Cary/Apex Water Treatment Facility - Phase 3 Expansion (CAWTF)

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.

Cary/Apex Water Treatment Facility-Phase 3A Improvements

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.

Cary/Raleigh Water Supply Interconnection Project

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 has been completed and all permits and easements have been obtained. 

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 Tank and Pump Station Project. 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 Update, Spring 2019:  The Phase II (Globe Road) project was publicly bid and awarded to Pipeline Utilities, Inc. A Notice to Proceed with Construction was issued for the work to start fall 2018 and is now approximately 80 percent complete. Work is expected to end May 2019.

An updated Mutual Aid Agreement is currently being written to reflect project changes, and will be presented to Council by fall 2019.

Good Hope Church Rd. Water Storage Tank

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.

Schedule

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.

Wimberly Road Water Line and Western Cary Water Main Improvements

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.
