For non-residential projects over 1,000 square feet, what is one requirement?

Irrigation sub-meter installation is essential for non-residential projects exceeding 1,000 square feet because it allows for the accurate measurement of water usage specifically for irrigation purposes. This approach helps to conserve water and promote sustainable practices by enabling property owners and managers to monitor their irrigation efficiency closely. By having a dedicated sub-meter, it becomes easier to track how much water is being used for landscaping, which is crucial in areas facing water scarcity and regulatory scrutiny regarding water use.

This also facilitates compliance with local ordinances aimed at promoting water conservation, as it provides a tangible means to evaluate and adjust irrigation practices based on actual consumption data. Overall, sub-meters play a crucial role in effective water management strategies within landscape architecture, particularly for larger, non-residential projects.
