I. Introduction Water conservation, or the beneficial reduction of water use, waste, and loss, is a critical management tool to meet future water demand needs in Georgia. Water conservation can help Georgia ensure enough clean water for future generations, for sustainable economic development, and for maintaining healthy aquatic systems. Georgia is rich in freshwater capital. However, our water demand is increasingly becoming a critical issue as our population grows, as demand increases, as two areas of the state are under water withdrawal moratoria, and as our aquatic systems are becoming more stressed. Our ever-increasing need for clean water today threatens our ability to have enough water for future generations and to maintain the health of our rivers, lakes, streams, and aquifers. This paper addresses the need for a strategic water conservation program in Georgia and suggests mechanisms and measures to reduce water supply demand. II. Background We have been living under supply-driven water management in Georgia. In other words, we allow water users’ consumption to drive the State to rely on technological solutions for new sources of water, rather than managing our demand for water. Demand management is the best way to extend our water supply, and it is crucial because water supplies are fixed. Technological solutions, such as reservoirs, come at a high cost to the aquatic environment and to local government coffers. Reservoirs alter natural water flow and change the timing, amount, and duration of flows, upon which native fish species and Georgia wildlife depend (Cowie 2002). Often overlooked are the social impacts on downstream communities. Reservoirs affect their drinking water supplies, their ability to grow and meet their municipal wastewater permit limits, their ability to attract new industries or for their existing industries to meet wastewater discharge limits, and the reduced flows from upstream reservoirs can negatively impact recreation, tourism, and commercial fishing—all of which translate into millions of dollars for Georgia’s economy. Although reservoirs store water for when it is needed, they do not create or conserve water. Instead, they result in a net loss of water due to more surface water evaporation (Cowie 2002). Water conservation, efficiency, and reuse together will reduce excessive demand and allow us to look beyond engineered ways to increase the availability of a finite resource. Considering that the average Georgian consumes 10% more than the average water user nationally, reducing our demand for water is an obvious first step in finding “new” supplies of water (Fanning 2000). Managing demand is typically best done on a regional basis and is geared to the largest type of water use. For instance, residential water use, which is the largest water use in the 16-county, Metropolitan North Georgia Water Planning District (the “Metro District”), is the focus of conservation efforts in the Atlanta area. Likewise, agricultural irrigation would be the focus of conservation efforts in southwest Georgia, and municipal and industrial use would be the primary focus in coastal Georgia. The Metro District predicts that its 16-county area will not be able to meet its water supply demands by 2030 if there is no change in our current levels of water consumption. The Metro District has set a goal of 11% reduction in water demand through water conservation, and has implemented several conservation mechanisms, but other metropolitan areas like Seattle and Albuquerque have reduced their per capita demand since the 1990’s by 20% and 30% respectively. Conservation plans in Atlanta could and should be much more aggressive. Below the Fall Line, both southwest and coastal Georgia are feeling the impact of over pumping groundwater. In some river basins in southwest Georgia, agricultural irrigation comprises as much as 90% of the water used during the April-September growing season (McDowell 2005). In 1999, the Environmental Protection Division (EPD) placed a moratorium on new agricultural groundwater withdrawals from the Floridan aquifer in the lower Flint River basin in response to a combination of a prolonged drought, dramatically increased agricultural irrigation since the late 1970’s, and scientific studies that predicted severe impacts on stream flows due to excessive groundwater withdrawals from the Floridan aquifer. In the Coastal Plain region, industry and mining are the largest groundwater consumers, using 53% of the groundwater withdrawn. The second largest sector is public supply, which consumes 23%, and irrigation accounts for 13%. Thermoelectric (fossil fuel and nuclear facilities) power production accounts for 83% of surface water use (Fanning 1999). In 1997, EPD adopted the interim strategy for the 24-county Coastal Plain due to continued lowering of the groundwater table and saltwater intrusion. In addition to research, the interim strategy called for restrictions on new groundwater