Water Main Installation: Celler Avenue


September 2017

As part of its continuing effort to improve water service for domestic use and fire protection, the Water Authority of Western Nassau County (the "Water Authority") will be installing approximately 2,600 feet of new 12-inch cement-mortar lined ductile iron pipe.

This project involves the installation of a new transmission main in Celler Avenue in New Hyde Park from the Water Authority pumping station on Soma Street to an existing transmission main on Hillside Avenue.  There are two (2) wells at the pump station which presently pump into an 8-inch distribution main on Soma Street from 10-inch discharge piping at the station.  This existing piping configuration creates a bottleneck and a disturbance of the flow by introducing a large amount of water into a smaller main.  This project, once completed, will allow both wells at the station to be pumped at the same time something that cannot be done with the existing 8-inch water main.  It will also provide a way to move water to other areas of our service territory when needed, provide a better water flow and decrease the possibility of discolored water in the area when the wells at the station are turned on or shutdown.

This installation project is scheduled to start on or about September 13th, 2017.  Work each day will begin at 8:00 AM and end at 5:00 PM, at which time all construction will have been completed and the road opened for traffic.  The work is being performed by the Water Authority's board approved contractor, Merrick Utility Associates.  During the installation certain customers may experience brief service disruptions, temporary changes in water pressure, or slight water discoloration.  Any customer whose water service must be temporarily interrupted will be notified in advance by Water Authority employees with more specific door hangers placed at each affected customers' residence.  Water discoloration, when experienced, is usually of short duration and is easily cleared by briefly running the cold water for approximately 5 minutes.

Water Supply Improvement

Wellhead Treatment for VOC Removal
Phase 1 - Stations 15A & 15C/E
Anticipated Completion Date: Fall 2017

Project Scope

As part of our commitment to providing a safe and reliable supply of high quality drinking water for our customers, we are bringing select wells back into service upon installation of wellhead  treatment for the removal of volatile organic compounds (VOCs) commonly found in Long Island's groundwater. By increasing the reliability and availability of drinking water supply in our service area, we will be better able to serve our customers and have more resources ro respond to emergency situations.

Phase 1

Station Number 15A:  The existing building will be replacedwith a new energy efficient building and setup for off-site future wellhead treatment.

Station Number 15 C/E: Construction of a new energy efficient treatment building, rehabilitation of the existing building, and installation of a new emergency standby generator.
