Conservation Plan Guidelines
Water is second only to air in that we can live without air
for several minutes Ð without water for several days. Water conservationÕs time
has come, in our communities, our state, our nation and our planet.
G. Tracy Mehan, III, former
Assistant Administrator for Water with the U.S. Environmental Protection Agency
states, ÒIf we are to sustain the water infrastructure that is so important to
the health of people and the environment, we must be smarter about water
use. We must manage demand, reclaim
and reuse municipal wastewater, recycle industrial process water, and begin to
think in a more integrated fashion about water management.Ó

BACKGROUND
The State of
In October 2003, the first draft of a statewide water
conservation plan was proposed. A
public comment period followed and concluded on
The Statewide Water Conservation Program will only be
successful if
á
Growing
statewide population, one of the fastest in the nation, is increasing water
demands.
á
StateÕs water
supplies are fixed; alternative water supplies such as reclaimed and
desalinated water are costly and would impose severe rate increases on
consumers that could be minimized or avoided by first reducing unnecessary
water waste.
á
Excessive and
wasteful water use increases consumer and state capital and operation and
maintenance costs to build and maintain infrastructure for water, wastewater,
reclamation, and other supply facilities.
á
Increasing
statewide water use, especially for nonessential demands such as excessive lawn
watering and other forms of irrigation, contribute to stream flow diminishment
and associated impacts on fisheries, recreation and tourism, threatening both
the stateÕs environment and long-term economy.
á
There exist
numerous state laws, rules and policies that require or promote water
conservation. For example,
It
has been estimated that most
To facilitate the
monitoring of statewide water use and efficiency improvements, DNRÕs existing administrative annual ground water and
surface water permit reporting program shall be enhanced to maintain a
statewide database of water used by each major use sector (system/utility UFW,
residential, multi-family, industrial, commercial, and institutional/public,
irrigation, agricultural, and other). Local and regional water use statistics
shall be reported annually to the state for publication in the stateÕs annual
water use report. Data to be reported annually shall include:
1.
Volume of
total available water supplies
2.
Total volume
of water produced, monthly and annually
3.
Total volume
of metered water use, by customer category or other described end-user, monthly
and annually
4.
Description of
volumetric water savings and changes from prior year, with discussion of
conservation goals and plans.
5.
Description of
customer water rate structure (conservation-oriented or not
conservation-oriented) and related charges
6.

To help
realize water conservation goals, EPD shall establish water efficiency
benchmarks for each major category of water user. Benchmarks help water users measure
their relative water use efficiency and to judge whether improvements could be
made to save water. Water
efficiency benchmarks are a direct, simple and practical measurement tool for
the public, private sector, government, and the media to understand what is
efficient water use and what is wasteful water use. Performance benchmarks
abound in our culture, science and medicine; water managers need them, too. Not
unlike the BMIÐbody mass indexÐbenchmark for human body weight, some water
users will fall below and others will meet or exceed their water efficiency
threshold.
Water
users who exceed their water efficiency standards can reduce their use through
the implementation of efficiency measures and thus are good candidates for
participation in water conservation programs. Such information can help in the
evaluation of groundwater and surface water permit renewals and applications. For example, how Community A compares to
Community B in terms of average (year-round) single family water use will
demonstrate each townÕs relative water use efficiency. In some cases, an
application for a new water supply permit may be contingent on the adoption of
water efficiency measures that will lower average use to meet established
benchmarks.
Benchmarks for water use efficiency shall be established for
all major categories of water end-users in

Agricultural
water efficiency benchmarks
á
To be
established within two (2) years (see ÒMonitoring of Water UseÓ section below)
Explanation:
Agricultural water use efficiency benchmarks can be based on several criteria,
including: total volume of water used, units of crops produced per unit of
water, irrigated area, and irrigation type.
