Manage, operate and maintain the Cary/Apex Water Treatment Plant and associated facilities which are capable of producing water to meet peak day use of 40 million gallons per day (MGD). 2. Maintain compliance with all state and Environmental Protection Agency (EPA) drinking water regulations. 3. Produce a safe, high quality and aesthetically pleasing supply of drinking water for Cary and Apex water customers. 4. Perform laboratory analyses of treated water for Cary and Apex water customers. 5. Perform preventive and corrective maintenance for the Cary/Apex Water Treatment Plant, Jordan Lake raw water pump station, and two Town of Apex flow transfer vaults. 6. Operate a water treatment pilot plant program, a scaled down version of the plant, as needed to allow for process control optimization, treatment strategy development and testing of various system configurations. 7. Prepare and plan for future capital facilities needs of the Cary/Apex Water Treatment Plant and associated facilities. 8. Foster and maintain good relationships with the surrounding community through communication and by managing facility aesthetics. Residuals Management 9. Manage the processing and recycling of water treatment residuals, a type of sludge or waste product currently being recycled with a local composting facility. ACCOMPLISHMENTS Achieved compliance with all state and EPA drinking water standards and regulatory requirements. Certified for the tenth consecutive year as a Partnership for Safe Water Director s Award facility. 1,3,5,6 7 8

19 Completed the design phase and began construction of the Phase III Expansion Project which will be the next capital facilities expansion at the plant and increase water production capacity to 56 million gallons per day. Completed a plant-wide control system upgrade including upgraded Supervisory Control and Data Acquisition (SCADA) system and upgraded Programmable Logic Controller (PLC) and fiber optic communications networks. This upgrade was the first stage of the Phase III Expansion project. Completed the second distribution of the Town s Annual Water Quality Report to all Utility customers utilizing an electronic distribution format. The change to electronic distribution allows the Town to save approximately $20,000 annually in report distribution costs. Completed an asset inventory of all critical equipment and assets at the water treatment plant and associated facilities.
