What is the purpose of designing a well to the anticipated yield?

• A. To prevent flooding in the surrounding area
• B. To ensure the well can meet water demand without over-extraction
• C. To guarantee the well remains functional indefinitely
• D. To minimize water evaporation from the well

Answer: (B)

Designing a well to the anticipated yield is crucial for ensuring that the well can meet water demand without over-extraction. By calculating and considering the sustainable yield—meaning the amount of water that can be withdrawn from the aquifer without depleting it—engineers and water resource managers can create a system that balances usage with natural replenishment rates. This approach helps maintain the integrity of the aquifer and ensures a reliable water supply for both current and future needs. If a well is over-designed to extract more water than the aquifer can naturally replenish, it can lead to significant environmental issues, such as depletion of the water source, lowered water tables, and potential negative impacts on surrounding ecosystems. Thus, aligning the well's design with the anticipated yield protects the resource while fulfilling demand.
