Project Description

WAGNN---IMG-010D&B provided engineering services for the design and construction of a 6.0 MGD water treatment facility for the Water Authority of Great Neck North (WAGNN).

The facility includes treatment for the removal of Volatile Organic Compounds (VOC’s) as well as chemical injection. VOC treatment includes two independent trains of packed tower aeration, each capable of treating 4.0 MGD, which was constructed upstream of four 20,000 pound granular activated carbon (GAC) filter vessels.

The treated water is treated with sodium hydroxide to raise the pH, sodium hypochlorite for disinfection and polyorthophosphate for corrosion control.

WAGNN---IMG-005D&B prepared the preliminary design report, contract drawings and contract specifications for this project. D&B assisted the Authority in obtaining approvals from the Nassau County Department of Health (NCDH) for construction and operation.
