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.

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 10 Town of Cary residences.

Schedule:
 Final design work has been completed and the Town is working through the permitting process. All permits have been submitted and received with the exception of a NC Department of Transportation agreement to work within the Tryon Road Right-of-Way. Conversations with NCDOT suggest that this agreement is anticipated to be received in the next week or two, allowing bidding to occur in June. Construction is anticipated to begin in summer 2017 with the water and sewer lines complete and in-service by winter 2018.

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.
