But how do you choose the right one for your lawn? To make your irrigation system selection process easier, here’re a few kinds of irrigation systems, their benefits, and costs. 

  • Traditional Surface Irrigation System

Surface irrigation is one of the traditional irrigation systems. If you’ve got a large lawn area, then surface irrigation might be helpful for you. In this surface irrigation, the water is sprayed out from the spray head. 

This irrigation system covers a wide range of lawns at one go. The only loophole of surface irrigation is the lack of effectiveness. As the water shoots out in random directions, there’s no assurance that all parts of the lawn get an equal amount of water. However, if the irrigation system is fixed strategically, the surface irrigation system is a boon. 

Surface Irrigation System Cost: $6,000 to $8,000 per acre

  • Furrow Irrigation System 

If you’re looking for an inexpensive irrigation system, add furrow irrigation type to your list. As this irrigation system requires less pumping, the cost lies in between $700 to $1,000. The furrow system supplies water to the entire field effectively. 

Usually, a few sloppy channels are made in between the fields. The gravity supplies them by carrying down the slope and supports deep penetration of the water. 

Furrow Irrigation System Cost: $750 to $1,000 per acre

  • Rotor Irrigation System 

Rotor irrigation systems are a bit similar to the old-fashioned irrigation systems. However, it’s highly efficient in penetrating water deep into the soil. It supplies enough water to every part of the field and supports lush lawns. 

The rotor system covers the entire lawn and uses less water. Moreover, the rotor irrigation cost is less than the traditional irrigation cost. 

Rotor Irrigation System Cost: $1,000 to $1,500 per acre

  • Drip Sprinkler Irrigation System

Drip irrigation is one of the effective ways to supply water to the garden or lawn. As its name suggests, less amount of water is provided in a specific area. That’s why the drip sprinkler irrigation system is also known as micro sprays. 

In this system, few drops of water are sprinkled over a particular area. However, it seeps deep into the land and reaches the roots of the plants. If you’re residing in a water scarcity region, a drip sprinkler irrigation system is the best choice. The water quickly penetrates deep into the soil and supports rapid plant growth. Moreover, it’s one of the cheapest irrigation systems.

Factors affecting the Cost of Irrigation Systems 

The cost is not a fixed number. It varies based upon several factors such as the size of the land, landscape, climatic conditions, plant types, and many more. To estimate the appropriate irrigation system cost, you should understand the factors affecting irrigation system prices. 

Factors affecting the Cost of Irrigation Systems

Here’re a few factors that influence irrigation costs.

  • Water Sources for the Lawn/Garden/Land

The size of the water source majorly influences the irrigation costs. Usually, the houses in older areas have an inadequate water supply. So, installing irrigation systems in older homes or land consumes time and energy. Hence, the irrigation cost rises to the peaks. 

For instance, new residential houses consist of a water supply of ¾“. In contrast, the older homes typically supply water up to ½“. The land with less water supply needs more water zones to provide water to the entire land. 

Apart from the water zones, it additionally requires booster pumps at an additional cost. In this way, the water sources play a crucial role in influencing irrigation costs.

  • Landscape 

After water sources, here comes the landscape. Each land has its unique set of features and differs from other land areas incredibly. The grassy, flat, and smooth terrain requires no heavy-duty. 

So, the irrigation system costs are inexpensive. However, if you’ve rugged, uneven sidewalks, and concrete rocks, the irrigation costs skyrocket. However, it’s worth it. The irrigation system team has to transform rough and uneven land into a favorable irrigation landscape.  

  • Micro-climatic Conditions 

Do you know that different parts of land require different amounts of water? So, it’s essential to understand the micro-climatic zones in your garden or lawn. Though the entire lawn seems to be the same, different areas require different quantities of water. It’s known as microclimates. If your garden has a large number of microclimate zones, the irrigation costs automatically run up. 

  • Slope 

The slope is another factor that affects irrigation costs. The irrigation systems installation in the heavy slope areas costs more. The high slopes need to be trenched and made flat for adequate water supply to the entire land. 

