AWWA Water Efficiency Exam 2026 | Latest
Questions And Answers
Authorized consumption - correct-answer -the annual volume of metered and/or
unmetered water taken by registered customers, the water supplier and others
who are authorized to do so.
Baseline - correct-answer -an established value or trend used for comparison
when conditions are altered
Benefit cost ration - correct-answer -benefits and costs measured in terms of
money and expressed as a ratio with divided by costs; typically used as an
evaluation tool for different water conservation measures and programs.
Best management practice (BMP) - correct-answer -a set of practices, measures,
or procedures that are beneficial, empirically proven, cost-effective, and widely
accepted by the professional community.

Block rate pricing - correct-answer -a method of charging for water based on the
volume used. As more water is used, the price increases (or decreases) through a
series of blocks. These pricing structures are designed to encourage efficient use
of a resource.
Catch-can test - correct-answer -a measurement of precipitation from a sprinkler
system in which water is collected in graduated containers (catch cans) placed at
evenly spaced intervals for a specific period of times.
Central Irrigation control - correct-answer -a computerized system that programs
sprinkler clocks from a centralized location using a computer.
Closed-loop cooling tower - correct-answer -water conserving cooling tower
system in which water used for cooling is recycled through a piping system that
cools the water' the water is cooled as air exchanges heat with the pipes.
Codes and standards - correct-answer -a set of requirements governing the design
and performance of water using fixtures or devices, adopted by a nationally or
internationally recognized code setting standard setting organizations.

Conservation pricing - correct-answer -water rate structures that increase the
price of water as more water is used with the goal of encouraging more efficient
use.
Consumptive use (evapotranspiration) - correct-answer -combined amounts of
water needed for transpiration by vegetation and for evaporation from adjacent
soil, snow, or intercepted precipitation. Also called crop requirement, crop
irrigation requirement, and consumptive use requirement.
Continuous flow system - correct-answer -the continuous use, by an industry, of
deionized water to remove contaminants from products and equipment.
Cooling tower makeup - correct-answer -water added to the recirculating cooling
tower water stream to compensate for water evaporation losses.
Cooling water - correct-answer -water typically used to cool heat-generating
equipment or to condense gases in a thermodynamic cycle.
Cooling water blowdown - correct-answer -procedure used to reduce total
dissolved solids by removing a portion of low quality recirculating water
