Water Main Replacement Project

Water Main Replacement Project

The Water Department, in collaboration with its engineering consultant H2M and independent contractors, is undertaking a multi-million-dollar upgrade to the water lines and valves in Central Nyack, West Nyack, and select streets in the Village of Nyack. This project involves the replacement of water mains and lateral lines, which will require excavations in the roadways.

Once excavation work is completed, the trenches will be filled in. The Water Department is working closely wit h Clarkstown Highway Department, to ensure that the re-paving of trenches in Central Nyack and West Nyack meets the standards outlined in town-issued permits. Streets in the Village of Nyack will also be repaved as part of the Village's annual paving program. 

Phase A of the Water Main Replacement Project was successfully completed between 2020 and 2022. Phase B construction has started November 2024. 

Update – 11/20/24: Phase B Construction

Phase B of the Water Main Replacement Project is now under construction in West Nyack and the Village of Nyack, starting with Central Ave and Francis Ave. Work will then progress to Jefferson Ave and Marion St in the coming weeks. This phase focuses on replacing the oldest, most failure-prone water lines in the Village.

Project Details:

1. Insertion Valves: The first step involves the installation of insertion valves in the water mains to allow proper control of the water flow (turning the mains on and off).
2. Trenching & New Water Main: Following this, contractors will trench the area and lay down a new water main parallel to the existing main.
3. Service Line Installation: Service lines will then be connected from the new main to each home, after which the new main will be activated and the old main abandoned.

Minimizing Disruption:

• Contractors will maintain access to driveways whenever possible. Steel plates will be placed over road openings overnight when work is not in progress to ensure safe passage.
• Temporary street closures will occur during the work.

Project Oversight:

We have partnered with the highly reputable contractor, Fletcher Creamer & Sons, overseen by H2M Engineering. An H2M inspector will be on-site at all times, overseeing the work flow and ensuring that it meets all quality standards. The Nyack Water Department staff collaborates closely with the team, providing essential mark-outs of existing water infrastructure and supporting the project in various capacities.

Restoration:

• Fletcher Creamer & Sons will handle backfilling, compacting, and repaving the road openings. If necessary, they will return to level the new pavement before the Village's annual paving program repaves the streets entirely, expected to take place in the summer or fall of 2025.

Phase B of the Water Main Replacement Project

The following streets are scheduled for water main work during Phase B of this project, with construction taking place from Fall 2024 to Summer 2025:

• Frances Ave
• Central Ave (Fifth to Sixth)
• First Ave (N Franklin to Broadway)
• Jefferson Ave
• Marion Ave
• Bridge St
• Park St
• Summit St
• Doscher Ave(Hobe to Western Highway)
• Hobe St (Doscher to Patterson)
• Patterson Ave (Green to Hobe)
• Benson Ave (West to West Nyack Rd)
• Klein Ave (West to West Nyack Rd)

PFOS Treatment Project

The Water Department is upgrading its treatment plant to effectively remove PFOS/PFAS contaminants in compliance with state and federal regulations. Designed by H2M Engineers, this important project is nearing completion and is expected to go out to bid in January 2025. The total project cost is approximately $6.7 million, with a significant portion funded through grants and New York State financing. 

PFOS Project Update – 11/20/24

The design for the PFOS/PFAS treatment process is largely complete, pending approval from the Department of Health. The project is on track to be ready for competitive bidding in January 2025, with construction expected to begin shortly thereafter.
