Project Description

The Newtown Creek Wastewater Treatment Plant in Brooklyn, NY is a significant infrastructure project that involved the construction and renovation of various facilities. It included the building of new grit, aeration, and sedimentation tanks, as well as the remodeling of existing facilities. Additionally, control and administration buildings were constructed, along with the installation of piers to support air main and odor control piping. Carpenter & Paterson, a company specializing in pipe supports, played a vital role in the project by providing engineering, materials, and fabrication for the pipe support systems.


One of the main challenges faced during the project was designing supports for the 62" Odor Control piping. This specific piping system was located outside, and factors such as location, elevation, and roughing complicated the design process. A comprehensive stress analysis was necessary to determine the load and movement required to anchor, restrain, and allow for expansion and contraction due to various process and environmental conditions, including wind, snow, and seismic activity. Overcoming this challenge was crucial to ensure the stability and functionality of the piping system.

The Support We Provided

Carpenter & Paterson delivered significant value to the project by providing comprehensive support solutions for the wastewater treatment plant. With their expertise in engineering and fabrication, they were able to design and manufacture the necessary pipe supports to meet the specific requirements of the project. The use of Type 316 Stainless Steel slide supports and guides provided exceptional corrosion resistance, which was crucial in a facility processing 1.8 million gallons of sludge per day. The meticulous review of designs, calculations, and fabrication by Carpenter & Paterson's Professional Engineer demonstrated their commitment to delivering high-quality products and ensuring the success of the project.


The support provided by Carpenter & Paterson played a pivotal role in the successful completion of the Newtown Creek Wastewater Treatment Plant project. By delivering over 11,700 supports across two contracts, Contract 35G with the SPMP Joint Venture and Contract 47G with the SPII Joint Venture, they ensured the stability and functionality of the pipe systems within the facility. The stainless steel cladding on the "egg" digesters offered exceptional corrosion resistance, further enhancing the durability and longevity of the infrastructure. Carpenter & Paterson's involvement and expertise in providing pipe supports contributed to the overall success of the project and the efficient operation of the wastewater treatment plant, benefiting the community it serves.
