Which type of sensor is mandatory for new irrigation systems?

A rain sensor is mandatory for new irrigation systems because it plays a crucial role in water conservation and efficient irrigation management. The primary function of a rain sensor is to detect precipitation and automatically shut off the irrigation system when it rains, thus preventing unnecessary watering. This not only conserves water resources but also reduces costs associated with overwatering, such as increased water bills and potential landscape damage.

Implementing rain sensors helps ensure that irrigation is only performed when needed, aligning with best practices in sustainable landscape management and environmental stewardship. This requirement reflects a broader trend in irrigation regulations aimed at promoting efficient water use and minimizing waste. By requiring rain sensors, the regulation supports the responsible use of water, especially in regions where water scarcity may be an issue.
