Projects



Carystone Pump Station Elimination

Overview: This project provides for the elimination of the Carystone Pump Station through the installation of approximately 950 linear feet of new 8-inch gravity sewer. This new gravity sewer will eliminate the pump station and tie to the existing sewer on W. Chatham Street. The intent of this project is to eliminate the need for a sewer pump station to remain on the Town of Cary System. Pump stations require constant maintenance and power to operate. The new gravity sewer will involve a lot less maintenance by Town of Cary Department of Public Works. The residents of the nearby neighborhoods will no longer see the above ground pump station and will not be affected by any lingering odor problems.

Schedule:
 Construction will begin in fall 2017.

Jack Branch Interceptor Project (SW1269)

Overview: This project provides for the extension of the existing interceptor sewer system located near Jack Branch and approximately 1,000 linear feet west of the I-540 Toll Road in accordance with the Town’s Wastewater Collection System Master Plan. The extension will be located adjacent to the Jack Branch and extend to the east approximately 4,500 linear feet. The total length and actual location of the extension will be based on available funding and will be determined after the design phase is complete. 

This projects extends gravity sewer to the service area east of I-540, west of NC55 and north of Jenks Road. This area is currently not served by the Town’s sanitary sewer system. 

Schedule: Survey is underway, design is scheduled to begin in summer 2016, easement acquisition is scheduled to begin spring 2017 and construction is scheduled to begin in spring 2018.

Lower Swift Creek Parallel Sewer

Overview: This project supports easement acquisition, design and construction for 3,500 linear feet of 30-inch and 8,700 linear feet of 24-inch sewer lines parallel to the existing Swift Creek interceptor. The 30-inch segment will run from the existing Swift Creek pump station to Lochmere Golf Course, while the 24-inch segment will run through the Lochmere Golf Course westward to Kildaire Farm Road.

Schedule:
 The Town is currently conducting a study of the physical condition and capacity of existing Swift Creek Interceptor. Once complete, the study will recommend improvements needed to alleviate any short-term surcharging conditions as well as total build-out flow projected under wet weather conditions.

MacGregor Pump Station Elimination

Overview: This project provides for the elimination of the MacGregor Park Pump Station through the installation of approximately 300 linear feet of new 8-inch gravity sewer. This new gravity sewer will eliminate the pump station and be bored and jacked under US Highway 1 and connected to an existing Town of Cary 8-inch ductile iron pipe. The intent of this project is to eliminate the need for a sewer pump station to remain on the Town of Cary System. Pump stations require constant maintenance and power to operate. The new gravity sewer will involve a lot less maintenance by Town of Cary Department of Public Works.
Schedule: Construction will begin in spring 2017.

North Cary Water Reclamation Facility Re-Rating & Aeration Improvements

Overview: This project provides for the engineering evaluation, analysis, design and construction of aeration improvements at the North Cary Water Reclamation Facility (NCWRF).  The ‘North Cary Water Reclamation Facility Capacity Analysis and Plant Evaluation’ report, completed in 2016, recommended supplemental aeration improvements and re-rating the NCWRF to a permitted capacity of 13.5 million gallons per day.  These improvements are the most cost-effective means to allow for greater treatment capacity while efficiently maintaining the plant’s current level of high quality effluent.

Status:
Preliminary design work is expected to begin in spring 2017.

Paramount Pump Station Elimination

Overview: This project provides for the elimination of the Paramount Pump Station through the installation of approximately 3,000 feet of 12-inch gravity sanitary sewer. Abandoning the existing pump station will avoid the need for future pump station and force main maintenance and upgrades. In addition, the proposed gravity sewer will help alleviate wastewater capacity issues in the Perimeter Park basin.

Schedule:
 This project is currently under design. Construction is estimated to begin in summer 2017.

Pink Acres Street Water and Sewer Extension

Overview: The Pink Acres Street Project consists of providing water and sewer service to the Pink Acres Street community, along Pink Acres Street and Tryon Road. The community petitioned the Town of Cary to receive water and sewer service. The project was subsequently approved by Council in December 2014. The residents of the Pink Acres Street community currently utilize private well and septic systems. This project, when completed, will provide approximately 950 feet of sewer mains, 800 feet of water mains, one fire hydrant, water and sewer services, and additional fire protection to approximately 12 Town of Cary residences.

Schedule:
 Detailed design work is underway. Construction is anticipated to begin in summer 2016.

Sewer Rehabilitation 

Overview: Cary’s wastewater collection system is comprised of more than 800 miles of gravity sewer lines and over 24,000 manholes. The Town budgets for renewal of this infrastructure as it ages to continue providing dependable wastewater collection to its customers. Sewer lines are typically renewed through the insertion of a resin-impregnated flexible lining, that, when cured, forms a new “pipe-within-a-pipe.” This process, referred to as cured-in-place pipe, improves the flow characteristics of the sewer pipe and reduces costly maintenance needs by eliminating any gaps, cracks or structural defects that could enable groundwater infiltration, root penetration and reduces the likelihood of debris or sediment accumulation.

Manholes are rehabilitated by first cleaning the manhole and removing any loose material, then applying a specially-formulated grout that is stronger and more resistant to corrosive sewer gases than conventional manhole construction materials. In cases where corrosive gases are more concentrated, a topcoat of epoxy is applied to the inside of the newly rehabilitated manhole.

During the time that sewer rehabilitation work is in progress, sewer service may be interrupted for short periods of time, typically less than eight hours. Customers impacted by this work will be notified approximately 72 hours in advance of the service interruption. While we apologize in advance for the disruption, the rehabilitation of sewer lines and manholes is far less disruptive than traditional excavation and installation.

Wastewater Pump Station Parallel Force Mains

 

 

 


 

Overview: This project includes the design and construction of new force mains to provide redundancy to existing critical force mains. Parallel force mains will be constructed for the Walnut Creek Pump Station, Blanche Drive Pump Station, Jones Franklin Pump Station, Aviation Parkway Pump Station and the Talloway Pump Station. Additional pump stations may be added as the project progresses. These new force mains will make it possible to take the existing force mains down for preventative maintenance and cleaning, as well as provide additional operational flexibility to the system.

Schedule: Construction of the Walnut Creek, Jones Franklin and Blanche Drive Parallel Force Mains is complete. The Aviation Parkway and Talloway Force Mains are under design, with construction anticipated to begin in early 2017.
