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: Construction commenced on the project in May 2014 and is estimated to be complete in winter 2017.

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 summer 2018.

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 in close proximity to one another.  The final design stage has been completed and easements have been obtained.  The project has entered into the final permitting stage.

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. 

Schedule: The Globe Road interconnection is in the final design stages with easements being obtained by the City of Raleigh. Construction is anticipated to begin in fall 2017 and be completed in summer 2018.

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 Western Cary/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 segments of neighborhoods along the Davis Drive corridor and westward to NC 55 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. For homes and businesses with a functional pressure reducing valve (PRV), we do not anticipate any problems as a result of this pressure change.

Zone Change Map

Schedule:

Tank: The water storage tank is officially under contract with CB&I, however site work will not begin until fall 2017. Construction is anticipated to be completed by summer 2019.

Pressure Zone: Beginning summer 2017 and 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 int the CPZ by the time the new tank is complete will be transitions shortly after the tank come online in summer 2019.
