2 0 1 7 W A T E R Q U A L I T Y R E P O R T 3 The Town invests millions of dollars each year to upgrade aging or underperforming piping and valves. The Town 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 Construction is nearly completed to expand our water treatment capacity from 40 million gallons per day (mgd) to 56 mgd. Anticipating future needs, the Town is constructing two new elevated storage tanks with a combined four million gallons of additional storage — the Kilmayne tank in central Cary and Good Hope Church Road tank in western Cary. During this next year, we will be rehabilitating the Maynard tank (across from Cary High School). A new ground storage tank near Crossroads is projected to be in service by 2021, providing an additional three million gallons of storage along with an improved emergency interconnection with Raleigh. MEETING DEMAND The State awarded the Town increased water allocation from Jordan Lake based on our anticipated needs through 2045, ensuring adequate water supply to our community. WATER SUPPLY The Town's water tanks and pipes help to maintain consistent water pressure. Because of topography, the Town's water system is divided into three pressure zones. Last year, the Town began shifting neighborhoods between Davis Drive and NC 55 from the Western Pressure Zone to the Central Pressure Zone; as a result, pressure will increase for those homes and business. This shift is expected to continue in phases through 2019. SYSTEM PRESSURE WATER SYSTEM RESILIENCY The Town of Cary is committed to delivering safe, reliable, high-quality water to support our community. Here are some ways Cary enhanced water system resiliency in 2017.
