What Is Sprinkler System? What Are the Main Types of Sprinkler Systems?

A sprinkler system is a network of pipes, valves, and sprinkler heads designed to distribute water over a designated area for irrigation. It’s designed to provide efficient and even distribution of water to ensure that the designated area receives adequate moisture.

The system is typically connected to a water source, such as a water supply line or a well, and is controlled by a timer or an automated controller. In irrigation system design, sprinklers are used to deliver water to lawns, gardens, agricultural fields, and other landscaped areas. Here are a few ty[es that are commonly used.

Types Introduction Application
Misting Sprinkler A misting sprinkler sprays water in the form of fine droplets and is commonly used in scenarios that require a high level of water delicacy. Gardens, greenhouses, and areas that require fine misting for plants.
Drip Irrigation Drip irrigation releases small amounts of water directly to the plant’s roots for precise irrigation. It is suitable for plants that require controlled soil moisture. Vegetable fields, orchards, areas that require precise targeted irrigation.
Pulse Sprinkler A pulse sprinkler releases water in pulses and is commonly used in agricultural fields or large gardens to provide appropriate water volume and frequency. Orchards, large agricultural fields, and areas that require timed irrigation.
Subsurface Irrigation Subsurface irrigation is suitable for arid regions without conventional irrigation systems. It supplies water to plant roots through underground pipes and helps plants grow in water-limited environments. Arid regions, areas lacking irrigation infrastructure.
Rotating Sprinkler A sprinkler sprays water by rotating to cover a larger area. It is commonly used for large lawns or garden irrigation systems. Large lawns, gardens, and landscape areas.
Fixed Sprinkler A fixed sprinkler remains stationary and is suitable for areas that require targeted irrigation. Flower beds, specific plant areas, border irrigation.
Half-Circle/Full-Circle Sprinkler These types of sprinklers allow adjusting the water spray range as needed and are commonly used in areas with regular shapes to ensure full coverage of the designated area. Flower beds, courtyards, and areas that require targeted irrigation.
Adjustable Sprinkler Adjustable sprinklers allow people to adjust the water spray range and angle as needed with greater flexibility. They are suitable for various shapes and sizes of areas. Diverse gardens, yards, and areas that require customized irrigation.
Multiple Flow Sprinkler Multiple flow sprinklers have adjustable flow rates and are suitable for different water needs of various plants. Water flow can be adjusted based on the specific requirements of plants. Planting areas with diverse water requirements, areas that need to accommodate different plant needs.


Step-by-Step Guide on Sprinkler System Design

When it comes to designing a sprinkler system, there is a lot of work to undertake. Moreover, you should pay attention to the CAD importance in civil engineering. In some steps, using a CAD tool makes it easy for you to get things done. Now, let’s check out this sprinkler system design guide.


Step 1. Understand Plant Watering Needs for Efficient Irrigation

Determine the water requirements of the plants in your landscape. Consider factors such as plant type, growth stage, soil type, and local climate conditions. Some plants may require more water, while others may require less.


Step 2. Define Irrigation Zones for Optimal Water Distribution

Divide your landscape into irrigation zones based on plant water requirements and sun exposure. If necessary, divide the system into different zones, each with different irrigation requirements. Create a map or sketch to better understand the irrigation needs. This helps better control water usage, prevent waste, and improve efficiency.


Step 3. Consider Water Source and Pressure Management

Determine the water source for your sprinkler system, such as water, well water, or a water pump. Assess the available water pressure and flow rate to ensure proper functioning of the system.


Step 4. Select the Right Sprinkler Head Types for Effective Watering

Choose sprinkler head types based on the specific needs of each irrigation zone. Consider factors such as coverage area, precipitation rate, and adjustable features to meet the requirements of different plantings.


Step 5. Strategize Layout and Precise Placement of Sprinkler Heads

Use irrigation design software to create a sprinkler design layout. Then, plan the layout of sprinkler heads to maximize water distribution and minimize overspray or dry spots. Ensure proper head-to-head coverage by spacing the sprinklers appropriately.


Step 6. Install Main Controller and Valves for System Precision

Install a main controller that allows you to program watering schedules for each irrigation zone. Use valves to control the water flow to each zone for precise and efficient operation. Use valve boxes to protect the valves and ensure the system remains tidy when not in use.


Step 7. Execute Testing and Fine-Tuning for Seamless Operation

Test the sprinkler system thoroughly after installation to check for leaks, proper coverage, and adequate water pressure. Make any necessary adjustments, such as repositioning sprinkler heads or adjusting watering schedules, to achieve optimal performance.

FAQs About Sprinkler System Design

How Do I Calculate How Many Sprinklers I Need?

You can follow the steps below to calculate how many sprinklers will be needed.

  1. Measure the length and width of the area to be irrigated.
  2. Consider the types of plants and their water requirements.
  3. Find information on the water requirements for the plants, and determine how much water is needed per square foot (or square meter).
  4. Measure the available water pressure and flow rate using pressure gauges and flow meters connected to the water source.
  5. Select the appropriate type and model of sprinkler heads.
  6. Use the basic formula to calculate the number of sprinkler heads required:

Number of sprinkler heads = (Total area x Water requirement per unit area)/(Flow rate per sprinkler head x Efficiency of the sprinkler head)


What Is the Formula for Irrigation Calculation?

The general formula is (width of your yard x length of your yard)*0.623.

You can calculate water use by multiplying the width and length of your yard in feet to get the number of square feet. Then, multiply the square footage by 0.623 (suitable for a typical lawn ) to determine the number of gallons used.

Note: Different plants have different water requirements.



Sprinkler system design is quite difficult. It involves considering various factors such as the size and shape of the area to be irrigated, the water requirements of the plants, the water pressure available, and the type of sprinklers to be used. With a great helper like ZWCAD, you can make everything easier.