withdrawals from the Floridan aquifer in Glynn, Chatham, lower Bryan, and lower Effingham counties and additional limits on the surrounding area. In 2002, EPD was obliged to place absolute restrictions on new water withdrawals from the Upper Floridan aquifer. This cap was triggered by EPD’s analysis that they had gone beyond the withdrawal limitations by an estimated 30% due to the upwelling of demand by the agricultural and industrial sectors. III. Regulations, Rules and Policies Relating to Water Conservation In the most general sense, Georgia’s regulated riparian law promotes water conservation, because it requires that all potential users be guaranteed the right of reasonable use. Therefore, water resources cannot be so over-allocated that potential legitimate downstream water users do not have sufficient water for their needs. Users are not entitled to waste water, because wasteful use is not “reasonable.” Two specific Georgia laws influence water conservation: the Georgia Water Quality Control Act (O.C.G.A §§ 12-5-20 et seq.) and the Ground-water Use Act (O.C.G.A. §§ 12-5-90 et seq.). Under both statutes, permits are required for withdrawals of surface or groundwater, respectively, in excess of 100,000 gallons per day. Both statutes also require the applicant to prepare water conservation plans for all non-farm use permits. The Rules for Groundwater Use (Ga. Comp. R. & Regs, § 391-3-2) and Water Quality Control (Ga. Comp. R. & Regs, § 391-3-6) include guidelines for submitting specific components under the water conservation plans including details regarding system management (e.g. 12-months of data on unaccounted for water), treatment management (e.g. water metering details), rate making policies, plumbing ordinances and codes, recycling or reuse, and education programs (Keyes 2005a). In the last ten years, Georgia has taken a few steps toward improving its water conservation policy. In 1994, the Board of Natural Resources adopted federally mandated municipalities to adopt efficient energy standards, which included low-flow plumbing standards for new construction (Keyes 2005b). In 2001, the Georgia General Assembly passed the Metropolitan North Georgia Water Planning Act, which created a planning entity to comprehensively manage water supply and quality in the 16-county metropolitan region. The Act called for both water supply and water conservation plans and required the EPD Director to ensure compliance (or good faith efforts by local governments) with the Metro District plans prior to approving any new or expanded water supply withdrawal or wastewater discharge permit application. In 2003, the DNR Board adopted the statewide Drought Management Plan, which included outdoor watering schedules based on both drought and non-drought conditions, and in 2004, the Board passed permanent outdoor watering restrictions that apply year-round. Also in 2003, the Georgia General Assembly passed HB 579, which called for the metering of agricultural water use, which is a first step in being able to measure the effects of water conservation in the agricultural sector. Finally, EPD proposed a Statewide Water Conservation Plan in 2004, but it was never adopted. In addition to these initiatives, two federal laws contain provisions that encourage water conservation under specific conditions: the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.) and the Endangered Species Act (ESA)(16 U.S.C. §§ 1531 et seq.). In order for municipalities and businesses to comply with their obligations under the CWA, a certain level of instream flow is needed to assimilate waste (from both point source and non-point source pollution) and to maintain water quality. Under the CWA, a certain level of instream flow is needed to assimilate waste (from both point source and non-point source pollution) and to attain water quality standards. Under the ESA, governments could face severe penalties if permitted withdrawals do not leave sufficient water levels to support the viability of an endangered species. In 1999, sufficient surface water levels required to support four species of federally protected fresh water mussels became an issue in the Flint River Basin due to the extended drought of 1999-2002 and increased agricultural irrigation since the 1970’s. IV. Key Components of a Statewide Water Conservation Plan Because water conservation is the state’s first and least expensive means of providing adequate water supply, the state should aggressively implement effective water conservation mechanisms and measures across all sectors including residential, industry, agriculture, landscapes, government, and water utilities. As an initial matter, a statewide water conservation plan should be based on river basins, not political boundaries, and should consider both aquifers and surface waters in an integrated way. At a minimum, the following eight components are needed for a successful statewide program (adapted from Keyes et. al. 2004).
