Sand and Gravel WellsAugust 9, 2017
Chazen conducted a siting study and then designed and installed municipal sand-and-gravel wells for the Town capable of supplying more than 1,000 gallons per minute.
To site the wells, Chazen conducted a detailed soil boring program on a parcel of land near the Wappinger Creek. The parcel was found to contain both clay areas and sand-and-gravel zones. Three most-probable sand-and-gravel horizons were selected for installation of candidate production wells.
Chazen specified casing and well screen designs and oversaw installation of the wells and subsequent well development leading to production of clear water flows from each test well.
Chazen then planned and oversaw pumping tests to evaluate available well yields and water quality. Test results were summarized in a hydrogeologic report within an engineering design report prepared by Chazen. Site infrastructure including a water treatment plant and associated distribution lines were also designed by Chazen.
