3 The Water Division has been teaching water conservation to elementary school students for more than years. In 5, the division held our second annual Water Festival at the Orlando Science Center for over seventh-grade students. The Water Festival focused on helping students understand the various stages of drinking water supply and treatment. This year s festival was a partnership with other agencies and covered topics such as the weather, the production and distribution of water, the quality of surface water and potable water and the need to conserve this valuable resource. Orange County continues to work diligently on solutions to meet the water needs of our growing community while protecting the area s quality of life for future generations. These solutions stem from an integrated approach to the use of all water resources and include increased water conservation, the use of highly treated reclaimed water and storm water where possible for irrigation, and the development of new water resources, which will include surface waters like the St. Johns River. The laboratory and microscopic analysis activity allowed students to get the hands-on experience of using microscopes. Students explored several of the different tests used to assess the quality of the water they drink. With the use of an interactive model, the water production process was explained including pumping raw water from the ground, the stages of treatment and the distribution of water to homes. Students found out how hard it is to manually pump water with the Pump Till It Runs Dry contest. Students pumped water into paper cups and transported it into their container. The team that produced the most water won the activity. CCR Eastern.pmd 3 Water is one of our most precious and valuable resources but we don t often pause to consider the tremendous value of a safe, reliable water supply and the water system that delivers it in our everyday lives. Any measure of a thriving society low mortality rates, economic diversity, productivity and public safety is, in some way, related to access to safe water. Orange County is a thriving community and some credit can be attributed to its safe and dependable supply of drinking water. The St. Johns River flows over 3 miles from Indian River County through Orange County and orth to Jacksonville. It is enjoyed by many Floridians for recreation, fishing and bird watching. Orange County Utilities is working with engineers and scientists on a water supply project that preserves all of these natural elements and makes water available to us for future growth. The plan that is currently in development includes withdrawing water from the river during high flows when plenty is available and storing it for later use. When needed, the water would be treated to meet state and federal drinking water standards and distributed to water providers throughout the region. This regional plan will define how much water is available, the treatment requirements and how to distribute the water to the citizens of Orange County and surrounding areas. Orange County Utilities will continue to cooperate with our neighbors on water resource development that is environmentally sustainable. 3 5/3/, 7: AM

4 About Your Water Utility Orange County Utilities water system continues to provide reliable service to a growing number of customers in Orange County. In 5, the Orange County Utilities Water Division provided quality water service to over 3, accounts, serving a population of more than 3,, which represents an increase of almost 8% over the previous year. We produced.5 billion gallons of water in our two regional water facilities and smaller facilities. The water was distributed through,55 miles of water mains throughout the square mile service area. 5 EPA Safe Drinking Water Act Excellence Award Winner The Orange County Utilities Eastern Regional Water Supply Facility was the recipient of the EPA s prestigious 5 Safe Drinking Water Act Excellence Award in the Large Groundwater System category. The Excellence Award recognizes water systems that demonstrate a commitment to compliance with the Safe Drinking Water Act through outstanding operations and maintenance practices. Orange County Utilities takes pride in ensuring a safe and adequate supply of drinking water for our customers. Source Water Assessment and Protection Program (SWAPP) SWAPP stands for Source Water Assessment and Protection Program. This program is meant to ensure that your drinking Water Division is a 5 Platinum Award Winner! water is safe, not just at the tap, but at its source. The Florida Department of Environmental Protection (FDEP) is initiating SWAPP as part of the federal Safe Drinking Water Act (SDWA). The Association of Metropolitan Water Agencies (AMWA) presented Orange County Utilities with its 5 Platinum Award for Competitiveness Achievement. The AMWA Platinum Award recognized Orange County for continuing to apply best management practices to meet the public s requirements for safe water and low-cost service. The water that surrounds us lakes, rivers, streams and aquifers makes up our drinking water sources. These source waters can be threatened by potential contaminants such as hazardous chemicals, stormwater runoff, waste disposal sites and underground storage tanks. It is a national priority to protect these sources and ensure safe drinking water for citizens. SWAPP was created to protect these vital resources. Technological and organizational strategies help the Orange County Utilities Water Division maintain its competitive edge. Major technological accomplishments include a state-of-the-art laboratory and technologically advanced automation and information systems including a computer control center that is staffed /7 to monitor and maintain plant operations, and a wireless Computerized Maintenance Management System that has allowed field staff to process work orders more efficiently. The Florida Department of Environmental Protection is undertaking a baseline program to assess any threats to drinking water supplies. FDEP has completed the initial baseline study for our water systems and results are posted on the SWAPP website ( Since initial evaluation is based on existing databases, FDEP can only make preliminary and tentative evaluations. Changes that are reported can help update the databases and provide timely information. Community members can help by reviewing the information and reporting any discrepancies that are identified.

5 Assurance of Healthy Drinking Water The Environmental Protection Agency (EPA) requires all public water suppliers to routinely monitor for constituents in the drinking water according to federal and state laws. The state allows us to monitor less than once per year because the concentrations of these contaminants do not change frequently. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some constituents. The presence of these constituents does not necessarily indicate that the water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA Safe Drinking Water Hotline at In order to ensure that tap water is safe to drink, the EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water that must provide the same protection for public health. The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly and infants can be particularly at risk for infections. These people should seek advice about drinking water from their health care providers. EPA and the Center for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbiological contaminants are available from the EPA Safe Drinking Water Hotline at Contaminants that may be present in the source water include: Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife. Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining or farming. Pesticides and herbicides, which may come from a variety of sources, urban storm water runoff and residential uses. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff and septic systems. Radioactive contaminants, which can be naturally occurring or be the results of oil and gas production and mining activities. To Distribution System Aeration Well Pumping Air Quality Control Sulfide Removal CO Addition Chlorine Addition Fluoride Addition ph Adjustment Well pumps at Orange County s water supply facilities draw water from a natural underground reservoir called the Floridan A quifer. After being treated with chlorine, fluoride is added and the water is pumped to a finished water tank, awaiting distribution to residential, commercial and industrial customers. Your Water Supply Source Beneath Orange County lies a fresh water reservoir known as the Floridan Aquifer. The groundwater from this aquifer is of consistently high quality and is used as a source of potable water for our systems and other systems in this area. It is primarily fed by rainwater that is filtered through hundreds of feet of sand and rock in a natural filtering process. Because of its high quality, the groundwater we use needs little or no treatment other than disinfection and aeration to remove hydrogen sulfide. Ways to Protect Your Drinking Water By taking some simple steps in your home or community, you can play a part in protecting our drinking water sources. Make it a point of duty to: Dispose of household and other chemicals properly. Don t pour chemicals on the ground or down the sink drain, toilet or storm drain. Take used motor oil to the recycling center. Use only recommended amounts of fertilizers and pesticides. Have your unused wells properly closed. Pump and inspect your septic tank regularly. Plant vegetation on bare spots of soil, particularly on slopes. This will prevent erosion and excessive runoff of sediments into nearby water bodies. Become involved in drinking water protection activities in your community. 8 CCR Eastern.pmd High Service Pumping Transfer Pumping 5 5 5/3/, 7:3 AM
