The New Jersey Water Supply Authority is responsible for operating and maintaining the Round Valley reservoir for drinking water supply. As part of the Authority’s asset management program, it hired a team of internationally recognized experts to conduct a holistic review of the structural health of the Round Valley reservoir structures.
Based on the results and recommendations from this review, the Authority is making improvements to extend the operating life of the Round Valley reservoir. Design standards and construction techniques have evolved in the 50 plus years since the reservoir was built. Many structures of similar type to the Authority’s that were built in the same era also require periodic rehabilitation. The Authority’s plans for improvement of the reservoir structures will bring them to today’s state-of-the-art design standards.
The Authority will move forward with improvements to the Round Valley reservoir’s structures over the next few years. A Request for Proposals for design of these improvements was issued and the Authority entered into a contract with the Engineer of Record for the project, Schnabel Engineering. Schnabel is a national leader in engineering with highly specialized experience in analysis, design and construction support for the rehabilitation of existing structures. As Engineer of Record, Schnabel will be responsible for the design and quality assurance aspects of the project.
The Authority has also entered into a contract with Gannett Fleming to serve in the capacity of Owner’s Engineer. Gannett Fleming is a global infrastructure firm with more than 100 years of experience in planning, design, technology and construction management services. Gannett Fleming has been involved with the project since its beginning phases in 2014. In the capacity of Owner’s Engineer, they will oversee design and construction, consult with Authority Engineering Staff and act as an additional layer of Quality Control/Quality Assurance during the design and construction phases of the project.
The design and permitting phase of the project is underway. There are a number of project components that will be undertaken on different timelines. The first phase of the Round Valley project includes grouting of the abutments at the North and South Dams as well as dredging of the Intake Channel at the South Dam. These two component projects will be undertaken in 2019. The second, and final, phase of the project involves rehabilitation of all three embankments (North Dam, South Dam, Dike) and installation of new drainage features within each. Site preparation work for this phase is anticipated in 2019 and construction dates have not yet been established. These improvements will allow for safe reservoir operation for future generations.
