The "I" section on a mound sheet indicates which characteristic?

Explanation:
On a mound sheet, symbols show how the grade runs so wastewater can flow by gravity. The I section marks the side where the ground slopes downward—the downhill direction. This orientation is essential because effluent should move toward the outlet; a downhill slope ensures drainage and prevents pooling. If the section were uphill or flat, gravity wouldn’t drive the flow properly, and an inverted orientation would reverse how the slope works. So the I section indicates a downhill slope.
