The identification of fixed spray and rotor as the two basic types of sprinklers used in irrigation systems is grounded in their distinct operational functionalities and applications within landscape irrigation.

Fixed spray sprinklers are designed to deliver water over a defined area in a specific pattern and are typically employed in smaller areas where uniform coverage is needed, such as gardens and flower beds. Their ability to provide a constant spray radius makes them highly effective for uniform water distribution on level surfaces.

On the other hand, rotor sprinklers utilize a rotating nozzle to discharge water in a larger and more controlled pattern. This type of sprinkler is well-suited for lawns and larger areas, capable of covering vast expanses efficiently. They operate at lower flow rates than fixed spray sprinklers and can be adjustable, providing flexibility in irrigation design.

The combination of fixed spray and rotor sprinklers in irrigation design allows for effective coverage tailored to the specific needs of various landscape features, ensuring adequate water distribution and promoting healthy plant growth. Understanding these two types is essential for successful irrigation planning and management.
