AWWA Water Efficiency Questions And Answers
Verified 100% Correct
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
Cool-season grass - ANSWER -turf grass varieties that are typically not damaged
by subfreezing temperatures. Includes bluegrass, Kentucky bluegrass, perennial rye
grass, red fescue, and tall fescue.
Decreasing block rate - ANSWER -pricing that reflects per-unit costs of
production and delivery that go down as customers consume more water.
Demand management - ANSWER -the practice of systematically reducing water
use for a broad spectrum of utility customers through efficiency measures and
conservation, often as an alternative to purchasing new water or expanding water
treatment facilities.
