Authorized con- the annual volume of metered and/or unmetered water taken by registered
sumption customers, the water supplier and others who are authorized to do so.
11. Baseline an established value or trend used for comparison when conditions are altered
12. Benefit cost ra- benefits and costs measured in terms of money and expressed as a ratio with di-
tion vided by costs; typically used as an evaluation tool for different water conservation
measures and programs.
13. Best manage- a set of practices, measures, or procedures that are beneficial, empirically proven,
ment practice cost-effective, and widely accepted by the professional community.
(BMP)
14. 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.
15. 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.
16. Central Irrigation a computerized system that programs sprinkler clocks from a centralized location
control using a computer.
17. Closed-loop cool- water conserving cooling tower system in which water used for cooling is recycled
ing tower through a piping system that cools the water' the water is cooled as air exchanges
heat with the pipes.
18. Codes and stan- a set of requirements governing the design and performance of water using
dards fixtures or devices, adopted by a nationally or internationally recognized code
setting standard setting organizations.

Conservation water rate structures that increase the price of water as more water is used with
pricing the goal of encouraging more efficient use.
20. Consumptive combined amounts of water needed for transpiration by vegetation and for
use evaporation from adjacent soil, snow, or intercepted precipitation. Also called crop
(evapotranspira- requirement, crop irrigation requirement, and consumptive use requirement.
tion)
21. Continuous flow the continuous use, by an industry, of deionized water to remove contaminants
system from products and equipment.
22. Cooling tower water added to the recirculating cooling tower water stream to compensate for
makeup water evaporation losses.
23. Cooling water water typically used to cool heat-generating equipment or to condense gases in
a thermodynamic cycle.
24. Cooling water procedure used to reduce total dissolved solids by removing a portion of low
blowdown quality recirculating water
25. Cool-season turf grass varieties that are typically not damaged by subfreezing temperatures.
grass Includes bluegrass, Kentucky bluegrass, perennial rye grass, red fescue, and tall
fescue.
26. Decreasing block pricing that reflects per-unit costs of production and delivery that go down as
rate customers consume more water.
27. Demand man- the practice of systematically reducing water use for a broad spectrum of utility
agement customers through efficiency measures and conservation, often as an alternative
to purchasing new water or expanding water treatment facilities.
