What is the purpose of a water-efficient landscape irrigation system outlined by CALGreen?

The purpose of a water-efficient landscape irrigation system as outlined by CALGreen is to reduce potable water use. This guideline is essential in promoting sustainable landscaping practices, especially in areas where water resources are limited. By implementing water-efficient systems, landscape architects and designers aim to minimize the reliance on treated drinking water for irrigation, which helps preserve valuable water supplies.

This reduction in potable water usage is crucial in addressing environmental concerns, as it not only supports conservation efforts but also aligns with broader goals of sustainability and responsible resource management. Efficient irrigation systems typically feature technologies such as drip irrigation, smart controllers, and drought-resistant plant selections that collectively contribute to significant water savings.

The focus on reducing potable water use also supports regional regulations and sustainability initiatives, encouraging practices that are environmentally friendly and economically viable. Thus, this option stands out as the primary goal of CALGreen's framework for landscape irrigation.
