Overview: This project provides for the engineering evaluation, analysis, design and construction for future expansion and improvements of the Cary/Apex Water Treatment Facility beyond its current capacity of 40 million gallons per day (MGD), and to maintain adequate infrastructure. According to a preliminary engineering report completed in April 2010, the most cost-effective expansion would increase the CAWTF capacity to 56 MGD. Design and permitting of the project were completed in January 2014.
Schedule: Project completed in fall 2018.
Status: This project is being completed with two construction contracts. There is a contractor completing improvements to the systems at the CAWTF site. This work includes expansion of the administration building and the various water treatment processes necessary to produce 56 MGD of treated drinking water.
A separate contractor completed the expansion of the Raw Water Intake Structures and Pump Station at Jordan Lake. To meet the increased water demands, new pumps and larger intake structures are required. This portion of the project was completed in summer 2016.

Overview: The Cary/Apex Water Treatment Facility (CAWTF) uses concrete process basins with ancillary electrical and mechanical equipment for core treatment processes. This project provides funding for the restoration of the plant’s original and Phase I expansion process basins and equipment which date to 1993 and 2001, respectively. Routine wear and tear on the process basin infrastructure results in the need for periodic restoration and rehabilitation. This project will also study the potential benefits of converting the existing chemical filtration process to a biological filtration process. A potential benefit of biofiltration is reduced operational costs for water treatment. This project also provides funding for an additional clearwell at the CAWTF.
Schedule: Work by consultants on a study and preliminary engineering report is underway and is anticipated to be complete in spring 2019.

Overview: The City of Raleigh and the Town of Cary have developed a mutual aid agreement that includes providing interconnections between the two water systems at strategic locations with the capability to move water in both directions. This regional approach to contingency planning will provide both municipalities with additional options in the event of a drought, unexpected issues at a treatment plant, or any other single point vulnerability along a transmission line. The Town already has a similar agreement and interconnections with the City of Durham.
Description: The initial phase of the project was completed in the summer of 2015. It included the transfer of the Holly Springs Rd water line from Raleigh to Cary and modifications at the Town's Trinity Road Booster Pump Station.
A second phase of the project is planned to create an interconnection along Globe Road where the two water systems are near one another. The final design stage has been completed and all permits and easements have been obtained. The project was awarded and a notice to proceed to construction is anticipated soon.
A third phase of the project was originally planned to provide an interconnection along Jones Franklin Road and another along Tryon Road. These two interconnections will now occur as part of the Crossroads Ground Storage Tank Project. For updates on the third phase (Jones Franklin Road and Tryon Road Interconnections) please refer to the Crossroads Ground Storage Tank Project update. An amendment to the mutual aid agreement to reflect these changes is currently being drafted and reviewed by the Town of Cary and the City of Raleigh.
Status: The Phase II project was publicly bid and awarded to Pipeline Utilities, Inc. A Notice to Proceed with Construction was issued for the work to start on or before October 1, 2018. Construction is anticipated to be completed in early 2019.
An updated Mutual Aid Agreement is currently anticipated to be approved by Town Council at the November 15th Council Meeting.
The design of the third phase is currently under design and is anticipated to be advertised for bid fall 2019.

Overview: In 2016, the Town established a five-year project to improve locating, mapping and inspection of water system infrastructure in critical water transmission corridors. The corridors selected have older, non-metallic water lines, which can be difficult to locate, and serve large residential and commercial areas.
The corridor for FY 2019 is SE Maynard Road from Walnut Street west to East Chatham Street.
Past corridors include:
- Kildaire Farm Road from SE Maynard Road to Tryon Road
- Holly Springs Road from Jones Franklin Road to High Ridge Drive
- Walnut Street from Buck Jones Road to Cary Towne Boulevard
Schedule: Work for the FY 2019 corridor, SE Maynard Road from Walnut Street north to East Chatham Street, begins Monday, July 30 and is expected to be complete in eight weeks.
Overview: This project provides for the design and construction of a 3.1 million gallon water storage tank, related booster pump station, and interconnections with the City of Raleigh to be located in the vicinity of the Crossroads shopping center.
This infrastructure will add needed Central Pressure Zone (CPZ) water storage and facilitate the transfer of water between the City of Raleigh and the Town of Cary’s central and southern pressure zones. In addition to providing additional water storage, operational flexibility, resiliency and redundancy in our utilities system, this project includes important interconnections between Cary and Raleigh so emergency water transfers can be made and exchanged safely and reliably.
Schedule: Preliminary engineering work is completed. Final design and permitting has begun. The project is slated to begin construction in fall 2019 and should last until spring 2021.
Public Open House: Working in cooperation with the City of Raleigh to find regional solutions for our utilities, the Town of Cary held an open-house style public meeting Tuesday, September 19, 2017 from 6:30 - 7:30 p.m. at Dillard Drive Elementary School where Cary and Raleigh staff answered project questions as guests viewed preliminary design options for the tank.
We look forward to talking with you about this exciting project and encourage you to stay informed by checking this web page for updates.

