Question 1

Which AWWA-endorsed methodology provides a standardized framework for utilities to perform water loss audits and calculate their infrastructure leakage index (ILI)?

Accepted Answer

AWWA M36 Free Water Audit Software methodology

Answer

The AWWA M36 water audit methodology and accompanying free software provide utilities a standardized, validated approach to quantify water losses and calculate the ILI benchmark.

Question 2

A utility implements aquifer storage and recovery (ASR) to store treated water underground during wet periods for use during droughts. What is the primary sustainability benefit?

Accepted Answer

Balances seasonal supply and demand while reducing reliance on surface water during low-flow periods

Answer

ASR stores surplus treated water in aquifers during high-supply periods and recovers it during peak demand or drought, effectively banking water and reducing surface water withdrawals when flows are critically low.

Question 3

Utilities track sustainability performance using benchmarking. Which organization provides the primary benchmarking and performance indicator framework used by U.S. water and wastewater utilities?

Accepted Answer

American Water Works Association (AWWA)

Answer

AWWA's Utility Benchmarking program and its QualServe initiative provide standardized performance indicators that allow utilities to compare operational, financial, and environmental metrics against peers.

Question 4

Climate change adaptation planning for a water utility most critically requires addressing which operational risk?

Accepted Answer

Shifts in precipitation patterns affecting source water availability and quality

Answer

Climate change alters precipitation, temperature, and hydrology, directly threatening source water quantity and quality—making supply reliability and treatment adaptability the primary operational risks to address.

Question 5

Active leak detection programs using acoustic correlators and district metered areas (DMAs) primarily help utilities accomplish which goal?

Accepted Answer

Locate and repair hidden distribution system leaks to reduce real water losses

Answer

Acoustic correlators and DMAs enable proactive identification of hidden pipe leaks in the distribution system before they surface, directly reducing real (physical) water losses.
