What is the minimum distance for overhead irrigation from non-permeable surfaces?

The minimum distance for overhead irrigation from non-permeable surfaces is 24 inches. This distance is important for several reasons.

First, a separation of 24 inches helps to ensure that water does not directly runoff onto non-permeable surfaces, such as concrete or asphalt. These surfaces do not absorb water, leading to potential issues such as water pooling, erosion, or increased runoff. The goal is to allow proper infiltration into the surrounding soil areas and minimize waste.

Additionally, this distance can help prevent issues related to water quality. Excessive runoff from non-permeable surfaces can carry pollutants into stormwater systems and water bodies, risking contamination. Maintaining this minimum distance serves to mitigate these environmental concerns.

Overall, adhering to the 24-inch requirement is critiqued to promote sustainable irrigation practices.