If you’re living in high-slope regions, the irrigation costs increase. Before installing an irrigation system, discuss with the irrigation team and prepare an action plan based on the landscape conditions. 

  • Plant Types 

The types of plants also affect the irrigation costs. But how? Usually, the flowering plants and foreign breeds need more care and require a vast water supply. In contrast, the native plants require no extensive care and grow with the least water supply. 

Observe which plants do you grow in the lawn or garden. If you’ve more vegetable beds, you require more irrigation facilities. Also, the irrigation cost increases. If you’ve native plants, cool them. You can make a kush garden with less water supply at an affordable price.

  • Types of Irrigation System  

As discussed earlier, the different irrigation systems have varied costs depending upon the installation process. Choose the irrigation system based on the lawn irrigation requirements. If you’re looking for a minor budget irrigation system, drip and sprinkler are your evergreen choice. If you need a vast water supply, go for either furrow or rotor irrigation systems.

  • Soil Type 

Usually, clay or moist soils work best for gardening. But if you’ve rocky or sandy soils, it adds up an extra cost. The rocky soil and unstable sandy soil sucks time and energy. Stabilizing these soils needs extra work, equipment, and time. Simultaneously, the cost also increases.

  • Underground Obstacles

The obstacles like pipes drains, tree roots and massive rocks disturb the smooth flow of irrigation system installation. Moreover, removing these obstacles requires more labor, work, and time to influence the irrigation system cost greatly.  

So, these are a few factors that influence the cost of the irrigation system. However, consulting a pro irrigation installation team guides you and lessens the budget burden.

Calculate Your Irrigation System Cost 

With rising water and irrigation system installation prices, it’s inevitable to calculate the total water usage and its costs. But how do you calculate water usage? Here’s a complete process on how to calculate water usage and its cost on your lawn or garden.

Calculating Usage of Water and its Costs

In general, the lawn requires one inch of water per week in dry climatic conditions. You can calculate the water usage for your property using the ruler and a cup with vertical sides. 

Place the cup on the ground. Water the lawn either morning or evening for a week. Then, take a ruler or scale and measure the depth of the water in the cup. 

If the depth of the water is more than an inch, try to reduce the water supply. If the water depth in the cup is less than an inch, increase the water supply for effective grass growth. 

Now, let’s calculate the water usage. 

  • Imagine your lawn in rectangular or square shape. Note down the width and length of the property.
  • To calculate the water usage, initially, multiply the width and length of the lawn in feet. Then, again multiply the figure by 0.623
  • In general, a lawn with an inch of water requires around 0.623 gallons of water per square foot. 
  • So, for 10‘ * 10‘, the required amount of water is 62 gallons. For 100‘ * 100‘, the necessary amount of water is 6230 gallons

If your lawn is in a complex shape, then it’s time to pull out a geometry book to calculate the lawn area. Now, it’\s your time to calculate the lawn area. 

After calculating the lawn area, go for calculating water costs. 

You’re clear with the water usage in your lawn. If you aren’t clear with your property’s water use, it’s a bit of a complicated job to calculate the water cost. Usually, the irrigation system costs are based upon the gallons of water that you use. So, let’s calculate the water cost.

Calculating the Water Costs 

Usually, the irrigation costs include the water that you use along with the sewerage costs. If you use 2,000 gallons of water, you’ll be charged for both 2000 gallons of water and 2,000 gallons of sewerage.

However, if your city waives the sewerage costs, you’re lucky to save enough money. Or else, you must pay for both water and sewerage costs. 

  • For calculating water costs, divide the number of gallons of water that you use by 1,000
  • After that, multiply the result with the cost(water and sewerage cost) that you pay per 1,000 gallons of water. 

That’s it. Take a pen and a paper. Figure out your irrigation system cost. However, the irrigation costs also include several other factors, as mentioned earlier. But this calculation gives you a rough idea of irrigation costs. 


I hope you enjoyed learning a lot about the cost of the irrigation systems, including factors affecting irrigation costs, how to calculate, type of irrigation systems

Choose the appropriate irrigation system based on the requirements of your lawn. Then, consider all the factors influencing the irrigation system cost. Though the irrigation system seems expensive, it is worth it.
