In the fall of 2024, work will get underway to rehabilitate sewer lines and manholes in four locations within Cary’s wastewater collection system, as described below. Sewer line rehabilitation will be accomplished primarily by the installation of cured-in-place pipe (CIPP) liners, a “trenchless” method of upgrading sewer lines that Cary has used successfully for over 20 years. 

Brier Creek Interceptor

Over the last couple years, Cary’s sewer rehabilitation program upgraded the large diameter sewer lines (often referred to as “interceptor sewers”) along the east side of Lake Crabtree along the Crabtree Creek and Black Creek Greenway Corridors.  Following the successful completion of that project, we are focusing our efforts on the large sewer pipeline along the west side of Lake Crabtree.  This portion of the project will upgrade 1.5 miles of 36-inch and 42-inch pipe and is expected to take one year to complete.  This work will be completed in two phases, split at Aviation Parkway.  This critical sewer pipeline serves a significant portion of the Airport and Aviation Parkway corridors in Morrisville, site developments along McCrimmon Parkway, commercial and industrial sites adjacent to the west side of Lake Crabtree and the Raleigh-Durham International Airport (RDU).

McCrimmon Corners

Work in the McCrimmon Corners area, near the intersection of Davis Drive and McCrimmon Parkway, involves rehabilitation approximately 2,000 feet of corroded ductile iron sewers along Madison Heights Way.  A portion of this work will be completed at night to minimize impacts to businesses and their customers.

Lochmere Drive Area

The Lochmere Subdivision includes three lakes.  Two of these lakes – Lake Lochmere and Lake Lomond have sewer lines crossing through the dams.  This project will rehabilitate 1400 feet of 8-inch and 12-inch sewer lines to maintain the structural integrity of sewer system infrastructure within and adjacent to the dam at Lake Lomond (the smaller of the two lakes adjacent to Lochmere Drive). Sewer lines in the vicinity of the Lake Lochmere Dam (a.k.a. " the big lake") were previously rehabilitated under a recent project.

Cary Towne Boulevard

The sewer line along Cary Towne Boulevard adjacent to the former Cary Towne Center property receives flow from multiple businesses west of SE Maynard Road as well as the Esat Cary Magnet Middle School and the Henry Adams Elementary School.  Rehabilitation of this sewer line is imperative to providing reliable sewer service.

This project is scheduled to begin in the fall of 2024.  The overall project is expected to take 1.5 years to complete.

October 2023: The sewer rehabilitation work along the Black Creek Greenway and at the Old Reedy Creek Trailhead has been completed. Contractors are currently working to remove temporary above-ground piping and perform cleanup and restoration items along the project corridor. This work is scheduled to be completed this fall.

February 2023: The Black Creek Greenway between Dynasty Drive and North Cary Park opened to the public while rehabilitation of sewer lines and manholes took place along the Black Creek Greenway from North Cary Park to the Crabtree Creek Greenway. The trail was closed in this area with a signed detour in place to route greenway traffic around the work zone. This work is was completed later in the spring.

The final phase of the project began near the fork where the Black Creek Greenway and Crabtree Creek Greenway intersect, continuing along the Black Creek Greenway toward the trailhead at Old Reedy Creek Road. Special construction mats were placed adjacent to the Black Creek Greenway near the trailhead in preparation for sewer rehabilitation along this section of trail, which was scheduled to begin late Spring/early Summer 2023. No greenway closures were scheduled for this final portion of the project, but trail users were advised of the potential for trucks and equipment crossing the greenway at the trailhead.

August 2022: The Crabtree Creek Greenway opened to the public. Some final repair items remain, which were able to be completed without the need to have the greenway closed. We sincerely appreciate the public’s support and understanding while these important sewer upgrades were being completed along the Crabtree Creek Greenway. As of this completion, work shifted to along the Black Creek Greenway from West Dynasty Drive to North Cary Park and this portion of the Black Creek Greenway was closed for the safety of the public and construction personnel. A signed detour was in place to direct greenway traffic around the work zone.

June 2022: The first phase of the Crabtree Creek & Black Creek Sewer Rehabilitation Project approached completion. Liners were installed in the large diameter sewer line along Crabtree Lake, with manholes repaired and cleanup/restoration activities performed before reopening the Crabtree Creek Greenway.

In the next phase, contractors will focus their efforts on rehabilitation of sewer lines along the Black Creek Greenway between West Dynasty Drive and North Cary Park, which will require a closure of this section of greenway. The remaining parts of the Black Creek Greenway, including those areas between North Cary Park and the Crabtree Creek Greenway will remain open during this phase of the project.

December 2021: The contractor mobilized to the site in early November 2021. A temporary construction entrance was built off Evans Road, and temporary piping used to reroute sewer flows was assembled. Construction entrances were built at other key locations along the Crabtree Creek Greenway corridor.

August 2021: Contract has been awarded; work was scheduled to begin along Lake Crabtree the fall.
