Westchester County has officially completed the Outfall Jetty Rehabilitation project at the Mamaroneck Wastewater Treatment Plant, ensuring the protection of vital wastewater infrastructure and restoring public access to the Harbor Island Park jetty. The over $7 million project was fully financed through the County’s capital budget, addressing decades of deterioration to the jetty’s steel sheet piling and providing long-term stability for the outfall pipe discharging treated effluent into the Long Island Sound.
The Mamaroneck Wastewater Treatment Plant relies on a 60-inch diameter outfall pipe extending approximately half a mile into the Sound. Initially constructed in the 1930s and upgraded in subsequent decades, the steel sheet piling jetty had experienced extensive corrosion, requiring fencing to restrict public access. This rehabilitation effort, initiated in September 2023, restores the structural integrity of the jetty and reopens walkways, benches, and viewing areas for public use.
Westchester County Executive Ken Jenkins said: “Completing this rehabilitation project underscores our dedication to infrastructure resilience and community well-being. By investing in the long-term protection of the outfall system and revitalizing public space, we are enhancing the quality of life for Westchester residents while ensuring our wastewater facilities continue to operate safely and efficiently.”
Department of Environmental Facilities Commissioner Vincent Kopicki said: “The completion of this project is a testament to the hard work and coordination of multiple agencies and stakeholders. By reinforcing the jetty’s structure and protecting the outfall pipes, we are ensuring the long-term reliability of the Mamaroneck Wastewater Treatment Plant. This investment is critical to safeguarding public health and preserving the natural beauty of the Long Island Sound.”
Department of Public Works Commissioner Hugh Greechan said: “Rehabilitating a structure that plays such a pivotal role in wastewater treatment operations and public recreation required exceptional coordination and planning. This project represents a major step forward in ensuring the longevity of the Mamaroneck Wastewater Treatment Plant’s operations while preserving valuable public amenities.”
Village of Mamaroneck Mayor Sharon Torres said: “We are grateful to Westchester County for their leadership and dedication in completing the Outfall Jetty Rehabilitation project. This effort strengthens critical infrastructure and restores a beloved part of our community’s waterfront. The improvements to the jetty and park will enhance the experience for all who visit, reinforcing our shared commitment to preserving public spaces for future generations.”
With the jetty fully restored and open to the public, Westchester County continues prioritizing infrastructure projects that balance operational needs with environmental stewardship.
