Project Overview
The Pequannock Aqueduct Rehabilitation is a critical infrastructure upgrade aimed at preserving and extending the life of Newark’s historic water delivery system. Dating back to the 1880s, the twin 42- and 48-inch aqueducts have long served as a backbone for the city’s high-quality drinking water. This multi-phase effort focuses on the first six miles of upstream piping, addressing operability, sustainability, and long-term performance.
International Valve supplied high-performance Vent-Tech air release and vacuum relief valves—key components that protect pipeline integrity, optimize flow performance, and safeguard operations in the event of seismic activity.

Challenge Faced
While the system remains one of the most effective in the state, age and regulatory pressures have prompted urgent upgrades. With federal and state mandates requiring improved safety, security, and environmental compliance, the city needed a reliable valve partner to ensure operational integrity and high-performance air/vacuum relief under demanding conditions. The scale of the valves required—some of the largest International Valve has produced—adds a layer of precision and complexity to the project.

Solution Provided
International Valve is supplying large-diameter Vent-Tech air release and vacuum relief valves engineered for high vacuum relief performance and zero-pressure sealing. These valves will help maintain safe, reliable operation throughout the aqueduct’s critical upstream segments. The project marks one of International Valve’s most demanding valve builds to date, reflecting our unmatched engineering capabilities and support for legacy water systems.
