Town of New Hampton, NH (Public Safety Complex)

The Project

The Town of New Hampton, New Hampshire recently completed construction of a new Public Safety Complex housing for both Police and Fire Departments. A 30,000-gallon water cistern was built into the new facility to provide water for the fire protection (sprinkler) system and to fill fire trucks as needed. In order to reduce the impact to the small public water system serving the Town, design of the system called for the installation of an on-site well to provide a source of non-potable water to fill the cistern.

EGGI evaluated the hydrogeology of the project site using a combination of geologic mapping and geophysical surveys to determine whether a shallow sand and gravel deposit could provide enough groundwater resources to meet the non-potable water supply demands. A shallow sand and gravel well would be significantly less expensive to install compared to a deep bedrock well.

Status/Results:

EGGI selected a well site in the sand and gravel deposit based on where geophysical surveys indicated the depth to bedrock was greatest.  A shallow three-inch-diameter PVC well was installed in the local sand and gravel aquifer that yields approximately 10 gpm.  Testing of this new well is ongoing, though the well is expected to be able to provide sufficient water to fill the new cistern, saving the Town thousands of dollars in drilling expenses.