The development of
agricultural water efficiency benchmarks can be enhanced by the establishment
of Georgia-based agricultural water efficiency best management practices. One
example of agricultural BMPs is the State of
California Department of Water Resources voluntary Efficient Water Management
Practices (EWMPs) for agricultural water suppliers,
as shown below. The EWMPs consist of three lists:
List A measures are generally considered to be applicable to all agricultural
water districts and suppliers; List B measures are applicable when subject to a
net present analysis; and List C measures are applicable when subject to a
detailed net present analysis.
|
|
List A:
Generally Applicable Practices |
1. Prepare and
adopt a water management plan using the MOU as a guideline. |
2. Designate a
Water Conservation Coordinator. |
3. Support the
availability of water management services to water users. |
4. Improve
communication and cooperation among water suppliers, water users, and other
agencies. |
5. Evaluate the
need for changes in policies. |
6. Evaluate and
improve efficiencies of water suppliersÕ pumps. |
List B:
Conditionally Applicable Practices |
1.Facilitate alternative land use. |
2. Facilitate use
of available recycled urban wastewater. |
3. Facilitate the
financing of capital improvements for on-farm irrigation systems. |
4. Facilitate
voluntary water transfers. |
5. Line or pipe
ditches and canals |
6. Increase
flexibility in water ordering |
7. Construct and
operate water supplier spill and tailwater recovery
systems |
8. Optimize
conjunctive use of surface water and groundwater |
9. Automate canal
structures |
List C:
Other Practices |
1. Water
Measurement and Water Use Report |
2. Pricing or Other
Incentives |

MANDATORY
WATER CONSERVATION INCENTIVES AND MEASURES
Achieving water savings through conservation involves a
combination of incentives and measures. Incentives are essential to motivating
water users to adopt a water efficiency measure Ð technology and/or practice
that reduces water use.
Conservation incentives
Conservation incentives consist of a range of voluntary and
mandatory educational, regulatory, and financial Òcarrots and sticks that inspire,
require, and/or speak to the financial bottom line of water suppliers and
customers.
No later than __________________(suggested date: December
31, 2005), existing and future ground and surface water permit holders must
have the following conservation incentives in effect or else they will not be
granted renewals, increases and modifications:
á
Conservation-oriented
rate structures. Suppliers shall
also establish revenue stabilization accounts to ensure adequate revenues from
water demand reductions from conservation.
á
Local water
waste prohibition that includes increasing fines for violators
á
Annual
distribution of annual water use and conservation information booklet
á
Mandatory
irrigation schedule, allowing for a maximum of 3 irrigation cycles per week,
not to exceed 30 minutes per irrigated area (30-day exemptions allowed for sod
and new turf plantings). Reduced irrigation schedules, such as a maximum of one
(1) or two (2) times per week and for no longer than 30 minutes each day, are
encouraged to minimize water waste and lower excessive summer peak demands.
Conservation Measures
Conservation
measures include water efficient ÒhardwareÓ devices, technologies, and
equipment and practices that reduce water use. There are over 100 water
efficiency technologies and practices that can be applied to water systems,
homes, industries, businesses, public facilities, and farms.
No
later than __________________(suggested date: December 31, 2006), existing and
future ground and surface water permit holders must provide at least the
following conservation assistance programs to their customers or else they will
not be granted renewals, increases and modifications:
á
Water and
non-potable water providers and utilities: Compliance with state 10% UFW goal
or approved UFW reduction plan.
á
Residential:
home water audit and leak detection every two (2) years, high-efficiency
plumbing and appliance retrofit and rebate programs, Irrigation schedule:
allowing for a maximum of 2-3 irrigation cycles per week, not to exceed 30
minutes per irrigated area (30-day exemptions allowed for sod and new turf
plantings).
á
Industrial,
Commercial, and Institutional/Public: meter sizing and accuracy inspection at
least every two (2) years, water audit and leak detection every two (2) years,
cooling tower and high water use audit every two (2) years, Irrigation
schedule: allowing for a maximum of 2-3 irrigation cycles per week, not to
exceed 30 minutes per irrigated area (30-day exemptions allowed for sod and new
turf plantings).
