PhotoThe Richard Stockton Geothermal Project was begun in the spring of 1994.

As per the specifications of the project engineer, Vinokur-Pace Engineering of Jenkintown, Pa, one of the main parking lots was dug up and prepared for the installation of four hundred wellholes.

These wells were drilled using commercial drilling rigs that are used for drilling wells used to supply drinking water for homes and businesses that are not near city water hook-ups.

Each well hole would receive two 425 foot long pieces of polypropylene tubing, attached by a "U-joint" at the bottom of the well. Each well would be connected in series, creating what, at the time, was the world’s largest closed-loop geothermal space conditioning system.

The well-field uses technology developed by the natural gas industry, including the ability to "field-splice" the polypropylene tubing as it is being assembled in the well-field.

The manifold house serves as a focal point for data generation and collection. From there, the loop is connected to the main pumps, housed in the pump room adjacent to a central location in main academic area.

These 125 H.P. units are controlled by variable speed drives to control the speed of the water used to transport the geothermal power of the earth’s mass.


After the well field was completed, the rooftop Heat Pump units were then air-lifted into place in January of 1995. These units were manufactured to spec by Trane, and lifted onto the rooftops of the academic buildings with the aid of a Sikorsky helicopter.
