AWWA Water Efficiency practice
exams with correct answers
2026/2027
Adaptive plants - ANSWER-Non-indigenous plants that easily adapt to the
climate and thus require little or no supplemental irrigation once established.
Adjusted water budget - ANSWER-an amount of water used to maintain a
landscape that is based on area and evapotranspiration rate.
American National Standards Institute (ANSI) - ANSWER-an association
involved in developing standards for a wide range of products including
plumbing fixtures.
American Society of Mechanical Engineers (ASME) - ANSWER-a professional
organization whose Codes and Standards Committee helps to write and
publish ANSI standards
American Water Works Association (AWWA) - ANSWER-a professional
organization serving the drinking water supply profession in North America.
American Water Works Association Research Foundation (AWWARF) -
ANSWER-a nonprofit organization that sponsors research for the drinking
water supply profession.
Apparent loss - ANSWER-water that was not read accurately by a meter,
either as unauthorized consumption, including theft or data analysis errors.
,Appliance - ANSWER-a water using device such as a washing machine.
Audit (end use) - ANSWER-a systematic accounting of water uses conducted
to identify opportunities for improved efficiency.
Authorized consumption - 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 - ANSWER-an established value or trend used for comparison when
conditions are altered
Benefit cost ration - 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) - 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 - 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 - 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 - ANSWER-a computerized system that programs
sprinkler clocks from a centralized location using a computer.
, Closed-loop cooling tower - 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 - 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 - 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) - 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 - ANSWER-the continuous use, by an industry, of
deionized water to remove contaminants from products and equipment.
Cooling tower makeup - ANSWER-water added to the recirculating cooling
tower water stream to compensate for water evaporation losses.
Cooling water - ANSWER-water typically used to cool heat-generating
equipment or to condense gases in a thermodynamic cycle.
Cooling water blowdown - ANSWER-procedure used to reduce total dissolved
solids by removing a portion of low quality recirculating water
