2 0 1 9 W A T E R Q U A L I T Y R E P O R T 3 Cary invests millions of dollars each year to upgrade aging or underperforming piping and valves. We developed an asset management plan to focus attention and resources efficiently on the condition of these assets and replacing them as needed. DISTRIBUTION SYSTEM INFRASTRUCTURE Our water treatment facility expansion to 56 million gallons per day (mgd) was completed in 2018. Anticipating future needs, we completed the new Kilmayne tank in central Cary in 2018, and our new Good Hope Church Road tank was completed in 2019. Together, these two new tanks provide four million gallons of additional water storage. In 2019, we rehabilitated the Maynard tank (across from Cary High School). To enhance water system resiliency, Cary partnered with the City of Raleigh to complete construction of a new emergency interconnection on Globe Road, near RDU Airport, and a second emergency interconnection with Raleigh near Crossroads is underway with estimated completion in early 2021. MEETING DEMAND The State awarded Cary an increased water allocation from Jordan Lake based on our anticipated needs through 2045, ensuring an adequate water supply to our community. WATER SUPPLY Cary's water tanks and pipes help to maintain consistent water pressure. Because of topography, Cary's water system is divided into three pressure zones. Over the past year, we shifted a number of neighborhoods between Davis Drive and NC 55 from the Western Pressure Zone to the Central Pressure Zone, which increased pressure for those homes and business. The shifts were accomplished over 18 months and were completed in April 2019. SYSTEM PRESSURE WATER SYSTEM RESILIENCY Cary is committed to delivering safe, reliable, high-quality water to support our community. Here are some ways Cary enhanced water system resiliency in 2019.
