Town of Clayton Water Reclamation Program

Updates

Progress at the Sam’s Branch WRF has moved along nicely with the completion of all the round tanks (including setting the domes on top), erecting structural steel for various structures, pouring concrete for the Headworks, Bioreactor (BNR), and Influent Pump Station (IPS), and placing structural block and roof on the Administration Building. Thalle Construction, the General Contractor for the project, hit a major milestone when the IPS structure was poured and hydraulic tested to hold water. The structure passed the test and now subsequent linework and backfill of the large pit can resume. The concrete subcontractor, Donley’s, has placed 9,000 cubic yards of concrete to date, which equates to roughly 36,000,000 pounds of concrete and rebar. The Administration Building, built by Muter Construction, has progressed with the construction of the interior walls, HVAC, plumbing, and electrical systems. Once the split-faced block arrives, masons will finish the façade of the Administration Building. Roberts, the Electrical subcontractor, placed electrical duct bank sitewide and has begun terminating the conduits in the Electrical Building South (one of the two electrical buildings for the project).

In the coming months, the BNR structure, which is the largest of the project, will be completed and hydraulic tested. Following a successful test, process piping will be installed in the structure. We will see Muter continue to go vertical with structural steel and block on the two-story Thickening and Dewatering Building. Thalle pipe crews will continue to install yard piping that will convey the wastewater to the different treatment structures. Roberts will continue to place electrical duct bank and associated work in the two electrical buildings.

The ongoing transmission improvement project entails several key components. These includes the installation of a new 24-inch force main, connecting the existing Little Creek Water Reclamation Facility to the gravity discharge point on Front Street. 

This endeavor involves the complex task of boring and jacking beneath critical areas such as US-70, Front Street, and the NCRR railroad tracks. 

Furthermore, the project encompasses the establishment of a new gravity sewer, ranging from 24 to 48 inches in diameter, connecting Front Street to the future influent pump station for the Sam's Branch Water Reclamation Facility. 

The esteemed general contractor for this project is JF Wilkerson, while the Town's designated engineer of record is Withers & Ravenel.  

One of the vital project elements currently in the construction phase involves the creation of a cutting-edge pump station with an impressive capacity of 13 MGD. This station is designed to redirect flows from the established Little Creek Water Reclamation Facility to the recently developed Sam's Branch Water Reclamation Facility.

The new pump station will be equipped with state-of-the-art submersible pumps, advanced odor control systems, a reliable standby generator, and a sophisticated control building. Overseeing the construction as the general contractor is Haren, while the town's esteemed engineer of record is Withers & Ravenel.

This ECIA project component, presently in its concluding stages of design and permitting, encompasses the expansion of the Clayton-to-Raleigh pump station. This expansion is intended to facilitate the conveyance of a segment of the Town's untreated wastewater flow to the City of Raleigh's Neuse River Resource Recovery Facility. 

It's noteworthy that this pump station is strategically situated in close proximity to the Sam's Branch Water Reclamation Facility site. This capacity augmentation with the City of Raleigh and effectively manage wastewater flows until the Sam's Branch WRF becomes operational. It's imperative to mention that HDR serves as the Town's designated engineer of record for this initiative. 

This project component, currently under final design and permitting, includes expanding the Clayton-to-Raleigh pump station to convey a portion of the Town's raw wastewater flow to the City of Raleigh's Neuse River Resource Recovery Facility. 

This pump station is located directly adjacent to the Sam's Branch WRF site. The capacity expansion will allow the Town to fully utilize its contractual treatment capacity with the City of Raleigh and manage wastewater flows until the Sam's Branch WRF comes online. 

HDR is the Town's engineer of record.
