AWWA Water Efficiency Exam with precise detailed solutions
|| || || || || || ||
Adaptive plants - ✔✔Non-indigenous plants that easily adapt to the climate and thus
|| || || || || || || || || || || || ||
require little or no supplemental irrigation once established.
|| || || || || || ||

|| || || || || || || || || || || || || || ||
on area and evapotranspiration rate.
|| || || || ||
American National Standards Institute (ANSI) - ✔✔an association involved in developing
|| || || || || || || || || || ||
standards for a wide range of products including plumbing fixtures.
|| || || || || || || || ||

|| || || || || || || || || || ||
Codes and Standards Committee helps to write and publish ANSI standards
|| || || || || || || || || ||
American Water Works Association (AWWA) - ✔✔a professional organization serving the
|| || || || || || || || || || ||
drinking water supply profession in North America.
|| || || || || ||
American Water Works Association Research Foundation (AWWARF) - ✔✔a nonprofit
|| || || || || || || || || ||
organization that sponsors research for the drinking water supply profession.
|| || || || || || || || ||
Apparent loss - ✔✔water that was not read accurately by a meter, either as unauthorized
|| || || || || || || || || || || || || || ||
consumption, including theft or data analysis errors. || || || || || ||
Appliance - ✔✔a water using device such as a washing machine.
|| || || || || || || || || ||
Audit (end use) - ✔✔a systematic accounting of water uses conducted to identify
|| || || || || || || || || || || || ||
opportunities for improved efficiency. || || ||
,2
Authorized consumption - ✔✔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 - ✔✔an established value or trend used for comparison when conditions are
|| || || || || || || || || || || || ||
altered
Benefit cost ration - ✔✔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) - ✔✔a set of practices, measures, or procedures that are
|| || || || || || || || || || || || || ||
beneficial, empirically proven, cost-effective, and widely accepted by the professional
|| || || || || || || || || ||
community.
Block rate pricing - ✔✔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 - ✔✔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 - ✔✔a computerized system that programs sprinkler clocks from a
|| || || || || || || || || || || || ||
centralized location using a computer. || || || ||
Closed-loop cooling tower - ✔✔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.
|| || || || ||
, 2
Codes and standards - ✔✔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 - ✔✔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) - ✔✔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 - ✔✔the continuous use, by an industry, of deionized water to
|| || || || || || || || || || || || || ||
remove contaminants from products and equipment.
|| || || || ||
Cooling tower makeup - ✔✔water added to the recirculating cooling tower water stream to
|| || || || || || || || || || || || || ||
compensate for water evaporation losses. || || || ||
Cooling water - ✔✔water typically used to cool heat-generating equipment or to condense
|| || || || || || || || || || || || ||
gases in a thermodynamic cycle.
|| || || ||
Cooling water blowdown - ✔✔procedure used to reduce total dissolved solids by removing
|| || || || || || || || || || || || ||
a portion of low quality recirculating water
|| || || || || ||
Cool-season grass - ✔✔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 - ✔✔pricing that reflects per-unit costs of production and delivery
|| || || || || || || || || || || || ||
that go down as customers consume more water.