Statewide benchmarks for water conservation and reuse measures must be established through the statewide planning process. At a minimum, the following benchmarks should be adopted statewide:
V. Strategic Mechanisms for Water Conservation and Reuse in Georgia “Mechanisms” are either mandates or incentives to reduce demand that are implemented through regulation, education, or funding. A. Regulation. Examples of regulatory mechanisms include water-efficiency policies and ordinances, laws and plumbing codes for water-efficient fixtures and appliances, standards for landscape design, irrigation scheduling, penalties for outdoor water waste, pollution prevention requirements, and water demand offset requirements for builders (Vickers 2001). At a minimum, 11 regulatory mechanisms ought to be established statewide.
B. Educational. It is critical that the State fund DNR’s Statewide Water Conservation Program to lead comprehensive education and technical programs statewide to help create public awareness and a conservation ethic. Public understanding and support are critical to the ultimate success of a statewide water conservation plan, because changing behaviors is key to affecting water demand management. Educational outreach and technical assistance should target both public and private sectors and address Georgia’s water supply condition, water efficiency devices (hardware that provides better or same level of service with less water), wise water-use or water conserving behaviors, and curtailment (certain water uses limited or prohibited) and alternative supplies such as water recycling, rainwater harvesting, and wastewater reclamation and reuse. The state should set a benchmark for a percentage of citizens to be reached in a certain period of time. Coordination and partnerships with governmental agencies (P2AD, ARC, DCA, GEFA, and SWCC), local water providers, and non-profit organizations will be essential to the programs success. Examples of educational outreach should include direct-mail literature, bill inserts, redesigned bills that include historical water consumption information, television and radio advertisements, demonstration gardens and projects, school curricula, and conservation checklists for permitees (Vickers 2001). C. Financial. A variety of financial incentives exist that local governments can use to provide financial relief. For example, conservation pricing can provide needed funds for such programs as rebating or replacing old plumbing fixtures. Two regulatory incentives previously mentioned, address rebate programs for retrofitting old plumbing fixtures and conservation rate structure pricing. Other examples include bill credits, surcharge fees, cost-sharing with other utilities and businesses, and performance contracting (contractor compensation based on water savings achieved) (Vickers 2001). VII. Strategic Measures for Water Conservation and Reuse in Georgia Measures, or “tools”, include hardware and technology or the behavior associated with hardware and technology that reduce the amount of water a particular use consumes. A total of 5 general measures, at a minimum, should be promoted throughout Georgia.
VII. Our Future Depends Upon Water Conservation The development of a comprehensive Water Conservation Plan through the statewide water planning process can get Georgia where it needs to be if the plan utilizes a range of mechanisms (regulatory actions, education and technical programs, and financial incentives) and measures that reduce water consumption and demand. Water conservation and the efficient use of existing water supplies must always be treated as the highest priority in planning to meet the needs of Georgia’s citizens and ecosystems prior to increasing water supplies. Comprehensive water conservation planning has the potential to improve water quality and instream flow levels, decrease the need for new capital investments, reduce vulnerability to drought, and provide additional benefits to people and ecosystems. The Georgia DNR and the public must be committed to protecting the integrity of Georgia’s aquatic resources for the longterm benefit of humans and other species. Healthy, naturally functioning rivers, streams, wetlands, aquifers, and estuaries are vital to all life and to the state’s economic success. Now is the time to shift the current water supply paradigm from trying to increase a finite supply to reducing our excessive demand. Now is the time for our citizens, state and local governments, as well as the private and industrial sectors, to make a commitment to conserve surface and ground waters by reducing our water consumption, by supporting water reuse and recycling, and by providing economic incentives to sustain the health of our population, our economy, and our ecosystems.
