Which statement best describes the purpose of storage/impoundment in irrigation systems?

• A. To store water for peak demand and maintain pressure during outages.
• B. To provide decorative water features.
• C. To reduce the need for proper zoning.
• D. To cure water hardness.

Answer: (A)

Storage or impoundment acts as a water reserve that smooths supply variations and keeps system pressure stable during peak demand and outages. With a reservoir available, the irrigation system can draw water during times of high use or when the source is interrupted, reducing pump cycling and maintaining more uniform pressure across zones. This helps ensure consistent irrigation performance and protects equipment from short-cycling and pressure drops. It’s not intended for decorative water features, it doesn’t replace proper zoning for distributing water efficiently, and it doesn’t affect water hardness.
