Frequently Asked Questions

Q: What is the project?

The Round Valley Reservoir Structures Refurbishment and Resource Preservation Project is making improvements to extend the operating life of the Round Valley reservoir.

Q: Who is in charge of the project?

The project is controlled and led by The New Jersey Water Supply Authority.

Q: What is the project going to do?

The project will refurbish the reservoir structures with state-of-the-art design standards and construction techniques. The project will extend the operating life of the Round Valley reservoir, which is the largest drinking water supply by volume in New Jersey.

The success of the project will be vital to the State’s ability to sustain prolonged droughts by increasing this vital reservoir’s structural durability. This improved resilience will help ensure supplies of drinking water for future generations.

Q: When will the project start and end?

The New Jersey Water Supply Authority anticipates that major construction work will begin in 2018, with certain parts of the project potentially beginning in 2017. Additional project timeline details will be announced as soon as the information is available.

Q: Will the project affect people who use the reservoir for recreational activities?

Construction efforts are scheduled to minimize disruption to the public’s use and enjoyment of all that the Round Valley reservoir has to offer; however, certain disruptions may be unavoidable. The details of these activities will be announced as soon as the information is available.

It is possible that project efforts will require the lowering of the reservoir level, which could impact boaters and fishermen. The reservoir level may also be naturally lowered during drought conditions when more water is used, as occurred in 2016. The New Jersey Water Supply Authority adds water back into the reservoir by pumping when conditions permit. Whether additional, Project-related lowering will be necessary is yet to be determined. More information about reservoir levels, releases, and the current drought status, is available on the Authority's website.

There may also be temporary closures to park trails and local roads. All closures will be announced on the project website as soon as the information is available. Information will also be shared through local outreach efforts.

Q: Will the project affect local drinking water usage?

The Round Valley reservoir is connected to natural river systems, which enables water to be stored and moved around within the reservoir’s service area of central New Jersey. Balancing the needs of everyone that relies on this water is a critical part of the New Jersey Water Supply Authority’s work, especially given the drought that began in 2016. The reservoir provides a drinking water source for 1.5 million residents in central New Jersey and decisions to lower the water level are taken very seriously. With this in mind, the Authority is scheduling the project in close coordination with the Division of Water Supply and Geoscience of the New Jersey Department of Environmental Protection.

Round Valley reservoir is part of a larger water supply system supply called the Raritan Basin system, which also includes the Spruce Run Reservoir. Additional information about the Raritan Basin system can be found on the Authority’s website.

Q: Will there be any public meetings?

Yes. The New Jersey Water Supply Authority will host one Public Information session to explain the project and invite comments and questions from the attendees. For more information, please click here.

Q: How can I contact a representative for more information?

Q: What are the conditions at the Round Valley boat launch?

A: The Round Valley boat launch is maintained by the NJ Department of Environmental Protection’s Division of Fish & Wildlife. The Authority has no additional information on the conditions at the boat launch. As reservoir water levels fluctuate, the Division of Fish & Wildlife makes efforts to accommodate boats. Real-time reservoir water level information is available at NJWSA Operations Report and
