number of zones you will need will depend mainly on if you will use a sprinkler or a microirrigation system or both. A sprinkler system uses much more water. Some things to consider are the different watering requirements in your landscape design.

You will need to consider the following things to determine the amount of zones necessary to complete your plan:

Sun Vs. Shade

Sun vs. Shade

Water plants that are in the shade seperately from plants that are in the sun.

Trees And Shrubs

Trees and Shrubs

Plants such as trees and shrubs need infrequent but complete watering.

Annuals & Vegetables

Annuals & Vegetables

Annuals and vegetables need shallow and frequent watering.



Water plants in containers seperately because they tend to dry out more quickly.



If your landscape is large you can keep each area zoned seperately. If your landscape is small you can try to group plants that have similar but not identical needs together in one zone. For example, you could put your flower beds, hedges and ground cover in a zone.



Any area with a incline of more than 10% should be zoned seperately. Slopes require special planning to avoid unwanted runoff. A way around this is to create flat terraces held in place by retaining walls. Low precipitation devices set at the correct angles will be needed to irrigate a sloped area.

Special Needs

Special Needs

Some plants have special watering requirements. For example, roses should not have water on their leaves. If you have roses you may want to use a bubbler or microirrigation instead of a sprinkler. Plants that are drought tolerant can also be watered seperately.



Areas with turf have specific watering requirements and should be watered seperately.

It is important that your measurements are accurate. Precise measurements are needed for pipe and tubing, a deviation of a few feet can cause a problem. Measurements for plotting your sprinkler sprays and rotors must be even more precise. You will need a tape measure that can measure lengths of at least 50-100 feet.

Sprinkler System Lawn Drawing

To begin you will start by measuring your home's outside dimensions. Note all the measurements you take on a rough sketch. Next measure straight lines from each corner of your home to your property lines. Now note the dimensions on your intitial sketch as well as the width of any walkways or patios. Next mark the dimension and location of any leach fields or septic tanks. Next measure all the areas that you want to water, your flower beds, lawns, raised beds, patios and decks that have plants in containers.

Now indicate on your sketch the location in which you intend to tap into your home's water supply. Next mark where you intend to locate your controller/timer. Once all the measurements have been noted you can draw your plan to scale using graph paper. Each square will equal a specific amount of feet depending on the size of your landscape.

The next step is to add your water zones. Make a copy of your master irrigation plan. It's a good idea to color code your zones with a marker or colored pencil by circling them on your sketch. You may also want to note which areas have shade, bright sun, wind conditions and also areas that are not level. (See How to Measure a Slope for more information).

Sprinkler System Zone Drawing

Now that your sketch is complete you are ready to begin to layout your irrigation system. If you do not feel confident enough to complete your irrigation plan there are some stores that will layout an irrigation plan for free as along as you purchase your supplies from them. You can also hire an irrigation specialist for assisance. (Click here for a list of contractors in your area)
