Ga. Comp. R. & Regs. R. 391-3-33-.02 - Definitions
When used in this Chapter:
(1) "Apparent losses" means the sum of
unauthorized consumption (theft or illegal use), customer water meter
under-registration (inaccuracies with customer water meters) and data handling
errors (meter reading and billing).
(2) "Billed metered consumption" means all
metered consumption which is billed from all groups of customers, such as
domestic, commercial, industrial or institutional. It does not include water
that is metered and then billed, and exported to neighboring public water
systems.
(3) "Certification
statement" means that a Qualified Water Loss Auditor has certified that the
auditor has examined the annual water loss audit results and the results meet
the requirements in the Georgia Water System Audits and Water Loss Control
Manual and the American Water Works Association methodology for water loss
auditing.
(4) "Current Annual Real
Losses (CARL)" means the real losses determined during the reporting
year.
(5) "Director" means the
Director of Environmental Protection Division of the Department of Natural
Resources.
(6) "Division" means the
Environmental Protection Division of the Department of Natural
Resources.
(7) "Economic Level of
Leakage" means the determination of the level of real (leakage) losses where
the sum of the cost of the real loss reduction and the cost impact of the real
losses is at a minimum. Reducing leakage levels below the Economic Level of
Leakage is not cost-effective, as the cost of the leak abatement activities
exceeds the value of water saved. Economic Level of Leakage is used for leakage
reduction target setting and setting the frequency of leak survey
investigations.
(8)
"Infrastructure Leakage Index (ILI)" means the dimensionless performance
indicator calculated by dividing the Current Annual Real Loss by the
Unavoidable Annual Real Loss (i.e., CARL / UARL) best used for benchmarking
leakage within a public water system.
(9) "Non-Revenue Water" means the sum of
apparent losses, real losses, and authorized water consumption (unbilled
metered and unmetered) that does not provide any revenue to the
utility.
(10) "Operational Basic
Apparent Losses" means a basic performance indicator that assesses Apparent
Losses in gallons per service connection per day.
(11) "Operational Basic Real Losses" means a
basic performance indicator that assesses Real Losses in gallons per service
connection per day or gallons per miles of water distribution mains per day
depending on the public water system's connection density.
(12) "Public water system" means a system for
the provision to the public of piped water for human consumption, if such
system regularly serves at least 3,300 individuals. Such term includes but is
not limited to any collection, treatment, storage, and distribution facilities
under the control of the operator of such system and used primarily in
connection with such system and any collection or pretreatment storage
facilities not under such control which are used primarily in connection with
such system.
(13) "Qualified Water
Loss Auditor" means an individual who has completed a basic water loss auditing
course approved by the Division and who demonstrates the knowledge, skills and
ability to validate water loss audits in accordance with the Georgia Water
System Audits and Water Loss Control Manual.
(14) "Real Losses" means the physical water
losses from reservoir(s), the water treatment facility(ies), the pressurized
public water system and the finished water storage tanks, up to the point of
customer consumption. In metered systems this is the customer meter; in
unmetered situations this is the first point of consumption within the
property. The annual volume lost through all types of leaks, breaks and
overflows depends on frequencies, flow rates, and average duration of
individual leaks, breaks and overflows.
(15) "Unavoidable Annual Real Losses (UARL)"
means a theoretical reference value representing the technical low limit of
leakage that could be achieved if all of current best technology could be
successfully applied and is a key variable in the calculation of the
Infrastructure Leakage Index.
(16)
"Unbilled metered consumption" means metered water consumption which is, for
any reason, unbilled and does not include water exported to neighboring public
water systems or utilities that is metered but unbilled.
(17) "Unbilled unmetered water consumption"
means any kind of water consumption authorized by the public water system which
is neither billed nor metered, and may include items such as fire-fighting,
flushing of mains and sewers, or street cleaning, and does not include water
exported to neighboring public water systems or utilities that is unmetered and
unbilled.
(18) "Water audit data
validity score" means a weighted scale, from 0 to 100, for the components of
consumption and water loss that demonstrates a public water system's confidence
and accuracy of data entered into a water audit software application.
(19) "Water loss audit" means the
investigation and completion of an assessment of public water system
infrastructure leakages and other losses in conformance with the Georgia Water
Loss Audit guidance, International Water Association (IWA) and American Water
Works Association (AWWA) methodology for water loss auditing and the latest
release of the AWWA Water Loss Audit software application package.
(20) "Water exported" means the water sold to
a neighboring water utility, public water system or regional water
authority.
(21) "Water use
efficiency" means the minimal amount of water that is technically and
economically feasible to achieve an intended water use function and reduce
water waste.
