WaGate for Wastewater Treatment Plant in Great Neck

Owner - Great Neck Water Pollution Control District, Engineer – D & B Engineers & Consultants, Contractor – Bancker Construction, Sales Rep – Dave Heiner Associates| Great Neck, New York| Shut-off & Control

This project was undertaken to upgrade the Great Neck Water Pollution Control District’s existing 3.8 MGD wastewater treatment plant. The goal was to achieve the New York Department of Environmental Conservation’s required nitrogen removal on their effluent. The scope of the project increased the plant’s daily capacity from 3.8 MGD to 5.3 MGD to meet the new increased system demands of the Village of Great Neck.

During the removal and abandonment of one of the primary settling tanks a new 36” by pass line had to be installed in order to complete the new piping connections. work. A 36” WaGate SVM-TG with special eccentric flanges was supplied and installed for use on the new 36” pipe between the Influent Distribution Chamber and the new Primary Settling Tank.

The problem

As a part of critical infrastructure, it was imperative for the project to be completed on time as to not have any negative effect on the treatment process. The contractor was posed with several problems including time constraints on the project as well as suitable face to face dimensions of the valve flanges.

WaGate Great Neck

Solution

WaGate® Gate Valve

Having worked together previously, Bancker Construction inquired about possibly utilizing a WaGate on this application as they were facing product delays from other manufacturers. After going through a very rigorous submittal process and meetings between the owner, engineer, and contractor the WaGate product was approved.

The selected and approved product was a 36” WaGate SVM-TG with a 2” square nut operator. The valve was manufactured with eccentric flanges and special dimensions to accommodate the required lay length. Another added benefit of the WaGate is the HDPE and stainless steel construction which allow for the valve to be suitable for corrosive environments as well contributing to its lightweight. The 36” WaGate weighed in at 550 pounds where other traditional cast iron gate valves weigh closer to 8,000 pounds.

After approval the valve was delivered to the site within 4 weeks of receipt of the purchase order. This was a welcome relief after being quoted between 14-18 weeks for delivery. Installation was done in May of 2021.  Approval of the WaGate allowed for the project to move ahead without any material delay.
