A major water infrastructure upgrade has been completed along Montauk Highway in East Moriches, improving circulation and water quality for hundreds of local residents and businesses. The project installed approximately 3,200 feet of new ductile iron water main to connect existing lines and eliminate dead ends in the system.
“This project enhances both water quality and reliability for the East Moriches community,” said Suffolk County Water Authority Chief Executive Officer Jeff Szabo. “By eliminating dead ends, we’ve improved circulation and ensured residents continue to receive the highest quality drinking water possible.”
The new connections allow water to move more freely through the system, reducing the risk of sediment buildup and stagnant sections that can affect taste and clarity. Areas without steady flow often require additional flushing to maintain standards, but the improved network will help minimize that need.
Ductile iron pipe, used in the project, is known for its durability and resistance to corrosion—qualities that ensure a longer service life and greater reliability for customers. Engineers said the upgrade strengthens the community’s overall water infrastructure while supporting future growth in the area.
The East Moriches project is part of a broader effort by the Suffolk County Water Authority to modernize its distribution network across the county. Similar projects are underway in several communities to replace aging mains, improve system pressure, and ensure a resilient supply capable of meeting increasing demand.
The Authority, which serves about 1.2 million residents, operates on a not-for-profit basis without taxing power, investing revenues directly into infrastructure improvements and public health protection. Though surrounded by sea water, Long Island is blessed with an underground aquifer of excellent quality.
For East Moriches residents, the completion of this project means cleaner, better-tasting water and a stronger system prepared to meet demand for decades to come.