Overview: The Good Hope Church Rd. Water Storage Tank Project consists of a 2 million gallon elevated water storage tank and pump station located near the intersection of NC Highway 55 and Good Hope Church Road. In order to distribute the water from the tank and strengthen the piping network, water lines along NC 55, Jenks Road, Hortons Creek Road and other locations will be installed. In addition, the pressure zone boundary between the western and central pressure zones will be modified.
When the Western Pressure Zone (WPZ) was first created, both Cary and the water distribution system looked much different. Over the past 13 years, the Town's water system has experienced significant changes such as the merger with the Town of Morrisville's water system and the growth and expansion of the pipe network in the western part of town. These two key elements now make it possible to return most properties east of NC 55 to the higher, Central Pressure Zone (CPZ).
When completed, the Good Hope Church Road Water Tank will provide additional storage for the water system, help maintain system pressure, reduce the demand on the transmission mains during peak flow conditions, and provide reserve capacity during firefighting or system maintenance activities. The pump station will allow water transfers to the CPZ where demand is increased due to the boundary modification. The pressure zone modifications will maximize operational efficiency and increase water pressure for over 6,000 properties.
Pressure Zone Modifications
Beginning summer 2017, incremental sections of neighborhoods along the Davis Drive corridor and westward to NC 55 (defined by orange boundaries in the map below) will be transitioned from the current WPZ into the CPZ. This change will result in an increase of 40 pounds per square inch (psi) in the municipal water pressure throughout the designated area. Search your address on the map below and find out if your property is participating and get pressure zone modification project details, including what to do if your property is within the boundary.
For homes and businesses with a functional pressure reducing valve (PRV), we do not anticipate any problems as a result of this pressure change. Call (919) 469-4090 or submit a request if you would like assistance identifying whether you have a PRV and what your current water pressure is.
Tank: As the construction of the tank is completed in late 2018, work will continue on the site with the construction of the pump station. The work is on schedule to place the tank into operation by summer 2019.
Pressure Zone: Through spring 2019, we will notify property owners by mail as we gradually transition properties from the WPZ to the CPZ. Any areas not shifted into the CPZ by the time the new tank is complete will be transitioned shortly after the tank comes online in summer 2019. The next areas to return to the central pressure zone are in the Carpenter Village and Twin Lakes areas this December, followed by the Preston Village area in the spring.

Overview: This project provides for the installation of an interconnection between two dead-end, 12-inch water lines located on Towerview Court. The two dead-end lines are fed from opposing directions and terminate approximately 80 feet apart. Once the interconnection of the two-dead end 12-inch water lines is complete, the portion of the existing 12-inch water line extending west of Towerview Court will be connected to an existing 24-inch water line, which runs parallel to NW Cary Pkwy. The completion of these interconnections will create a continuous water service loop in the area, providing greater redundancy in the event of a water line break or other outage. The connection will also aid during times of high demand flows such as firefighting.
Schedule: Construction of the project is complete. A one-year warranty inspection for the project will occur in fall 2019 and any issues identified during the warranty inspection will be corrected by the contractor, North State Water and Sewer.

Overview: The Wimberly Road water line will ensure adequate water supply in northwest areas of Cary while improving the reliability of the distribution system by providing an additional feed from the water treatment facility. The project includes 8,500 feet of 36-inch pipeline along Wimberly Road between the Cary/Apex Water Treatment Facility (CAWTF) and Green Level West Road. An additional 3,500 feet of 16-inch pipeline will be constructed along Green Level West Road between Green Level Church Road and NC Highway 540. In this same vicinity, 1,900 feet of 12-inch water line will be installed between NC 55 and Roberts Road to maintain water quality and eliminate dead ends.
For similar reasons, the existing water lines to the north along Hortons Creek Road and Highcroft Drive are being connected under NC 540. This 2,100 foot segment will be a 20-inch diameter pipe. In order to move water out of the new Good Hope Tank that is being constructed, 2,900 feet of 16-inch water main will be constructed from Good Hope Church Road to Carpenter Fire Station Road along NC 55.
To increase the resiliency of the overall water distribution system, three emergency connections are being installed along the NC 55 corridor. These will allow the flow of water from the central pressure zone (east of NC 55) back into the western pressure zone (west of NC 55). These connections are strategically placed near Jenks Road, Green Hope School Road and Kit Creek Road. These facilities will be almost entirely below ground and controlled remotely.
The final element of the project is to establish NC 55 as the clear boundary between the pressure zones. To achieve this and simplify system operations, we will be making modifications to the existing water lines between Jenks Road and Connemara Drive along the NC 55 corridor. These changes have been designed so that there are no interruptions in water service. Should that change due to unforeseen conditions, property owners will be promptly notified. As work will be taking place in and around the intersections through this corridor, we urge motorists to be on the lookout for temporary lane closures.
Schedule: Construction began in summer 2018 and is expected to be completed by the end of 2019.