á
Irrigation for
golf courses and playing fields: field audit of irrigation systems and water
use efficiency, irrigation water efficiency budget, including meter sizing and
accuracy, every two (2) years.
á
Agricultural:
onsite evaluation of water volumes used for irrigation and livestock every two
(2) years, estimation of water use efficiency of irrigation equipment and
methods, irrigation water efficiency budget, and recommendations for efficiency
improvements every two (2) years.
LOCAL AND STATE SUPPORT
Support for the
stateÕs water conservation requirements in the form of financial, policy, and
public education assistance will be needed from local as well as state
authorities. A mix of technical, legal, financial and programmatic strategies
will be utilized and include, but not be limited to, the following elements:
á
Water
suppliers are encouraged to establish water efficiency incentives, including
conservation-oriented water rate structures such as inclining rate blocks and
seasonal (summer) use surcharges that discourage unnecessary usages (e.g.,
excessive lawn watering and neglected leaks).
á
Planning and
implementation of water conservation plans, including but not limited to
program components required by existing water supply permit(s). Conservation
programs shall include an appropriate combination of conservation incentives
and measures, with an emphasis on the achievement of measurable and permanent,
long-term savings.
á
Local
authorities will use a portion of revenue generated from water conservation
rate structures to fund water conservation staffing, programming and education
in their communities.
The
DNR and other state agencies shall support state and local water conservation
goals and objectives through a variety of policies, programs, and direct
assistance. These efforts shall include but not be limited to:
á
Educational
outreach to the public and private sector concerning the stateÕs water supply
condition and related conservation needs shall be ongoing through the creation
and dissemination of information in print materials, the Internet, public
service announcements, and related.
DNRÕs Office of Water Conservation will take
the lead on this and other state agencies will provide support for such efforts
as appropriate to each agencyÕs mission and scope.
á
Technical
assistance for conservation program planning, implementation, and monitoring,
including guidance on the establishment of conservation-oriented pricing
structures shall be coordinated and provided through the DNRÕs
Office of Water Conservation. Water use audits for farms, businesses, and local
governments shall be administered by the DNRÕs
Pollution Prevention Assistance Division.
á
Financial
support in the form of state grants and low-interest loans for local and
regional conservation programs to conduct water conservation incentive programs
shall be administered by the Georgia Environmental Facilities AuthorityÕs loan
program.
á
DNRÕs Office of Water Conservation, in cooperation with the
Pollution Prevention Assistance Division, shall develop a plan and lead the
implementation of water audits in statewide buildings and facilities.
á
The state
shall establish a five-year Georgia Water Conservation Trust Fund (WCTF), to be
administered by the State Water Conservation Program, to commence in 2005 and
sunset in 2010, that will finance statewide conservation efforts to support
local, regional and state conservation programs designed to meet the goals
described herein. Potential sources
of funding include:
á
Revenues from
local and regional water suppliers who shall levy an annual water conservation
program incentive fee on active customer accounts based on meter size. For example, single- family residential
accounts (5/8-inch and 3/4-inch meters) shall be assessed $10 annually for five
years; commercial accounts (3/4-inch and 1-inch meters) shall be assessed $25
annually for five years. Notice of
this annual assessment fee shall be imbedded in a report sent to all water
customers that includes a description of the stateÕs water supply status,
goals, descriptions of conservation measures to save water, and information
about how water users can access the programs and services for saving water
that are provided by the Georgia WCTF.
á
Revenues for
this fund may be collected by establishing water use permit fees for new and
renewed drinking water, ground water and surface water permits. A portion of the funds collected will be
returned to the local communities in the form of technical assistance grants.
á
The DNR
Program Support Division (PSD) will take a leadership role in water
conservation by working with the DNR Water Conservation Program to implement a
water conservation program that will work towards the implementation of water
use efficiency measures in state facilities and infrastructure. One model for such an effort is the
federal government. The
