Outcomes
  • ERI survey results assisted in selection of potential exploration well sites
  • A new 220-gpm water supply well was constructed in the NAWC’s service area
  • Provided final design of well construction and water treatment facilities.

For more than two decades, Gannett Fleming has provided consulting engineering services in connection with operation, management, and improvement of the Newtown Artesian Water Company’s (NAWC’s) water distribution system. In this capacity, Gannett Fleming conducted groundwater resource development planning for NAWC, who was actively seeking new groundwater supplies. 

NAWC serves Newtown Borough, Newtown Township, and part of Middletown Township in Bucks County, Pennsylvania. The water distribution system serves approximately 10,000 customers in three service levels at an average daily demand of approximately 2.4 mgd.

What We Did

Our firm’s services included the review of existing geologic and hydrogeologic information, surveys of bedrock fracture traces, assessments of groundwater availability in proximity to stressed stream basins, review of existing well yield and water quality characteristics, preparation of mapping to geographically compile hydrogeology, land use and property characteristic in the study area, preparation of groundwater investigation plans for regulatory agency review and approval, and planning surface geophysical surveys.

Additional services included two-dimensional electrical resistivity imaging (ERI) surface geophysical surveys. Using the results of the ERI surveys to select potential exploration well sites, a new 220-gpm community water supply well was constructed in the NAWC’s service area. To develop this new well, our firm’s services included geologic logging; borehole video; final design of well construction; planning and completion of an aquifer pumping test; well-water quality testing of bacteriological, organic, inorganic, and radionuclide constituents; analysis of observed and anticipated drawdown influence on nearby wells and streams; and the design of water treatment facilities.

Key Features

  • New well site location and construction
  • Final design of well construction and water treatment facilities.
