1867 U.S. Patent 69,762 2 I..have invented a new and useful improvement in Well-Points.
1889 Jrnl. New Eng. Water Wks. Assoc. 4 219 I used fourteen 1½-inch pipes, which were driven equidistant about the excavation to be made with the ordinary perforated well point.
1946 H. L. Garver Safe Water for Farm 17/1 2- to 3-inch extra-strength wrought pipe is cut into convenient lengths, provided with a well point, and driven as shown.
1951 Engineering 4 May 536/3 The consulting engineers considered..that lowering of the ground-water level by means of well-points would be the most efficient method of keeping the excavation dry.
2008 Ecol. Applic. 18 794/1 Small steel well points..were installed in four locations.
