PORTFOLIO

CNG Fueling Station at
Suffolk County Water Authority

Project Location: Oakdale, NY
Client: Suffolk County Water Authority / Air & Gas Technologies

Nelson + Pope was retained by Air & Gas Technologies, a turn-key contractor, to provide Professional Engineering Services associated with a new Compressed Natural Gas (CNG) fueling station at the Suffolk County Water Authority’s facility in Oakdale, NY.  The Water Authority desired a fleet fueling time-fill station that slowly fills the trucks overnight, a strategy to reduce operating costs through smaller compressors and off-peak electrical consumption.  N+P assisted the Authority with sizing and selection of the CNG compressors.  N+P’s design for the 150 scfm station included a natural gas dryer, two compressors, CNG storage tubes, and a time fill panel.  A separate electrical equipment pad included a new distribution panel motor starter panel, a control and communications panel, and a low voltage panel for miscellaneous site power.  Fueling is for the fleet, and the station features two fast-fill dispensers for immediate fueling, and 24-time fill dispensers for overnight fueling. N+P’s design included modifications to an existing truck shelter to house the time fill dispensers and comply with NFPA 52. In addition to preparing the site layout and code compliance plans, N+P’s services included all electrical and communications wiring and pipe sizing for both low and high pressure natural gas piping.  The plans were prepared and issued for permit and construction.
